Control Panel Features
9. Gain Maximized LED - This LED indicates when the ACX-300.1
amplier gain has been maximized for optimum performance.
10. AccuBASS® - This switch enables the renowned AccuBASS® bass
enhancement to work it’s magic on the lower bass of speaker
outputs.
11. AccuBASS® Threshold – Sets the level at which AccuBASS® will
begin to work.
12. AccuBASS® Level - Adjusts the level of the AccuBASS® enhance-
ment circuitry.
13. GTO ™ Signal Sense – In the ON position, the ACX-300.1 amplier
will turn on gracefully when it detects an incoming audio signal,
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 convenience 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 switch to the OFF position and
use a switched 12-volt signal connected to the Remote In wire
instead.
14. RCA Inputs – This is where you connect your source signal to. If
using low level signals, make sure your Input Level setting switch
is set to Low. If you are using high or speaker level signals, set your
Input Level to High.
15. Remote Level Port - Using the cable that came with the ACX-
300.1, connect your optional ACR-1 level control knob here.
