Hi all, can anyone point me in the right direction for a good quality line level wall mounted volume control, it will be used between a audio source (rca output on a separate amp) and some icepowered speakers.
I found this one, but they dont make it anymore.

i suppose you could just use a 10k potmeter, and build a wall mount yourself. I guess it just takes a piece of wood and a nice potmeter knob.🙂
wall mounted means it's remote from the source and remote from the receiver.
That in turn means long cables.
You will need low source impedance at the source and at the vol pot to ensure the cables do not affect the treble.
You will also need some noise/interference attenuation and this is easier if your impedances are lower, rather than higher. Better still to use balanced impedance connection from source to vol pot and from vol pot to receiver.

That product was just a 100K stereo volume pot on a wall-plate. And a PCB so connection from pot to RCA jacks was streamlined for production.
If you are handy with metal-whacking you can mount a pot in a plate yourself. Wire RCA jacks, or the cables themselves, directly to the pot. If you are un-handy, get a basic switch cover, pot, and some 3/8" washers to make-up the difference between round bushing and square switch-hole. Get a knob big enough to cover the nuts and washers. Steel switchplates will be more robust than plastic.
Yes, running line-level through a 100K pot is begging for hum and other noise induced from nearby wiring. Perhaps consider moving to the 21st century. The volume controller itself can be with the other gear, the human interface a radio remote. That is apparently a standard item now. Yes, the remote will get lost. Look for something that boasts it can work with "any remote".

I executed a project such as this in a six floor building. There were local amps driving a set of speakers in various sections of the building.
I used a balanced line driver circuit to run a balanced signal throughout the building and in each section, tapped the signal to a balanced receiver, followed by a volume pot, amp and speakers.

Thanks for your input guys, I'm doing a cable run of 2m from reciever to "pot" and approx. 10m from "pot" to powered speakers. Will this distance cause issues?
it depends if it's a balanced signal. for unbalanced rca i believe about 5 meters of cable is about the maximum distance before you start getting noise problems. With a balanced signal(xlr or trs jack) this distance is nothing.
Thanks for that Dennis, The icepower powered speakers will have a balanced signal input. I'm still coming to terms with the whole balanced input thing. As I dont understand it too well, I'm installing ghent audios balanced input modules for my icepower 125asx2 se modules.
> Will this distance cause issues?
It Depends.
I have run unbalanced several hundred feet, in benign rooms (often churches with almost no electric wiring) or with aggressively low impedance 440 Ohms).
At 100K I have had trouble a few feet across a messy (electrically) workbench.
You could mock it up outside the wall. Run a long RCA cable, a vol-pot, and more RCA cable. Listen to the amp as you try the pot at half-level or lower, and press the cables against the wall where they will run. If you get a hum/buzz, it will probably be a bit worse when the audio cable is a few inches closer to whatever causes hum/buzz.
This assumes plain plasterboard or wood walls. If your house runs to metal walls(!), out-of-wall will not be valid.

Up the way is already over 1.2m,Thanks for your input guys, I'm doing a cable run of 2m from reciever to "pot" and approx. 10m from "pot" to powered speakers. Will this distance cause issues?
how do you arrive at 2m from source to wall mounted attenuator?
That's the approximate distance the wall mounted "pot" will be from its input source. the input source is in the ceiling.
