The Model 2250 is a Class AB amplifier designed for efficient, low heat operation. Its fully discrete
circuitry is powered by an enormous toroid transformer, and is capable of delivering 45 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 speaker pairs and to negate the reactive load
impact of popular 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 fea-
tures 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 2250 includes DC Servo and relay protection circuits, and there are front panel indica-
tors for high temperature, standby, and status of each channel. It occupies three rack spaces when
mounted with the optional RMK33 rack-mount kit.
