Thank you for purchasing AZDEN’S “PERFORMANCE SERIES” wireless system. This manual covers the 311DRH, 311DR, 221R, 211R and 200R receivers and the 32BT (Lavaliere), 31XT (Plug-in XLR), 31HT (Handheld), 31LT (Lavaliere) and 31IT (Instrument) transmitters. Receiver Descriptions The 311DRH True Diversity VHF Half-Rack Receiver: The 311DRH contains two separate receivers, each operating on the same frequency.
(4) Antenna connections. On the 311DRH the antennas are connector mounted (BNC) so that the supplied antennas can be disconnected and/or remoted using coax cable if needed. (5) 12-Volt Input. Plug the supplied AC adaptor into the 12-volt input on the receiver and then into a 110-120 VAC electrical outlet. Use only the adaptor supplied (BC-26U) as other adaptors may damage the receiver. (6) Output Adjustment. Rotate this knob clockwise to increase, or counter-clockwise to decrease volume level.
The 311DR True Diversity VHF Receiver: The 311DR contains two separate receivers, each operating on the same frequency. The incoming signal is constantly monitored by a diversity circuit, which switches automatically to the receiver with the stronger RF signal. This allows wireless performance that is virtually drop-out free, even under the most adverse conditions. The receiver features a 1/4-inch as well as an XLR output jack and volume adjustment.
(7) Frequency label Indicates what frequency (in MHz) the receiver operates on. The AZDEN transmitter in use must also be on the same frequency. (8) Output (balanced) Using a suitable audio cable (not supplied) connect the XLR connector to the audio output on the receiver, and connect the other end of the cable to the suitable mic/line input of an audio mixer or amplifier. 221R Two-channel VHF receiver: The 221R contains two VHF receivers operating on different frequencies.
(5) Output (unbalanced) Using a suitable audio cable (not supplied), connect the 1/4-inch phone jack end of the audio output on the receiver, and connect the other end of the cable to the mic/line input of an audio mixer or amplifier. Please note that the 221R has two outputs, one for Ch.A and one for Ch.B. (6) Frequency label Indicates what frequencies (in MHz) the receiver operates on. The AZDEN transmitters in use must also be on the same frequency.
(6) Frequency label Indicates what frequency (in MHz) the receiver operates on. The AZDEN transmitter in use must also be on the same frequency. 200R Single channel VHF receiver: The 200R features a 1/4-inch output jack and volume adjustment. (1) Power/Receiving LED When the receiver is plugged in, and the Power button is press IN, the Receiving LED will turn RED.
TRANSMITTER DESCRIPTIONS Model 32BT: Lavalier microphone with body-pack transmitter. Ideal for speaking applications such as Lecturers, Actors, Actresses, etc. Model 31XT: Plug-in XLR transmitter turns any dynamic metal-bodied microphone with XLR output into a wireless microphone. Model 31HT: Handheld microphone with a built-in transmitter. For all vocal applications such as Vocalists, Karaoke Singers, etc. Model 31LT: Lavalier microphone with body-pack transmitter.
(4) Audio Input Level Control Turn clockwise to increase, or counter-clockwise to decrease the input level. A small screwdriver is supplied to make adjustments. The level control is factory-preset in the center position. (5) 3 Position Switch The left position: OFF The middle position: STANDBY The right position: ON In the “STANDBY” position, the audio is muted. (6) LED Indicator Turns red when the switch is in “STANDBY” position and green in “ON” position.
Removing the 31XT: Push down on the release button and pull out. (1) Turn the bottom half of the case counter-clockwise until it is completely off. (2) Insert one fresh alkaline “AA” battery into the compartment. Make sure battery polarity is correct. Replace the bottom half of the case and turn clockwise until snug. DO NOT OVERTIGHTEN. (3) Frequency Label: The frequency label indicates what frequency (in MHz) the transmitter broadcasts on. The AZDEN receiver in use must also be on the same frequency.
(3) The frequency label indicates what frequency (in MHz) the transmitter broadcasts on. The AZDEN receiver in use must also be on the same frequency. + - (4) 3 Position Switch The bottom position: OFF The middle position: STANDBY The top position: ON In the “STANDBY” position, the audio is muted. (5) LED indicator Turns RED when the switch is in “STANDBY” position and GREEN in “ON” position. NOTE: Remove the battery if the transmitter will not be used for a long period of time.
(2) Insert one fresh Alkaline 9-volt battery into the compartment. Make sure the battery polarity is correct. (3) Frequency Label The Frequency label indicates what frequency (in MHz) the transmitter broadcasts on. The AZDEN receiver in use must also be on the same frequency. (4) 31IT 1/4-inch plug Plugs into output on electric guitars and keyboards. or (4) 31LT lavalier mic: Clips onto a tie, lapel, etc. The transmitter’s cable doubles as an antenna.
the receiver to a mic/line input on your audio mixer or amplifier. Plug the receiver’s AC adaptor into the 12V input jack on the receiver, and then plug it into the 110-120 VAC electrical outlet. With the volume of your mixer or amplifier set to minimum level, turn your system’s power on. Turn on the transmitter(s). Make sure all LEDs on the receiver and transmitter(s) are operating as described in the preceding pages.
