Audison HV Sedici

Amp powers up and idles at 20 amps of current .

Amp works besides the idle current is way to high .

Any ideas on this ? Do I need to adjust the bias or idle current ?

 

[Perry Babin]

That would be the first thing I'd try.

Do you know if the one in red or the one in blis is the bias adjustment?

And on the 2nd pic is that pot for the idle adjustment?

 

[Perry Babin]

I don't know but I'd suspect that it's the one nearest the bias transistor.

Thanks Perry ,

I adjusted the bias and amp idles perfectly now

 

[Perry Babin]

This may be an amp that's designed to run at high bias. Were both channels causing precisely 1/2 of the overcurrent?

I'd do some research on whether this is a high bias amp or not. The only reason that I'm suggesting it is because I know nothing about these amps.

Ask the owner if the amp has run hot at idle for the entire time that he's owned it.

It’s supposed to idle at 2.6 amps as factory specs .

It was idling at 10 amps .

Only 1 channel was causing the bias issue other channel was fine I set them both the same but only 1 channel was Causing the issue .

I tried adjusting them while watching the current draw if you set it fully counter clockwise the amp will draw excessive current so I set 1 channel and it took care of the issue then reset the other channel and it’s right about 2.5 amps of current draw per manufacturer specs

Hello, I need your help - how to adjust the variable resistors on the PWM boards and on the protection/clip detection boards. Thank you!
