Stupid question about bridging.

Post by MarkL » Sat Jun 08, 2024 11:23 am

I have an old IP-4C.

I want to bridge it to a single 4ohm load.

Looking at the instruction manual, it shows both outs, bridged mode, to a minimum 4 ohm load.

My stupid question is if I can just use one output on the power amp to get the 500 watts at 4ohm or if I have to populate both outputs, and if I have to populate both outputs, will it internally "wire" the two 8 ohm drivers in parallel to a 4ohm load?

Page 9 in the manual covers Bridge mode operation. In basic terms you put the amp in bridge mode. You then use the RED binding post from channels 1 and 2. Channel A's Red binding post is positive, Channel B's Red binding post is neg. It would be better if you let people know what you have for speakers and what they have for inputs (where the speaker cable plugs in) If your speakers have 2 1/4 inch inputs and each speaker is rated for 8 ohms then you could go in one, then out that one to the other one. The 2 combined, so long as the input jacks on the first speaker is setup for parallel, will give the amp a 4 ohm load. Again it would be better to know what you are going to use for speakers.

Thank you. I see. I am going into 2 8ohm drivers currently wired in serial to a single 4ohm plug. I guess what I was unclear on was the how to hook up from said bridged setup. So apparently I use a banana clip from red A and red B?

2 8 ohm speakers, wired in "Series" will give the amp a 16 ohm nominal load. 2 8 ohm speakers wired in parallel will give the amp a 4 ohm load.
You can use banana clips or turn the red post out and put bare wire through the post holes and tighten them back up.

You probably meant "daisy-chained" wiring, and not serial - as Dookie noted, a serial connection would be a 16 ohm load. Daisy-chaining is parallel wiring, and if you plug in the cable from the amp to the first speaker then connect a second cable from the first speaker to the second speaker, that is a parallel connection (and is called daisy-chaining). Another way to have a parallel connection is to connect both speakers directly to the amp. You can stack banana clips to accomplish this, and is more efficient for power delivery as well as better for maintaining dampening factor.
