8 Vocal Zapper
Before proceeding with testing and calibration, thoroughly check the bottom of
the circuit board for solder bridges and cold solder joints. Clip off any compo-
nent leads that extend beyond the height of the rubber feet. Recheck parts
placement and values. Once satisfied that all is well, snap two fresh 9v.
transistor radio type batteries into the battery clips with the power off.
By far the easiest way to use the Vocal Zapper is to connect it between a CD
player and amplifier as shown in the illustration below. Alternately, it may be
connected between the preamp and power amp of nonintegrated systems.
The Vocal Zapper can also be connected to a stereo system through the TAPE
OUT and TAPE MONITOR jacks, as shown below. Note that the stereo's TAPE
MON button must be in the IN position to put the Zapper into the stereo signal
path.
After hooking the Zapper into your system, turn on the power switch of the
Zapper and all other components and start playing the program material you
will be working with. With S1 on the Vocal Zapper in the NORMAL mode (right
most position when viewing the panel from the front) you should hear the
program material, but in mono; and you may notice a slight drop in overall
volume level, which can be compensated for with the stereo system's volume
control.
