Volume regulator question

**zvi** · 03-18-2004, 12:11 AM

will it work, if i put volume regulator between PC and AMP? just a regular variable resistor (one per channel - I have 2 channels). will it affect on quality of the sound, or will it work at all?

it will work.. but hurt quality. make sure the resistor oms isnt to high or you wont get sound out.. .

im trying to make a 4 chanel volum control. useing one pot and 4 op amps.. havent got all the detals worked out yet

how should I calculate how many ohms resistor should I have? in order to have the whole volume range (from 0% to 100%) spread to the whole spin range of the regulator

The way sound control resistors work is one end is connected to the ground, other to the signal and the mid-point is your output.

you'v gota find out what V out put you have to get the right ohm or you'll have to big or no dead spot
