Tabletop testing a Hypex NC400

Hey everyone,

I have a common question with the NC400 and after reading the manual and searching the forum I haven't found a direct answer.

I've received my NC400 amp from Europe but the enclosures were not available so I'm waiting... While I'm waiting, I'd like to make sure that the amps are working OK with the rest of my gear and make sure I wired everything up correctly.

I've connected all the pins, powered it up, and the red LED's appear to be all on. But I can't get any sound. I can hear a very very quiet playback through the compression horn on the speaker if I put my ear up to it.

I'm guessing this is because the amps are in standby due to nAMPON you're meant to ground to the enclosure.

Is there anywhere I can temporary connect nAMPON and get the amps out of standby without an enclosure?

I've soldered on XLR inputs with white, blue, and ground to the appropriate pins. I'm using an XLR to RCA adapter cable for input from a DAC with volume at 20%.
 
Actually, it was very simple. There's no need for any special grounds to get the amps out of standby. Simply use the "amp enable" pins on the connection pcb or the psu.

Looks like something isn't quite wired right on mine though. I'll take that to another thread...
