Is anyone aware of a wall mounted volume control that has a smooth rotary dial? As it is it seems every one that I have found is a 'notch' type rotary dial, such that there are 10 discrete volume levels etc, rather than a traditional smooth rolling type. Thanks!

They are notched for a reason. The notches are where the volume pot makes contact with the rotary pin, giving you the volume you want.

You could try a slider type of volume control.

Generally they step because they are NOT simple potentiometers as might be used for the volume control on a electronic device but are instead multiple position switches selecting between taps on a transformer.

These devices allow you to connect multiple sets of speakers to an amplifier and insure that amplifier sees a suitable impedance.

If you only need to control the volume when connecting a single set of speakers to an amplifier there is a device called an L-Pad which is usually not stepped.

I would assume that if manufactorers are able to produce sliding volume controls, the same scheme could be adopted to a rotary dial?? If not, how does a sliding control work.....Maybe varying the load position on the windings? Seems like that could be done on a rotary dial also..

Well I only checked in a few places for slider types but the ones I found were stepped as well.

But there is so much out there who knows what you might be able to find.

I prefer the stepped ones myself - easier to return to a known setting.
