i. Solo and Choir Compression controls set full clockwise.
(Master Section)
j. Vocal enhance inactive (LED off)
k. Turn off the Feedback Ferret by pressing and holding the
Feedback Ferret button until the Blue LED blinks twice.
When you release the button, the LED should be off.
l. If any of the microphones used with the system will require
+48V phantom power, turn it on at this time.
Setting the mixer to amplifier system gain
This adjustment is an important part of optimizing the performance
of the S-14. This adjustment will help minimize noise and distortion,
and ensure that the automatic mixer, compressors and noise
reduction expanders will have the proper signal levels to operate.
a. Set the power-amplifier mode switch on the rear of the unit.
This switch connects the power amplifiers to either the Left
and Right outputs or to the main output (Left + Right) and
Monitor 1. (S-14P Only.)
b. Connect a CD player, tape machine or other music source
to line input 13/14 (Left and Right)
c. Turn on the sound system by first powering up the mixer
and associated equipment such as equalizers and crossovers
then turn on the power amplifiers last.
d. Start playback of your music source.
e. Set the MAIN, MON 1 and MON 2 master Faders to 0
(full up).
f. Set the Channel 13/14 fader‚ Monitor 1 and Monitor 2 Send
controls to 0.
g. Slowly increase the channel 13/14 input gain control until the
0 LED on the S-14 meters blinks.
h. Set the headphone/meter Source Select switch to Mon 1
and confirm that the meter peaks to 0.
i. Repeat (g) for Mon 2.

j. Now adjust the S-14 main-output trim until the sound in the room is as loud as you normally expect the
system to be operated. (On The S-14AP, use the amplifier input level controls on the back). *
k. Repeat (I) for Monitor 1 and Monitor 2 outputs using the power amplifier input controls instead of the
main trim control.
* The maximum sound level for the system is actually higher because of the headroom of the mixer. The
contractor may choose to make this adjustment by setting the S-14 trim control to 0 attenuation (full
clockwise) and then adjusting amplifier gains, but the trim control makes this job easy.
