 Product overview

The AI-301DA-X is a successor to the AI-301DA, offering a newly refined audio performance tuned in
Europe.

In order to update the sound quality to meet today’s requirement for Hi-Res sound, our engineers
have carried out an exhaustive development programme, using selected parts ranges exclusively
specified for hi-fi applications.

Supporting DSD128 and PCM192/32 input from PC/Mac, an improved analogue audio circuit delivers
excellent sound quality, while a built-in Bluetooth® receiver supports the Qualcomm™ aptX® codec,
allowing you to enjoy high quality wireless audio streaming from a PC or tablet.

In addition, the AI-310DA-X’s subwoofer pre-out and auto-power on/off functions allow you to create
a compact 2.1ch home theater system which can be set to automatically power up when your TV set
is turned on.

Rich and engaging sound quality, refined in Europe

 Tuned in Europe

The previous AI-301DA sounded excellent but our engineers have gone even further with AI-301DA­X, listening, tuning and refining the audio quality over an extended period of time, the final tuning
being carried out in Europe. The results of those efforts can be heard in the rich, musical character
and considerable dynamic ability of this latest version.

 High performance power amplifier from ICEpower

The beating heart of the AI-301DA-X is a high performance, energy efficient power amplifier module
from ICEpower of Denmark. Thanks to its intelligent energy management technology, the AI-301DA­X can deliver as much as 60W + 60W of output power.

 Robust aluminum body and small footprint

A sleek and compact body with a small footprint (215mm width, 254mm depth and 61mm height)
allows you to place the AI-301DA-X in very small spaces, such as in a tiny gap in a TV stand or on a
desktop. A beautifully machined aluminum volume knob and panels give it an innate feeling of
elegance, while full-metal body construction achieves excellent vibration suppression, to minimise any
adverse effects on sound quality.

 Built-in Bluetooth® receiver for wireless streaming

The AI-301DA-X features a built-in Bluetooth® receiver module supporting the Qualcomm™ aptX®
codec for high quality wireless audio streaming. Qualcomm™ aptX® achieves low-latency and
excellent error recovery, resulting in superb sound, qualities which have made this codec an industry­standard for wireless streaming. And, for the benefit of those streaming from an iPhone/iPad, the
high-performance AAC codec is also supported.

 Automatically powers up on detecting a digital signal

The AI-301DA-X automatically turns on when an incoming digital audio signal is detected, and
automatically turns off when the signal is switched off. This allows you to, for instance, switch on the

AI-301DA-X merely by powering up your TV set, ensuring you can enjoy enhanced TV audio with the
minimum of fuss.

 32-bit BurrBrown PCM1795 D/A converter

In order to process the huge amounts of digital audio data present in DSD128
and PCM 192kHz/32 content, a high-performance BurrBrown PCM 1795 D/A
converter is employed. Its 32-bit processing conveys fine detail and a depth of
sound from Hi-Res files that’s far beyond what you can hear from standard
audio CD.

 Supports DSD128 native playback

The AI-301DA-X is equipped with a USB port supporting DSD Native
playback. This directly converts DSD signal into an analogue waveform
in ASIO2.1 and DoP formats, without changing the PCM format. In
addition, asynchronous transfer mode is also supported for accurate
data transfer by referencing the more accurate on-board clock of the
AI-301DA-X. Furthermore, a free TEAC HR Audio Player allows users
to play back, Hi-Res files such as DSD128 and PCM192/32 from
Windows/Mac without the need for complicated configuration.

 High quality 100mW + 100mW headphone output stage

The AI-301DA-X integrates TEAC’s CCLC (Coupling Capacitor-less Circuit) into its onboard headphone
amplifier, an innovation that that delivers rich bass sound and quick transient response, by
eliminating capacitors in the output stage, while delivering 100mW + 100mW of output power
(32ohm load).

 Conventional coaxial and optical digital inputs

In addition to a USB audio input, conventional S/PDIF inputs are also provided, the coaxial digital
input supporting signals up to 192kHz/24-bit while the optical supports up to 96kHz/24-bit.

 Subwoofer pre-out for 2.1 system

A subwoofer pre-out on the AI-301DA-X allows you to connect a powered subwoofer for extra bass
sound in a 2.1ch system, especially useful for TV sound enhancement.
