Multiple System Setup
When setting up multiple systems, designate a single bodypack to scan for available frequencies and download them to all the
rack units.
The bodypack must be from the same frequency band as all the transmitters.
Power on all the rack units. Turn off the RF. (This prevents them from interfering with the frequency scan.)
Note: Turn on all other wireless or digital devices as they would be during the performance or presentation (so the scan will detect and avoid any in
terferance they generate).
Use the bodypack to scan for a group by pressing and holding the scan button for two seconds.Thebodypackdis
plays the group and the number of available channels, and flashes SYNC NOW....
Important: Note the number of available channels. If you have more rack units than available channels, eliminate potential sources of interference
and try again, or call Shure Applications for assistance.
Sync the bodypack with the first rack unit by aligning the IR windows and pressing sync.
Press scan again on the bodypack to find the next available frequency.
Sync the bodypack with the next rack unit.
Repeat with all the rack units.
Sync each performer's bodypack to its respective rack unit by aligning the IR windows and pressing snyc. DO NOT
press scan on the bodypacks.
Turn on the RF on all rack units. The systems are ready to use.
CueMode
CueMode allows you to upload the name and frequency settings from multiple rack units and store them as a list on a single
bodypack. You can then, at any time, scroll through that list to hear the audio mix from each transmitter, just as each performer
does during a show.
CueMode lists are retained even if CueMode is exited, the bodypack is turned off, or batteries are removed.
Note: Set the channel frequency and assign display names for each transmitter before creating your CueMode list.
Adding Transmitters to the CueMode List
Note: The transmitter must be from the same frequency band as the bodypack.
Open the battery door and press the enter button.

MixMode for Multiple Systems
Configure each system for MixMode. From the mixing console, send a mix of the whole band to input 2 of the first transmitter.
Connect the LOOP OUT R output to the R/CH2 input of the next transmitter. Continue the chain with all the transmitters.
Next, create solo mixes for each performer. Send each mix to input 1 of the transmitter for that performer.
Floor Monitors
Send the audio from the LOOP outputs to onstage loudspeakers. The bodypack and the onstage monitors receive the same
audio signals.
Note: The LOOP audio outputs will not drive passive loudpeakers, and must be sent to a power amplifier or an active loudspeaker.
Recording Devices
To record a performance, connect the LOOP outputs to the inputs of a recording device.
Squelch
Squelch mutes audio output from the bodypack when the RF signal become noisy. While squelch is activated, the blue LED on
the bodypack turns off.
For most installations, squelch does not need adjustment, and it keeps the performer from hearing hiss or noise bursts if the
RF signal becomes compromised. However, in congested RF environments or in close proximity to sources of RF interference
(such as large LED video panels), the squelch may need to be lowered to prevent excessive audio dropouts. With lower
squelch settings, the performer may hear more noise or hiss, but will experience fewer audio dropouts.
Important: Before lowering squelch, first try to eliminate the problem by finding the best set of frequencies for your installation and removing potential sources
of interference.
Caution: Turning off or lowering the squelch setting can increase the noise level and cause discomfort to the performer:
Do not lower the squelch setting unless absolutely necessary.
Turn earphone volume to the lowest setting before adjusting squelch.
Do not change the squelch setting during a performance.
Turn up the transmitter level setting to make noise or hiss less noticeable.
Squelch Settings
HIGH (NORMAL) Default factory setting.
MID Moderately decreases the signal-to-noise ratio required to squelch the receiver.
LOW Greatly decreases the noise squelch threshold.
PILOT ONLY* Turns off noise squelch leaving only pilot squelch on.
NO SQUELCH* Turns off noise and pilot tone squelch. (Sometimes used as a debugging tool by
monitor engineers or RF coordinators to "listen" to the RF environment.)
