The Monitor controller is working and the REM624 makes changes to the MC, but the display on the REM624 is not right. The dB is wrong and the LEDs on the buttons are lit incorrectly.
The firmware in the two units are different versions: v1.7 and v1.8.
I bought the two together as a package but I'm wondering if the different firmware is causing the problem?

It is not the firmware. The V1.8 chip goes in the REM624.
the display on the REM624 is not right
Can you describe it or share a photo?

I had a IC reversed and it is working now. Thanks
After using this for a few days, I have a few questions / comments:
1) is there a way to adjust the brightness of the number display? I would like to make it dimmer in the studio. I suppose the 1k5 resistor networks could be increased but wanted to check if there were a simpler option.
2) I expected 'L only' or 'R only' combined with mono would play L (or R) through both speakers, but it does not. Looking at the schematic I would expect it would?
3) When listening at low volume the dim function doesn't reduce the volume as much as it should. Is this because total attenuation is maximum at -63dB? So with a -18dB dim setting, it will be incomplete when the volume is lower than -45dB? Curious if there is any adjustment for this? If not, I can bring down the volume on each of my speaker pairs.

1. The most obvious sulution is to replace the resistor networks RN8 to RN13 by higher value networks.
Another more complex solution would be to cut the +12V track to each display and replace by a lower voltage created with a regulator from the +12V.
2. The Mute Left/Right + Mono function sends the mono signal to either the left or right speaker.
3. You are correct. The Dim function cannot pass the -63dB.
