Advice Needed - Adding 'Master' Volume Control Knob to 2015 Lync with Zone Control

[JOPETE1]

I'm hoping someone out there has some guidance for me on this, but I have a 2015 G21 with a Linc 2.0/Polk UM1 system outfitted with Zone Control (includes 4 Polk Amps). Nothing has been changed from factory setup.

My goal is to add an analog, Master Volume Control knob, or even better, add the Roswell Dual Zone Volume Control with one knob as the Master Volume and the outer knob as the Tower Volume...

I got the wiring diagram from Nautique (attached) and it appears as though the audio signals aren't really exposed to RCA jacks until AFTER the Zone Control module... which doesn't really enable a Master Volume Control... (ie. I'd either have to remove the Zone Control or add 4 separate volume knobs... I think)

Does anyone have experience with this or suggestions on how to hook up a master volume control with this setup?

Thanks!

The roswell dual zone will not function as a master system wide volume and then single zone. It has a single input that is split to each knob's circuit. Its only go to be a 2 zone pre-amp controller. With 4 amps, you can 4 on one zone and leave the other unused, 3 and 1 or 2 and 2.

Are you trying to do away with the polk/link interface? Sounds like you are looking for the Wet Sounds WS-220 https://wetsounds.com/pages/products/WS-220BT.html

Depending on your amp setup, I add these direct to the amps. http://www.jlaudio.ca/hd-rlc-marine-...essories-98118
One for inside speakers and one for the tower. works perfect.

I cannot seem to download a decent resolution of that wiring diagram. Any chance you could PM it to me or post a link?

Exactly what I used except one for tower speakers and one for subs. Gives complete control of system from helm...

The JL unit is specific to the JL amps and will not work on the OP's 4 Polk Audio amps.
