Quattro The Active Evolution

The Quattro 4ch in it’s 4th. version can be configured to run in active mode.
A single set of RCA will provide signal to all 4ch, while a single gain makes it simple to eliminate passive crossovers for your component speakers.
The Quattro’s built in high pass crossovers ranges from 50 Hz all the way to 5 KHz, with a unique tweeter level gain adjustment if ran in active mode.

Fear not, the B2 audio Quattro will still work as an ordinary 4 x 100 watt amplifier, but its small footprint is possible due to a class H design.
This will increase the efficiency in the power supply, making it more powerful while maintaining the SQ with an analog audio output section.
To provide plenty of headroom with dynamics, the Quattro features a massive number of small capacitators with low internal resistance for optimized current flow.
Should the 4 x 100 watts  not be enough (most likely not), the Quattro can be bridged at 4 ohm delivering 2 x 300 watts, more than enough for any Pro audio or component system speaker. Be more than the ordinary, B2.

*In order to get the full power output of the amplifier, it is crucial that your electical system is correctly (over) dimensioned. Failure to upgrading will constrain the power output & lower the efficiency which can cause damage to the amplifier & void the warranty, this also includes ohm loads below of what is written in the manual. Do take your time and read the manual thoroughly before installing!
