Featured Multichannel mono amps?

[RobGMN Premium Member]

I keep hearing about "multichannel" mono amps (mono amps with multiple outputs), which really seems to be a contradiction of words, if ever there was one.
I've also heard talk of a monoblock car amp that can bridged.

The circuit symbol for an op amp shows one output channel and one input. Something like this:

No monoblock amp I have ever seen can be bridged to itself to make more power.

Anyone ever heard of these unicorns?
Anyone have proof of their existence?

There are dual mono amps around
But that's simply 2 mono amps in 1 chassis like the
Genesis series 3 dual mono
Or the ground zero ultra a2

You cannot bridge a mono amp to itself.

The very word, bridge, indicates the connection of two sides. You cannot bridge two full-bridge amplifiers, as they are internally "bridged" mono amplifiers.

Technically, multi-channel all-room or home theater amps can be called multi-channel mono amps since each channel can have a separate input and output capability.

Yes, I am interested where one might hear of a mono amp being bridged to itself to make more power.

I did find some cool schematics though.

This is only viable if every channel in that case has it's own power supply.

Well this went far.

So, multiple monoblock amps in a single box, like Dox says.

Anyone know of a monoblock car amp that can be bridged to itself for more power?
How would I wire this one to do it?

Each symbol for an amp in that diagram has a single output.

I'm trying to find the unicorn circuit symbol of a mono amp that has multiple unique outputs, not a single output connected to 2, 5, 30 terminals.

If I connect 15 Elac Debut speakers to one output/channel of my home amp (let's say the "left" one), it does not mean the amp now has 15 "left" outputs. It is still one output, distributed across 15 speakers, all playing the same thing.

Mono and stereo signals are created
During the music production process

As you all already know mono is no left and right separation

What exactly would be the purpose of bridging a mono amp? For more power?
1 option is get a bigger amp
Another option is to lower impedance of the speaker if the amp can handle it

Even a stereo amplifier can play a mono signal

Let's get the question in context...

This reply

From this thread:

Double negative and postive outputs?! Plesse help...

I have been gone from car audio for a good 10 years and recently decided to get back into it. As I'm building my first new system I noticed almost all new amps have double outputs now... my question is, can I just ignore 1 set of them if I'm using a mono Amp for 2 subs? I'm trying to do a...

That's why Rob is asking

It simply because although everyone in that thread knew what the OP asked and Rob was completely lost babbling about Pyramid type crap

Bridging is the joining "bridging" of the two items, amps, circuits, if you will. What you're asking here is what a multi-channel amp essentially does: combine internal circuits to make one more powerful output. 2 to 1, 4 to 2, 8 to 4, etc.

AS for the mono-stereo thing, not even relevant except to provide one or the other type of end-use result.

50 different channels combined to one is still a mono signal in the end, 50 mono signals separated to 50 outputs is still a mono signal out x 50.

I fail to see how, or even fathom why, there would even be a reason for such a circuit.

This is still going on because Rob refuses to admit he didn't understand the OP in the original thread I linked. He's just trying to find anyway to be right in his ridiculous response and now he's hoping someone will bail him out...while moving the goal post at the same time

Rob will argue to no end that because it is a mono amplifier these 50 outputs as anyone on earth would label them, is one output. Or call it a mono output with 50 connections.
