    QUICK START INSTALLATION If you connect lower impedance speakers, the amplifier may overheat and shutdown. DO NOT BLOCK THE VENTILATION PORTS. The M•800 draws its ventilation air in from the front and out through the side panels. It needs plenty of fresh air to stay cool. CONNECTIONS AND SETTINGS 1.

  • Page 10: Feature Descriptions

    FEATURE DESCRIPTIONS LET’S TWIST A GAIN GAIN/dB These are completely independent volume controls for each channel. Instead of having an arbitary scale, they are carefully calibrated: • The inner ring graphic is labeled in dB, though this indicates the amplifier’s voltage gain, think of it as increasing decibels from off to 28.

  • Page 11: Meters

    METERS The meters indicate the output level in decibels referenced 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 –...

  • Page 13: Input

    If you’re using low imped- ance loads at high power levels, we recommend that you use the binding post speaker outputs rather than the 1/4" TS jacks. Al- though 1/4" jacks and plugs are convenient and easy to use, they are not designed to handle high-level currents.

  • Page 17: Limiter

    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 there to protect your speakers from the effects of clipping. Its effect is virtually transparent, meaning you probably won’t even notice any audible difference.

  • Page 18: General Precautions

    GENERAL PRECAUTIONS RACK MOUNTING The M•800 amp requires two rack space units (2U = 3.5"). It also requires 16.25" depth inside the rack, including the rear supports. When designing your rack, put the heavier items at the bottom and the lighter items to- ward the top.

    (mixing console, equalizer, etc.) and the balanced inputs to the amplifier. If you’re using the unbalanced inputs, use a high-quality 2-conductor shielded cable. Your Mackie Dealer can recommend a suitable cable for your application. OUTPUT WIRING Use heavy gauge, stranded wire for connect- ing speakers to the M•800 amplifier’s...

  • Page 22: Appendix B: Technical Information

    APPENDIX B: Technical Information SPEAKER IMPEDANCES A speaker’s impedance varies with fre- quency. For example, it may be 4 ohms at 500Hz, and 6 ohms at 120Hz. What you need to know is the average (or nominal) impedance across the speaker’s frequency range. This will be printed somewhere on the cabinet, or in the specification section of the missing manual.
