At this point, the entire system is calibrated, with the exception of the power amplifier gain setting. To
set the power amplifier gain, you will require some equipment to measure SPL in the room area. Begin
by mixing all room areas together, and opening all divisible meeting areas. If your system consists of
several nonmixable subsections, mix all rooms that are possible.
Set all area wallplates to Music On, Mic Off. Inject the anticipated level signal into the Music Source
One input bus. Using the SPL measuring instrument, monitor each room and adjust each power ampli-
fier as necessary to achieve a uniform level throughout all areas.
Keep in mind that the ML-116 system will allow volume adjustment of +4 to -18 dB with respect to
unity, so you will want to adjust the amps close to the maximum desired level during this procedure.
The adjustment procedure is now complete.
