M61529FP
Audio Signal Processor with Surround
REJ03F0010-0100Z
Rev.1.00
Sep.04.2003
Description
M61529FP is the semiconductor integrated circuit for Home Audio. M61529FP includes 2ch electronic volume,
Tone control, 4 Input Selector, Bass Boost, REC output and Mic Mixing. This IC is suitable for Mini Component.
A difference in M61529FP and M61519FP has just changed Tone Input ATT from 0/–13dB to 0/–8.2dB.
Features
• 2ch Master Volume (L,R Independent Control)
Main Volume : 0dB to –76dB (2dB or 4dB step), –∞
Trim Volume : 0dB to –15dB (1dB step)
*Total level is fixed at –87dB, on condition that the total level of Trim and Master volume is under “–87dB”.
• Tone Control (Bass/Mid/Treble)
±8dB (2dB step)
• 4 Input Selector with Mute
• Surround Function
• Vocal Cut Function
• Bass Boost Function
• L+R Output for Spectrum Analysis Display
• L+R Output for Subwoofer
• MIC Mixing Function
• 2 REC output with mute
• Input ATT
: –5/0/+3.5dB
• Tone Input ATT
: 0/–8.2dB
• External Input ATT : +3/0/–3/–6dB
Application
Mini/Micro Component, Radio-Cassette Recorder with CD Player, etc.
