4-Channel Power Amplifier for Touring and Installations

With 5,000 W across four channels in a single rack space at a mere 7.4kg/16.3lbs weight, the M50Q is equally versatile in touring and permanently installed racks. Legendary sound quality deriving from Powersoft′s patented technologies, and outstandingly high efficiency are making the M50Q the leader in its class. Optimized for mid-sized sound systems and 4Ω loads, it is a fantastic value, practically as well as commercially.

In use worldwide by leading touring and event sound companies, Powersoft amplifiers are preferred among the top ranking system designers, sound engineers, and contractors for providing reliable premier-grade power and headroom in the smallest possible package size. Maximum efficiency warrants minimum current draw, heat dissipation and power consumption, resulting in ′green′ products, saving the user a substantial amount of money over time.

The M50Q is also available with on-board DSP and Ethernet interface. While the high-performance DSP with FIR/IIR filters is hidden inside and safe against accidental or intentional tampering, monitoring of vital system and amplifier data can be done via Armonía Pro Audio Suite™ software, the same user interface on the same network as for all Powersoft amplifiers. Locally, the M50Q DSP+ETH lets the user access up to four presets per pushbutton on the rear panel.
