ATI Amplifier Technologies - AT 3000 Series - Multi-Channel Stereo Amplifier 

Featuring true differential design, this series represents ATI's “Pure Balance”® technology balanced from input to output. The design allows the quietest and purest reproduction of the audio signal. The AT3000 series amps are available in 2 to 7 channel configurations. Each model in the series comes standard with 2 massive toroidal transformers and can be upgraded at the factory by changing power transformers, adding power modules and a new rear panel. The maximum is 7 channels. A common ground all home theater enthusiasts can find is that the best possible design is the fully differential balanced amplifier.

A fully differential amplifier is basically two separate amplification circuits per channel. One channel is inverted at the input and the output of each is summed allowing the speakers to be driven by a push/pull action; because of this, it automatically rejects any noise coming from external sources, eliminates hum and reduces distortion. For better reproduction of high frequencies and transient performance the slew rate of the amplifier is doubled. This technology is called Pure Balance®, and is used in both the AT3000 and the AT2000 series; the result is breathtaking. ATI’s Pure Balance® amplifiers keep the signal balanced all the way from the XLR inputs to the speaker outputs.

ATI Amplifier Technologies - AT 3000 Series

FEATURES:

Remote Trigger
       Activated from 3.3VDC to 24 VDC via a heavy-duty relay

Protection Circuits
       Optically - coupled with full automatic reset.

Toroid Transformers
       40% more efficient than EI type. Separate bi-filar windings for each channel guaranty lower noise and crosstalk.

Circuit Boards
        Double-sided, FR-4 glass-epoxy, computer-grade boards are assembled in-house.

Soft Start Circuitry
        Ultra soft turn on reduces in-rush current to a minimum. Multiple units can be turned on without tripping circuit breakers eliminating the need for sequencing.

Power Transistors 
        High-current, bi-polar output transistors with active bias circuits result in effortless operation.

Power Cord
        Detachable, 3-wire cord.

7-Year Warranty
        Parts and labor against defects in parts or workmanship.
