21A/B switch

This switch selects the signal source of the input module.

Select INPUT A (XLR type) or INPUT B (1/4” phone type).

220dB pad switch

4This is a 20dB input pad (attenuator) that affects INPUT A and INPUT B.

5If the level of the input signal is too high for adjustments to be made using the GAIN control alone, use the pad to attenuate the signal to an appropriate level. The pad is on when this switch is pressed in.

3GAIN control

This controls the gain of the preamp for INPUT A and INPUT B. Gain is variable to a maximum of 44dB.

The GAIN control is always used in conjunction with the SIGNAL indicator and the PEAK indicator. Adjust the GAIN control so that the SIGNAL indi- 6 cator is always lit when an input signal is present, and the PEAK indicator lights occasionally. If the PEAK indicator lights frequently, lower the GAIN

control to prevent the signal from distorting.The following table shows usual settings for the GAIN control.

Signal source	GAIN control position	20dB pad switch
Dynamic mic (low level)	–60 ~ –50	off
	–16 GAIN –60
Condenser mic (high level)	–35	off

4SIGNAL indicator and PEAK indicator

When the post EQ signal level (nominal level 0dB) reaches –10dB, the SIGNAL indicator will light. This indicator indicates that a signal is being input.

8When the post EQ signal level reaches 3dB before clipping level, the PEAK indicator will light. This indicator indicates that the signal has approached

clipping level. Set the signal level based on the status of the PEAK indicator. For the procedure, see the explanation for 3GAIN control.

9Assign switches (1-2, 3-4, ST)

These switches assign the signal of the input module to the group outputs and the ST output. The PAN control located below adjusts the stereo posi-

9tion of the signal between the odd (ODD) group and left (L) outputs and the even (EVEN) group and right (R) outputs.

		0PAN control
0		This knob adjusts the stereo position of the signal between the stereo L and
0
		R, and between the odd/even groups. For example if this knob is turned all
	A	the way to the left, the signal will be sent only to the L and odd (ODD) groups
		whose assign switches are pressed. If it is turned all the way to the right, the

Bsignal will be sent only to the R and even (EVEN) groups. If the knob is set

to the center position, the same amount of signal will be sent to the stereo L and R, and the odd/even groups.

AON switch

This switch turns the input module on/off. When the switch is pressed in the input module is on. Be sure to turn off input modules that are not in use. Even when a module is off, the SIGNAL and PEAK indicators will light if a signal is being input. You can also use the PFL switch to monitor the signal even if a module is off.

CBPFL switch

PFL is an acronym for Pre-Fader Listen. This switch allows you to monitor the signal of the input module regardless of the fader position, the settings of the ON switch, the group assign switches, or the AUX settings. As the name suggests, the signal is taken pre-fader (post EQ). You may listen to an individual module, or to two or more modules simultaneously. The PFL indicator located at the top of the STEREO module will light when a PFL switch is on.

CFader

This adjusts the signal level that is sent to the various outputs. Faders are used individually or in conjunction with the faders of the other input modules to create the desired mix balance. A position at the zero (0) marking is the nominal level. Raising the fader above 0 provides up to 10dB of gain.

tion of the signal between the odd (ODD) group and left (L) outputs and

5the even (EVEN) group and right (R) outputs.

7BAL/PAN control

The BAL/PAN knob adjusts the balance or the L/R position of the stereo module signal. For example if this knob is turned all the way to the left, the signal will be sent only to the L and odd (ODD) groups whose assign switches are pressed. If it is turned all the way to the right, the signal will be sent only to the R and even (EVEN) groups. If the knob is set to the center position, the same amount of signal will be sent to the stereo L and R, and the odd/even groups.
