DIGITAL SOUND CONTROLLER WITH SRSsurround

M62430FP

DESCRIPTION

The M62430FP is dual channel sound volume/quality. The volume section is designed to the 2 channel either simultaneously or respectively in steps of 1dB. It incorporates the ladder resistance mechanism to reduce noise and distortion. The tone control section is capable of controlling the tone within ±10dB in steps of 2dB. The M62430FP is built in Sound Retrieval System.

FEATURES

• Electric volume (MAIN and REC Volume )

•Volume level........... 0dB ~ -79dB,- ∞dB (1dB / step)

• Tone control

•Bass / Mid / Treble , 0dB ~ ±10dB(2dB / step)

•Bass boost +10dB(ON / OFF)

• SRS Surround

• Space/Center volume ... 0dB ~ -∞dB

• 4 Output ports

• Built-in microcomputer interface circuit controlled by 16-bit serial data.
