The 039 multichannel power amplifier is available as a 5-channel or a 6-channel version. It can keep supplying high current in a seemingly effortless manner, and can thus easily power loudspeakers with low impedance values and very complex loads. Although 039 is a 6-channel device, it can be bridged for mono operation via an external Y bridge cable, which turns it into a 3-channel amplifier.
