INTRODUCTION Thank you for choosing a Mackie Designs power amplifier! We appreciate your vote of confidence for the folks in Woodinville who specialize in awesome and affordable audio. The Mackie Designs M·1200/M·1400 Power Amplifiers are designed to fulfill the amplification needs of almost any type of application. They boast a wealth of features you'd expect to pay extra for -- like subwoofer filtering, constant directivity equalization, speaker-protecting limiter, and gobs of ultra-clean power, to name a few. Perhaps the most important feature of the FR SeriesTM Power Amplifiers is the attention to detail in every aspect of the design. At Mackie, we know what it takes to be roadworthy. After all, our mixers have traveled all over the world under the worst of conditions, and we've applied what we've learned to the mechanical design of our amplifiers. Roadworthiness is only part of the picture. We know that reliability is paramount to sound reinforcement. That's why we use double-sided thru-hole-plated fiberglass printed circuit boards. That's why our engineers have subjected the amplifier to the most rigorous and punishing tests imaginable, to fine-tune the design and extend its limits beyond those of ordinary amplifiers. Fast Recovery -- where the "FR" comes from -- is more than a buzzword. It is based on real, proven design principles. The result is an amplifier that performs better than conventional designs when presented with adverse conditions. One of the most difficult things for a power amplifier to handle is clipping. Conventional designs use lots of negative feedback to provide stability and lower distortion. When clipping occurs, this "feedback" causes highfrequency sticking, keeping the amplifier "latched" in the clipping state longer than necessary. This results in painfully audible distortion. Our Fast Recovery design eliminates this high-frequency sticking and allows the amplifier to remain stable when powering highly reactive loads at high volume levels. You may wonder why a power amp even needs an owner's manual. After all, you just plug in a few cables and power it up. Well, it's almost that simple. There's just a few things that we'd like you to be aware of, and we'll discuss those right away -- please see the Quick Start on the next page. Then go ahead and read the entire manual. The M·1200/M·1400 amplifiers have a wealth of useful features, and each of them is explained in detail.

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 stereo signals. · MONO mode (sometimes called DualMono mode ­ one mono input, two mono outputs) is for sending a mono signal to two different speaker sets, with separatelyadjustable level controls. · BRIDGE mode (sometimes called Bridged-Mono ­ one mono input, one mono output) uses both sides of the amp to double the power to one speaker set. An M·1200 power amplifier, set to BRIDGE mode, delivers 1200 watts (into 4 ohms). The M·1400 delivers 1260 watts. Garsh! Note: 4 ohms is the minimum impedance you should connect to the amplifier in BRIDGE mode. If you connect a lower impedance load LEDs may in BRIDGE mode, the SHORT light, putting the amplifier into PROTECT mode. switch accordingly. Set the AMP MODE 7. In STEREO mode, connect line-level cables from your signal source to the M·1200/ jacks, either XLR or M·1400's INPUT TRS: · The XLR and TRS inputs for each channel are wired in parallel. · The balanced XLR inputs are wired pin 2 = hot (+), pin 3 = cold (­) and pin 1 = shield (ground). INSTALLATION The M·1200/M·1400 amps can be mounted in any standard rack system (see ), or placed horizontally on a floor or table. The heavier internal components are located towards the front of the chassis to make it easier to hold the amp by its front handles. IMPORTANT: The M·1200/M·1400 amps draw their ventilation air in from the front and out through the side panels. They need plenty of fresh air to stay cool. DO NOT BLOCK THE VENTILATION PORTS (see ).
