amp: from bridged to unbridged

[SlowcarIX]

going from bridged to unbridged, keeping the same gain/sub, will the sound level decrease?

thx!

It has for me.

[treitz3]

Yes/probably. It did with my gear.

thx!In theory the only difference should be the maximum power available so using a single channel (unbridged) it will reach its clipping point sooner .

Slowcar, how do you like your D-Sonic 2500-7? How is the sound quality and the reliablilty? Does it run as cool as you expected an ICEpower amp to be?

Thanks.

In theory the only difference should be the maximum power available so using a single channel (unbridged) it will reach its clipping point sooner .It may vary by amp them. I find myself having to adjust the gain after playing with bridged and unbridged modes on my Mac MC-126.

The biggest difference is the load. Bridged usually means you're driving the channels harder(2 or 4 ohm versus 8 ohm), therefore, you often get free power at the expense of the amp heating more.

Depends on the amp. Some adjust the gain down when you engage the mono switch; others just just set both inputs to the same channel and reverse the polarity on one -which will give you twice the voltage.

It may vary by amp then. I find myself having to adjust the gain after playing with bridged and unbridged modes on my Mac MC-126.Yeah ,looks like your Mac doesn't change the relative gain differences between the bridged/unbridged setting.Some manufactures like Bryston (atleast in their ST and SST 2 channel models) do change the gain appropriately to match the two.
This is nice if you are running a multi amp setup consisting of bridged and unbridged units as the gains will be matched.

they are very neutral sounding amps...7 monoblocks in one chasis, any coloration pretty much comes from the speakers. I leave mine on 24/7 in the everwarm state with a 12V trigger. This is my 2nd d-sonic amp and no issues so far...shorted the outputs many times, no harm done.

i leave the cover off...the 1000ASP blocks run much warmer than the 500ASPs...to a point where they are too hot to touch after a movie at very loud levels with 4ohm speakers.

check them out!

ok...i went from bridged to unbridged on the face 1200 sub amp and w/o changing the sub/gain, there was a very significant drop in output - the speakers were overpowering the sub and had to redo a calibration.
