2.- Power supply voltage selector.
3.- OUTPUTS: audio signal outputs. Balanced aux line output signal, XLR and 6.3 mm stereo jack
connectors. 2 V maximum.
4.- INPUTS: microphone or balanced line inputs, XLR and 6.3 mm stereo jack connectors. Accepts
balanced and unbalanced microphone signals and different level line signals.
INSTRUCTIONS FOR USE
- The SR-1602 is a feedback suppressor based on the processing and analysis of content in the frequency
of the input audio signal and the elimination of components in the frequency, which produce the feedback
or link effect, through 12 high precision parametric notch filters per channel.
- The notch filter parameters are saved in the memory and are restored the next time the feedback
suppressor is used.
- The system does not need an initial setting.
- The feedback suppressor has 15 pre-set sensitivity levels, allowing the feedback detection sensitivity to be
increased or reduced.
- Follow the steps below for a correct system operation:
1.- Switch the system on.
2.- Depending on the input signal characteristics choose the suitable position on the MIC IN/LINE IN
control: MIC IN if it is a microphone signal or LINE IN if it is a line signal.
3.- With the INPUT LEVEL control, adjust the input signal level so that in the L and R level LED
indicator the signal is around -6 dBu. This is the optimum level to achieve a good sound/noise
ratio and optimum feedback detection.
Adjust the output signal level with the OUTPUT LEVEL control depending on the signal level required
by the mixer or power amp where the feedback suppressor is to be connected.
The LED CLIP indicator should not light up. If it lights up, the signal is distorted and the input signal
level must be reduced with the INPUT LEVEL control.
With the MONO/STEREO control you can choose whether the feedback detection is going to take
place only in the left channel, mono position, or in both channels, stereo position.
4.- To process the signal and delete sound feedback, the ON position must be chosen on the PROCESS
control.
In the OFF position the input signal is sent to the output in bypass and the processing does
not take place.
Activating and deactivating this control, you can easily check if the feedback suppressor is deleting
feedback.
