Introduction
Please enjoy the easy and exciting performance that the GXL™
Wireless Series provides for your next performance. CAD Audio
has been creating valued product since 1938 and prides itself on
developing and supporting the live performer. Our design criterion
was straightforward. Develop a high value wireless microphone
system that can cope with today’s challenging RF environment that
is both easy to use and exciting to operate.
The GXLU Wireless includes the following features:
• Two discrete channels of wireless packaged in
one receiver chassis.
• Each channel has RF and AF indicator lights that indicate
the presence of connectivity and audio source.
• UHF Frequency Operation for increased operating range
• Advanced dipole antenna technology for increased
operating range.
• Three output options on the receiver for maximum
performance and exibility of use.
- Professional balanced XLRM-type discrete output
- Professional balanced XLRM-type mixed output
- Professional ¼ inch output for easy output to a guitar amp
or mixer equipped with ¼ inch input connections.
• Handheld transmitter outtted with on/off and mute function
for exibility of use.
• Bodypack transmitter outtted with on/off, mute function
for exibility of use.
• Handheld transmitter features battery life indicator.
• Battery life of >10hrs.
• All Bodypack systems ship with WXGTR guitar cable and
WXHW condenser headworn mic included.

• Insert new high quality alkaline batteries into your transmitter.
• Utilize the exible output format of the receiver to match your
application. Connect to mixer or amplier appropriately.
• Power up the receiver.
• Power up the transmitters.
• The RF indicator light will show connectivity between the
receiver and the transmitter. The AF indicator light shows
the presence of an audio source.

Individuals with cardiac pacemakers and other similar medical devices
should consult with their physician before using any RF devices. Though
the output level of this wireless system is below 50 milliwatts, the
proximity of the transmitter to the implant device could pose a threat.
As with any wireless product, environmental conditions can reduce or in
some cases prohibit a successful connection between the transmitter
and the receiver.
Most users of CAD Audio wireless products in the United States do not
need a license for operation. However, the rules for unlicensed operation
state that this device must not operate in excess of 50 milliwatts and it
must not cause harmful interference to other wireless devices. Wireless
products meeting CAD factory standards adhere to these rules. The FCC
reserves the right to change these rules at any time.
