(1).If the input channel’s PFL switch is on( ),
then only the channel’s PFL output is sent
to the C-R OUT jacks, the PHONES and the
LEVEL METER.
(2).If the input channel’s PFL switch is off( ),
then either the main ,GROUP1-2, or GROUP 3-
4 signal is sent to the C-R jacks, PHONES and
the LEVEL METER determined by the MAIN
and GROUP toggle switches.

23. PHANTOM POWER SWITCH
This switch toggles phantom power on off. If you set
the switch on, the mixer supplies power to all channels
that provide XLR MIC input jacks.
Set this switch on when using one or more condenser
microphones.

18. CTRL ROOM /PHONES CONTROL
Controls the level of the signal output to the PHONES
jack and the CTRL ROOM L and R jacks.
19. LEVEL METER
This LED display shows the level of the signal selected
by the selection switches described in the 17 above
(LEVEL METER SIGNAL SWITCHES). The “0” point
corresponds to the standard output level of +4dB for
+4dB output (that’s the rated level) . The indicator
lights up red when the output hits the clipping level.
20. MAIN EQ ON/OFF Switch
The EQ ON/OFF switch is used to engage or bypass
the MAIN EQUALIZER. When the switch is in the
down position, the EQ is on and when the switch is up,
the EQ is bypassed.
21. MAIN STEREO EQUALIZER
The M1636FX/M2436FX provide a seven-band MAIN
STEREO EQUALIZER allowing you to control the
frequency response of the MAIN stereo mix bus signal.
Providing a maximum of 12dB of cut/boost for each fre-
quency band , this Graphic EQ is also extremely useful
tool for cutting the frequencies that cause annoying
feedback. The frequency is
fl at when the sliders are in
the center position. Moving a slider in the positive direc-
tion will boost that frequency by as much as 12dB, and
moving the slider in the negative direction will cut that
frequency by up to 12dB. And since the MAIN GRAPH-
IC EQUALIZER is stereo, the EQ curve is applied to
both the left and right signal at the MAIN OUTPUT.
22. PHANTOM POWER INDICATOR
This indicator lights when the phantom power switch is
turned on.
Be sure to leave this switch off ( ) if you do not
need phantom power.
When tuning the switch on ( ), be sure that only
condenser MICs are connected to the XLR input
jacks.
Devices other than condenser MICs may be dam-
aged if connected to the phantom power supply.
Note, however, that the switch may be left on
without problem when connecting to balanced
dynamic microphones.
To avoid damage to speakers, be sure to turn off
ampli
fi er (on powered speakers) before turning
this switch on or off. We also recommend that you
turn all out controls (MAIN master fader, ALT3/4
fader, etc.) to minimum settings before operating
the switch, to avoid risk of loud noises that could
cause hearing loss or device damage.

(15). TAPE IN PFL SWITCH
Set this switch on if you wish to output the TAPE IN
signal to the PFL bus
(16). TAPE IN CONTROL
This knob control the level of the playback signal that
is inserted to the master mixing bus from the TAPE IN
RCA jacks on the top panel.
(17). LEVEL-METER SIGNAL SWITCHES
These level-meter switches, together with the channel
PFL switches, select the signal that is sent through the
CTRL ROOM/PHONES control to the CTRL ROOM
OUT jacks, the PHONES jack, and the level meter.
NOTE:
24. POWER INDICATOR
This indicator lights when the mixer power switch is
turned on.
When this switch is on, the mixer supplies DC
+48V power to pins 2 and 3 of all XLR-type MIC
INPUT jacks.
