800 W POWER AMPLIFIER
Four-Channel Power Amplifier
with Crossover

AV quattro is a four-channel amplifier which can work in four, three, two channel mode,
delivering 800 W (RMS) power total. It is designed in order to handle complex configurations
as front/rear and multi-channel systems.Inputs and ARTTM ensure interfacing with every type of source;
up to 24 dB/Oct. slope crossovers allow to build front-rear, front-sub or multi-amplified systems always
having a non-filtered output signal to expand the system. AV quattro also allows you to replace the analog
input board with the digital one (AV bit IN).
