MC624 Monitor Controller / Re: No function of -12db over inputs ans outputs

« on: February 17, 2025, 10:42:32 AM »

My studio amps never have volume control.  Quad 405, Bryston B4, and my Hypex, I always use the monitor controller for level control 

Thanks, nice clean sounding unit.

Thanks for the test method.  We are a db between in and out.  I'm sure lowest attenuation will be fine for mixing.  Could it be possible to add an additional Pad if needed.

Thanks for explaining the functions. 

Listening to a loud source, "Mastered Music," I find it to be 14db louder than some of my lowest listening levels when set to the maximum attenuation of -63. 

If I pull my DAW fader down an additional 42db then the signal is inaudible.

Understood on the attenuation.   

When I run a tone into the input of the MC624 and back into my DAW I observe the following.

-63 on MC624 set to -63db db on daw meter.  A 1db increase is observed until -5.  After this, there are no more level increases or relay clicks. 

Thanks

Finished the build and everything sounds great.  I'm just having two issue. 

The attenuation of inputs and outputs.  I can add +12db of gain on all i/o but I don't get any attenuation.  Also at -63 I have level louder than I would expect. 

The relays are not clicking,  Which relays and IC deal with the i/p and o/p attenuation? 

thanks
