4 M-Series M-Series Introduction Thank you for choosing a Mackie high-efficiency power amplifier . W e appreciate your vote of confidence for the folks in W oodinville who specialize in awesome and affordable professional audio designs.
5 Owner’ s Manual Owner’ s Manual Getting Started READ THIS P AGE!! Even if you’re one of those people who never read manuals, all we ask is that you read this page now befor e you begin using the M-Series power amplifier .
6 M-Series M-Series 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!).
7 Owner’ s Manual Owner’ s Manual Hookup Diagrams M-Series Pow er Amplifier: Biamp Connection Using Built-in X-ov er This drawing shows a typical stereo hookup, connecting two speakers to the Speakon® outputs. The Amp Mode switch is set to STEREO, and the X-over switches are set to FULL.

10 M-Series M-Series M-Series Features Front Panel Much of the front panel of the M-Series amplifiers is comprised of ventilation slots for expelling warm air from the inside of the amplifier . Be sure to leave space in front of the amplifier for proper ventilation to occur .
11 Owner’ s Manual Owner’ s Manual 3 . P R O T E C T I nd ic a t o r If the PROTECT LEDs are on, the amplifier’ s output section has shut down. That, of course, means you won’t hear anything until you rectify the situation. Thr ee things can cause the PROTECT circuit to engage: 1.
12 M-Series M-Series Be Aware: If the OVER TEMP LED comes on fr e- quently , something is overworking the amplifier or it’ s not properly ventilated. Look at each of the “extreme conditions” described above and try to determine what is causing the amplifier to overheat.
13 Owner’ s Manual Owner’ s Manual See “Output Wiring” on page 18 for mor e info on mak- ing the speaker output connections. 8 . A M P M O D E This three-way switch, along with the X-OVER switches, determines what kind of amplifier you want the M-Series amplifier to be (or not to be — what was the question?).
14 M-Series M-Series ing. The Thru jacks are wir ed straight from the XLR and TRS INPUT s — ther e is no electronic circuitry between — so the signal going into the amp is exactly the same as the signal coming out of the Thru jacks.
15 Owner’ s Manual Owner’ s Manual 1 4 . P o w e r R e c e p t a c l e This is a standard 3-prong IEC power connector . Connect the detachable linecord (included in the box with your M-Series ampl.
16 M-Series M-Series General Precautions and Considerations AC Power Considerations Be sure the amplifier is plugged into an outlet that is able to supply the correct voltage specified for your model. If the line voltage should drop below about 97% of the rated voltage, the amplifier will no longer be able to supply rated power .
17 Owner’ s Manual Owner’ s Manual AC Power Distribution In order to minimize ground loops, the safety grounds for all the outlets should be connected to a common (“star”) grounding point, and the distance between the outlets and the common grounding point should be as short as possible.
18 M-Series M-Series Unbalanced TS (tip-sleeve) signals can be accom- modated via the combination jack. Make sure the cord terminates with a TS plug (like a guitar plug), or if it’s a TRS plug (like a headphone plug), make sure the ring is tied to the shield, preferably at the source.
19 Owner’ s Manual Owner’ s Manual B r i d g e M o d e Binding Posts When using the binding posts in bridge mode, connect the positive side of the speaker cable to the CHANNEL 1 red (+) binding post, and connect the negative side of the speaker cable to the CHANNEL 2 red (+) bind- ing post.
20 M-Series M-Series 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.
21 Owner’ s Manual Owner’ s Manual Appendix A: Ser vice Information • Is the SHORT [4] LED lit? T urn the POWER off, check the speaker connections and make sure that there ar e no strands of wire shorting across the speaker terminals. • Is the OVER TEMP [5] LED lit? Make sur e there is cool air available at the rear of the amplifier .
