System Overview

The new groundbreaking GLX­D Wireless Systems from Shure combine the leading edge of Automatic Frequency Manage­ ment technology with best-in-class intelligent lithium ion battery rechargeability, world-renowned microphones and unparalleled design and construction. The compact low­profile design easily fits into pedalboard configurations. Built­in chromatic tuner sim­ plifies setups while offering flexible tuning options. Advanced frequency hopping technology detects interference and automati­ cally switches to a clear backup channel to prevent audio dropouts. Channel scanning finds the best receiver channel for wire­ less audio and automatically links to the transmitter.

•Exceptional digital audio clarity

•Built-in tuner with customizable functionality and display options

•Operates in 2.4 GHz spectrum, available worldwide.

•Compact rugged metal construction

•Receiver compatible with standard 9 V DC positive tip or negative tip power supplies (250 mA minimum)

•Rechargeable transmitter batteries deliver cost-efficiency and up to 11.5 hours of runtime

•Adjustable transmitter gain to optimize audio signal

•Automatically detects and avoids interference to preserve audio quality

•Globally-unlicensed 2.4 GHz frequency band allows operation of up to 4 compatible systems in a typical setting and up to 8 compatible systems under ideal conditions

•RF back-channel for remote control of transmitter functions

•Automatic transmitter power-off to conserve battery life when transmitter is not in use.

Quick Start

To reduce set up time, the transmitter and receiver automatically link to form an audio channel the first time they are powered on and never have to be linked again.

Note: If using multiple effects pedals, place the receiver pedal first in the signal chain.

Step

Step

Step

Connect power supply to the receiver and plug the power cord into an AC power source.

Connect the transmitter to the instrument and turn on the transmitter.

Connect receiver audio output to an amplifier or mixer. Turn on the receiver: The blue rf LED will flash while the transmitter and receiver form a link. When the link has successfully formed, the rf LED will remain illuminated.

Note: The transmitter and receiver will remain linked for future usage. At power-up, the blue rf LED will illuminate,

skipping the linking step.

Step	Check the audio and adjust the gain if necessary.

For best results, the belt should be pressed against the base of the clip.

Batteries and Charging

GLX-D transmitters are powered by Shure SB902A lithium-ion rechargeable batteries. Advanced battery chemistry maximizes runtimes with zero memory effects, eliminating the need to discharge batteries prior to charging.

When not in use, recommended battery storage temperature is 10°C (50°F) to 25°C (77°F).

Note: The transmitter will not pass RF or audio signals when connected to the charging cable.

10/34

Shure Incorporated

The following battery charging options are available:

Charging from an AC Power Source

1.Plug the charging cable into the charging port on the transmitter.

2.Plug the charging cable into an AC power source.

Charging from a USB Port

1.Plug the USB charging cable into the charging port on the transmitter.

2.Plug the cable into a standard USB port.

LED Status During Charging

The following LED states indicate battery status when the transmitter is connected to a charger:

•Green = charging complete

•Green Flashing = battery charge > 90%

•Red = battery charging

•Amber Flashing = battery error, replace battery

Charging Times and Transmitter Runtimes

Use the following table to determine approximate battery runtime based on the duration of charging time. Times shown are in hours and minutes.

Note: Batteries charge faster when using an AC powered charger versus a USB connection.
