4 QUICK ST AR T 6. Determine which AMP MODE is best for your application: • STEREO mode (separate left and right inputs, separate left and right outputs) is the typical setup for amplifying ster eo signals.
5 9. In STEREO and MONO , connect speaker cables to the SPEAKER OUTPUTS , either binding post or 1/4" TS: • The binding posts are wired r ed = positive (+) and black = negative (–) • The 1/4" TS connectors ar e wired tip = positive (+) and sleeve = negative (–) 10.
6 APPLICA TION DIAGRAMS Mackie’s gang of oppr essed illustrator droids have created easy-to-understand diagrams of popular studio and live-sound setups. FEA TURE DESCRIPTIONS: Each and every knob, switch, and connector on the M•800 power amplifier is explained in depth here.

10 Here ar e some more examples of how you might use the GAIN controls: • When you are in a small room wher e loud volume is not requir ed, having the amp gain controls turned fully clockwise would r equire you to keep the mixer faders down exceptionally low .
11 METERS The meters indicate the output level in decibels refer enced to the clipping point of the amplifier . The top LED is labeled OL (short for Overload). If this comes on, the amplifier will start to dis- tort, and the audio signals may “clip”.
12 POWER CORD The M•800 is supplied with a detachable power cord. Make sure the power switch is off before firmly attaching the cord to the ampli- fier . Fit the other end into an AC outlet properly configured for the type of plug on the power cord and for the voltage rating of the amplifier .
13 If you’re using low imped- ance loads at high power levels, we r ecommend that you use the binding post speaker outputs rather than the 1/4" TS jacks. Al- though 1/4" jacks and plugs ar e convenient and easy to use, they are not designed to handle high-level currents.
14 In order to match the output bandwidth with your particular speaker system, the M•800 am- plifier has a tunable LOW CUT FIL TER. The frequencies ar e clearly marked along the knob’s travel: • Fully counterclockwise, the frequency is be- low 10Hz, effectively bypassing the filter .
15 CONST ANT DIRECTIVITY SWITCH If you don’t have constant directivity horns, you can leave this switch OFF . Compression drivers mounted on constant- directivity horns r equir e compensation in the form of a high-frequency boost, with its “knee” set somewhere between 2kHz and 6kHz.
16 AMP MODE This three-way switch determines what kind of amplifier you want the M•800 to be (or not to be — what was the question?) The switch alters the input signal routing within the amplifier . Shipped from the factory , it is set to STEREO , correct for about 90% of appli- cations (hence the TYPICAL indicator near it).
17 LIMITER LIMITER ON (TYPICAL) . This is the normal configuration with protective limiting. LIMITER OFF is without protective limiting. The limiter is not designed to alter your sound — it’s just ther e to protect your speakers from the effects of clipping.
18 GENERAL PRECAUTIONS W ARNING: Bypassing the plug’s ground pin can be dan- gerous. NEVER do it! The AC current demand of an amplifier var - ies depending on several factors, including the crest factor and the duty cycle of the program material.
19 AC Power Distribution The majority of AC outlets encountered in homes and clubs are served by a 240V AC center-tapped service en- trance transformer .
20 • T urn the POWER off, check the speaker connections and make sur e that there ar e no strands of wire shorting across the speaker terminals. • Is the HOT LED lit? Make sur e there is cool air available at the front of the amplifier . Make sure there is room at the sides of the amplifier for warm air to exit.
21 As soon as the music gets loud, the amp shuts down! • Check the M•800’s meters. Be sure that OL is not lighting up frequently or continuously . • Can the amp breathe? The M•800 amps draw their ventilation air in from the front and out through the side panels.
22 APPENDIX B: T echnical Information For example, four 8-ohm speakers, con- nected in parallel, will equal a 2 ohm load (8 / 4 = 2). If the parallel loads aren’t all the same, things gets a little more complicated, but noth- ing that you can’t do with a simple calculator .
