The 311DR contains two separate receivers, each operating on the same frequency. The transmitter's output is constantly monitored by a microprocessor which switches automatically to the receiver with the strongest RF input. This allows wireless performance that is virtually drop-out free, even under the most adverse conditions. The receiver features a 1/4" output jack and volume adjustment.
The Azden 31XT Plug-In Transmitter is a unique transmitter that snaps onto your favorite wired handheld microphone (any metal-body with XLR connector) turning it into a wireless microphone.
