(15) Amp Clip LEDs
The red Amp Clip LEDs illuminate when the input levels to the internal
amplifiers are too high. It is acceptable for these LEDs to come on
momentarily every now and then but the Main or Monitor Master Volume
(depending on which signals have been routed to the amplifiers: see
(16) below) should be turned down if the Amp Clip LEDs illuminate
consistently.
NB! Continued use of the GigRac with the Amp Clip
LED illuminated could cause serious damage to your
GigRac and your loudspeakers!
(16) Internal Amplifier Source Select Switch
This switch determines which signals are routed to the internal power
amplifiers. The options are: Main L to amp 1, and Main R to amp 2, or,
Main L + R to amp1, and monitor to amp 2. See the diagram opposite.
(17) Main Output Meters
The dual 10-segment output meters show the signal levels being fed to
the internal power amplifiers. See (16) above.
It is best to aim to have the red 10dB LEDs lighting up regularly during
the loudest signals peaks playing through your GigRac and the 16dB
LEDs flicking on very occasionally. This will ensure that a good level is
passing through the mixer.
(18) Record Outputs
The Record Outputs (L & R) are for connecting a recording device such
as a cassette or mini disk recorder.
The signal output at the Record Output sockets is a post fade signal
derived from the Main Mix outputs. The amount of signal level leaving
the GigRac via the Record Outputs is determined by the Main Master
Volume control (10) .
(19) Playback In
The Playback In connectors allow you to playback from your recording
device through the Main outputs/Speakers/Headphones. A useful tip is
to press the standby mute switch (20) , this mutes all other inputs to
