Passive desktop speakers 1“ silk tweeter 5.5” aramid fiber woofer Magnetic grilles Gold-plated speaker terminals With their handcrafted cabinets and hand-tuned sound, the HDP6 passive speakers are a perfect match for stereo receivers, integrated amplifiers, tube amplifiers and anyone in search of the “perfect sound experience”. A feast for the eyes and ears The HDP6 is one of those rare music systems that sound even better because they look good. The sealed, handcrafted wood veneer cabinets absorb sound waves and reduce echo and reverberation for a more natural and balanced sound, without harsh or artificial tones. They are also very robust. The real wood veneer can withstand years of use and abuse and is less susceptible to scratches and dents than synthetic materials. Plus, Audioengine sources their wood veneer from responsibly managed forests that are harvested in a sustainable and environmentally friendly way. Sure, they look great on your shelf, but the HDP6 is much more than just a pretty face. Handcrafted with your music in mind Every music system built with other people's parts sounds like someone else's music system. Audioengine doesn't rely on what's on the shelf or lying around in the factory. They develop, build and tune everything that goes into their music systems by hand. What they don't build themselves, they have manufactured to their exact specifications. Audioengine has total control over every step of the process. This has allowed them to produce high-end audio systems that are not too expensive for more than 15 years. Impressive performance range The bottom line in nerd speak: Audioengine uses audiophile-grade, ferrofluid-cooled silk dome tweeters. Silk tweeters can withstand high power levels and the edge-controlled design ensures a very smooth frequency response. The woofers are made of aramid fiberglass with rubber surrounds. The HDP6 woofers are housed in cast aluminum frames that ensure high rigidity and improved heat dissipation. The bottom line for the rest of us: they look great, sound even better and are built to last a long, long time. Specifications: Type: 2-way passive speaker system, rear design, power amplifier or AV receiver required Driver: 5.5“ aramid fiber woofer 1” silk dome tweeter Inputs: Gold-plated terminals Frequency response: 50Hz - 22kHz ±1.5 dB Dimensions: 25.15 x 18.54 x 30.23 cm Weight: 5.67 kilograms

Passive loudspeaker 2-way bookshelf speaker Real-wood veneer 4-inch aramid fibre woofer 0.75-inch silk dome tweeter With sleek, modern exteriors and cutting-edge technology inside, Audioengine's P4 passive loudspeakers are perfect for stereo receivers, integrated amplifiers and tube amplifiers. Perfect for old school, new school, or even middle schoolThe P4 passive loudspeakers give you award-winning Audioengine sound in a bold, modern package that connects to your trusty integrated amplifier or stereo receiver.New or old, Audioengine designed the P4 passive loudspeaker to work with both digital or hybrid amplifiers and stereo receivers, integrated amplifiers, and tube amplifiers. The P4 has a 4 ohm impedance rating, meaning it's designed to handle higher power. At the same time, it still sounds great when connected to a receiver or integrated amplifier with 4, 6, or 8 ohm speaker output impedance. Audioengine knows you're going to love the P4 Passives, and here's why 2-way front-firing passive design – sound comes out primarily from the front of the speaker, and you don't have to worry about sound bouncing off the walls behind the speaker.Handcrafted enclosures - offer superior quality compared to their mass-produced competitors. Silk-dome tweeters and aramid-fibre woofers - high-quality parts that reproduce sound excellently and are durable. Stable enclosures: To minimise unwanted resonance and distortion, Audioengine enclosures feature thick, resinous MDF walls with extensive internal bracing. Heavy sound-dampening material is used to reduce unwanted sound reflections within the enclosure. All cabinet edges are radiused, which not only looks good but also reduces high-frequency diffraction effects at the front sound walls. The P4 enclosure includes tuned ports for the front ports. Furniture-like finishesThe P4 enclosures are available in a variety of attractive finishes, including bamboo veneers and high-gloss white paint, offering a wide range of options to complement any interior design. Custom componentsAudioengine designs and manufactures its own speaker drivers and other critical components. In other words, the P4 is not a system built with off-the-shelf parts, but rather contains custom components engineered to our specifications. What Audioengine doesn't directly manufacture in their factories, they've had made to their specific designs and parts, such as circuit boards, transformers, magnets, and cable harnesses. Based on studio monitor designsStudio monitor loudspeakers are used by producers and engineers in recording and production studios. They are designed with a flat frequency response, which allows the audio engineer to create a final mix so that the recorded music will sound good on most other speakers as well. While Audioengine loudspeakers are not designed to be near-field studio monitors, Audioengine applies the same high-quality technologies, components, and design philosophies to all Audioengine loudspeaker systems. Driver Designs Audioengine employs audiophile-grade silk-dome tweeters cooled by ferrofluid and featuring neodymium magnets. The silk domes hold up well at high power and the edge-driven design ensures very smooth reproduction. The woofers are made of an aramid fibre-glass fibre weave with rubber surrounds. Aramid fibres are obviously very strong, which means that the woofer retains its shape even at high levels. The materials and construction of the speaker are robust enough to withstand heavy use, so no speaker grilles are required. In other words, Audioengine has done its homework on the speaker drivers, and they'll still sound and look great years from now. Shielding Both drivers feature internal magnetic shielding, so you can place the speakers within inches of a video monitor. This shielding also provides protection for hard-drive-based digital music players. Technical data Type - 2-way passive loudspeaker system Drivers - 4‘ aramid fibre cone bass driver, 0.75’ silk dome tweeter Terminals - Gold plated Frequency response - 60 Hz-22 kHz ±1.5 dB Nominal impedance - 4 ohms Cabinet material - 13mm MDF Recommended Amplifier Requirements-10-125 W per channel Dimensions - HWD - 23.4 cm x 14 cm x 16.5 cm Weight-2.7 kg

Thanks to the high-resolution digital inputs and LDAC support, the SA1 is both Hi-Res Audio and Hi-Res Audio Wireless certified. *Bluetooth version: 5.4 Multiple built-in sound presets Supports app control The SA1 comes with eight sound presets and allows you to save up to three custom PEQ setups, all of which can be adjusted through the FIIO Control app. In addition to the typical pop, jazz, classical, R&B, and dance sound presets, there is also a specially-tuned monitoring-style curve that compensates the frequency response curve to a flat line, allowing the SA1 to transform into active desktop studio monitor speakers. *For detailed instructions on PEQ setup, please refer to the SA1 quick start guide and the official FAQ. 3.5-inch wood fiber woofer Compact yet powerful Although the SA1 is an entry-level product, its woofer is the same 3.5-inch size as that of the SP3/SP3 BT and is made of the same wooden fiber pulp manufacturing process as in FT1 wood headphones. The pure pulp fiber diaphragm is both lightweight and sturdy, and outputs rich sound. By adjusting the pulp material, ratio, and the proportion of long and short fibers, we made the diaphragm more rigid and fine-tuned the sound. The wooden fiber diaphragm has a thick and rich sound, with dense and lush vocals. Due to these advantages, it is no wonder that other well-known brands utilize this kind of driver in their speakers even now. Additionally, the 3.5-inch woofer is paired with a large 75mm flexible suspension, allowing that driver to achieve bass extension down to 65Hz. 3/4 inch aluminum-magnesium alloy dome tweeter Silky smooth to your ears The SA1 uses a monitor-grade aluminum-magnesium diaphragm dome tweeter that provides with crisp, clear sound. It brings a uniquely enjoyable listening experience with plenty of detail. Texas Instruments digital amp Guaranteed good sound Being a desktop active speaker, the internal amplification is extremely important. The SA1, like the SP3/SP3 BT, is equipped with two Texas Instruments TI TPA3118 Class D digital amplifiers. The main and auxiliary speakers each are driven in four ways, with woofer output power up to 20W*2 and tweeter output power up to 5W*2. The TPA 3118 has high conversion efficiency and features low noise, ensuring the purity of the audio signal. Acoustic design 2.0 Active electronic two-way crossover The SA1 is designed to be a set of professional active speakers. The crossover point is set at 3.5kHz, which best suits the characteristics of the drivers, power supply, and circuitry – maximizing the SA1’s sound quality. The SA1 employs a two-way second-order active filter circuit to enhance the flexibility and control precision of the crossover. This crossover design effectively isolates each driver's signal from the others – leading to reduced intermodulation distortion, avoided driver overload, and significantly improved power efficiency. Built-in phono preamp The SA1 is equipped with a built-in phono preamp, designed with standard RIAA equalization in order to ensure faithful reproduction of sound from your vinyl records. When using a vinyl turntable without a built-in preamp (vinyl turntable only has PHONO OUT), you can switch the SA1 to the PHONO setting to use the internal SA1 phono preamp. If the vinyl turntable already has a built-in preamp (such as the FIIO TT13), simply switch the input toggle to RCA IN.Subwoofer out Instantly transform into a HiFi 2.1 system Due to popular demand, the SA1 has been equipped with an RCA subwoofer output. Use the SUB OUT connector to connect to an active subwoofer to form a 2.1 system, for better bass performance even in large rooms. MDF cabinet A natural sound The SA1’s cabinet is made of high-density MDF with a thickness of up to 12mm. The top and sides of the cabinet adopt a 9mm thick imitation solid wood veneer, which can effectively reduce sound resonance for a purer and more natural sound. To simplify the frontal design of the SA1 looks more concise and to achieve better sound, the SA1 uses a rear guide tube design that allows for bass extension down to 65Hz, giving these compact speakers a big punch. Physical knobs For convenient operation Two large physical knobs, one of which is adorned with an RGB light indicator, and a large button on the right side of the main speaker make operating the SA1 faster and easier. Signal input button and volume adjustment knob: Turn clockwise to increase volume; Turn counter-clockwise to decrease volume; Short press to switch between inputs. Bass adjustment knob: Turn clockwise: Bass enhancement; Turn counter-clockwise: Bass attenuation. Power switch: Power on (long press): RGB light on; Power off (short press): RGB light off. Custom infrared remote control included Fully-functioned control 1. Standby button 2. Mute button 3.

FiiO SP3 BT Active Hi-Fi Desktop Bluetooth Speaker 3.5-inch carbon fibre mid-woofer CrossoverAsymmetrical internal and external magnetic circuits Directional acoustic waveguides Double diffused S-shaped port tube 1-inch silk tweeter TI power amplifier 2x30+2x10W output power Qualcomm QCC5124 Bluetooth chip Supports high-resolution Bluetooth codecs including LDAC/aptX Adaptive Hi-Res Wireless certified Tiny volume of 2, 35L Die-cast liquid metal enclosure LED lighting effects Exclusive stand with 7-degree elevation High-quality exclusive cables True audiophile quality The SP3 Series uses a 3.5-inch carbon fibre woofer that is larger than typical products in this class, producing a big sound for such a small desktop speaker. These larger woofers have an inherent advantage over smaller woofers in terms of dynamics, projection of a larger soundstage and other sonic characteristics. Whether for films or music, this woofer is capable of expressing the size of the sound even at higher volumes. Carbon fibre is extremely strong and rigid, yet lightweight - the ideal characteristics for a speaker driver. The low weight of carbon fibre allows the woofer to transient quickly, while the high strength and stiffness of carbon fibre reduces non-linear distortion by minimising unwanted secondary vibrations as the driver moves during sound production. Overall, the carbon fibre material of the woofer contributes to a faithful sound reproduction and lets you immerse yourself even more intensively in your high-fidelity experience. Each carbon fibre in the SP3 series is only 0.007 mm thick - as thick as a single hair. These fibres are woven together, which helps to improve sound quality by ensuring a wrinkle-free cone and making the cone stronger and more resistant to cracking after prolonged movement and use of the driver. "To achieve a better sound, we use a special damping rubber for the woofer to obtain a transparent sound. This allows for realistic and detailed vocal reproduction as well as a very controlled and fast bass." Allen Chief Expert of FIIO Audio R&D Centre Treble performanceIn an active desktop speaker, the tweeter often plays a crucial role in the reproduction of fine musical details, instrumental overtones and overall treble resolution. Unlike many other active desktop speakers that use a ¾-inch tweeter, the SP3 series utilises a 1-inch tweeter that can produce frequencies of up to 35 kHz. The tweeter's copper-clad KSV aluminium voice coil ensures that ultra-high frequencies are not compressed even at high volumes - the result is better high-frequency reproduction even with off-axis listening and high-resolution treble with a natural timbre. With the SP3 series, you can hear even the most subtle vibrations of instruments. Robust performance To ensure that the 3.5-inch carbon fibre woofer produces really powerful bass and that the SP3 series can unfold its full potential, the development team has developed an asymmetrical system of internal and external magnetic circuits. An additional magnet has been placed in the centre of the SP3 Series to form an inner and outer magnetic circuit, improving the strength of the magnetic field generated and allowing a magnetic flux of up to 1.2 Tesla. This is the powerful driving force behind the driver that gives the SP3 Series its dynamic sound. In addition, the asymmetrical internal and external magnetic circuit systems help to reduce non-linear distortion across all frequencies, so that good sound is always available, no matter what music you listen to. Captivating sound that starts with the details Double-diffused S-shaped bass reflex tube After dozens of different designs, FIIO engineers finally developed the innovative "double-diffused S-shaped bass reflex tube" that allows the SP3 Series to achieve its goals of being compact while still producing high-quality sound. Firstly, this bass reflex tube has a much smaller cross-section than typical bass reflex tubes, allowing the SP3 Series to maintain a small volume. Secondly, FIIO engineers have carefully designed the "S" shape of the bass reflex tube to maximise smooth airflow and minimise turbulence. Finally, damping has been specifically applied to the inlet and outlet of the tube to reduce audible noise and ensure pure, robust bass quality. All in all, the SP3 Series will effortlessly immerse you in your music thanks to its ability to accurately reproduce sound effects. Create your exclusive hi-fi theatre For outstanding sound quality, the FIIO SP3 series has been specially tuned and designed to ensure that the sound waves reach the listener in the best possible way. The tweeter is precisely angled so that the sound waves are transmitted to the listener in an off-axis range of 0 to ±15° with essentially no loss, so that the listener is not tied to a specific position and speaker placement becomes more convenient. In addition, the horizontal stripe pattern in front of the tweeter has been designed to allow the sound waves emanating from the tweeter to propagate better in the room, which significantly improves the perceived soundstage and better conveys the illusion of actually being in a large concert hall. Wireless transmission, always online Qualcomm QCC5124 Bluetooth chip The SP3 BT uses the Qualcomm QCC5124 Bluetooth chip, which is able to process high bit rates stably and consistently thanks to its dual DSP and dual-core design. *Bluetooth 5.0 version Wireless freedom, but with wired-level sound quality The FIIO SP3 BT supports multiple high-resolution Bluetooth codecs such as LDAC/aptX Adaptive/AAC, giving you the freedom and flexibility to choose. When using LDAC, you can experience a high bit rate of up to 990kbs so you can hear every detail of your music. *All codecs supported by the SP3 BT can be found in the technical specifications. Now the mood is right to play music The FIIO SP3 BT features new Type-C/COAX/OPTICAL inputs that allow easy communication between your source and the speakers. Play your music easily and instantly, whether you use the modern USB Type-C connection or the proven COAX and OPTICAL inputs. Your speakers, your sound Supports 10-band parametric EQ To further enhance your SP3 BT listening experience, the speakers have been designed to work fully with the FIIO Control APP/FIIO Music mobile apps. After a successful Bluetooth connection, the mobile apps allow you to fine-tune your sound, e.g. customise the device name and set the Bluetooth codecs to be used. The biggest highlight of the app, however, is the 10-band parametric EQ, which allows you to adjust the Q value, gain and other parameters for each band. Dynamic or quiet, just as you like The SP3 BT has a standby wake-up function, i.e. if no signal input is detected within 20 minutes, the SP3 BT automatically switches to standby mode; if a signal input is detected, the SP3 BT automatically switches to playback mode. An automatic playback pause function makes the speaker more intuitive for your needs.The audio expertise that leads the way to great sound Active 2-way crossovers In professional audio products, an active crossover is used to split the frequencies in a sound signal, with the higher frequencies going to the tweeter amplifier and then to the tweeter, and the lower frequencies going to the woofer amplifier and then to the woofer. In this way, interference between the signals sent to different drivers is avoided. The FIIO SP3 Series uses an active crossover with a crossover frequency of 3.4 kHz, specifically selected to maximise the performance of the tweeter and woofer. The SP3 Series utilises a second order active 2-way filter circuit to more accurately control the crossover frequency and ensure that the signals sent to each driver are more effectively isolated, resulting in less intermodulation distortion, avoiding driver overload and significantly improving the efficiency of the power delivered. The SP3 Series power supplies can deliver up to an astonishing 100W, giving you a truly thunderous sound experience that is unrivalled in its class. Turn it up, turn it up! One of the most important parts of an active desktop speaker is the amplification. The SP3 series is equipped with two Texas Instruments (TI) 3118 Class D amplifiers, which are highly efficient, have a low noise floor and ensure the purity of the audio signal. FIIO's experienced research and development team has developed an active 4-channel crossover system for the SP3 Series, so that each driver has its own independent circuitry for less interference and greater efficiency in converting signals into sound. A robust power supply is all that is needed to realise the full potential of the high-end SP3 Series components. The R&D team spared no expense and equipped the SP3 series with two large Nichicon capacitors with a capacity of 4700uf each. These capacitors contribute to a more stable and cleaner power supply by helping to minimise ripple in the amplifier supply. Sound and size Tiny volume of 2.35 litres to free up space on your desk, the SP3 series has been designed to fit all the necessary components in the smallest possible housing - resulting in a total volume of just 2.35 litres. The SP3 series gives you the flexibility to create a comfortable desktop setup with plenty of space. Die-cast liquid metal housing The SP3 series has a housing made of high-strength die-cast aluminium. The inner walls of the housing are carefully and evenly manufactured to reduce resonances and thus improve the sound quality. The horizontal strips on the front of the speaker serve to stiffen the cabinet and help to avoid unwanted strong vibrations at high volumes. Exclusive stand with 7 degree tilt For an optimal listening experience, the axis of the tweeter should not be more than 15 degrees away from the ear. The SP3 series comes with stands that are raised by 7° to bring the speakers into this perfect position. In addition, the feet of the SP3 series are made of rubber, which prevents a hard connection between the speaker and the table top and acts as a shock absorber. Find out the status of the speakers at a glance To make it easier to recognise what the speakers are currently doing, the development team has set up an RGB lighting system that clearly displays the current status of the speakers. There are also various RGB lighting effects that you can customise to further enhance the listening experience. Closer to your ear and your heart Exclusive stand with 7-degree elevation As usual in the professional audio world and to ensure a better listening experience in the near field, the tweeter should be at ear level and the tweeter axis should not be more than 15 degrees away from the ear. "Therefore, we have developed an exclusive stand with a 7-degree tilt angle especially for the SP3 series. We conducted listening tests with 5-15° and 7-15° stands with the listener 1 to 1.2 metres away from the speaker. In these tests, we concluded that a stand with a 7-degree tilt angle provides the most accurate sound for near-field listeners. In addition, the stand is made of silicone, which acts as a shock absorber by creating a soft surface between the SP3 Series and the desk, reducing sound distortion from vibrations when the speaker is producing sound." Allen Chief Expert of FIIO Audio R&D Centre Consistent FIIO quality Standard 8-pin primary and secondary speaker connection cable Standard 3.5mm to RCA input cable FIIO has always adhered to the principle of user-centricity. In discussions with users, we have found that some well-known speaker brands do not include standard speaker connection cables or input cables, requiring users to purchase an additional cable. This resulted in a poor user experience. As a well-known accessory supplier in the Hi-Fi industry, FIIO provides a large number of Hi-Fi users with thoughtful product experiences with solid materials and rich accessories. Based on market feedback, the SP3 series comes standard with a 3.5mm RCA input cable and an 8-pin primary and secondary speaker connection cable, both made of monocrystalline copper and finished with a shielding layer. These cables are plug-and-play ready so that the user can enjoy the professional hi-fi sound of the SP3 series without any worries. Certified Audio The SP3 has been certified by the Japan Audio Association (JAS) and the Consumer Electronics Association (CEA) with Hi-Res Audio, and the SP3 BT is even certified for both Hi-Res and Hi-Res Wireless Audio. You can be sure that the speakers will reproduce your music faithfully and with high fidelity. Technical data: Speaker type: Active Bluetooth desktop speaker with high fidelity Dimensions: Approx. 163x120x132mm (without base) Approx. 170x120x132mm (including 0° flat base) Approx. 182x120x132mm (including 7° angled base) Bluetooth chip: Qualcomm QCC5124 Bluetooth codecs: LDAC/aptX Adaptive/aptX HD/aptX LL/aptX/AAC/SBC Weight: primary speaker weight 1950g, secondary speaker weight 1780g Cabinet material: aluminium alloy Cabinet manufacturing method: liquid die-casting Crossover: 2-way Frequency response: 65Hz-20kHz (±2dB) Speaker impedance: 8Ω Speaker sensitivity: 85dB (1Vrms)@1kHz Output power: 2x30W (woofer)+2x10W (tweeter) Inputs: RCA/AUX/Type-C/COAX/OPT Length of primary and secondary speaker connection cables: Approximately 2.5m RGB status lights: LDAC: Pulsating white light aptX Adaptive: Pulsating green light aptX HD: Pulsating yellow light aptX/aptX LL: Pulsating purple light AAC: Pulsating cyan light SBC: Pulsating blue light SP3 BT What`s in the box: 1x primary speaker 1x secondary speaker Mains adapter AC mains cable RCA (RCA) to 3.5mm audio cable Connection cable for primary and secondary speakers 2.5 m long 2x pairs of rubber feet (0° and 7°) Instructions for use

Topping U90 USB Bridge - What actually is a USB Bridge and what do I need it for?The main idea behind converting the original digital USB signal into an alternative digital signal is to pre-filter the digital data. This is achieved in the Topping USB Bridge by using a femtoclock oscillator. The optimisation of the digital signal achieves an incredible jitter reduction (see picture description).In addition to the optimisation of the digital signal, the distance to be bridged plays a major role. With conventional USB cables, the data rate to be transmitted decreases after only a few metres. With optical cables, distances of up to 30 metres can be bridged without loss of speed. With USB cables, the data rate for high-resolution data material stops after only a few metres.USB isolationThe USB isolation of the USB connector separates the Topping U90 consequently from the power supply of the computer. Due to multiple circuits and many connected devices, computers have a ground problem that has a negative acoustic effect. The USB Isolator "isolates" this problem.12V TriggerThe Topping U90 has a 12V trigger output. In combination with another device that supports this function, the devices connected in series can be switched "on" and "off" in parallel.IIS compatibilityThe U90 comes with four different pre-configured setups that support different IIS pin settings. For details, please refer to the image description.Supported resolutionsThe Topping USB Bridge supports the following resolutions: Up to PCM 32Bit/768kHz and DSD512 native
