Initial Settings And Tuning; Input Mixer Level And Polarity - µ-Dimension Glow DSP8 Instruction Manual

Initial Settings and Tuning

This chapter will get you started on system tuning. The key here is to
set everything in the DSP8 so that the speakers are protected from
frequencies that could damage them, the gain structure and signal
levels are optimized to ensure maximum signal levels, and everything
is set to be neutral within the crossover, EQ, and delay sections.
Input Mixer Levels and Polarity
One of the great features in the DSP8 is the signal level indicator,
which will allow you to adjust the input and output levels without the
need to use the oscilloscope.
To accomplish this, you must use an appropriate test tone. You must
first ensure that the source unit output levels are set to their
maximum un-distorted levels.With the source unit and any other
devices in line prior to the DSP8 set to their maximum undistorted
output signal levels, it is now possible to set input and output levels
within the processor.
Begin by setting the main signal level control to the 0 dB setting. Set
the signal input to the processor from the source unit at its maximum
undistorted level. Using the 1 kHz 0 dB down signal, adjust the input
gain control for each input to be used so that the signal level just
lights up the first red bar on the indicator. Do this for each input
