question about remote knob

[Team Nemesis-DJ]

u dont need it...i kind of wish jacob gets rid of that and the bass boost totally....kuz i notice some folks use it and they wonder why there subs are frying...lol....

80

hmm get rid of the bass boost remote thingy and bass boost and add more capacitors on the board in its place...hmmm not a bad idea

...ive wanted both gone since day one ...but you can't ,i see ppl all the time freaking out about the remote gain knob<always asking does it have the BASS knob with it ...LOLZ> ...i havent and wont use them in my set ups ,but thats just me ... Edited October 15, 2009 by Team Nemesis-DJ

please tell me you guys read my follow up... the remote helps a lot in bass race or if i want to go from max spl or turn it down for a little more SQ or when my parents are in the car so they dont bitch at me.

i agree about not needing the bass boost. i dont have a use for it either. but this isnt about "what you like/dont like about the amp".

or you can also get a gain knob that you could wire it from your RCA's..

something like this..i think its better.im have one been using it for the past 2 years and still works great..

don't use it!

tests have been done and you get less output when it is plugged in.

on the 3000d you get about 500-700 watts less

Where did these results come from?

thats crazy how much power you lose

but this remote IS a gain knob. no need for the other remote.

oh my god... did everyone skip over my testing? i found out why they had that power loss.

1) You don't lose power -- the knob drops some RCA voltage as it has a resistance. Therefore you must adjust the gain up slightly to compensate and power will again be identical.

2) The knob reduces gain from the position it is set at the amplifier -- that is it. It is a variable resistor and can only cut signal.

3) It is NOT A BASS BOOST KNOB.

4) We have been reducing the amount of bass boost on the amps... most now feature a 6 dB bass boost vs. the 18 dB they used to have. Occasionally a boost is useful with ridiculously low output voltage head units where even maxing out the gain won't get you any output.

thanks jacob. that's exactly what my testing showed me.

i also notices that if i turn the remote up to say, 8 clicks, i got 73v. but if i turn it DOWN to that same 8 click point i got 78v.

I discovered this years ago playing around on a test bench I had set up before getting into the industry. I made a little variable resistor board wired in line with the RCA cables -- it would reach a point where it was the loudest and then start decreasing again. I can only imagine due to a more ideal impedance match with the source unit.

yeah. your getting the full amount of power without loosing nothing. like the bass knob that comes with the amp. as you stated.

just set your gains, wire this knob and you wont have any problems such as clipping..just use it when you want some bass or for spl comps etc..
