17. LEVE L METER SIGNAL SWITCHES
These level-meter switches, together with the channel PFL switches, select the signal that is sent to the
CONTROL ROOM OUT jacks, the HEAD PHONE jack, and the LEVEL MET ER.
If the input channel’s PFL switch is on , then only the channel’s PFL output is sent to the
CONTROL ROOM OUT jacks, the HEADPHONE jack, and the LEVEL MET ER.
If the input ch annel’s PFL switch is off , then the MAIN L/R signal, GROUP1-2 signal or
GROUP 3-4 signal can be m onitored via the CONTROL ROOM OUT jacks, the HEADPHONE jack,
and the LEVEL METER. Use the MAIN or the GROUP s witches to select the desired output to listen
to.
18. CTR L ROOM /PHONES CONTROL
Controls the signal l evel of the PHONE S and CONTROL ROOM outputs.
19. LEVEL METER
This LED display sho ws the level of the signal selected by the selection switches, like described in the
LEVEL METER SIGNAL SWITCHES ( 17) above. The “0” point corresponds to the standard output level of
+4dB.
20. M AIN EQ ON/OFF Switch
The EQ ON/OFF switch is used to engage or bypass the MAIN E QUALIZER. When the switch is in the down
position, the EQ is on and when the switch is up, the EQ is bypassed.
21. M AIN STEREO E QUALIZER
The MAIN STEREO EQUALIZER allowsyou to control the frequency response of the MAIN stereo mix bus signal.
Providing a maximum of 12dB ofc ut/boost for each frequency band , this Graphic EQ is also extremely useful tool for
cutting the frequencies that cause annoying feedback. Since the MAIN GRAPHIC EQUALIZER is stereo, the EQ curve is
applied to both the left and right signal of the MAIN OUTPUT.
22. PH ANTOM POWER INDICATOR
This indicator lights up when the phantom power is switched on.
23. PH ANTOM POWER SWITCH
This switch toggles the phantom power on or 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 that need to receive external power from the mixer.
NOTE
: When this switch is on, the mixer supplies DC +48V power to pins 2 and 3 of all XLR-type MIC INPUT jacks.
* 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 damaged 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 s ure to turn off amplifier (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 m inimum settings before
operating the switch, to avoid risk of loud noises that could cause hearing loss or device damage.
24. POWER INDICATOR
This indicator lights when power switch of the mixer is turned on.

CONNECTORS
1. CHANNEL INPUTS
BALANCED M IC XLR Connectors
These are balanced XLR-type input jacks (1: Sleeve, 2 : Hot, 3:Cold)
BALANCED LINE IN JACK Connectors
A standard 1/4” TRS phone jack is used for balanced or unbalanced line lev el signals, like used with most
electronic keyboards, synthesizers, tape decks and the line outputs from other mixers.
2. CHANNEL INSERT I/O JACK
These are input/output jacks located bet ween the head-amplifier and the high pass filter.
These jacks can be used to independently connect these channels to devices such as graphic equalizers,
compressors, and noise filters. These are 1/4” TRS (tip, ring, sl eeve) phone jacks that support bi-di rectional
operation.
NOTE: Connection to a n INSERT I/O jack requires a special separately-sold insertion cable such as
illustrated below.
3. CHANNEL INPUT JACKS
These are unbalanced stereo line input c onnectors. Two types are provided: Ja ck type and RCA pin type.
For stereo signals, you need of course to connect both Left and Right ch annels.
Channels CH9/10 and C H11/12 can also be used for m ono signals. If you need to connect a m ono signal,
then use only the L MONO Jack input. When the mixer detects no connector in t he R input, it will spread the
signal of the L MONO Jack input over b oth L and R channels.
NOTE:
Channels 13/14 an d 15/16 provide 2 types of inputs: jack and RCA connectors. Please use only one
of these inputs for each channel. Neve r use both input types at the same time on the same channel.
4. STEREO RETURN L (MONO), R J ACK
These are unbalanced 1/4” TRS phone-type line input jack s. The signal received by these jacks is sent to the
MAIN bus and AUX1/AUX2 busses. T hese jacks are mainly used to receive a return signal from an external
effect (reverb, delay, etc.)
NOTE: These jacks can also be used as an auxiliary stereo input. If you need to connect a mono signal, then
use only the L MONO Jack input. W hen the mixer detects no connector in the R in put, it will spread the
signal of the L MONO Jack input over b oth L and R channels.
5. TAPE IN RCA connectors
Use these RCA connectors when you want to connect a CD, DAT or other external sound source directly to the mixer for
