DD4GLXD1Z3Wireless Bodypack Transmitter

Shure Incorporated 3/20 • • • • • • • • GLXD4+ and GLXD4R+ System Overview The GLX-D+ wireless systems from Shure combines the leading edge of automatic frequency management technology with best­in­class intelligent lithium­ion battery rechargeability, world­renowned microphones and unparalleled design and construc­ tion. Available in a wide offering of bodypack and handheld configurations - including vocal, headset and presenter systems as well as traditional guitar options. The GLX-D+ wireless systems define the newest standard for seamless ease of operation and exceptional digital audio clarity. Exceptional digital audio clarity Operates in 2.4 GHz and 5.8 GHz spectrum, available worldwide Rechargeable batteries deliver cost-efficiency and up to 17 hours of runtime at 2.4 GHz and 12 hours of runtime at 5.8 GHz. Adjustable transmitter gain to optimize audio signal Automatically moves away from interference without audio interruption RF back-channel for remote control of transmitter functions Globally­unlicensed 2.4 GHz and 5.8 GHz frequency band allows operation of up to 4 compatible systems in a typical set­ ting and up to 8 compatible systems under ideal conditions 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: When setting up multiple receiver systems, turn on and link each transmitter/receiver pair one at a time to prevent cross-linking. Step ① Connect power supply to the receiver and plug cord into an AC power source. Connect the audio output to an amplifier or mixer. Step ②Install charged transmitter batteries. Step ③ Turn on the transmitter and receiver. The blue RF LED will flash while the transmitter and re­ ceiver form a link. When the link has successfully formed, the RF LED will remain illuminat­ ed. 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 ④Check the audio and adjust the gain if necessary. DRAFT Shure Incorporated 4/20 ◦ ◦ ◦ Receiver Controls and Connectors ①Antenna Two antennas per receiver.

Place the battery into the transmitter. Close the battery door and slide the latch to lock. Handheld Transmitter Unscrew and remove the battery cover. Place the battery into the transmitter. Replace and tighten the battery cover. Multiple Receiver Systems For ease of set up, frequencies are divided into groups to best match the channel requirements for your system. Select the group by determining the total number of receivers in your system (channel count). All receivers in the system must be set to the same group. DRAFT Shure Incorporated 9/20 1. 2. 3. 1. 2. 3. Group Channel Count (Number of Re­ ceivers) Number of Backup Frequencies Notes 1Up to 43Initial factory setting. 2Up to 5*3 Best multi-channel group if you experience interfer­ ence. 3Up to 8*0 For large multi-channel systems. Only use Group 3 in controlled Wi-Fi environments because there are no backup frequencies to avoid interference…

Duty Cycle Factor Measurement 2.1. Test Requirement Unless otherwise specified, when the radiated emission limits are expressed in terms of the average value of the emission, and pulsed operation is employed, the measurement field strength shall be determined by averaging over one complete pulse train, including blanking intervals, as long as the pulse train does not exceed 0.1 s (100 ms). In cases where the pulse train exceeds 0.1 s, the measured field strength shall be determined during a 0.1 s interval. The exact method of calculating the average field strength shall be submitted with any application for certification or shall be retrained in the measurement data file for equipment subject to notification or verification. 2.2. Test Procedures a. The EUT was set to communicate with GLXD4+ continuously. b. A horn antenna was positioned at a 3 meter distance from the EUT. The output of the antenna was connected to the input of a spectrum analyzer. c. The center frequency of the spectrum analyzer was set to the transmit frequency of the EUT. d. The frequency span of the spectrum analyzer was set to 0Hz so that the time domain trace of the transmitted pulse of the EUT was displayed on the spectrum analyzer. e. The sweep time of the spectrum analyzer was adjusted so that the beginning and end of a single pulse could be seen on the display of the spectrum analyzer. f. The single sweep function of the spectrum analyzer was used multiple times to determine the maximum pulse width of the EUT. g. The maximum pulse width display of the spectrum analyzer was recorded and then plotted using a 'screen dump' utility. h. The sweep time of the spectrum analyzer was then adjusted to 100msec. Report No.: 2103RSU004-U3 5 of 11 i. The single sweep function of the spectrum analyzer was used multiple times to determine the maximum number of transmitted pulses that occurred in a 100msec time period. j. The maximum number of pulses transmitted in a 100msec time period was recorded and then plotted using a ‘screen dump’ utility. k. The duty cycle correction was calculated using the following equation: Duty Cycle Correction Factor (dB) = D.C. (dB) D.C. (dB) = 20 x log (((pulse width (msec))x(#pulses in a 100msecperiod)/100msec) Report No.: 2103RSU004-U3 6 of 11 2.3.
