Placement  
MX890 Microphone Placement  
Place the MX890 no more than 25 cm (1 ft.) from the edge of the table.  
Aim the microphone toward the talker and away from loudspeakers and  
noise sources. Use one microphone for each talker. Pickup angle with a  
cardioid cartridge is 130° at –3 dB. Pickup angle with a supercardioid car-  
tridge is 115° at –3 dB.  
Low-Cut Filter  
The low-cut filter attenuates frequencies below 150 Hz by 6 dB per  
octave.  
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.  
MX690 Microphone Placement  
Filter disabled (as supplied)  
Place the MX690 within 1.5 m (5 ft.) of a talker. Aim the microphone to-  
ward 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.  
Low-cut filter  
Note: To minimize RF interference, maintain a distance of at least  
0.3 m (1 ft.)

Troubleshooting  
If you encounter difficulty with the SLX Wireless System  
tings. When locked, the current settings cannot be manually changed.  
• Make sure both the transmitter and the receiver are turned on.  
• Replace the battery if the battery LED is red.  
Note: Locking the transmitter settings does not disable IR frequency  
synchronization or the High Pass/Low Cut filter.  
• 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 transmitter  
Note: Refer to the SLX Wireless System User Guide for complete  
troubleshooting procedures.  
Logic Mode  
To use with a logic enabled receiver, you must perform an automatic sync.  
The LCD flashes "log" during sync. Once in logic mode, the LCD flashes  
"log" when powered up.  
Frequency Selection  
Shure offers wireless systems in a selection of bands that conform to  
the different government regulations of specific 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 identified on the receiver  
and transmitter. For example, "H4 518-578 MHz."  
For information on bands available in your area, consult your local dealer
