A cool way to add sonic quality and punch to your 5.1 or 7.1 receiver if you have pre-outs.
Most of the latest A/V receivers can send processed audio data to a D-Sonic M3a amplifier for a dramatic increase in power and quality.
This puts the power where it belongs – the front 3 channels which require 75% of the total amplifier reserves. This frees up your receiver amplifier to provide far more power to your side and rear channels.
