Stand alone channel balance control?

[JoeDJ]

What is the best way to add some sort of balance control to a 2 channel stereo amp/system that does not have one?

I just want to be able to cut one channel or the other on ocasion and most times both channels wiil be at their max.
So, a seperate control for each channel would do it.

A L pad attenuator for each channel would provide what you need. 50k each channel will give the volume range adjustment.

I assume that would be on each channel's input..........
I happen to have two 8 ohm 50w L-pads on hand gathering dust.... would they work in the input of each channel?

Hi JoeDJ

Yes I was referring to the input being attenuated, however The 8 ohm 50w Pads could be put to good use to provide the volume adjustment you require on the speakers rather than the input. Recycle Reuse Great !!

These are the ones I have...
L-Pad 50W Mono 1" Shaft 8 Ohm 260-255
I would prefer to to put them on the input. Would that be OK?

Would the 8 ohm impedance efffect the input in any way?

Would a pot be better on the inputs?
What about this?

Hi
No, will not work properly because input impedance/ output impedance at line level is quite different to that of the amplifier/ speaker output. The L pad you show, is a wire wound element that suits 8 ohm speaker use.

Best to get the part you need for the purpose required.
