Designed to allow the use of two VHF microphones simultaneously, the 221R Discrete Two-Channel VHF Receiver has 2 complete receiver sets built into one case, each operating on a different frequency. With Power (red) to Receiving (green) LEDs, and two ¼" output jacks with independent volume adjustments.

The 221R will work flawlessly with the Azden 31LT, 31HT and 31XT VHF Performance Series transmitters. Please be sure your transmitter and receiver operate on the same frequency. For example, if you order the 221R(A1/A3), you need to order an A1 and an A3 frequency transmitter, for example a 31HT(A1) and a 31LT(A3).

Azden 221R VHF Wireless Receiver Key Features

Discrete Two-Channel Receiver

Designed to allow the use of two VHF microphones simultaneously, the 221R Discrete Two-Channel VHF Receiver has 2 complete receiver sets built into one case, each operating on a different frequency. 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.

Power/Receiving LED Indicator

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.

Peak LED Indicator

This indicator lights when the receiver's input level from the transmitter exceeds unity.

12V DC Input, Supplied AC Adapter

Plug the supplied AC adapter into the 12 volt input on the receiver then into a 110-120V AC electrical outlet.
