Hi there!

We are using I-Tech 4000 amplifiers in bridge mode.

It seems that the voltage and peak power limiters are only working on the IQwic screen (we see the shadow of the fader moving) but with no effect on the output of the amplifier.

In stereo mode both limiters work fine.

Any idea about that problem?

Thanks

In Bridge Mono Mode the amplifier is setup as one big Mono block amplifier with oneside going positive and the other side going negative at the same time. Both sides of the amplifier are fed and controlled from the channel 1 processing chain while in this mode.

Thanks for your answer.

We already knew how an amplifier is working in bridge mode.

The limiters are just not working the way they should be.

A voltage or power limiter applied to the input 1 of an I-Tech 4000 in bridge mode is not limiting the output at all.

Can you test it on your side and give us your results?

Please be advise that on the software screen display it seems to work just fine, but there is no limiting at the output of the amplifier.

Thanks!

The issue of limiters not working in Bridge-Mono mode has been confirmed and we are working on a resolution.
