Automatic digital amplifier AMWL-7DSP1
Highest Quality!
 

 

    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.


Amplifier with DSP processor equipment:
 
punktor

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

punktor

Adjustable expander and compressor to be turned on, 100 Hz filter to be turned on, microphone/line changeover and Phantom power supply in each microphone channel

punktor

Selection of one of the two saved settings

punktor

Automatic echo elimination

punktor

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

punktor

15-point input parametric equalizer:
- 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;
- Choice of Shelving-Filters LoSh6, LoSh12, HiSh6, HiSh12;

punktor

4 symmetrical 0 dB outputs (1 x Jack + 3 x XLR):
- gain control, 
- delay line control (from 0 to 85m),

punktor

acoustic feedback suppressor turned on;

punktor

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

punktor

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