AMWL-7DSP1D
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:
- six XLR programmable, symmetrical microphone or linear inputs with sensitivity, gain, soprano, and bass control, as well as overdrive signalling;
- each microphone channel has a 100Hz filter, switchable mic / line inputs with phantom power;
- choice of two recorded settings (preset for small or big amount of people in a building);
- automatic reverb elimination
- RCA (Cinch) universal input with gain, soprano and bass control;
- 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; - symmetrical 0dB XLR output:
– gain control,
– delay line control (from 0 to 85m), - acoustic feedback suppressor;
- DE-ESSER
- USB/SD MP3 player with a remote control
- 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.
