Connections & Control Panel Features continued
7. Gain Control 1/2 – This control allows you to adjust the overall
output level for channels 1/2. Turn clockwise to increase, and
counter-clockwise to decrease. With the source unit set to 75%,
adjust this knob to the point where the Maximized light shines
briefly. This will be your optimal gain setting.
8. High Pass Crossover Frequency 1/2 – 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 man-
ufacturer will provide increased speaker reliability and optimum
sound quality. The ACX-650.5 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. Please note that there are 3 of these LEDS - one
for channels 1/2, 3/4, and 5. 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. Input mode – If you have both front and rear input signals avail-
able - either by speaker level or line level - set this adjustment to 5
Ch mode. If you only have 2 signal wires, then set this to 2 Ch and
the signal received on inputs 1/2 will be distributed out to 1/2, 3/4
and 5/6 amplifier outputs
11. Gain Control 3/4 – Similar to the gain control for channels 1/2,
this control allows you to adjust the overall output level for
channels 3/4. Turn clockwise to increase, and counter-clockwise to
decrease. With the source unit set to 75%, adjust this knob to the
point where the Maximized light shines briefly. This will be your
optimal gain setting.
12. High Pass Crossover Frequency 3/4 – Similar to the High Pass
Crossover control for channels 1/2, this setting controls the High
Pass Crossover for channels 3/4. Set this according to your speaker
manufacturers recommended setting, usually found on the back
page of the their documentation or manual.
13. Gain Control 5 – This control allows you to adjust the overall
output level for channel 5. Turn clockwise to increase, and count-
er-clockwise to decrease. With the source unit set to 75%, adjust
this knob to the point where the Maximized light shines briefly.
This will be your optimal gain setting.
14. Crossover (type) – Channel 5 crossover allows you to set a High
Pass for something like a center channel. Because, you know,
options. Likely though, you be setting this wonderful device in a
more traditional way where this 5th channel output is a sub. If so,
make sure this switch is set to Low Pass.
