Input modules

1

A/B switch

This switch selects the signal source of the input module. Select INPUT A (XLR type) or INPUT B (1/4” phone type).

20dB pad switch

2

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

3

GAIN 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 indicator 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.

high pass ﬁlter switch

80

This switch cuts the input signal below 80 Hz at 12dB/octave. The ﬁlter is turned on when the switch is pressed in.

By using the high pass ﬁlter, you can reduce or eliminate wind noise, mic pop noise, and power supply hum etc.

6

EQ controls (HIGH, MID FREQ, MID, LOW)

This is a 3-band equalizer with center frequencies, range, and type as shown below.

HIGH: 12 kHz +/–15dB shelving type MID: 250 Hz ~ 5 kHz (variable) +/–15dB peaking type LOW: 80 Hz +/–15dB shelving type The frequency response is ﬂat when the knob is in the center position.

3

EQ switch

This switch turns the EQ on/off. When the switch is pressed in the EQ is on. In addition to bypassing the EQ when it is not being used, this switch provides a convenient way to compare the equalized and unequalized signals.

AUX 1 / AUX 2 controls

7

These adjust the signal level that is sent to each output AUX SEND 1 and AUX SEND 2. These signals are pre-fader (i.e., they are taken from before the fader adjustment). Nominal level is at 3 o’clock position.

AUX 3 / AUX 4 / AUX 5 controls

8

These adjust the signal level that is sent to each output AUX SEND 3, AUX SEND 4 and AUX SEND 5.

The signals controlled by AUX 3 and AUX 4 will depend on the setting of the PRE switch.

• When the PRE switch is not pressed They control the post-fader signal.

• When the PRE switch is pressed They control the pre-fader signal.

AUX 5 controls the post-fader signal. Nominal level is at 3 o’clock position.

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.

Fader

C

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.

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.

ON switch

This switch turns the stereo module on/off. When the switch is pressed the stereo 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.

PFL switch

PFL is an acronym for Pre-Fader Listen. This switch allows you to monitor the signal of the stereo 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.
