The transmitters provide 3072 frequencies selectable in 25 or 100 kHz steps across more than 75 MHz of tuning range in each band.

To meet the demand for both extended operating range and extended battery life, the transmitters offer selectable output power at 25, 50 and 100 mW. With higher power output, the operating range is improved at the expense of battery life. When range is not an issue, the power can be reduced to extend the battery life. The transmitters will tune across three standard blocks to make it easy to find clear operating frequencies.

The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed ahead of the first mic preamp to protect the entire audio chain from overload. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no distortion.

A special vent in the battery door prevents a vacuum from being created inside the transmitter when it is moved from a warm, damp environment and stored in a cool place. The vent allows air to pass as the pressure equalizes, but blocks the passage of moisture.
