Hi everyone,
I hope you can help me understand my Marantz MM500 amplifier -- there is very little information online about this amp so I am posting some details here, including a block diagram.
I would like to know if I can use this as a 4-channel amp -- hooking the 4th speaker to the rear speaker outputs at the L CH and R gnd?
Its a multichannel amp from the ProLogic days. It has 4 RCA inputs (Front L, Front R, Center and Rear), and it has 5 speaker outputs (Front L+R, center, and rear L+R). The rear L+R run off one channel.
Here are its specs:
front ..... 75W/ch rms into 8 ohm
center ... 80W rms into 8 ohm
rear ...... 40W/ch rms into 4 ohm
I'm guessing that the front L+R channels are better quality. They use an AN7062 chip while the center and rear use STK401 chips. I'm also guessing they used the STK401 chips so the rear was 4ohm stable -- then they ran 2x 8-ohm speakers in parallel to present a 4 ohm load. I don't know why the output of the rear channel doesn't increase compared to the center channel at 8 ohms.
Thanks for your help!
Dave
