Description
The M61523FP is a semiconductor integrated circuit using the SCF technology. This IC is no need external parts of
Tone and Loudness block. External components for pop-noise were reduced by built-in the offset reduction circuit
and several pop-noise improvement circuit.
Features
• Dual source type (Main/Sub) Input selector
Input of single 3ch and the differential 1ch.
• Input gain amp.
Main selector and Sub selector can do the setting of gain independently
0dB to +14dB/1dBstep, +14dB to +20dB/2dB step
• Built-in 2ch master volume with soft-changing circuit for pop-noize
+6dB to –80dB/1dBstep, –∞dB (L and R independence control)
• FADER
Front, Rear : 0dB to –48dB/2dB step, –56, –∞dB
(Front and Rear independence control, L and R are controlled at the same time)
Non FADER : –26dB to +12dB/2dB step, –∞dB
