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”.
