Amplifier Technologies, Inc (ATI) AT4000 Signature Amplifiers

 

  Amplifier Technologies, Inc. (ATI), the prolific manufacturer of many of the high end audio's best amplifiers today announced that the AT4000 Series Amplifiers can be seen at the Venetian Hotel suite 29-332 during CES 2016. Available with 2 to 7 channels the 4000 Series uses the same fully balanced design with current feedback and dual DC-Servos as ATI's award-winning 6000 series amplifiers. Guaranteed minimum output is 200W RMS per channel at 8 Ohms with 300W RMS at 4 Ohms; all channels driven. Guided by legendary amplifier designer Morris Kessler, ATI offers both performance and value in audio components.

 

The new At400 series features:

1. Fully balanced, differential amplifier design with two output stages per channel but with only a single input stage. The advantages of balanced designs are retained and noise is further reduced by 50%.

2. Current feedback instead of the more common voltage feedback. The reason: current feedback amplifiers are faster with virtually unlimited slew rate and are better able to reproduce today's best music and film.

3. Thermaltrak output devices: Unlike traditional designs where external diodes attached to the heat sink track the amplifiers operating conditions to adjust bias, Thermaltrak devices have the diodes in the same package as the transistors so bias is optimized in real-time.

4. Dual DC servos per channel to control DC offset.

5. Dual toroidal transformers with independent secondary windings. Electrically, each amplifier channel has its own transformer.

 

All the amplifiers in the 4000 series are rated at 200 Watts RMS from 20 Hz to 20 kHz with no more that 0.03% THD at 8 Ohms with all channels driven and 300 Watts RMS at 4 ohms under the same conditions. Signal-to-noise ratio is typically 126dB referenced to full output so each amplifier in the series is capable of playing back the full dynamic range available on today's lossless recordings.

 

AT4002 Stereo Signature Amplifier $2,995
AT4003 3-channel Signature Amplifier $3,595
AT4004 4-channel Signature Amplifier $4,195
AT4005 5-channel Signature Amplifier $4,795
AT4006 6-channel Signature Amplifier $5,395
AT4007 7-channel Signature Amplifier $5,995

 

All ATI amplifiers are available in standard (17") and rack-mount (19") chassis with domestic (117V) of Export (220 to 240V) chassis and are covered by ATI's 7-year transferable warranty.
