Hi Sachu, I have a CNC in my second workshop system, however to to the position of the speakers, I cannot balance the system with the gain dip-switches. Is it possible to put a variable resistor in there place, as is done with the AD797 MC phono amp.

Cheers

Hi Derek
You can use a variable resister for gain there. There are total 4 gain resisters 2x100R and 2X150R.
If you decrease 150R to 100R or even lover you can get additional 2-3db of gain, increase them to 200 R or more would decrease the gain. I would suggest to use some kind of connectors to swap resisters.

Regards
Sachin
