General Description
Technical Specifications
This system is ideal for hands-free vocal and speech applications, and is particularly well-suited for on-stage performers. The systems include either an
ME 3 omni-directional lavalier microphone or an ME 4 cardioid lavalier microphone. The extremely small SK 300 G3 bodypack transmitter and EM 300
G3 rack-mountable receiver each features 20 frequency banks with 6 user
banks and 24 directly accessible frequency presets. Each system is ready for
immediate use.

Architect and Engineering Specifications
The wireless microphone system shall feature a true-diversity receiver with 42 MHz of available tuning bandwidth with a total
of 1,680 frequencies accessible in 25 kHz steps. The wireless microphone receiver must feature one Balanced XLR output with a
max. output of +18 dBu, and one unbalanced ¼” output with a max. output of +12 dBu. The wireless microphone receiver must
feature two BNC antenna inputs, one for each receiver module in the true diversity system. The wireless microphone receiver must
feature a backlit display that displays AF and RF levels, battery telemetry from the transmitter, operating frequency, and diversity
switching information. The wireless microphone receiver must feature an automatic frequency scanning function that utilizes
eight banks of pre-coordinated frequencies that are free of intermodulation interference. The wireless microphone receiver must
also feature a user bank in order to store user defined frequencies. The wireless microphone transmitter must operate on two
1.5V AA battery cells. The wireless microphone transmitter must have access to 1,680 frequencies tuned in 25 kHz steps across a
defined 42 MHz bandwidth. The wireless microphone transmitter must feature a backlit display that displays frequency information, AF level, battery level. The wireless microphone transmitter must transmit a pilot-tone squelch. The wireless microphone
transmitter must have a specified RF output power of 30mW. The wireless microphone receiver must accept 12V DC power via
BNC antenna inputs.
