IFI ZEN ONE SIGNATURE DAC RELEASED
British audio brand iFi expands its ZEN Signature range with the iFi ZEN One Signature.

Home Hub DAC
The ZEN One Signature is the first ZEN DAC to support all hi-res: DSD256, PCM384, MQA384kHz, Bluetooth 96KHz.
96kHz Hi-Res Bluetooth: LDAC, HWA/LHDC, aptX Adaptive/HD/LL, AAC

USB audio using 16 Core 2000MIPS XMOS low latency microcontroller (MQA decoder)
Fully balanced 4.4mm output
Purity of design, no headphone amp, no volume control. The ultimate DAC for all your home audio sources.

Described as a ‘universal DAC’ owing to its many input options, the iFi ZEN One Signature takes the DAC stage from the ZEN DAC V2, adds S/PDIF inputs (optical and coaxial) alongside the USB port, Bluetooth technology from the ZEN Blue V2 and finishes it off with Signature-grade circuit enhancements.

iFi says: be at One with your sound
One DAC with universal connectivity – iFi’s ZEN One Signature delivers
exceptional sound from every digital device in a home audio environment

DAC’s The Way To Do It
The ZEN One Signature’s ‘digital engine’ is based around a Burr-Brown DAC chipset that iFi uses extensively, selected for its natural-sounding ‘musicality’ and True Native architecture. iFi’s experience with this IC means it knows how to make the most of it; but whilst intrinsic to the resulting sound, the creation of an exemplary DAC stage involves much more than the selection of a particular DAC chip.

One such critical component is the XMOS chip that processes the audio data received via the USB and S/PDIF digital inputs. The ZEN One Signature uses a low-latency, 16-core XMOS microcontroller delivering enhanced processing power; iFi’s in-house digital development team has programmed the XMOS firmware to optimise sound quality and ensure a perfect partnership with the Burr-Brown DAC. Extensive jitter-eradication technologies are also applied to the digital stage, including the latest generation of iFi’s GMT (Global Master Timing) femto-precision clock and intelligent memory buffer.

The ZEN One Signature’s hi-res audio credentials encompass 32-bit/384kHz PCM over USB (192kHz over S/PDIF), all levels of DSD to DSD256, and single- and double-speed DXD. Thanks to the Burr-Brown DAC chip’s four-channel True Native design, PCM and DSD take separate pathways – this enables DSD, as well as PCM, to remain ‘bit-perfect’ in its native form right through to analogue conversion.

MQA – the hi-res streaming format – is also supported, with full decoding of MQA files up to 384kHz. This means that the complete ‘three unfold’ decoding process is performed internally, as opposed to just the final unfold in the manner of an MQA ‘renderer’ – ideal for subscribers to Tidal’s ‘HiFi Plus’ tier, where Tidal Masters (MQA) content can be found.

ZEN One Signature：LDAC、aptX HD、MQA 通殺　純數碼結合藍牙接收

ZEN One Signature，內置藍牙接收功能，支援 aptX HD、LDAC、LHDC 等最高編碼規格，為聲音系統提供純聲音解碼選擇.  ZEN One Signature 的定位比較特別，可說是將 ZEN DAC V2 及 ZEN Blue V2 的精華融合一起。作為一部 Signature 級產品，機內的設計盡量簡化，以減少音染。One Signature 與 DAC V2 不同之處，是不設耳擴及音量控制，對於連接主動式喇叭或者另駁前級的用家來說，One Signature 就最適合使用了，加上愈來愈多人使用 DAP 或電話作為訊源，以 Wi-Fi 或藍牙連接音響系統十分普遍，提供高質素的藍牙連接是變得重要，One Signature 內置 Qualcomm 最新 QCC5100 藍牙接收晶片，支援市場上最高規格編碼標準，包括 aptX HD、LDAC、LHDC 等，亦支援傳統 AAC 及 SBC 編碼，機背更設有天線加強接收表現。

與 ZEN DAC V2 一樣，ZEN One Signature 支援最高 32-bit/384kHz PCM 及 DSD 原生解碼，採用 16 核心，具 2000MIPS 運算能力的 XMOS 處理器，提供高達 384kHz MQA 全解碼功能，同軸、光纖輸出則支援最高 32-bit/192kHz PCM 及 MQA 。採用 Burr-Brown True Native 解碼晶片，輸出更有自然、有音樂味的音色。此外，ZEN One Signature 亦採用不少發燒級元件，包括在不同線路部分採用 ELNA、Panasonic OS-CON、TDK 與 muRata 電容、Vishay MELF 電阻、飛秒時鐘等等。

面板上設有兩個指示燈，較大的 iFi 顯示燈以顏色顯示輸入格式，右邊較細的顯示燈則是顯示不同的取様頻率。iFi 顯示燈除了顯示輸入格式屬 PCM、DSD 還是 MQA 外，亦可詳細顯示包括 LHDC、LDAC、aptX Adaptive、aptX HD、aptX、AAC 與 SBC 藍牙編碼格式。至於右邊顯示燈，則用於顯示 PCM 44.1kHz/48kHz、PCM 88.1kHz - 384kHz、DSD 64/128 與 DSD 256 音樂規格。

雖然 ZEN One Signature 不設耳擴，但機身設有 4.4mm 平衡輸出，機內設有兩組獨立平衡音訊放大線路，輸出電壓較 RCA Audio 音訊輸出高一倍，使用 4.4mm 平衡輸出的原因，相信是機身已無法放置 XLR 接口而已，假如是使用具備平衡輸入的耳擴或前級，可配合 4.4mm 接線或 4.4mm → XLR 轉換線。

在音響系統上加入藍牙連接，除了換部具備藍牙功能的串流播放器，亦可增添一部藍牙接收器。iFi 推出 ZEN One Signature ，就是將藍牙功能結合在解碼器上，以簡約及更 High End 的方式增添藍牙連接功能，最重要是售價與其他 iFi 產品一樣親民，不需 $3,000 便能入手，想更換純解碼兼備藍牙連接的朋友，One Signature 是相當值得考慮的選擇。
