D. Level Matching

Many manufacturers claim that their source units

produce signal voltages in the area of 2 to 4 volts. However,

what they neglect to mention is that you only achieve these

incredible voltage levels when the volume is turned all the

way up. Try listening to that all of the time. By following

the level matching steps for the HPX you will be able to take

full advantage of the high-voltage output of your head unit.

Step #1. Disconnect the RCA cables leading into your

amplifiers, and make sure the only RCA cables between your

head unit and the HPX's main inputs are attached. Turn the

volume level knob on the HPX to maximum.

Step #2. Play a favorite tape or compact disc that

contains consistent, dynamic music and turn the source

unit's volume control up to its maximum level (NOTE: Some

source units may produce distortion or "clipping" when their

volume controls are turned all of the way up. If this happens,

you will hear distortion even at low levels when you connect

the rest of the system. If this is the case, lower the source

unit's volume level until you no longer hear distortion.) The

volume control on the HPX will now be the master volume

control.

Step #3. Using a small screwdriver, adjust the "Input

Gain" control on the top of the HPX until the yellow

"Overload" LED starts to flicker with

the music.

Step #4. Turn off the entire system

and attach the output RCAs from the

HPX to the next component in line.

Step #5. Turn down the gain control

on your amplifiers to the least sensitive

setting (turning the gain control counter

clockwise.) This will allow you to drive a

hotter signal in to your amplifiers. For

• Important Tip •

If the OVERLOAD light does not come on because of the low

output of the source unit, turn the Input Gain to maximum.

Please refer to the manufacturers specifications on input voltage

to determine whether you will need to decrease the "Input Gain"

on the HPX to avoid clipping the next component in line. If the

next component in line is an AudioControl component, there is

no need to re-adjust the "Input Gains", because they can handle

the hot signal voltage the HPX produces.
