Description

The Teac AI-301DA Intergrated Amplifier with USB Streaming signals the beginning of a new chapter for TEAC, with both high-resolution audio and Bluetooth playback in a single-box product.

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.

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.

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.

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.

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 60W + 60W (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.

Key Features:

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.

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.

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.
