This volume control method of the relay + resistor array is a very good audio volume control method in the HIFI audio industry. This product is one of our audiophile products independently developed. There is no impact on sound quality and hearing caused by the contact resistance and sliding noise of the potentiometer and the imbalance of the two connections, and there is no sound stain caused by the digital potentiometer. This relay array volume control board has an immediate effect on sound upgrade and sound quality improvement.
 

Works voltage: AC110V or 220V available

LED Display: Red characters
 

Size: 215mm*310mm*65mm (W*D*H)


Volume board resistance : default is 50K  ( we also can provide 10K  20K  100K  250K for choose)


Note: if  you want change the resistance  Please must send message to us to confirm. or will send the default 50K type,  thanks
 
 

   
This volume controller supports one set of RCA input and one set of RCA output,        one set of XLR input and one set of XLR output.

 
RCA takes the hot end of XLR directly, without independent switching, without conversion, so it only supports RCA in RCA out, XLR in XLR out, XLR in RCA out, RCA in and XLR out are not supported, and two audio sources cannot be connected at the same time.


Features: Pure resistance circuit, fixed input resistance, no popping sound, encoder + MCU control data, no sound level jump.




package include:  Finished  Balanced remote volume controller   X 1
 
                               Remote    X 1  ( no battery)


No AC power cable included.
