Mono Vs Dual Mono Amplifier

What the difference bewteen a monophonic amplifier and a dual mono one?

To improve audio quality, a Brand can choose to make an amplifier with a mono or dual mono design. The same is true for the players, preamplifiers, power amplifiers etc...

The better is the channel separation, the better will be the soundstage. So a mono amplifier will be better than a dual mono, and much more than the simpler designs.

 

No dual mono at all

It is the simpler and cheaper to make for the Brand. It was VERY common. Potentially is the worst sounding.

Here you can't find simmetry, but fortunately it only concerns older products, as long as you are not unlucky to find it even in a recent amp

Partially dual mono

It is just a bit better than the previous type.

Only the output board is dual mono. As you can see there are two symmetrical channels. This board is connected to the speakers connectors. Everything else is in common for the both channels.

The board is one for everything to reduce costs, because it is a cheap amplifier, but you can notice tha part of the ac power section is a dual mono to improve sound quality.

Dual mono

One half of the amplifier is specular to the other one. There is simmetry.

As you can see there is simmetry, anche each channel has a dedicated power supply and boards. At the center there are the inputs. This is the best design for and integrated amplifier,but obviously it costs much more to produce.

This is a TRUE extreme dual mono. Here even the inputs are dual mono! If you check the rear panel, on the left side there are only the left inputs and outputs, and viceversa for the right side! This is truly hiend.

Monophonic

When a "box" contains just one channel. Everything you can see is just for one channel. It is a common design for power amplifiers (the monophonic ones), and it is extremely rare for all the other type of products.

You don't need to see inside, because if you check the connectors, they are just for one channel, so you need two of this products.

Notice

As stated above is valid also for preamplifiers, power amplifiers, cd players, etc etc.
