8. Low Pass Crossover – A crossover allows you to match a speaker
to the frequency range it is designed to handle. Choosing the
crossover point recommended by the speaker manufacturer
will provide increased speaker reliability and optimum sound
quality. The ACX-600.1 amplifier has selectable low pass crossover
frequencies at 80 Hz, 120 Hz, and a “bypass” option. The amplifier
reproduces the frequency range below the selected crossover
frequency.
9. Gain Maximized LED – This LED indicates when the ACX-600.1
amplifier gain has been maximized for optimum performance.
With your source unit turned up to 75%, use your gain controls to
dial in the output by watching for this LED to shine, then back it
off just a touch.
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. Input Level – Use this switch to specify which type of signal input
voltage type you are using - high is speaker level & low is RCA line
level.
14. Remote Level Port – Using the cable that came with the ACX-
600.1, connect your optional ACR-1 level control knob here.
15. 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.

**Pro tip - if using speaker- level/high-level inputs, you’ll
need some RCA ends on the ends of the speaker wire
to attached to the RCA inputs. Setting the Input Level
to High of course.
