H. Changing The Display Lens:
The artistic geniuses of AudioControl have chosen the
design of the display lens on your HPX, however, that does
not mean that you have to like it. In fact, you can customize
your HPX display by creating your own lens on a piece of
translucent paper and installing it by following these steps
1. Carefully remove the three no. 4 screws on the rear and
remove the metal cover.
2. Remove the one top 4-40 screw that holds in the
display bracket and carefully remove the bracket.
3. Replace the existing graphics with your “custom” graphics.
Figure 12 shows the size your graphics will need to be.
4. Line up the clear lens over the new graphics, hold against
the bracket, and reinstall in chassis using the 4-40 screw.
5. Replace the top cover and no. 4 screws.
F. Crossover Modules:
Additional crossover modules
for HPX are available from your authorized AudioControl
dealer, or you can create custom modules by using the
following formula:
7,200
Frequency (Hz)
Example:
For a 2,500 Hz module - 7,200/2,500 = 2.88K ohms
The 24 dB crossover module requires eight resistors of this value.
Note: Use
1
⁄
4
watt carbon or metal film resistors of a 5%
tolerance or better.
G. Bypassing The Crossover:
Depending upon your
system configuration, you may wish to not high-pass your
front and rear speakers and instead let them play full range.
Fortunately, the engineering gods at AudioControl have
thought of everything and given you the ability to bypass
the crossover. Just remove the chassis top and move the
CROSSOVER jumper from “Engage” to “Bypass” and
voilá - full-range front and rear outputs plus you get to keep
your lowpassed subwoofer output.
