4 MONI (monitor) control

This knob controls the level of the signal that is sent from each channel to the MONI bus. Since this control is placed before the channel fader, it controls the level independently from the channel fader setting.

5 EFFECT control

This knob controls the level of the signal that is sent from each channel to the EFFECT bus. Since this control is placed after the channel fader, the signal level will be affected by the channel fader setting.

6 Group select switches

These switches send the signal of each channel to GROUP buses 1~4. When the 1 / 2 switches are on (pressed in), the signal will be sent to the GROUP buses 1/2. When the 3 / 4 switches are on (pressed in), the signal will be sent to the GROUP buses 3/4. When both switches are on, the signal will be sent to GROUP buses 1/2 and 3/4.

7 PAN (panpot) control

BAL (balance) control
The PAN knobs (channels 1~8) set the stereo position of the signal that is sent to the GROUP buses 1/2 or 3/4. The BAL knobs (channels 9~12) set the balance between the left/right channels, and assign the signals received at inputs 9 L (MONO) and 11 L (MONO) to the GROUP buses 1/3, and the signals received at inputs 10 R and 12 R to the GROUP buses 2/4. If signals are input monaurally to input 9 L (MONO) or 11 L (MONO), the same signal will be sent to groups 1~4.

8 Channel fader

This controls the output level of the input channel signal, adjusting the volume balance between channels. The faders of unused channels should be lowered.

Connector section

1 INPUT
MIC (1~8)These are balanced XLR type mic input jacks (1: ground, 2: hot, 3: cold). These inputs are compatible with 50~600 microphones. LINE (1~8)These are balanced TRS phone type line input jacks (T: hot, R: cold, S: ground). These inputs are compatible with 600 ohm line level devices. It is also possible to connect unbalanced phone plugs, but noise may enter the signal if the cables are long or if the location is susceptible to electromagnetic interference. Note: It is not possible to connect both the MIC INPUT jack and the LINE INPUT jack for an individual input channel. Only one or the other jack may be used. INS I/O 1~4These are input/output jacks placed between the equalizer and fader of input channels 1~4. The nominal input level/impedance is 0dB/600, and the nominal output level/impedance is 0dB/10k. Devices such as graphic equalizers, compressors or noise lters can be connected here. The INS I/O jacks provide bi-directional connections using TRS (tip, ring, sleeve) phone jacks. These connections require a special insertion cable such as shown in the following diagram.

2 RTN L (MONO), R

These are unbalanced phone type line input jacks, with a nominal input level and impedance of +4dB/600. The signals which are input from these jacks are sent to the ST bus and the MONI bus. Normally, these jacks are used to receive the return signal from an external effect device such as reverb or delay, but they can also be used as auxiliary stereo inputs. If only the L (MONO) jack is connected, the same signal will be sent both to the R jack and L jack, for monaural input.

3 SEND MONI 1, EFFECT/MONI 2
These are unbalanced phone type output jacks. The nominal input level and impedance are +4dB/600. The MONI 1 jack outputs the MONI bus signal, and the EFFECT/MONI 2 jack outputs the signal of the EFFECT bus or MONI bus. These are used to send signals to an external effect unit or to a monitor system such as a cue box.

4 INPUT 9~12

These are unbalanced phone type stereo line input jacks, compatible with 600 line level devices. If only the L (MONO) jack is connected, the same signal will be sent both to the L and R jacks, for monaural input. In this case, the group select switch (channel control section 6) will send the same signal to the group buses 1/2 or 3/4. These are balanced XLR type output jacks with a nominal output/impedance of +4dB/600. They provide stereo output of the mixed signal, and are normally connected to a power amp etc. which drives the main speakers. These outputs can also be used in order to record the signal at a level adjusted by the ST fader. These are unbalanced phone type output jacks which output the signals of group buses 1~4, with a nominal output/impedance of +4dB/600. Normally these are connected to the input jacks of an MTR or an external mixer.

5 ST OUTPUT (L, R)

6 GROUP OUTPUT 1~4

7 C-R OUT

This is a stereo phone type output jack for connection to a monitor system etc., with a nominal output/impedance of +4dB/10k. The source monitored by this jack is selected by the C-RPHONES output select switch (master control section C). Note: An insertion cable can also be used when connecting this jack to a stereo monitor system.

Phantom Power Warning To prevent hazard or damage, connect only microphones and cables that conform to the IEC268-15A standard.

1 POWER switch

When this is on, power is applied to the unit. When turning off the power, the rule for audio equipment is to turn off devices in the order of their closeness to the speakers (normally beginning with the power amp).

2 PHANTOM switch

This switch turns the phantom power on/off for all channels 1~8. Use this when you are using condenser microphones. When this switch is on, +48V DC will be supplied to pins 2 and 3 of all XLR type MIC INPUT connectors. If you do not require phantom power, be sure to set this in the OFF position. Note: Although it will not cause problems to connect balanced dynamic microphones or line level devices with this switch turned on, connecting unbalanced devices or devices for which the center of the transformer is ungrounded may cause hum or malfunction.
