Equalizer
The Meyer Sound CP-10S is a ten-band stereo
parametric equalizer featuring five bands of fully
parametric equalization per channel, with an
additional high and low shelving cut filter for
each channel. Any frequency between 60 Hz and
6 kHz can be controlled by two equalization
circuits per channel. Frequencies below 60 Hz
and above 6 kHz are controlled by one equaliza-
tion circuit and one shelving cut filter per chan-
nel.
The front panel occupies 3
1
/
2
inches of rack
space, and individual In/Out switches are in-
cluded for each band of equalization. There are
separate, screwdriver-adjustable Center Fre-
quency, Bandwidth and Boost/Cut controls. The
complementary phase circuitry assures con-
trolled phase distortion, even at extreme set-
tings, and the dynamic range of the instrument
is better than 110 dB under operating condi-
tions.
The front panel is easily removed, and each of
the fourteen equalization circuits is mounted on
its own gold-socketed removable printed circuit
board, guaranteeing ease of service. LEDs indi-
cate power status and clip levels. Signal pro-
cessing is initiated by a relay that closes only
when the power supplies have stabilized. In the
event of AC failure, the unit automatically
switches to hardwire bypass.
