We appreciate your vote of confidence bottom line is the M-Series amplifiers achieve some of for the folks in Woodinville who specialize in awesome the lowest distortion numbers in the business without and affordable professional audio designs. resorting to substantial amounts of negative feedback. • That’s Not All!

READ THIS PAGE!! • The screw terminal inputs are wired as indicated: hot (+), cold (–), and ground (GND). Even if you’re one of those people who never read manuals, all we ask 7.

15. For quieter listening, it is preferable to adjust the amplifier’s gain controls rather than the source signal’s output level (unless you have the source’s control all the way up!). Other Nuggets of Wisdom • For optimum sonic performance, the channel and main mix faders on your mixer should be set near the “U” (unity gain) markings. Then adjust the amplifier’s gain control to attain the desired volume through the loudspeakers. • Never plug amplifier outputs into anything except speakers

Dual-Channel Connection The Channel 1 Speakon connector has the added feature of providing both speaker outputs on a single connector. This allows you to use a single cable to carry both channels from the amplifier to the speakers. Refer to the hookup diagram on page 7 for a typical applica- tion using the dual-channel connection. Many speakers with Speakon connectors provide an Input connector and a “Thru” connector for connecting a second speaker in parallel. You can use the Thru con- nec
