| Designed to allow the use of two VHF plug-in
transmitters simultaneously the 221XT 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
31XT transmiiter uses a single "AA" battery.
