act LED (µ-mute)
This red LED lites whenever a Mute command is issued from the Micro. This can be from any of the Sequenced or Manual Mute Scenes or from a received MIDI Note command.Whether or not the channel responds to that mute command is determined by the status of two SAFE switches:the global Input Micro Safe switch (near master faders), or the channel Mute Safe switch.
mute safe
This switch "safes" the channel from external mute commands (micro, VCA,SIP). By default,theVCA and
act LED (VCA)
This red LED lights whenever a mute command is coming from an assigned VCA. Each VCA Master has an associated Mute switch. When depressed,any channels assigned to thatVCA Master will go to a fader full- down condition (max attenuation),and the channel mute will be activated. A jumper in the VCA Master fader block can defeat the mute function; in that case, the channels still go to fader
VCA assign
These 12 lit switches are used to assign a channel to any of the 12 VCA Masters.The channel gain is controlled by the sum of the voltages of the local fader and any of the assignedVCA Masters.TheVCA control circuit- ry is designed so that even if a channel is assigned to all 12 masters, and those masters are all at +10dB boost (total of +120dB theoretical gain!), the local fader (or any Master fader) ,when pulled down,has enough elec- trical
