Continuing the Crown reputation for high qualityand reliability, the FM100 achieves versatility withoutcompromising operating parameters.The FM100 is available in three configurations: The FM100E is abasic exciter for broadcasting composite audio and SCA signals.For a transmitter with high quality stereo generation, audioprocessing and peak-limiting, choose the FM100T. For operationas a translator, the FM100R includes a high sensitivity receiverwith composite output to drive the exciter. The receiver includesautomatic gain control in the mixer stage to maintain maximumsignal-to-noise ratio and selectable band-pass ceramic filters foradjacent channel rejection.The unique Automatic Level Compensation (ALC) circuit protectsthe FM100 from voltage, temperature, and VSWR variations. Ifoperating parameters move outside the safe operating range oftransmitter components, the ALC automatically reduces outputpower to safe limits until normal conditions are restored. Asummary of fault conditions and all metered conditions areavailable at the rear panel for remote monitoring. Key internaloperating parameters are displayed on a front panel digital meterfor rapid verification of the transmitter condition.Reliable operation is a major design criterion in the FM100. WithTeflon circuit boards and copper heat spreaders in the RF chain,the unit functions with less heat and improved life span. A powersupply, with switching voltage and power regulators for AC or DCoperation, provides stability, flexibility, and reliability even whenprimary power fluctuates.Call Us!Call us, visit our web site or send us e-mail for more informationabout the versatile transmitters from Crown Broadcast.
