1 gain knob for 2 amps, non-strapped????

[jonny101abc 10+ year member]

can i control 2 amps with only 1 bass knob on non-strapped amps?

I've never used a gain knob before

i have 2 crescendo 3kwp's and i want to use the gain knob, but i don't want to use for each amp.

can i use a jack splitter or something along those lines? or do i have to use a knob for each amp?

Thanks, John

no, you can't do what you are describing. if you use splitter the amps will see the wrong resistance. characterize the resistance of the bass knob the amps come with, and buy a potentiometer with the same specs, but two swipes. Look on Digikey.com for potentiometers with two separate swipes. you'll need to know the resistance range. for this, you'll need to take the bass knob apart and meter the terminals. or call the amp manufacturer, talk to tech support engineers, and ask them what the range is.

so you can have one knob to control both equally, but it'll be custom as described above.

You need a PAC LC-1 (~$15 shipped on ebay). It is a potentiometer ("gain knob") that will control the voltage through the RCA cable between the deck and the amp. That, and another set of short RCAs is all you need.

While I'm at it I'd like to say that everyone should have an LC-1. At $15ish bucks it's worth trying.

You talking about a gain knob or a bass boost knob? If you want the latter, just don't use one.
