System Overview The new groundbreaking GLX-D Wireless Systems from Shure combine the leading edge of Automatic Frequency Management technology with bestin-class intelligent lithium ion battery rechargeability, world-renowned microphones and unparalleled design and construction. The compact low-profile design easily fits into pedalboard configurations. Built-in chromatic tuner simplifies setups while offering flexible tuning options.
Guitar Pedal Receiver Overview ① Power Switch Turns power on or off. ② DC Power Connector Connect DC power supply (9 to 15 V DC, 250 mA min., 400 mA max.) Note: Compatible with positive tip or negative tip power supplies. 1 4 ③ Audio Output Jack Connect to amplifier or mixer. 2 3 link 5 Note: If using multiple effects pedals, place the receiver pedal first in the signal chain. ④ USB Port For uploading firmware updates group 6 6 mode audio mute rf channel ⑥ Antenna Two antennas per receiver.
Bodypack Transmitter ① Antenna Carries wireless signal. ② Status LED Indicates transmitter status. 4 3 2 1 off on ③ Power Switch Turns the transmitter on/off. ④ TA4M Input Jack Connects to a 4-Pin mini connector (TA4F) microphone or instrument cable. ⑤ Micro USB Charging Port Connection for battery charging.
Batteries and Charging GLX-D transmitters are powered by Shure SB902 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.
Multiple Receiver Systems For ease of set up, available frequencies are divided into three groups based on the number of receivers supported. All receivers in the system must be set to the same group. To select a group, determine the total number of receivers in the system (channel count), and then select the appropriate group. Note: To maximize the number of receivers on-air, Group 3 does not offer backup frequencies.
2.4 GHz Spectrum Overview GLX-D operates within the 2.4GHz ISM band which is utilized by Wi-Fi, Bluetooth, and other wireless devices. The benefit of 2.4GHz is that it’s a global band that can be used anywhere in the world, license free. Overcoming the Challenges of 2.4GHz Coexisting with Wi-Fi The challenge of 2.4GHz is that Wi-Fi traffic can be unpredictable.
Receiver Operation Audio Gain Adjustment Transmitter gain has an adjustment range from -20 dB to +40 dB, in 1 dB increments. link group link channel mode group Tip: Try the 0 dB (unity gain) setting as a starting point, and then make gain adjustments if necessary. 1. Press and hold the mode button on the receiver until dB appears on the display. mode audio mute rf audio mute rf channel 2. Press the up/down arrows to adjust the gain. For faster adjustments, press and hold the buttons.
Tuner Menu Enter tuner mode by pressing the footswitch. In tuner mode, the controls will only affect tuner functions, RF and audio settings are not affected. Note: The audio signal does not pass through the tuner, eliminating the need for bypass switches commonly found on wired tuners.
Using the Tuner 1. Press the footswitch to enter tuner mode. 2. Play each note individually. The display shows the name of the note. 3. Adjust tuning until both indicators illuminate and the needle or strobe indicate that tuning is correct. Needle Mode Both tuning indicators and the center green segment will illuminate when the note is in tune. Strobe Mode Both tuning indicators will illuminate and the strobe segments will remain stationary when the note is in tune.
Troubleshooting Issue Indicator Status Solution No sound or faint sound Receiver RF LED on • Verify all sound system connections or adjust gain as needed (see Adjusting Gain) • Verify that the receiver is connected to mixer/amplifier Receiver RF LED off • Turn on transmitter • Make sure the batteries are installed correctly • Link transmitter and receiver (see Linking topic) • Charge or change transmitter battery Receiver display off • Make sure AC adapter is securely plugged into electrical outlet
