PS-8810
DIGITAL SIGNAL PROCESSOR
The BSS PS-8810 has eight mic/line inputs, two main outputs and
eight AUX outputs Three-terminal removable barrier block
connectors are provided for the mic/line inputs and main and
AUX outputs.
Three-terminal removable barrier block connectors are provided
for the audio inputs.
Each input has an input selector switch.
• Slide it to the left (M) for microphone signal levels up to
5dBu (0dBu = 0.775 volts).
• Select the center position (L) for line level signals up to +20
dBu.
• Slide it to the right (P) to provide 24VDC to mics requiring
phantom power.
An Audio Input Section
Each input has a screwdriver-set, calibrated gain control to
compensate for different input source levels. The slot on the
control shaft points to the gain setting. The settings are labelled
for line level input. Add 25 dB to the scale if the inputs are
switched for microphone level signals.
Use a screwdriver to adjust the gain pot so that the input signal
level plus gain equals roughly 0dBu. You will need to know, or
estimate, the level of the input source. Setting the source signal
level to approximately 0dBu will provide 20dBu of headroom in
the input preamp. Some recommended settings are given in the
following table.
