Default Single volume control for 5 TA2024's

Hello everyone,

I'm working on a project where I'm using 5 TA2024 modules, there are 10 separate audio channels in total. The only thing I'm stuck with is the volume control, I can't seem to find an easy and cost-efficient solution for controlling the volume of all 10 channels with one knob. Does anyone has a solution?

At first I agreed with Arty, but after much "there's gotta be a way" pondering, hold on a sec.

A "distribution board" is the opposite of a "mixer board." That is, there are as many outputs as needed (if you build your own), each with its own volume control, and a master volume control.

Having had this brainstorm I was designing a distribution board in my head when I looked on Google, and to my surprise there really is such a thing commercially.

But you'd have to clarify your needs. Especially, how many different inputs? Would each self-powered speaker (I suppose) be playing the same material, or different material?

OR if it's just one audio signal being fed to 5 different locations, and you don't need 5 volume controls, then all you need is what's called a distribution amplifier (actually a distribution preamp).

If you do not have any solution, then go for the lightspeed attenuator

There are a number of good chip volume controls that are used in AVRs, if 0.25 - 0.5 dB increments are acceptable. You may need to control them with a microprocessor - something like a Rasberry Pi.

he would like to controll the volume of 10 different channels with a single knob.
so a distribution amplifier is not going to cut it.

Not a distribution amp, but a distribution board. Sure it could be just the ticket--though you might have to cascade them to a ridiculous degree, depending on both the board and the material.

Seems not to matter much in any case, since the OP apparently has moved on.
