Mackie FR800/FR1400/FR2500 FR Series Owner's Manual - Page 4

FR SERIES AMPLIFIERS Introduction Congratulations on the purchase of your new Mackie power amplifier. Please read these instructions to get the maximum performance from your amplifier, and to keep the owner's manual writer from getting sad. He's been a bit down recently, after his sweetheart in accounting started going out with that amplifier designer, just because he can whisper sweet nothings in Klingon®. The FR series amplifiers are designed for continuous duty in speech, music, and sound reinforcement applications in churches, schools, offices, arenas, hotel meeting rooms, convention centers, recreation facilities and other venues demanding high performance, flexible features, and rugged dependability. A rear panel low-cut switch allows you to remove low frequencies, and a clip-eliminator allows extra protection for your speakers by preventing the amplifier from being overloaded. The amplifier can operate in stereo, dual-mono, or bridged mono. The output connections are Speakons® and binding posts for left, right and bridged mono. The inputs are capable of accepting balanced XLR, 1/4" TRS, or unbalanced 1/4" TS connections from line-level sources. Two front panel level controls allow adjustment of the input signals. The front panel has a rocker power switch with a power LED, and each channel has a signal-present LED and an overload LED. The amplifier output stage is fully protected against permanent damage caused by overloading, shorts, silky boxers, and extreme temperatures. The front panel incorporates holes for rack mounting, where it will take up two rather lovely rack spaces. There are two handles fitted on the front panel for easy transporting.
