■ Compact, with USB input and fully compatible with high-resolution DSD
 Capable of 5.6MHz DSD native playback
The USB input facility allows DSD native playback which converts 5.6MHz DSD
files directly into analog signals without needing first to convert it to PCM. It
supports both the ASIO2.1 and DoP (DSD over PCM) conversion methods. Using
the AI-301DA in conjunction with the TEAC HR Audio Player* high-resolution
playback computer software application, anyone can easily explore the world of
high-rez digital audio, including 5.6MHz DSD or 32bit/192 kHz PCM files, without
struggling to have to understand complex settings etc.
* TEAC HR Audio Player can be downloaded for free from the TEAC website.
 Asynchronous mode-capable USB input
When receiving digital audio signals from a computer via USB cable, the unit can
operate in asynchronous mode, controlling the timing of the input signal using
the UD-301's internal clock (which is identical to the one used in the UD-501).
With asynchronous transmission over USB, signal compromising jitter is
effectively eliminated, allowing digital audio signals to be transmitted in a pure,
unadulterated state.
 Coaxial and optical digital inputs offer versatility
Besides its a USB audio input, the AI-301DA is also fitted with S/PDIF inputs for
maximum compatibility. The coaxial digital input supports up to 24bit/192kHz while the optical digital input
supports up to 24bit/96kHz digital audio.
 Wireless playback at high sound quality via Bluetooth® using the aptX® codec
The AI-301DA supports the aptX® codec which offers high sound quality wireless
playback capability via Bluetooth® hardware. Besides high quality sound, the aptX®
codec also offers low latency and an excellent error recovery function, both crucial
features for achieving the best audio performance.
 High-performance BurrBrown PCM1795 digital-analog converter
The BurrBrown PCM 1795 D/A converter converts 5.6MKz DSD or 32bit/192kHz PCM digital data into analog form.
The analog signal, which is derived from huge digital audio data files (far larger than those used by CD) delivers a
finely etched sound, with a great sense of depth.
 ICEpower high sound quality Class-D amp circuit
The power amplifier stage is based upon a tried and tested Class-D amp, manufactured by ICEpower of Denmark.
It converts a high-resolution sound source into high-definition speaker signals using a
feedback loop between a hybrid feedback controlled oscillating modulator (HCOM)
which faithfully amplifies the signal, and a multivariable enhanced cascade control
(MECC). The efficient design of the 40W + 40W (4 ohms) amplifier creates very little
heat, eliminating any need for a cooling fan, thus affording a quiet environment that's
ideal for musical appreciation.
 CCLC circuits provide high-quality headphone output
The 100mW + 100mW output (at 32 ohms load) headphone amplifier uses CCLC (Coupling Capacitor Less Circuit)
technology. In ordinary headphone output circuits, a capacitor is used for output-stage coupling, and so the sound

is unavoidably colored. When the capacitor is combined with a high-pass filter this often results in phase lags, or
low frequency level degradation. With CCLC the negative impact of capacitors on sound quality is eliminated,
providing full low-frequency sound and a responsive headphone listening environment with great spatiality.
 Well-engineered aluminum enclosure, compact proportions
Following on from our development of the 501 series concept (small high-performance
audio components that can be fitted on a desktop) we decided, at the outset, that the
301 series would be an even more compact design. Now, the casework has been
shrunken to just 215mm wide, allowing greater freedom in positioning the amplifier.
External highlights include aluminum panels and a motor-driven volume knob with the
tactile feel you'd expect from controls found in high end full-size hi-fi components. At
the same time, the solid enclosure underpinned by the metal chassis, is impressively
inert, minimizing the effects of vibration on the unit's sound quality.
 Simple operation with Auto Power On
The AI-301DA has a well-conceived Auto Power On function which automatically switches on the unit's power when
it senses a digital signal input. When the amplifier is connected to optical digital audio output from a television set,
just switching on the television turns on the power of the AI-301DA, enabling you to immediately enjoy high-quality
sound without having to adjust any other settings. This facility makes life very convenient allowing users to switch
on the TV and instantly listen to music or a soundtrack.
 Combine with the LS-301 speakers to create a simple high-resolution system
Combining the AI301-DA, with its high-performance engineering packed into a compact body, and the LS-301
coaxial speaker, specifically developed to match it, creates a system that does full justice to any high-resolution
audio source.
What's more, the AI301-DA has been fitted with a sub-woofer pre-out plug so that the user can, if they wish, also
employ the equally compact 2.1ch LS-WH01 satellite/subwoofer system, ,making for an extraordinarily compact
2.1ch system that can easily be placed on a desktop or next to a TV set.
