Description stereo amplifier, TEAC AI-301DA

In compact metal housing TEAC AI-301DA concluded integrated stereo amplifier rated power of 2 x 43 W, modern digital-to-analog Converter and receiver Bluetooth aptX enhanced audio codec. On the uncluttered front panel, made of aluminium, are only volume control and source selector with led indication, as well as a 6.3 mm Jack for connecting stereotipov. The device differs high quality of manufacturing and finish, comes in black or silver colors.

The DAC in the amplifier is made based on BurrBrown PCM1795 chip with a USB input (B-type), as well as optical and coaxial inputs. Receiver USB interface works in asynchronous mode and this input the TEAC AI-301DA can accept a digital PCM stream with options up to 32 bit/192 kHz and DSD 2.8 / 5.6 MHz in the mode of the DoP. Also, the device has two line analog inputs and Bluetooth (aptX) to receive a signal from compatible portable devices. The amplifier is manufactured using high quality components in all important from the point of view of the quality of the sound areas of the circuit, and is equipped with a custom-made variable resistor with the electric drive to adjust the volume.

In the TEAC AI-301DA has a separate headphone amplifier, made by the scheme with a reduced number of dividing capacitors (CCLC). Amplifier cascades for the acoustic systems operate in D-class and are based on ICEpower. With output power up to 60 watts per channel (impedance load 4 ohms) amplifier almost does not radiate heat and is very energy efficient power supply. For connecting speaker cables the unit is equipped with reliable screw terminals.

The amplifier copes with any bookshelf speakers (TEAC recommends the use of firmennye AC LS-301) compact or outdoor, and for increasing returns provides a special subwoofer output. AI-301DA is equipped with a remote control that fits to other models in this series TEAC
