ZEN One Signature

Our ZEN One Signature adopts the DAC level idea of ZEN DAC V2, adds S/PDIF input optical fiber and coaxial beside the USB interface, and adds the Bluetooth technology inherited from ZEN Blue V2 to it, and adds a Signature level circuit in the pot Improvements create a delicious audio mix美味的音訊混合物。

What the result is, the ZEN One Signature is a pure DAC with no built-in headphone amplifier and volume control. It acts as the hub of the home audio system for all digital devices, from smartphones and tablets to PCs and Macs, from CD players and music servers to TVs. and game consoles電視和遊戲機。

Home System Hub

DAC ZEN One Signature is the first ZEN DAC to support all high resolutions。

DSD256PCM384MQA384kHz Bluetooth 96KHz 96kHz High Resolution Bluetooth LDAC, HWA/LHDC, aptX Adaptive/HD/LL, AAC Amplifier has no volume control大器,沒有音量控制。

The ultimate DAC for all your home audio sources。

High resolution bluetooth

Next-generation high-resolution Bluetooth technology in ZEN One Signature ensures the best possible sound for every source Supports a wide range of high-resolution codecs aptX HDaptX Adaptive LDAC and HWA/LHDCLHDC。

High gain antenna provides extended bluetooth range you'll love it的。

Sharp and discriminating digital specifications格

  • ZEN One Signature offers the following to transform home music enjoyment。
  • True native high-resolution DAC supports 32-bit/384kHz PCM and fully native DSD Powerful 16-core XMOS processor performs full MQA decoding to 384kHzkHz)。
  • Upgraded GMT femtosecond clock and custom digital filter eliminate jitter and other forms of digital distortion。
  • Optical and coaxial S/PDIF digital outputs support 32-bit/192kHz PCM and MQA

awesome analog design

Balanced circuit is a famous feature of the ZEN series。

  • ZEN One Signature continues this traditional balanced circuit design with Signature-grade circuit components providing ultra-low distortion and exceptional sonic purity度。
  • 4.4mm balanced and RCA single-ended analog output Connect to integrated amplifier pre-amplifier headphone amplifier or active speakers式喇叭

Signature Special

The Signature range always includes additional special additions。

  • Low jitter Feitou clock crystal provides >20dB performance
  • 16-core 2000MIPS XMOS low-latency microcontroller 4x the processing power力
  • C0G capacitors have high linearity and excellent temperature/frequency characteristics特性
  • MELF resistors with high precision and low noise噪音
  • Taiyo Yuden and Murata inductors Low impedance power rails軌
  • High gain antenna for extended range圍

We used Qualcomm's new QCC5100 Bluetooth processing chip combined with proprietary circuitry to create a great-sounding Bluetooth engine引擎”。

Supports all current high-resolution Bluetooth audio formats Qualcomm's aptX Adaptive and aptX HD Sony's LDAC and HWA LHDC regular aptX and aptX Low Latency AAC Apple iOS devices and SBC regular Bluetooth codecs通 “藍牙編解碼器)。

In 24-bit codecs aptX Adaptive and aptX HD support up to 48kHz and LDAC and LHDC up to 96kHz iFi's bluetooth engine can also be updated live online so future codecs may be added可能會被添加。

The Burr-Brown True Native chipset means the file format remains the same or a perfect bit rate which means you're listening to music in the format it was recorded in as the artist intended的格式進行的。

At iFi we use Burr Brown extensively in our products because of its natural hearing musicality and True Native architecture Our experience with this IC means we know how to get the most out of it度地利用它。

MQA (Master Quality Authenticated)

MQA is an award-winning British technology that delivers the sound of original master recordings音。

MQA master files are fully certified and small enough for streaming or download ZEN One Signature uses MQA technology to receive and decode MQA audio for masterful sound級的聲音。


This is a method superior to traditional single-ended circuit methods. Balanced circuits reduce noise and crosstalk.擾。

Clearer sound with fewer distractions聲音。

You would normally find this setup in higher price ranges like the Pro iCAN but iFi is now using this setup across its entire range to provide the highest quality audio to all of our customers質的音頻。

Extensive jitter removal technologies are applied to the digital stage including our GMT global master timing femtosecond accurate clock and smart memory buffers緩衝器。

Low jitter crystal clock has been updated to provide >20dB better performance能。

Panasonic OS-CON capacitors have a total capacity of 5,410uF with extremely low equivalent series resistance ESR Excellent noise reduction capability and frequency response characteristics響應特性。

In addition OS-CONs have a long lifespan as the electrolyte is solid and their ESR does not change much even at low temperatures They are not common in products priced < $1000們並不常見。

Texas Instruments Low Noise ICs Offer Excellent Unity Gain Bandwidth Very Low Noise and Distortion High Output Drive Capability Over 100 dB Common Mode and Power Supply Rejection Ratio Wide Maximum Output Swing Bandwidth and High Slew Rate高轉換率。

muRata Controlled Low ESR High Q Multilayer Capacitors Murata is special in ESR control and their noise suppression capability is impressive人印象深刻。

We use ELNA Japan Silmic II capacitors as power supply。

The main component of the newly developed dielectric is silk fibers, a material thought to be as unfathomable as aluminum electrolytic capacitors測。

The new material beats silk fibers and mixes them with Manila hemp fibers. Aluminum electrolytic capacitors used for advanced music use provide the dielectric. The result is second-to-none superior acoustic properties and excellent linearity.的線性。

Vishay MELF resistors are complex and expensive but offer superior performance能優越。

These metal electrode leadless surface resistors have excellent accuracy, stability, reliability and pulse load capability. They offer the best power rating and pulse load capability.載能力。

They show the lowest noise and distortion of any available resistor on the market。

TDK C0G1 Class Ceramic Capacitors Offer High Stability and Low Loss for Resonant Circuit Applications損耗。

These capacitors are getting closer and closer to the theoretical ideal of pure frequency constant capacitance, reducing capacitor-induced distortion to a level that is virtually non-existent平。

They are expensive but the perfect complement to our products充。
