SR-1604 -Auxiliary equipment Audio processors

Feedback suppressor

This feedback suppressor features a feedback detection and suppression algorithm based on dynamic scanning of frequency bands. It analyses the audio signal and detects the frequencies causing the feedback. It eliminates feedback by adjusting the parameters of up to 12 high-precision adaptive notch filters per channel. The filters provide an attenuation of up to 45 dB.
The sensitivity of the feedback detection system can be selected in 15 levels to best suit the scenario. Features 20 built-in preset memories (4 factory presets and 16 user presets) for use in different configurations.
Excellent audio performance, high quality DSP, A/D D/A 24-bit converters and 48 kHz sampling rate. Extremely low noise and distortion.
Balanced XLR inputs and outputs and 6.3 mm jack for easy connection.
LCD information display and MIDI control possibility.
Stereo or mono operation.

Perfect for venues with high reverberation and likelihood of feedback due to room materials or loudspeakers placed close to the microphones, e.g. assembly halls, religious buildings, conference rooms, etc.
