INPUT SENSITIVITY
IMPORTANT! Before you start, turn the input level controls to lowest position on all amplifiers and the
CFQ5.2.
1. Adjust the input sensitivity control of input 1 to produce the greatest possible signal level without
overloading your CFQ5.2 preamp. To do this, first turn the volume of the source unit to 2/3 of maximum
volume. If available on your source unit, set the maximum output to the
on
position. Find a CD or cassette
with a dynamic recording (vary high peaks in the music). Be sure all equalizer knobs are in their center
position (at 12 o'clock). Play the CD or cassette and adjust the master volume and the subwoofer volume
control of the CFQ5.2 to 3 o'clock. Take a flathead screw driver and adjust the input level control until the
peak light on the face of the preamp gently flickers. Back the input level adjustment up until the peak
indicator light is no longer flickering. This adjustment will provide you with the maximum output from the
CFQ5.2.
2. Continue playing your CD or cassette. Set the master volume control of the CFQ5.2 to 3 o'clock and the
subwoofer volume control to 12 o'clock. Now begin adjusting the gains on your amplifiers. Increase the
gain control on the amplifier until the onset of audible distortion and then back off the setting slightly. Do
this to each of the amplifiers or until all of the speakers blend correctly. Remember, always adjust to the
system to the weakest speaker.
3. If you are using input 2, you will repeat the above procedure. If there is no volume control for the
auxiliary unit, simply adjust the input level control until the peak LED starts to flicker. Once this is set,
play the source unit at a moderate volume and switch back and forth to verify that both input 1 and input 2
levels are adjusted evenly. If necessary, readjust the input levels until the output level between input 1 and
input 2 are equal.
Now that is finished, proceed with mounting the CFQ5.2. Enjoy your listening!
