In order to achieve maximum signal-to-noise performance from
a high quality auto stereo system, it is desirable to use high
signal levels wherever possible in the interconnect cables. High signal
levels will reduce the effect of induced noise. The peak level of an audio
signal is usually determined by the clipping level of electronic
components. The following procedure should be used as a guide before
the system installation is completed.
Adjustment of source unit output and
PEQ-114 input:
1.
Turn
PEQ-114 volume control fully counterclockwise.
2.
Turn source unit volume 1/2 to 3/4 of maximum.
3.
Adjust the
PEQ-114 input gain fully counterclockwise.
4.
Play a CD or cassette. A loud music selection is desired.
5.
Turn
PEQ-114 volume control clockwise to a comfortable
listening level, about 1/2.
6.
Adjust the input gain control clockwise until the onset of
audible distortion. Then adjust the control counterclockwise
slightly. This setting will minimize system background
noise and prevents overloading the
PEQ-114.
The four bands (Sub, Low, Mid, and Treble) on your
PEQ-114
have been designed to adjust the frequencies that are most
often out of balance in a car.
1.
To achieve the tonal balance you desire, listen to
some favorite music selections with the
PEQ-114
bands set “flat”, that is, with the knobs straight up.
Listen for individual instruments that seem too loud
(or too soft) and look up the instrument in the
Frequency Distribution chart on the facing page to
see which frequencies they represent.
2.
Looking at the Diagram on page 6, find the boost/cut
control that best matches the instrument you want to
adjust.
3.
Turn the control down (or up) until the instrument
blends with the rest of the music.
