Are Birthsheet Specs done with the Gain Setting maxed out?

I'm just curious as to where abouts my T1001bd is getting its full 1485 watts...

I don't think that it would be very good to make any judgements based on a clipped signal.

It's more of a question related to bench testing protocol, rather than towards my own fine tuning.

I thought rockford provided bench tests with thier product. But I see your question more clearly now.

You want to test the amplifier with maximum undistorted output...maybe you could get away with running with the gains cranked depending on the input signal. I wouldn't recommend it. But if you're benching it with an o'scope (I would assume), doesn't really matter as the scope will tell you exactly where to stop //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

i think he is asking wether rockford benched his amp with the gains cranked or not

I would assume to meet CEA certification it's the max undistorted output...that would be the logical assumption.

But who knows //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

Silent Bob is saying it depends on the input voltage. I mean Jack Frost.

I thought CEA was only @ 4 ohms. But then again, I don't know much.

Yep

 

[johnson 10+ year member]

Yep

Then you dont really know what gain is there for.

Then enlighten me oh wise one....

Yep

The answer is no, because an amplifier can reach full output with the gain set to minimum if the input voltage is high enough.

What Jack is saying is that the birthsheet figure is rated output into Xohm with X voltage input from the power source (probably 14.4V for CEA-2006). Whether the gain is set to maximum, minimum or anywhere in between depends on what the preamp input voltage is from the source unit.

Hmmm....
