This is a reboot of our popular audiophile quality 128 steps balanced in/out volume control board.
The board features :
1. high quality PCB with SMD components already soldered on the board ;
2. Dale non-magnetic resistors as the only resistors on the audio path ;
3. Can be retro-fitted with IR remote motorized potentiometer to become a remote stepped volume control board.
The existing values have an input and output impedance of 47K to 600ohm. This allows the volume control board to be interfaced with most of the signal sources.
Input Impedance : Between 47K to 3K ohm
Supply voltage : AC 12V to 15V or DC +15V to +18V 250mA
