no shortcuts, no compromises

Wiring

Open most multi-channel power amplifiers and you will see a “rat ’s nest ”—dozens of wires running haphazardly through the chassis. Open up an SAE amplifier, though, and you will see a clean layout, with wires wrapped neatly in a fiberglass cloth tubing originally developed for the aerospace industry. The tubing protects the wire from both heat and accidental damage.

Chassis-Mounted RCA Jacks

The gold-plated RCA input jacks on our amplifiers are mounted directly to the rear panel, instead of to a circuit board. While this technique complicates assembly, it results in a more robust connection, and the jack cannot be accidentally broken off by the tight-gripping RCA plugs used on many audiophile interconnect cables. In addition, our AT2000 and AT3000 Series power amplifiers use XLR-type connectors to make connections with the balanced audio output from a preamplifier such as our ATP8500.1 with balanced audio outputs.

Trouble-Free Circuit Breakers

Our higher power multi-channel amplifiers use magnetic circuit breakers to protect against AC overloads. If the breaker trips, it ’s a simple matter to reset it. Most amplifiers, however, use fuses for overload protection; if a fuse blows, you must have the proper one available to restore power to your amplifier.

Protection Circuits

SAE amplifiers employ lightning-fast optically-coupled protection circuits that are completely removed from the signal path so they cannot affect the sound quality. These protection circuits are designed to detect electrical “shorts ” in speakers or speaker wires and to sense electrical “spikes.” If triggered, the circuit will disengage the output. The protection circuit will sample the affected circuit every 10 seconds and will restore output automatically when safe to do so. This special feature minimizes the chance of your amplifier going out of service just when you ’ve filled your home theatre with expectant guests.
