Master Functions:
17. PHANTOM POWER: Applies +48VDC voltage to the input XLR connectors to power microphones
requiring it. If phantom power is used, do not connect unbalanced dynamic microphones or other devices to
the XLR inputs that cannot handle this voltage. An LED indicates when phantom power is on.
18. EFFECTS SELECT: There are four pre-programmed reverbs built into the console ranging from small to
large. Use this switch to select the reverb that best fits the style of music being performed.
19. EFFECTS LEVEL: The amount of the effects signal sent to the main outputs is determined by this control.
The channel effects send levels must also be turned up for reverb to be present
20. EFFECTS Mute/PK LED: This LED lights when the effects send level from the channels approaches 6 dB of clipping.
Reduce the channel send levels if this blinks often. This light also illuminates when the effects output is muted.
21. EFFECTS MUTE: This switch mutes the effects instantly. Although reverb can sound good on music, it can
be very distracting on spoken word. This switch allows the operator to quickly mute the reverb output when
vocal mics are used for speaking.
22. FEEDBACK FERRET SETUP: The Feedback Ferret has three modes of operation. Normal, when it is
scanning for feedback and placing and removing notch filters; Setup, when it is establishing fixed filters that
will be stored; or Bypass. When the blue LED is on, it is in the normal mode and is looking for problems to
solve. If the switch is pressed and held for three seconds, the LED will flash once and the Ferret will be in the
setup, or learn mode. If the switch is pressed and held for six seconds, the LED will flash twice and the
Feedback Ferret is in bypass mode. Please read the S14 setup instructions later in this manual for detail
instructions on setting the Ferret.

23. AUX AND REC OUTPUT LEVELS WITH AUTO-LEVEL: These are the master output controls for the
Aux and Record outputs. The record output is unbalanced stereo, the aux output is balanced mono. The
signal can either be unprocessed or automatically leveled with an automatic level control (AUTO-LEVEL)
circuit. The AUTO-LEVEL will keep the levels within a narrow dynamic range to maintain higher average
levels for tape or hearing assisted feeds. The AUTO-LEVEL circuit is enabled by depressing the concealed
switches using a small tool. The circuit is active when the switch is in the depressed position.
24. NOISE REDUCTION THRESHOLD: The solo and the choir groups have adjustable threshold downward
expanders that reduce noise by lowering the signal when the level drops beneath a set point. This not only
cleans up background noise, but also reduces feedback problems by attenuating mics assigned to this group
when there is no activity. An LED indicates that the group is being attenuated. To disable noise reduction, set
the control to minimum (full counter clockwise).
25. COMPRESSION THRESHOLD: In addition to noise reduction, soft knee compression is available for both
the solo and the choir groups. The threshold is adjustable to set the amount of compression desired. An LED
illuminates to indicate the group is being attenuated. The control should be set so that the light only illuminates
at peaks and is not consistently on. To disable compression, set the control to maximum (full clockwise).
