Wow.

I feel dumb after reading what has been spewed....

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.

Assuming the source always sent 1V, then yes, it would alwyas be at "full volume". You do know the source would not always send 1V, right?

Due to your extreme n00b status or due to some of the extreme ignorance present?

Well, not "always"... it would of course be proportionate to the true "source" being the CD itself.

The cd player also has a gain in there somewhere of course.

You can use a volume control AS a gain... but the gain still remains a volume control.

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?

because noise is always present. The higher voltage just boosts the signal enough above the noise floor to 'mask' the noise.
Dave Navone/RC even said it themselves that you should look into a deck with atleast 2v or more.

And I agree, and with most decks, you need at least 4v.

Turning the gain up will amplify any line noise, and you can turn down the volume on that line noise by turning the gain down.

w00t.

actually it's the impendance you should look for. the lower the better

Total awe.

OK, when you said maximum were you reffering to maximum sensitivity or maximum numerical value on the setting?

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.

It doesn't matter what "WE " know.......Mr. Potts is correct. There are 1000 professionals out there (including the very folks that make his equipment) and "WE" are all wrong. We should be taking lessons from Mr. Potts. David Navone and Richard Clark will be VERY impressed. I can't believe all these people were lying to me during training. Mark Eldridge is gonna hear about his incompetant lessons he's been giving all of us in his class. Oh well..back to the drawing boards. I'll be sure to send a link of this to a few of my sponsors and see their take on it also. Appearantly, we've all been taught incorrectly.

dam skippy!

Just because you set the gain to one thing and use the head unit to control volume doesnt make the gain any less of a volume control... you very well could set the head unit to a certain level and use the gain on the amp to control volume... in which case, the head unit has a "gain" setting, and the amp has a "volume control".

 

[xmax-1 10+ year member]

i've never seen an amp w/ "0" gain.i've only seen a range of 9v-2v on amps. so no matter how low you set the gain, there'll be voltage, therefore watts.

That is correct.

You could...

But we come back to the point that Nick (and everyone else that has a clue in this thread) had - that although they may have that function in some remote, isolated case that nobody uses in the real world, talking about them like that is grounds to be laughed at. Part of the reason why no-one outside of a few "select" online forums (where the average intelligence is low enough to support your claims) takes you seriously...

Normal usage does matter, contrary to whatever you may think in that deluded little reality of yours.
