Heathkit AA-1600 power amplifier

High-Performance Rack-Mount Stereo Power Amplifier

The AA-1600 is the first amplifier in our new series of professional-style rack-mount stereo components. Other products in the series include the AD-1701 Graphic Indicator, the AJ-1600 AM/FM Digital Tuner, and the AP-a800 Deluxe Stereo Preamplifier. In performance, specifications and sound reproduction, these products are designed to rank with the finest stereo components available anywhere.

The AA-1600 reproduces the entire musical spectrum with a clarity and definition that make it an excellent choice for use with the most demanding speaker systems. Hhum and noise are a full 100 dB down, so music springs forth from a background of total silence. Transient Intermodulation Distortion, a recently discovered form of amplifier distortion which tends to "muddy" the sound, is so low (less than 0,05%) we're one of the few manufacturers to specify it. This low T.I.M. contributes to clean, well-defined sound especially at the high end of the frequency spectrum. Fused B+ and B- power supply lines for each channel, along with especially rugged output devices, eliminate the need for dissipation limiters which can cause tweeter-damaging clicks and pops from faalse triggering.

Of course, there's complete speaker and circuit protection, including speaker turn-on delay and a thermal circuit breaker.

To assure performance to our superior specifications, the amplifier and power supply circuit boards are supplied fully assembled, tested and adjusted. Minimal point-to-point wiring and a clean, opem chassis layout contribute to easy building. The AA-1600 is designed for mounting in a standard EIA equipment rack, or for installation in the AEA-1800-1 accessory cabinet. The AA-1600 is one of the finest amplifiers Heath has ever designed, and an easy and enjoyable kitbuilding experience too. Make it a part of your music system now.
