Designed to allow the use of two VHF handheld
mircophone/transmitters simultaneously the 221HT system has 2
complete receiver sets built into one case. With Power (red) to
receiving (green) A & B LEDs and two 1/4" output jacks with
independent volume adjustments.
The 31HT microphone/transmiiter uses a single "AA"
battery.
