3. OP-AMP IC (IC303, IC304, IC305) : NJM4580M
1) Overview
Dual operational amplifier
2) Functions
It amplifies Analog audio signal from D/A Converter IC.
Each associates to and amplifies 2 channels, and then outputs 5.1 Channel to JK300.
(IC303 : Main L.R, IC304 : Surround L.R, IC305 : Center, subwoofer).
cf)
Using 2CH Audio DAC IC (IB02) model outputs 2 Channels to JK101 or JK301 using only OP-AMP IC (IC 303).
