12. Communications LED – This LED turns on when there is USB
activity between the D-6.1200 and your computer during set up.
13. GTO™ Signal Sense – In the ON position, the D-6.1200 amplier
will turn on gracefully when it detects an incoming audio signal
on inputs 1 and 2, and it will turn o after a period of time when
the audio signal fades away to silence. In some situations, factory
installed audio systems may turn on or “wake up” due to conve-
nience features like door chimes, alarms, and cell phone signals
that trigger the source unit in the vehicle to come on. To prevent
these from turning your audio system on unexpectedly, you can
bypass the GTO™ circuit by moving the GTO™ switch to the OFF
position and use a switched 12-volt signal connected to the Re-
mote In terminal instead.
14. MILC
™
Source Clip LED – The MILC™ (Maximum Input Level
Control) patent-pending level-setting circuit (on inputs 1-2 only)
prevents clipping and damaging distortion. It calculates when the
waveform of an incoming audio signal is clipping, and if it is, this
LED will fulll its destiny and shine forth.
With this advanced feature, you are able to optimize the level of
the incoming audio signal until the Source Clip LED is just about
to come on. If the LED comes on during normal operation, you
should adjust the level of the audio signals before they reach the
D-6.1200.
15. Maximized Input LEDs – These LEDs illuminate when a maxi-
mum audio signal is present on any of the analog audio inputs.
During power-up, these LEDs and the output LEDs will turn on
momentarily, one after the other. Turn down the levels if these
LEDs are on a lot.
16. Maximized Output LEDs – These LEDs illuminate when there is
maximum signal present on any of the analog audio outputs. Turn
down the output levels if these LEDs are on a lot.
