PLEASE tell me hes wrong

[Spkrman]

I can set my head unit to volume 20 and *never* touch it.... essentially making it a line driver.

I can then adjust the VOLUME with my amp(s)... making the gain on the amp, DRUMROLL, a volume control.

Yes, the "intended" use of hte gain is to be set somewhere and 100% relative to input voltage.. but, its still a volume control, no matter how you look at it.

Congrats.

Now - do you drive with it like this?

noooooooooooooooo

Should n00blets listen to music with it like this?

noooooooooooooooo

Again - ill education, and mindless bullshit. Your good at it, congrats.

Please exit stage right >...

Btw: Yes if you have a set volume or 'input voltage' on your headunit, you can turn the gain up to match that voltage...which in that particular instance it is a volume knob.

But you are still matching relative voltage, no matter how you look at it.

But guess what... the gain is a volume control.

And yes, sometimes I do that... I set the HU to something, and screw around with the remote gain. Or should I say remote volume control.

A "nooblet" wouldnt be a "nooblet" if he fully understood the purpose of the gain... and tellin him its "not a volume control" is just a cop-out. To fully understand the signal chain is a good thing, and I wish thats how it was taught.

ideal for MAX s/N is max signal w/o distortion.

max gain is horrible in any situation. noise will be present no matter what.

It's not a cop-out particle board boy. It's the way it is.

Go make a thread over on car sound and tell them its a fvcking volume knob.

I don't see people running back to their trunks when they want to turn it up or dBdraggers with their 75 amps turning each and every one of them up when they burp it.

You...hole...back in....now.

How? If the maximum sensitivity on your amplifier is say 5V and your source sends 5V at the desired listening volume, you're using the amplifier at what it was rated at that volume. How is that horrible?

That is 100% not true.

It depends on the amps design... the "max" the gain can be set to may not be the "max" the circuit can boost voltage, but the "max" it can put out before distortion.

I can say, without a doubt, the orion 2500d and kicker zx2500 can see 100% gain and sound the same as they do at 1% gain...

If max gain made for distortion, why can I just turn the volume on the HU up, and the gain on the amp down from full, and do the same exact score?

3:1 gain structure.

admit it, I'm right... go ahead, its ok, you'll live... maybe.

It doesn't matter what "normal" use is (although most anything with remote gain uses the gain as a volume control)... all that matters is the definition, and, its, DRUMMMMMROLLLLLL a volume control.

You are not right - Period. Go ahead, jump on car sound and make a thread...get somebody else with some brains to tell you your wrong.

Have fun with this particle board boy, I can't make the blind see, or the deaf hear. Or the ignorant learn.

Well lets assume the amp will distort no matter what is inputted @ full gain.

Can we also assume this about the head unit @ full volume?

100% depends on design.

Gain = volume control.

Why would I bother?

YOu have already conceded the gain is a volume control, just not in as many words... and, the gain is a volume control, period.

Thanks.

And yes, pboard > you

Scenario:

I run a HT cd player to my zx2500. HT cd player has a voltage output of 1v.

Am I supposed to "set" the zx2500 to 1v? Sure, I could, but in this case it would always be at full volume.

I'd say I would turn the gain up and down to control the volume from the source.

Something that controls volume = volume control.
