b2 audio 4 channel
With evolution things change & adaptation is the norm.
The new Quattro shows that a compact footprint is not equal to less muscle.
Instead of switching to class D full range, we chose the evolution, class H. This enables us to make an efficient amplifier with the qualities of a class A/B, but where the power output is superior even with smaller footprints.
So the Quattro has shed some weight and is even sleeker than before. But even though the width is more than 2" less than prior, we were able to increase performance with 10%.
Also the appearance has been brushed up, now the RCA inputs are upgraded to mini Tiffany, which enables better and more secure connections.
For the audio purists that want to keep things simple, there is an added feature. The amplifier will change its circuit from a 4 ch to a hybrid 4 ch active. That way you can have your tweeters on one pair of channels, the mid ranges on the other. Might not sound new? Well you will only need to run 1 set of RCA inputs to the amp and you only need to use 1 gain and 1 setting for the crossover, since the high pass setting is also determining the low pass crossover settings.
But fear not, it can still be used as an ordinary 4 ch with full range on all or low pass with bass remote on channel 3/4.
Welcome to the Active Evolution of the Quattro.
