How to install the batteries in your M2R Stereo Receiver Each M2R Stereo Receiver uses two 1.5V AA batteries, not included. Alkaline type is recommended. Always replace all batteries. Make certain the receiver power is Off before replacing batteries. 1. Open the battery compartment door by sliding tabs in the direction of the arrows and rotating the door open.
IEM M2 Owners Manual Page 7 of 9 2. Observe correct polarity as marked and carefully insert two fresh 1.5V AA alkaline batteries 3. Close the door, making certain the latches click securely in place. Note: If the battery indicator LED turns red, replace the batteries. System Operation Placement: Location For best operation, place the transmitter near the performance location. The transmitter should be at least 3 ft. from the receiver. Keep antennas away from noise sources such as digital equipment, motors, automobiles and neon lights, as well as away from large metal objects. Audio-Technica recommends that you do not locate the M2T Stereo Transmitter in the same rack with a wireless microphone receiver. System set-up: 1. Plug in the included AC adapter and connect to transmitter’s DC input. 2. Insert two AA batteries in the receiver, observing polarity as indicated. 3. Set the receiver and transmitter to the same frequency group and frequency channel. (See page __.) Note: Do not set more than one transmitter to the same frequency. 4. Power on your receiver (without headphones) with volume in minimum position Note: At this point, check to be certain the RF indictor is not illuminated. If it is illuminated before you have powered on the transmitter, this means the frequency you have chosen is already in use. Choose another frequency. 5. Power on the transmitter. 6. Check the RF LED on your receiver to be certain it is illuminated. (This indicates that it is receiving a signal from the transmitter.) 7. Power off both units (transmitter and receiver). Audio set-up: 8. Connect audio source(s) to inputs on the rear panel of the transmitter. There are two combination audio inputs on the back panel; each offers both XLR and ¼” inputs. Use shielded audio cable for the connection between the transmitter and the audio source (mixer, microphone, or instrument). Note: If you want to send the audio signal through your transmitter (to another transmitter or recording device, for instance), use the Loop output connectors on the back of the M2T Stereo Transmitter. The R/2 XLR jack duplicates the unprocessed signal of the R/2 input; the L/1 XLR jack duplicates the unprocessed signal of the L/1 input. These are not affected by front panel settings. 9. Turn on the transmitter.
IEM M2 Owners Manual Page 8 of 9 10. Set the attenuator on rear panel of transmitter to appropriate level. If connecting a mic level source, set the attenuator to 0 dB. If connecting a line-level source, set the attenuator to -10 dB. If Input Level LEDs are consistently red or orange, set the attenuator to -20 dB or turn the trim down for corresponding audio input. 11. Trim levels are set at the factory to the maximum position; adjust if necessary. (See page __.) 12. Plug earphones into jack on receiver. Turn the locking ring clockwise until tight. NOTE: Do not put the headphones in your ears at this point. 13. Turn on receiver with volume in minimum position. 14. With volume on receiver at minimum position, put earphones into your ears and gradually increase volume until appropriate level is reached. How to select a frequency 1. Select a frequency group (A-J) via the Frequency Group Selector on the front panel of the M2T Stereo Transmitter. 2. Next, select a channel (1-10) via the Frequency Channel Selector on the front panel of the M2T Stereo Transmitter. 3. Before turning on your receiver, use the provided screwdriver to set the receiver channel selector switches (see page __) to the same frequency group and channel you have selected on the transmitter. Select frequency groups A-J and channels 1-10. The transmitter may be either on or off when changing channels (frequencies). Each transmitter/receiver system operates on a choice of 100 switch-selected frequencies per band (10 frequencies in 10 frequency groups). Available frequencies are shown in the chart below. In multi-channel systems, always use the same frequency group. Note that M2R Stereo Receiver and M2T Stereo Transmitters operate either in TV channels 38-43, identified as Band L, or in ….. M2 “L” Band transmitters must be used only with “L” Band receivers; the same holds true for all the frequency bands (i.e., always use receivers and transmitters that operate in the same band). The Band marking will be found on the antenna of both the M2T Stereo Transmitter and M2R Stereo Receiver. Note: Because these frequencies are shared with TV broadcasting (depending on country of use), frequency selection is largely dependent upon which TV broadcast channels are in operation where the wireless system is to be used.

IEM M2 Owners Manual Page 9 of 9 Squelch Control The squelch control is preset at the factory, but can be adjusted if you must use the system in a high RF interference area. If there is audio output from the receiver when your transmitter is off, adjust the squelch control so the system will receive the signal from your transmitter but “squelch” or eliminate the unwanted background RF noise. This adjustment can cause a reduction in useable range of the wireless transmitter, so set the control to the lowest position which reliably mutes the unwanted RF signals. Setting Levels Correct adjustment of transmitter audio input and receiver audio output is important for optimum system performance. M2T UHF Stereo Transmitter The M2T Stereo Transmitter trim (volume) controls (See L/1 and R/2 trim control, page ...) have factory pre-set audio input levels. Factory setting is full clockwise, maximum gain. Set the receiver's AF Level control to its full clockwise position (maximum). With a source plugged into the transmitter (at typical levels, check the AF peak indicator on the transmitter. If the AF peak indicator is red, it may be necessary to adjust the transmitter trim control clockwise until the AF peak indicator is illuminated only on audio peaks. No further transmitter trim adjustments should be needed, as long as the acoustic input does not change significantly. Aux In jack The M2R Stereo Receiver offers a ¼” Aux In jack that allows you to add another audio source, such as a click track, or ambient microphone • To use a condenser microphone as an ambient microphone, select Mic-level on the DIP switch inside receiver (see page ___), plug MT830 Omnidirectional Condenser Lavalier Microphone or equivalent into the Aux In jack, and adjust volume control as needed. • To use the Aux-in jack as a line-level input, select Line-level on the DIP switch inside the receiver (see page___), plug line-level source into the Aux In jack.
