Hi.
Hope everyone is managing OK through this crazy time.
Helping a friend build a switch box for his system.
Here is the challenge...
There are two sources in his system. A turntable, and everything else...
He has two phono stages. One Tube with volume control (EAR834P) and a solid state one.
He wants to be able to switch between the two pending music played. This part is simple...
As the solid state Phono Stage is fed into a different preamp, and the EAR834P is bypassing it, they need to be isolated from each other. Still simple.
Both the the signal paths go through a High Pass filter in all cases to the Amp.
The signal is also split prior to the high pass from both sources and is sent to the Subwoofer.
The signal paths here also need to be separated from each other.
Getting more complicated.
What I am hoping to do is do all this switching with a single rotary switch, and put the switching as well as the high pass filter in a single box solution.
Too many wires running around the way it sits now...
I've attempted to draw a breakdown of how the flow needs to happen. Hope it makes sense...
Option 1 is using the EAR834P, Option 2 is running it through the SS Phone Stage.
How can I achieve this with a single rotary switch? Don't want to have three separate switches for him to have to flip back and forth.
Thanks!!!

There are 3 pole four throw switches for RCA jacks available for about $12 on ebay, also some discount stores. They are called TV source selectors. There is red, right, white, left, and yellow, TV. The TV band one works fine on audio. I'm using one to switch sources to my TV room amp, sometimes TV tuner, sometimes streaming audio from the PC.
The name today is composite video selector. AV Switch Box Composite Selector 4 Port RCA Audio Video 4 In 1 Out To TV 44276899111 | eBay
$14 today.
use the yellow for the sub woofer. Drawing one would be first button pushed in, drawing 2 would be second button pushed in.
The limit on RCA cables is about 12' or they start picking up AM/CB/fire/police/ham radio, also hum. If you go farther than that you need to go to tip ring shaft (TRS) twisted pair cables. The cheapest device I know that would do that with some quality would be a Peavey PV6 mixer. I use a PV8 usb in my living room where it cut hum about 3 db from my RCA cable installation, which is 12'. I'd already killed the radio by putting disk caps across my amp input on the point to point board, which you probably don't want to do since yours is not a diy product.
The PV6 has high/middle/low filters on most channels. Switching would be by turning gain knobs on that. There was a new one on ebay for $149 four months ago when I bought my PV8 usb for $199. used stereo Peavey mixers go for ~$50 but usually you have to replace the master volume pot and the power supply. Don't buy a mono one, they are everywhere & come up first on ebay because they are cheap. Alesis & yamaha mixers have some fans, no personal experience. Yamahas are expensive even used.

That would be good to know!
But, I was really hoping to find out what kid of rotary switch I could/should use for this?
