Audiophony PA - AMP1100

The AMP1100 is a single-channel, 1100 W power amplifier for 70/100 V lines, designed for medium-sized distributed sound systems. It is the ideal solution for all single-zone installations requiring high power, reliability, and simple, stable management of the constant voltage line.

Class-D technology ensures stable power delivery with a low thermal footprint, maintaining distortion below 0.1% and a signal-to-noise ratio above 100 dB. Thermoregulated ventilation ensures reliable operation and long life even under prolonged load conditions, automatically adapting fan speed to thermal requirements.

An intelligent standby system automatically reduces power consumption in the absence of a signal, helping to keep operating costs low without compromising responsiveness: the amplifier immediately returns to full power as soon as an incoming audio signal is detected.

The configuration is designed for installers: each channel features volume control and a selectable high-pass filter (HPF), both accessible from the rear panel. Euroblock terminals simplify wiring, while dedicated front LEDs (SIGNAL, –20 dB, CLIP, PROTECT) provide instant visual control of system status.

The entire system is housed in a rugged 2U chassis with a standard 19" rack mount, weighing just 7.8 kg.
