Large Fader

AUTOMATION MUTE: (Channel Mute) Cuts the Large Fader audio output

The MUTE button is the on/off switch for the Large Fader

Activates the 968 MUTE button

Not activated by the 968 MUTE button

Controlled by automation

•

Illuminates in red when engaged

LARGE FADER: Controls the output level of the Large Fader audio path

Full-size 100mm resistive fader

+10dB of gain

∞

dB of attenuation

Unity gain when set to 0dB

0dB fader bypass (in via automation system)

Controlled by automation

NOTE:

A 0dB Large Fader bypass can be applied via the automation system.

This feature is useful if an additional Large Fader gain stage is not needed or when

using DAW automation/worksurface control.
