TM FAST RECOVERY SERIES HIGH CURRENT POWER AMPLIFIERS The world is full of amplifiers that do one thing - amplify audio signals. But at Mackie Designs, we've always put out the extra effort to provide more quality and more features than our competitors while maintaining a comparable (or lower) price. The FR Series™ power amplifiers are designed to perform reliably under the most adverse conditions, and we've added a bundle of extra features, so you don't have to put out the extra bucks to buy a bunch of add-ons or plug-ins to make your sound system do what you want it to do. Meticulous Detail Perhaps the most important aspect of the FR Series amplifiers is the attention to detail in the design of the electronic architecture. We have incorporated a number of unique properties including Fast Recovery, sustained high-current output capability, high voltage and current slew rate, and defeatable clipping eliminator, to ensure that the output of the amplifier is virtually distortion-free. FEATURES s Fast Recovery design for improved transient response and recovery from clipping s Rack-mountable (2U) with rear support rails for extra support s Separate left and right detented gain controls, calibrated in both dB and volts s Balanced XLR and 1/4" TRS input jacks s Balanced XLR thru jacks s Heavy-duty binding post output jacks in parallel with: M•1200 - 1/4" TS output jacks M•1400 - Speakon® output jacks s 6 LED metering including Signal Present and Overload s Separate L/R Protect LEDs indicate the following protection conditions: 1) Automatic turn-on delay to prevent potentially damaging thumps and pops from reaching your speakers 2) Short-circuit protect with separate L/R indicating LEDs 3) Thermal protect with combined Ch1 and 2 Cold and Hot indicating LEDs s SCR Crowbar DC offset protect MORE INFORMATION M•1200/M•1400 ARCHITECTS & ENGINEERS SPECIFICATIONS s "IN YOUR FACE" SOUND REINFORCEMENT & RECORDING BROCHURE s Low-cut filter with variable frequency control (Off - 170Hz) s Subsonic stabilization eliminates ultra-lowfrequency noise caused by microphone handling, stage rumble s Constant directivity horn compensation with variable high-frequency boost control (2kHz to 6kHz) s Amp Mode switch for Stereo, Mono, or Bridge modes s Limiter to eliminate clipping in both channels s Subwoofer mode switch with dual-frequency select (63Hz/125Hz) s T-Design Constant Gradient Cooling Tunnel uses two short tunnels instead of one long tunnel for improved cooling efficiency and output device reliability s Dual-speed cooling fan s Toroidal transformer for reduced EMI emissions ® 1
