I just bought a Mch 3SE-C7, I using my Oppo 983 running directly into my Nuforce amp (atm I'm using the digital volume control on the oppo)....On first power up, I let the amp do its self test diagnostic, I waited till only the Nuforce logo was lit up, then I hit ON and 2 on the remote (selecting L and R channels), then the Leds indicated 3 in 5 were in operation yet, channels 3 and 5 are lit in green. Does green not indicate "no signal detected per the manual? Yet, Im getting sound out of these channels... Anyone have any info on this?
