volume control

[nicg]

I am in the process of installing tower speakers and looking for ideas on volume controll. I am running four tower speakers (from 4-channel amp) and four in-boat speakers (from head unit).I would like to be able to control volume on both sets without spending a fortune ($$WS-420$$) so i was thinking of hooking up a pac-lc1 in between the amp and headunit for the tower speakers.as far as i know that would give me ability to adjust the volume on my tower speakers,but i would also like to be able to seperately adjust the volume on my in-boat speakers without fading or balancing.

basically i would like to have the option to turn up the tower speakers and down the in-boat speakers or vise-versa.
any help would be appreciated

NICG,

You're never going to be able to fully isolate both tower and in-boat zones until you add a 2-channel amplifier to drive the four in-boat speakers.

At that point you can use your fader (front/in-boat)(rear/tower) to dial up, down or blend individual zones. Two redundant LC-1s will provide the same function but conveniently located and quickly accessable without going into the source unit's menu (a pain on some models).

The scheme as you've described it will only fade away from a single pair of in-boat speakers since you're using all four internal channels of the source unit which are driven by the same preamp section as your RCA preouts. Even an EQ will not resolve the issue without another amplifier.

A switch on one pair of in-board speakers would be a clumsy method one step closer to total isolation and avoid another amplifier.
