New project : R-2R Attenuator With Remote Control V2
 
2 Attachment(s)
What I Share here is my Remote Volume Control KIT V2.

This is a assembled volume controller with 4 sources selector based on high quality Panasonic TQ2-5V relays.

8 Bits conrol provides 256 STEP variation, with the selected useful 67 STEPs, this attenuator can be adjust from -48 dB to 0 o dB (with a infinite load).
Comparing to my VOL V1, this new version is more friendly to listening.

hi I also want a "balanced" type of kit (+1 extra main board?).

Please tell me how are you blocking zipper noise? Relays arent fast enough to switch at given zero crossing time afaik.
