2-Channel Equalizer Amplifier with ALC

SANYO -> Panasonic 

Ordering number:ENN912D

Monolithic Linear IC

LA3220

2-Channel Equalizer Amplifier with ALC

Features

• Dual pre-amp with built-in ALC (pre-amp × 2 + ALC ×

2).

• Due to high gain, recording amp can be formed sepa-

rately (variable monitor possible).

• ALC and direct motor drive obtained through SEPP out-

put stage.

• Good ALC response balance between channels.

• Good reduced voltage characteristic.

• Excellent channel separation.

• Quick stabilization during power supply input.
