AMWL-DSP1 Type amplifiers

Equipment of Amplifier with DSP processor:

eight XLR programmable, symmetrical microphone or linear inputs with sensitivity, gain, soprano, and bass control, as well as overdrive signalling;

adjustable expander and compressor to be turned on, 100 Hz filter to be turned on, microphone/line changeover and Phantom power supply;

choice of two recorded arrangements (preset for small or big amount of people in a building);

automatic echo elimination;

RCA (Cinch) universal input with gain, soprano and bass control;

15-point equalizer with choice of parametric filter or shalving filter:
- frequency control from 20 Hz to 20 kHz,
- bandwidth control from 0,05 to 3 dB/oct.
- band depth control from -12 dB to +12 dB;
- shalving filter: LoSh6, LoSh12, HiSh6, HiSh12;

symmetrical 0dB XLR output:
- gain control,
- delay line control (from 0 to 170m),

acoustic feedback suppressor turned on;

power terminal protection devices: temperature, anti-short-circuit, current, anti high frequency and limiter;

can be made as a table type or built in a 19” rack cabinet.

A modern amplifier equipped with a DSP signal processor, which enables precise sound properties equalization in buildings with very hard acoustic conditions.
The amplifier activates only those microphones that are being used at the moment, which eliminates the influence of the surrounding sound coming out of unnecessarily opened microphone channels.
