Bridge mono question

[vtwo]

I'm not quite sure how to phrase it, but if you put your poweramp into bridge mono, can you use two outputs (parallel) and the signal would be the same for both cabinets instead of stereo?

Thanks, guys!

NO

You are talking about dual mono. That is when you have a stereo (2 channel) power amp, and are driving the same signal from both channels.

Bridged mono is also using one signal source, but it is combining the two sides of the amp to provide one large power output. You can run more than one cab from this source, as long as you stay within the ohm specs

I realize the difference, don't get me wrong... I was just wondering if a bridged amp could have parallel output.

Thanks for your input. (ha ha )

A bridged amp will generally use the two positive posts on the outputs. I strongly recommend you check the owners manual for information on connection and load recommendations.

your parallel out will most likely be ch.2 in, however this is not driven how you seem to be describing, it is more of a continuation of the instrument signal. in bridge mono, your only driven output is most likely ch.1 out. if you need to add a cab and can add a cab depending on your impedance specs., you could daisy chain the two.
check your impedance!!
+1 on the manual, too!

If you wire two cabs (like normal) to an amp in bridged mode, they will be 180 degrees out of phase. What happens when you flip the bridge switch on an amp is that it inverts one of the channels, so you can run your cab between the hot (red) terminals, and the voltages will be opposite on the two, giving 2x the voltage swing of one channel alone.

So yes, you could do it, but the two cabs would cancel and sound like crap . . . no harm to the amp, though.

Thanks everyone.
