Wireless Boundary Microphone The Shure MX690 microphone offers cable-free installation for corporate boardrooms or other applications requiring exible congurations. The MX690 operates within the 518–865 MHz bands and is compatible with Shure SLX wireless systems.
2 Features Sleek, low prole design • Frequency agile, microprocessor controlled transmitter • IR link to SLX receiver for automatic frequency • synchronization Programmable frequency Group/Ch.
3 Microphone Placement Place 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.
4 The low-cut lter attenuates frequencies below 150 Hz by 6 dB per octave. Low-Cut Filter Filter disabled (as supplied) Low-cut lter.
5 Battery Installation Open the battery compartment 1. as shown. Insert two1.5V “AA” batteries. 2. 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.
6 Press and hold the 1. ON/OFF PROGRAM button for approximately 2 seconds. The LCD illuminates. T o turn the transmitter off, press and hold the 2. ON/OFF PROGRAM button again. Note: Use the button on the bottom of the transmitter to power it on without opening the battery compartment.
7 Mute Button The mute button can be congured for toggle or momentary operation. T oggle (as supplied) The PUSH button toggles the microphone between active and muted states.
8 Mute Indicator The 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.
9 Locking Settings Press 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 .
10 Power off all transmitters. 1. Power on all receivers. 2. Begin with the rst transmitter . Open the battery cover and 3. power it on. Aim the IR sensor at the rst receiver IR port. The transmitter 4. should be no more than 15 cm (6 in.) from the receiver .
11 Troubleshooting If you encounter difculty 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.
12 Frequency Selection Shure offers wireless systems in a selection of bands that conform to the different government regulations of specic nations or geographic regions.
13 Frequency Bands Band Range Output H5 518–542 MHz 10 mW J3 572–596 MHz 28 mW L4 638–662 MHz 10 mW P4 702–726 MHz 10 mW R13 794–806 MHz 10 mW R5 800–820 MHz 10 mW S6 838–865 MHz 10 mW J.
14 The 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 .
15 Transmitter Specications Operating Range 30 m (100 ft.) Note: Actual range depends on RF signal absorption, reection, and interference Frequency Stability ±10 ppm Maximum Frequency Deviation.
16 Microphone Specications T ype Condenser (electret bias) Frequency Response 50–17000 Hz Polar Pattern ( at 1 kHz) Cardioid Sensitivity ( at 1 kHz , open circuit voltage) –33 dBV/Pa (22 mV) 1 .
