Modern mixer equipped into DSP signaling processor which allows precise correction of sound characteristic in buildings with very difficult acoustic conditions. Mixer activates only those microphones that are being used at the moment, which eliminates the influence of the surrounding sounds coming from unnecessarly opened microphone channels (one of the programming option).
Equipment of a digital mixer with DSP processor:
- 16 programmable or linear symmetrical microphone inputs (XLR socket) with sensitivity control, gain control, high and low tones control and controling level indicator ;
- in each microphone channel there is: 100Hz filter turned on, microphone/line changeover and Phantom power supply;
- automatic echo elimination;
- universal RCA (Cinch) input with gain control and with soprano and bass control ;
- 10-point parametric input equalizer:
– frequency control from 20 Hz to 20 kHz,
– width band control from 0,05 to 3 dB/oct.
– depth band control from -12dB to +12dB - 4 symmetrical output 0dB (4x 2XLR):
– gain control
– delay line control (from 0 to 170m),
– 5-point parametric equlizer ( frequency control from 20 Hz to 20kHz), width band control from 0,05 to 3 dB/oct. depth band control from -12dB to +12dB; - acoustic feedback suppressor turned on;
- 2 symmetrical output 0 db to subwoofer ;
- 2 symmetrical output to record ;
- to build in to rack 19’’ type cabinet;
