HIGH_LEVEL_FOUR_CHANNEL_MIXER

Published:2009/6/24 2:07:00 Author:May | From:SeekIC

To provide good signal－to－noise ratio，this four channel mixer amplifier controls the signal levels after the amplifiers，and then mixes them to offer a combined output. The circuit works with any 50 ohm to 50 K dynamic microphone but not with crystal or ceramic mikes because the IC input impedance is low. Note that all four circuits are identical but that only one is shown complete.
