the same frequency.

221R Two-channel VHF receiver:
The 221R contains two VHF receivers operating on different frequencies. This allows single or simultaneous
use of two transmitters. The receiver features two 1/4-inch output jacks and two volume adjustments - one for
each channel.
(1) Power/Receiving LED
When the receiver is plugged in, both the A and B Power/Receiving LEDs will turn RED. When one or both
of the transmitters is turned on and are within reception range of the receiver the A and/or B Power/Receiving
LEDs will turn from RED to GREEN indicating that the transmitter(s) signal is being received.
(2) Antennas
Extend the antennas fully vertical for best reception. When not in use, lower the antennas and put them in their
holders to avoid damage.
(3) 12 Volt Input
Plug the supplied AC adaptor into the 12-volt input on the receiver then into a 110-120 VAC electrical outlet.
Use only the adaptor supplied (BC-26U) as other adaptors may damage the receiver.
(4) Output Adjustment
Rotate this knob clockwise to increase, or counter-clockwise to decrease the volume level. Please note that
the 221R has two output adjustments, one for Ch.A and one for Ch.B
