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.

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.
