The Model 2125 is a Class AB amplifier designed for efficient, low heat operation. Its fully discrete circuitry is powered by a huge toroid transformer, and is capable of delivering 35 amps peak current per channel. It features a switchable 20 Hz or 40 Hz, 18 dB/octave high pass filter that can be activated to minimize wasted bass energy when driving multiple small speakers or to defeat the negative impedance effects of auto-former wall-mounted volume controls. There is also a impedance selector switch for very low impedance speaker chains.

For integration with processing and control equipment, it features both a DC trigger input with looping output and adjustable sensitivity audio signal sensing for automatic on/off control. A ground lift switch is included on the rear panel, as are gold plated RCA inputs, and A/B speaker terminals with individual on-off and heavy-duty 24 K gold plated five-way speaker terminals for each channel. The Model 2125 includes DC Servo and relay protection circuits, and there are front panel indicators for high temperature, standby, and status of each channel.
