THE AUTOMATION SYSTEM
The GS3000 has a comprehensive automation system capable of controlling all of the large mute
switches on the console and also to remotely control the transport controls of an external machine such
as a multitrack recorder, a hard disk recorder or a MIDI sequencer.
T HE M UTE S YSTEM
The GS3000 includes a 'soft' mute system controlled by an internal microprocessor which
gives far greater control and versatility than the conventional systems found in other
consoles. A ramped FET audio element in the audio path of each channel and monitor
signal path provides silent muting under control of the microprocessor. The mutes on the
stereo input channels and aux masters 5 & 6 are also controlled by the internal
microprocessor. The red LED indicator in the mute switch always indicates the status of
the channel (illuminated = muted, off = not muted).
Operational Features
MANUAL MUTING - Press a mute switch to turn a channel on or off. The switch cap
illuminates if the channel is muted. You can also turn off (clear) or turn on (set) all the
console mutes with a single key press.
4 MUTE GROUPS - Combine selected mutes under control of a master switch. Channel
and monitor path mutes can be made 'ALL SAFE' so that they are not affected by the
groups.
128 MUTE PATCHES - Store and recall the console mute settings in numbered
patches. Includes 3 digit display, auto increment, channel and monitor 'ALL SAFE'
function.
MIDI INTERFACE - IN, OUT and THRU sockets to interface with external sequencers,
effects devices and control units. Includes MIDI machine control (MMC) to control the
transport controls of multitracks, hard disk recorder, sequencer. MIDI dump to archive and
recall console settings. MIDI note on/off messages associated with channel mutes.
SOLO-IN-PLACE - Check the contribution of individual signals within the main mix 'in
place' by pressing the associated mute switches. Includes a separate 'SAFE' facility so
that selected channels are not muted when solo is activated. The last solo setting can be
recalled for instant comparison with the mix.
P OWER U P AND P OWER D OWN
The mute settings are remembered when power is removed from the console. A power
down circuit detects falling voltage and writes the settings to non-volatile memory. On
power up these settings are restored. The mute group, patch, solo safes, and mode
settings are held in similar memory.
T HE M UTE S WITCH
Press MUTE once to mute the audio signal.
The red LED indicator will turn on. The audio signal will turn off (channel muted).
Mute affects the post-fade aux send signal.
Press MUTE again to turn the mute off.
