STEREO LINE INPUT CHANNELS - MUTE, VCA, SOLO and LEVEL CONTROL
Local Mute Switch - Internally Illuminated
Activation of this switch will mute the primary outputs as well as all pre and post fader auxiliary sends of the
channel. When depressed, it will illuminate RED, indicating the status of this local mute only; another LED
located beneath this switch indicates the status of any remote activated mutes. Activation of either mute
system will not affect the channel's metering or the Solo-PFL signals, these are both located Pre-Fader/Pre-
Mute. However, the channel's Solo-AFL signal is Post-Fader/Post-Mute (and Post-Assign), so if a channel is
muted (or not assigned), no Solo-AFL will be available.
Remote Mute Activated Led
This LED will illuminate red when a mute command is received from any of the possible 12 remote mutes (8
VCA mutes + 4 Mute Groups).
Scene Mute Preset Switches A Thru D
When any of these switches are selected, it will cause the input channel to mute (and Remote Mute LED to
illuminate) when the associated Mute Group switch within the master section is activated. Activation of a
scene mute affects the channel in the same way a Local Mute does.
VCA Status Indicator (CV= Control Voltage)
The VCA status LED will illuminate in varying levels of green in proportion to voltage being applied to the
VCA elements. This voltage is controlled by the channel fader as well as any of the 8 VCA master faders that
may be assigned to the channel. This LED will turn red if the voltage being applied approaches the
maximum allowable. The CV circuitry will then limit the voltage being applied to the VCAs to prevent the
channel fader gain from exceeding the 20dB design limit.
VCA Assignment Switches 1 Through 8
When any of these switches are depressed, it allows the associated master VCA level to have parallel control
of the channel VCA elements. Any combination of switches may be chosen, all of which will sum together to
create the final voltage being applied to the VCA elements. Maximum voltage being applied to the VCA
elements is limited and indicated by the VCA status (CV) LED turning red (see above). These switches also
act as presets for 8 additional scene mutes, but limited to the same assignment groups as the VCA. When
any of the associated VCA mute switches within the master section are activated, the channel will be muted
in the same manner as from the Mute Group section of the console.
Channel Level Meters
2 x 3 segment LED meter indicates pre-fader channel level. The top segment (1 left, 1 right channel) peak
indicator will illuminate red if any of the multiple sample points in the stereo signal chain approaches 3dB of
clipping. A yellow LED on each channel illuminates in the caution zone at a +8 reference level. The green
signal present LED first illuminates at approximately -30 and increases in brightness with level until it is at full
intensity on each channel. Best operation is achieved when the green LED’s are illuminated with average
input signals with only occasional short yellow/red bursts of the +8 and peak LED’s.
100mm VCA Channel Fader
This fader adjusts the voltage being applied to the channel’s VCA control electronics. This voltage is mixed
with any of the assigned VCA group voltages to create the final control voltage (CV) for the channel’s VCA
elements (as described above). These VCA elements controls the Post fader signal levels within the channel..
Solo Switch With Internal Illumination
This switch will illuminate yellow when activated. It will route signal to the master section for display on the
Master solo meters and into the monitor/headphone systems. A switch within the master section
determines if the signal is sampled pre fader or post fader/post pan pot. When in pre fader mode, it will
route the pre fader stereo signals to the master section. In post -fader mode, the channel post fader-post
left-center-right signal is fed to the master section where inclusion of the center signal to monitors and
headphones is determined. The master section also includes a SOLO CLEAR switch, which will cancel any
mute switches selected as well as an INPUT PRIORITY switch which will allow an input channel solo to
temporary cancel an output solo.
