Questions about Bass Knob

[Raisedin305 5,000+ posts]

OK so I purchased two D5000s off of Shane (HCCAFAN) and I know each comes with it's own bass knob. I was wondering though, is bass knob just another word for BASS BOOST? I know I shouldn't use bass boost and never will. Are they the same thing?

It should just be a remote gain control.

So it's just used to control the gain? I shouldn't really mess with it then? When im setting my gains with the DMM do I have the adjust it with the bass knob(s) too?

If you are goin to use the bass knob, make sure the knob is all the way up when u r equilizing ur gains on the amp, that way u will never exceed the gains required.

OK thanks. From there I can control the subs directly? I can shut the bass on and off from the knob instead of the HU?

The remote on many amplifiers acts as a remote gain. BUT, with it turned all the way up, you will be at the point to which you set your gains origonally. If you set it at X, and have the remote all th way up, your gain will affectively be at X, if you have it all the way down, the gain will be lower.

It is like this on some amps, I do now know about ALLL though.

OK I understand how it works now. Thanks guys

yea, basically the knob will work to ur advantage or how it is supose to work. u can control ur bass effectively withought destroying any of ur equipment, its a lot easier than to mess with ur HU when u need to turn it down right away let say u see a cop.

I never use them. That's what the "sub-out" on your HU is for...

X2, i rather use my knob then go through the menus on my HU

All I do is push one time, and turn...

There are basically two types of remote volume control.

Most common one is passive variable L-Pad. Meaning, these are merely a passive resistor controlling the preamp output. So, the system has zero gain.

Joust like a typical L-pad with a volume control for your speakers.

The 2nd type has a gain. It uses a "VCA" voltage Controlled Amplifier". Now, this topology has a gain feature built-in. This particular type uses or should say, it parallels the gain on the amp.

So, it's like having a double gain control and can be more difficult to adjust. The other by-product is that if you "pinch" the wires, you could short the entire preamp section of your amp.

A 3rd by-product is that since this wire is "hot", you can also run into noise being injected into the wire. It's barely a 22ga straight-stranded wire without shielding.

A boost can be a benefit if one understands the relationship between the woofer's resistance vs. amplifiers output.

A typical woofer will have an impedance (ohms) rise around 35~50Hz. As much as 20 Ohms.

So, if you have a woofer with an impedance rise of 10 Ohms at 45Hz, and your amps rated for 300watts, at 45Hz, you will merely get 30 watts out of the amp.

In this situation, it's best to have a boost at 45Hz and boost 10dB to compensate for the impedance rise (loss) in the woofer.

Let’s remember, an amp will only produce based on the impedance (load) it sees from the woofer.
