channel fader features

This momentary switch is used to program the channel mutes when the Micro

is in EDIT Mode. Pressing this switch will assign/un-assign it to a mute scene

(either Sequenced or Manual), the internal yellow LED will blink to show an

assignment.The operator uses these blinking LEDs to review the mute pattern

being edited.These buttons are also used to send MIDI mute info when the

Micro is in normal operation mode and MIDI Mutes is ON (see Utility).

Pressing this switch sends a Note On/Off command that can be recorded on

an external MIDI sequencer. If a corresponding Note On/Off command is

received,the yellow LED lites up steady,and a mute command is issued to the

channel.

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.

This switch "safes" the channel from external mute commands (micro,VCA,

SIP).By default, the VCA and Solo-In-Place (SIP) mute commands are safed,but

there are two jumpers located on each fader circuit board to exclude each of

them.The micro mute commands (Man Mute, Seq Scene or MIDI mutes) are

always affected by the safe.

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 that VCA 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 full-down,but the channel mute is not activated.

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 assigned VCA Masters.The VCA control circuitry is

designed so that even if a channel is assigned to all 12 masters,and those mas-

ters are all at +10dB boost (total of +120dB theoretical gain!),the local fader

(or any Master fader) ,when pulled down, has enough electrical over-travel to

fully attenuate the channel.Furthermore, the control voltage is electrically lim-

ited to a maximum of +20dB gain to prevent excessive channel boost.
