ENGLISH
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 INPUTS.
* 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 sure 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 minimum settings before
operating the switch, to avoid risk of loud noises that could cause hearing loss or device damage.
20. PHANTOM POWER INDICATOR
This indicator lights up when the phantom power is switched on.
CONNECTORS
1. CHANNEL INPUTS
BALANCED MIC 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 level 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 between 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, sleeve) phone jacks that support bi-directional
operation.
NOTE: Connection to an 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 connectors. Two types are provided: Jack type and RCA pin type.
For stereo signals, you need of course to connect both Left and Right channels.

ENGLISH
Channels CH9/10 and CH11/12 can also be used for mono signals. If you need to connect a mono signal,
then use only the L MONO Jack input. When the mixer detects no connector in the R input, it will spread the
signal of the L MONO Jack input over both L and R channels.
NOTE: Channels 9/10 and 11/12 provide 2 types of inputs: jack and RCA connectors. Please use only one
of these inputs for each channel. Never use both input types at the same time on the same channel.
4. STEREO RETURN L (MONO), R JACK
These are unbalanced 1/4" TRS phone-type line input jacks. The signal received by these jacks is sent to the
MAIN bus and AUX buss. These 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. When the mixer detects no connector in the R input, it will spread the
signal of the L MONO Jack input over both 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 monitoring.
You can adjust the signal level using the TAPE IN control in the MAIN CONTROL SECTION.
6. REC OUT RCA connectors
The REC OUT connectors send the pre-fader signal from the master bus. U can use this output for
recording.
7. SEND JACKS
These are unbalanced phone jacks
* AUX
These jacks output sends the signal form AUX bus. You can use this jack, for example to connect powered
stage monitors.
* EFX
You can use this jack for example to connect an external effect unit.
8. FOOT SWITCH JACK
A foot switch can be connected to this phone input jack and can be used to turn the digital effects ON/OFF.
9. GROUP OUT (ALT3/4 ) JACKS
Unbalanced 1/4" Jack outputs for the signals of ALT3/4.
10. MAIN L/R OUTPUT JACKS
Balanced 1/4" Jack outputs. You can use these outputs to connect the power amplifiers for you main
speakers, or you can use them when you wish to record the signal that is also influenced by the main output
faders.
11. CONTROL ROOM OUTPUT JACKS
These unbalanced 1/4" Jack outputs are controlled by the CTRL ROOM /PHONES CONTROL and are
generally used to connect a monitoring system.
NOTE:The signal monitored by these outputs is selected by the settings of the LEVEL METER SIGNAL
SWITCHES, the TAPE IN switch, and the PFL switches on the input channels.
12. PHONES JACK
Stereo headphones connector.
NOTE:
The signal monitored by these jacks is selected by the settings of the LEVEL METER SIGNAL SWITCHS, the TAPE IN
switch, and the PFL switches on the input channels.
