AMWLC-9DSP4D
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. The amplifier is equipped with an MP3 player with remote control, liturgical clock that switches presets according to pre-defined dates and times and in the “DE-ESSER” which eliminates sibilance during speech. Amplifier in AMWL-9DSP/400+100 version has got extra 100W power amplifier.
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;
- 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;
- 10-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; - 4 symmetrical outputs 0 dB (1 x Jack + 3 x XLR):
– Gain- control
– Delay (from 0 to 85m),
– 5-point 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);
- DE-ESSER
- MP3-Player USB SD
- 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
