	The LX-75 Series are professional grade FM transmitters operating in the commercial FM broadcast band (88.1 - 107.5MHz) that can be used in a wide variety of applications in sound re-enforcement, hearing assistance, information and short range broadcasting. Their outstanding RF and audio performances, solidity, reliability and versatility make the LX-75 Series stand out from conventional FM broadcasting systems. The LX-75 Series feature our latest technology innovations called DAFP and DAPP technologies (Direct Access Frequency Programming) (Direct Access Power Programming). These new digital technologies allow the end user to program the frequency and the RF power without any manual tuning inside the unit. The LX-75 Series are currently the best stable, trouble-free FM transmitters available on the market; thanks to the new auto-compensation circuitry that will assure optimum linearity on a temperature range of - 50°C to +50°C (-58°F to +122°F). The stereo generator section of the LX-75SM feature a full digital circuitry that allows a stereo separation of over 40dB. Near CD sound quality broadcasting is now a reality with the LX-75 Series. The LX-75 Series are offered in three different audio configurations for the most demanding plug & play applications. Applications for the LX-75 Series are endless but here are some popular ones: Multi-lingual conference, Drive-In theatres, cinemas, museums, Concerts, Sound linking and Theatrical arts.....

LX-75 Series Configuration

Front & Back Panel Description

POWER: Indicates that the AC power has been activated.
OVER: Indicates over modulation (100% and more).
LINE LEVEL: Controls the audio level that is applied to the line inputs jack.
MIC./BAL. LEVEL: Controls the audio level that is applied to the Mic/Bal input jack.
MIC./BAL. INPUT: The audio input (low impedance balanced input).
AC input: This is where you plug the AC adaptor (furnished with the transmitter).
AC power switch: Turn the power unit on or off.
RF POWER: Power programming switch.
BB: When activated, the bass boost switch enables a circuitry that will produce a 6dB gain from 20Hz to 150Hz.
ST: When activated, the stereo switch enables a digital circuitry that will produce stereo broadcasting.
FREQUENCY SELECT: Frequency programming switch
LINE INPUTS: The audio inputs signals (high impedance unbalanced inputs).
The transmitting telescopic antenna.
