DRAFT
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.
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.
130º
Receiver
Make sure the receiver is within sight of the transmitter. Do not
place receiver behind a metal barrier or any reflective surface.
Refer to the SLX Wireless System User Guide for more
information, or visit www.shure.com.

Battery
Installation
1. Open the battery compartment
as shown.
2. Insert two1.5V “AA” batteries.
Make sure the +/– terminals
are properly oriented.
Note: Alkaline batteries last up to
8 hours. Rechargeable, carbonzinc and zinc-chloride batteries
provide less operating time.
Power Meter
The battery meter on the
LCD shows remaining
battery life.
Low Power Indicator
Steady Red: Power
low. Replace batteries
immediately
Pulsing Red: Batteries
dead. Transmitter cannot be
turned on until batteries are
replaced.
DRAFT
Power On/Off
1. Press and hold the ON/OFF PROGRAM button for
approximately 2 seconds. The LCD illuminates.
2. 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.
DRAFT
Mute Button
The mute button can be configured 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.
Momentary
There 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
Hold
press the SELECT button.
(Test the microphone to
confirm the change.)
To change between push-to-talk and push-to-mute:
1. Set the button for
momentary operation.
Hold
2. Hold the SELECT button
and press the PUSH button.
DRAFT
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 flash when muted.

To toggle between off and flashing, press PUSH and ON/OFF
PROGRAM simultaneously.
DRAFT
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 filter.
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.
DRAFT
Automatic Frequency Synchronization
1. Power off all transmitters.
2. Power on all receivers.
3. Begin with the first transmitter. Open the battery cover and
power it on.
4. Aim the IR sensor at the first 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
flashing when programming is complete.
5. Power off the first transmitter and repeat the synchronization
with each additional transmitter and receiver pair.
Manual Frequency Synchronization
1. Press and hold the transmitter SELECT button until the desired
group number appears.
2. Press SELECT again and release it when the desired channel
number appears.

Tips for Optimum Performance
•
Maintain a direct line of sight between the transmitter and
receiver antennas.
•
•
Avoid placing the transmitter on metal surfaces.
•
Only use with a Shure SLX4 wireless receiver.
Avoid placing laptop computers or other obstructions in front
of the microphone during use.
Troubleshooting
If you encounter difficulty with the SLX Wireless System:
•
•
•
Make sure both the transmitter and the receiver are turned on.
•
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
Replace the battery if the battery LED is red.
Make sure the Group/Channel settings for each transmitterreceiver pair are identical.
Note: Refer to the SLX Wireless System User Guide for
complete troubleshooting procedures.

DRAFT
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 or phone Shure. More information is also available at
Shure’s website (www.shure.com).
Licensing
Licensing of Shure wireless microphone equipment is the
user’s responsibility, and licensability depends on the user’s
classification 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 modifications not expressly approved by Shure
Incorporated could void your authority to operate this equipment.

Master List Frequencies
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. 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.
