MC601 power output

Run a mono signal to both amps and they should read the same.  If they don’t, the meter may need calibrating.  We’re the monoblocks purchased new or used?

Make sure to switch both to balance XLR or RCA inputs 

there’s a switch buttons at the back 

Tried all that stuff. Still an issue.

Will take them in and get them calibrated.

Thanks for all the replies,

When you changed inputs was it same channel or same amp putting out less power?

Same amp. Going in for calibration. No difference in sound. And the meter on the  amp showing higher power output did not go to zero at rest.
