CL-6 INPUT CONTROLLER

Trim Levels (688 only)

When the CL-6 is attached to the 688, the mini-faders on the 688 become dedi-

cated trim controls for inputs 7-12.

To adjust the trim level for inputs 7-12:

Turn the appropriate mini-fader on the 688. The trim gain is displayed on

the mixer’s LCD via the Input Settings screen.

Trim Levels (664 only)

When the CL-6 is attached to the 664, the mixer’s SELECT encoder may be used

to adjust trim for inputs 7-12 via the Input Settings screen.

To adjust the trim level for inputs 7-12:

1. Slide the input’s PFL switch on the CL-6 to the right to access the Input Set-

tings screen on the mixer’s LCD.

2. Turn the SELECT encoder to adjust trim for the input. The trim gain is dis-

played on the mixer’s LCD.

Using High-pass Filters

The High-pass Filter button on the CL-6 is a toggle, which turns the high-pass

lter off or on to a prede

ned setting of 150 Hz.

On the 688, the high-pass

lter may be adjusted to other frequencies via the Input

settings; however, if the button on the CL-6 is used, high-pass

ltering is turned

on at a set frequency of 150 Hz.

To turn on an input’s high-pass

lter:

Press the High-pass Filter button associated with the input.
The High-pass Filter LED illuminates amber when high-pass

ltering is on.

Press the button again to turn off the high-pass

lter.
