Description
EQUALIZER INPUT
Pin 17 is the equalizer amplifier input pin. A
signal which has passed through a 4.5 MHz
trap is input through pin 17 and is output
through pin 19.
.
The input level of pin 17 is 1.5 Vp-p. This
is amplified 3 dB to 2 Vp-p by the
equalizer amplifier.
18
EQUALIZER FILTER
Pin 18 is the equalizer pin. The equalizer
amplifier is of the voltage follower type with
a voltage gain of 3 dB. To correct the
frequency characteristics, connect LCR
externally.
The operating characteristics are as follows:

EQUALIZER
OUTPUT
Pin 19 is the equalizer amplifier output pin.
This output has a built-in low-impedance
drive circuit.
