Crown vz3600 amp into JBL Speaker
Posted 07 February 2013 - 02:30 PM
Ok to put the 3600vz (bridged mono) amp with a JBL S128s bass speaker ?
I know JBL recommend a 2000w amp into its 1600w (average power rating),but is this ok to run the 3600vz on 50% maybe ?

I would suggest to limit the amps power going into the speaker even further so you wouldn't Experiance power compression, limit the amps continuous power to about 40% of the speakers continuous power rating.

or in other words, how would i work out how far to turn the AMP volume knobs before the amp started to destroy the speaker ?

Any way, you start with putting the gain as far as you need and turning it back down if you hear distortion, so the best thing for you to do if you don't want to get a limiter or a DSP containing a limiter, is to keep your ears open for that distortion and turn the gain of the problematic channel on the mixer down a bit, till the distortion is gone and then just a bit more. If it's only one player causing all the distortion it might be worth your while to put a compressor on this specific channel before going into the mixer, this way if he plays in the correct level then his signal stays the way he wanted it to sound, and if he is driving you rig into distortion he gets compressed and you stay in control.

The 'gain' control usually refers to a control that will amplify the signal applied; For example, the gain control of the input circuitry of a mixer can amplify the signal to more than 60dB.
The 'attenuator' control fixes the maximum level of the sound to the next circuit when fully open and will attenuate the signal to the desired level.

First the term, I know it's not that accurate but I did take the "gain knobs" name from the XTi manual. I would call it the sensitivity control or something like that.
As to the "attenuator" operation you described, it would have to have some kind of a limiter action to be able to not let the signal get above a certain level. I'm not sure how it works in the digital era of amps and I know you know what is going on from the inside of the amp much more then I do but from an end user point of view I always new it to be working the way I explained in the prior post, will try later to find posts on other forums that support what I say and if I can't I will be very happy to be corrected.
