POWER WIRING
The black wire should be chassis-grounded to a solid metal
ground. The red wire should be connected to the source
unit’s auto-antenna or accessory lead. If present, the white
wire should be connected to the battery or another positive
voltage source.
EQUALIZATION GOALS
The primary goal of the equalizer set-up is to produce a
smooth response approaching a desired curve, eliminating
or reducing peaks and valleys in the system response.
Systems could be equalized for a perfectly flat response, but
a flat response sounds very thin and bodiless. A better
approach is to attempt a final response similar to the room
response of a good home speaker.
Figure 3, shows some typical “good-sounding” system re-
sponse curves. Curve “A” is a good general-purpose goal.
Curve “C” with increased bass will give more impact on rock
and roll, while “B” would sound more natural for symphonic
music. Curve “D” illustrates reduced roll-off in the mids and
highs.
The OEQ-1 is deliberately restricted to 9dB of boost or cut
per band. This is meant to discourage attempts to correct
large system response problems with the equalizer. System
response errors greater than about 6dB over a span of an
octave of more should be corrected elsewhere in the system,
by correcting speaker or amplifier problems. Excessive use
of equalization is likely to overdrive amplifiers, speakers, or
other components.
INPUT AND OUTPUT LEVELS
The OEQ-1 is designed to be used at preamp-output levels
only (500 to 750 mVRMS). Higher input levels may overload
the circuitry and must be attenuated. The OEQ-1 is designed
to have a gain of one (output equal to input) when all
potentiometers are centered.
DEFEAT SWITCH
The Defeat Switch completely disconnects all electronics in
the signal path and connects the input directly to the output.
