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. ® with Architects and Engineers Specifications FEATURES MORE INFORMATION 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 1/4" TS output jacks s 6 LED metering including Signal Present and Overload s Four levels of protection circuitry 1) Automatic turn-on delay to prevent thumps and pops from reaching your speakers 2) Short-circuit protection with separate L/R indicating LEDs 3) Thermal protection with combined CH1 and CH2 Cold and Hot indicating LEDs 4) SCR Crowbar DC offset protection s Low-cut filter with variable frequency control (Off - 170Hz) s Infrasonic1 stabilization eliminates ultralow-frequency noise caused by microphone handling, stage rumble s Constant directivity horn compensation with variable highfrequency boost control (2kHz to 6kHz) s Amp Mode switch for Stereo, Mono, or Bridge modes s Limiter to eliminate clipping in both channels CHECK OUT OUR WEBSITE WWW.MACKIE.COM s "IN YOUR FACE" ALL PRODUCT BROCHURE s Subwoofer mode switch with dualfrequency 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 1a.k.a.
