LA3220
Overview
The LA3220 is a 2ch-low-noise equalizer amplifier with ALC for radio cassette recorders.
Features
Dual pre-amp with built-in ALC (pre-amp × 2 + ALC × 2).
Due to high gain, recording amp can be formed separately (variable monitor possible).
ALC and direct motor drive obtained through SEPP output stage.
Good ALC response balance between channels.
Good reduced voltage characteristic.
Excellent channel separation.
Quick stabilization during power supply input.
