The bodypack transmitter features 2000 frequencies that are tunable in 25 kHz steps, 20 fixed frequency banks, 32 compatible frequency presets, and 6 user banks with up to 32 user programmable frequencies. The transmitter's menu-driven backlit LCD display shows the current frequency, frequency bank and channel number, metering of AF level, lock status, transmission status, muting function, battery status, and more.
In addition, the operating range is about 330'. This transmitter incorporates a Sennheiser HDX compander system, a defeatable pilot tone squelch, and is equipped with a frequency range from 80 Hz to 18 kHz. Finally, power is supplied by the two included 1.5V AA sized batteries, or by one optional Sennheiser BA 2015 rechargeable accupack. A travel pouch is also included.
