Wireless Boundary MicrophoneThe Shure MX690 microphone offers cable-free installation for corporate boardrooms or other applications requiring exible congurations. The MX690 operates within the 518–865 MHz bands and is compatible with Shure SLX wireless systems.©2007, Shure Incorporated27EN3240 (Rev. 1)Model MX690Printed in U.S.A.DRAFT
2FeaturesSleek, low prole designFrequency agile, microprocessor controlled transmitterIR link to SLX receiver for automatic frequency synchronizationProgrammable frequency Group/Channel displayProgrammable mute functionOperates on two AA batteriesCompatible with all Shure SLX Wireless systemsCommshield™ technology for protection from RF interference••••••••DRAFT
3Microphone PlacementPlace the MX690 within 1.5 m (5 ft.) of a talker. Aim the microphone toward the talkers and away from loudspeakers and noise sources. Use one microphone for every two talkers. Pickup angle with a cardioid cartridge is 130° at –3 dB.Note: To minimize RF interference, maintain a distance of at least 0.3 m (1 ft.) between transmitters. In case of interference, increase the distance between transmitters or change channels.ReceiverMake sure the receiver is within sight of the transmitter. Do not place receiver behind a metal barrier or any reective surface.Refer to the SLX Wireless System User Guide for more information, or visit www.shure.com.130º30m (100ft)DRAFT

5BatteryInstallationOpen the battery compartment as shown.Insert two1.5V “AA” batteries. Make sure the +/– terminals are properly oriented.Note: Alkaline batteries last up to 8 hours. Rechargeable, carbon-zinc and zinc-chloride batteries provide less operating time.1.2.Power MeterThe battery meter on the LCD shows remaining battery life.Low Power IndicatorSteady Red: Power low. Replace batteries immediatelyPulsing Red: Batteries dead. Transmitter cannot be turned on until batteries are replaced.DRAFT
6Press and hold the ON/OFF PROGRAM button for approximately 2 seconds. The LCD illuminates.To turn the transmitter off, press and hold the ON/OFF PROGRAM button again.Note: Use the button on the bottom of the transmitter to power it on without opening the battery compartment.1.2.Power On/OffDRAFT
7Mute ButtonThe mute button can be congured for toggle or momentary operation.Toggle (as supplied)The PUSH button toggles the microphone between active and muted states.NOTE: The microphone always powers up in the active state.MomentaryThere are two types of momentary operation:Push-to-Mute: The microphone is muted only while the button is pressed and held. Push-to-Talk: The microphone is active only while the button is pressed and held.To change between toggle and momentary: Hold the PUSH button and press the SELECT button. (Test the microphone to conrm the change.) To change between push-to-talk and push-to-mute: Set the button for momentary operation.Hold the SELECT button and press the PUSH button.1.2.HoldHoldDRAFT
8Mute IndicatorThe bi-color LED on the top of the microphone indicates whether the microphone is active or muted.The LED can also be set to ash when muted.To toggle between off and ashing, press PUSH and ON/OFF PROGRAM simultaneously.Display Mode Status IndicatorSteady (as supplied)Active = GreenMuted = RedFlashing Active = GreenMuted = Flashing Green+DRAFT
9Locking SettingsPress ON/OFF PROGRAM and SELECT simultaneously to lock or unlock transmitter settings. When locked, the current settings cannot be manually changed.Note: Locking the transmitter settings does not disable IR frequency synchronization or the High Pass/Low Cut lter.To use with a logic enabled receiver, you must perform an automatic sync. The LCD ashes “log” during sync. Once in logic mode, the LCD ashes “log” when powered up.LOGIC MODEDRAFT
10Power off all transmitters.Power on all receivers.Begin with the rst transmitter. Open the battery cover and power it on.Aim the IR sensor at the rst receiver IR port. The transmitter should be no more than 15 cm (6 in.) from the receiver. Press and hold the receiver SYNC button to send group and channel data to the transmitter. The red LED on the transmitter will stop ashing when programming is complete.Power off the rst transmitter and repeat the synchronization with each additional transmitter and receiver pair.1.2.3.4.5.Press and hold the transmitter SELECT button until the desired group number appears. Press SELECT again and release it when the desired channel number appears.1.2.Automatic Frequency SynchronizationManual Frequency SynchronizationDRAFT
11TroubleshootingIf you encounter difculty with the SLX Wireless System:Make sure both the transmitter and the receiver are turned on.Replace the battery if the battery LED is red.Make sure the Group/Channel settings for each transmitter-receiver pair are identical.Make sure there is an unobstructed line of sight between the transmitter and receiver.If necessary, reposition the receiver or decrease the distance between transmitter and receiver.Remove local sources of RF interference, such as computers or lighting equipment.Remove metal objects within 0.3 m (1 ft.) of the transmitterNote: Refer to the SLX Wireless System User Guide for complete troubleshooting procedures.•••••••Tips for Optimum PerformanceMaintain a direct line of sight between the transmitter and receiver antennas.Avoid placing the transmitter on metal surfaces.Avoid placing laptop computers or other obstructions in front of the microphone during use.Only use with a Shure SLX4 wireless receiver.••••DRAFT
12Frequency SelectionShure offers wireless systems in a selection of bands that conform to the different government regulations of specic nations or geographic regions. These regulations help limit radio frequency (RF) interference among different wireless devices and prevent interference with local public communications channels, such as television and emergency broadcasts.The system’s band and frequency range are identied on the receiver and transmitter. For example, “H4 518-578 MHz.” For information on bands available in your area, consult your local dealer or phone Shure. More information is also available at Shure’s website (www.shure.com).Licensing of Shure wireless microphone equipment is the user’s responsibility, and licensability depends on the user’s classication and application, and on the selected frequency. Shure strongly urges the user to contact the appropriate telecommunications authority concerning proper licensing, and before choosing and ordering frequencies.Changes or modications not expressly approved by Shure Incorporated could void your authority to operate this equipment.LicensingDRAFT

Please contact your national authority to obtain information on authorized frequencies for wireless microphone products in your region.DRAFT
14The Master List is an index of all frequencies in a band, including those not assigned to a Group or Channel. The Master List can only be accessed through the receiver, so the transmitter must be synchronized via the IR port. When a Master List frequency is in use, “MASTER LIST” appears on the display. Refer to the SLX Wireless System User Guide for more information.Note: Wireless devices such as cellular phones and two-way radios may interfere with wireless microphones. Keep these and other potential sources of interference away from the transmitters and receivers.Master List FrequenciesDRAFT
