8. High 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-300.2 amplifier has selectable high pass crossover

frequencies at 80 Hz, 120 Hz, and a "bypass" option. The amplifier

reproduces the frequency range above the selected crossover

frequency.

9. Maximized – This LED will shine when the signal is approaching

the clipping point. 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. GTO™ Signal Sense – In the ON position, the ACX-300.2 amplifier

will gracefully turn on when it detects an incoming audio signal

and turn off 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 or 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 mov-

ing the switch to the OFF position and use a switched 12v trigger

from the vehicle.

**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.

11. 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.
