3. GTX24 UWB Beltpack Transmitter 3.1 Batteries The GTX24 operates via 2 x AA size batteries. When inserting the batteries into the GTX24, observe correct polarity as marked. Do not peel off or damage the outer tube of the battery. Do not use a leaking battery. If battery leakage occurs, avoid contact with skin. If contact occurs, immediately was thoroughly with soap and water. If battery leakage comes into contact with your eyes, immediately flush with water and seek medical attention.
3.2 Transmitter Controls • An On/Off power switch is located in the battery compartment. • The adjustable transmitter parameters are shown on a display located on the face of the transmitter. • The adjustable transmitter parameters are: 1. System ID (SYS) – Each transmitter must be assigned a system ID (1-9) that must match the system ID set on the GTX3224 Each transmitter will only transmit after it receives permission to transmit from the system.
required. Simply turn each transmitter to a channel time slot from 01 to 24 and operate. Note: If two GTX24 transmitters are set to the same channel time slot and same system ID #, they will not operate properly. 3. Input level (GAIN) – Adjustment of the audio input level (0 dB to 20dB in 2dB Steps). The display figures will only be illuminated when the user is adjusting the transmitter. Pressing any button will activate the full display for 10 seconds.
• Adjustment Process: 1. Press and Hold (2 sec) the button associated with the parameter to be adjusted - SYST, CHAN or GAIN. 2. The selected parameter value will flash on the screen. 3. Make the desired adjustment via the up down arrow keys while the value is flashing. 4. The new value will be shown, and remains flashing until confirmed. 5. Confirm the new value by continuing to hold the parameter button from step 1 until the flashing stops. 6.
4. GTX24HH UWB Handheld Transmitter 4.1 Batteries The GTX24 operates via 2 x AA size batteries. Access the battery compartment and GTX24HH controls by gently unscrewing and sliding open the lower outside microphone handle. When inserting the batteries into the GTX24HH, observe correct polarity as marked. (Note they both orient with + “up”). Do not peel off or damage the outer tube of the battery. Do not use a leaking battery. If battery leakage occurs, avoid contact with skin.
4.4 On/Off and Transmitter Controls The On/Off power switch and Controls are inside the microphone body, opposite of the battery compartment. Access this area by gently unscrewing and sliding open the lower outside microphone handle. The adjustable transmitter parameters are shown on a display located on inside the transmitter. The adjustable transmitter parameters are: 1.
To operate more than one transmitter with the system, you must set each GTX24HH to a different channel number. No frequency coordination, registration or database checking is required. Simply turn each transmitter to a channel time slot from 01 to 24 and operate. Note: If two GTX24HH transmitters are set to the same channel time slot and same system ID #, they will not operate properly. 3. Input level (GAIN) – Adjustment of the audio input level (0 dB to 20dB in 2dB Steps).
• Adjustment Process: 7. Press and Hold (2 sec) the button associated with the parameter to be adjusted - SYST, CHAN or GAIN. 8. The selected parameter value will flash on the screen. 9. Make the desired adjustment via the up down arrow keys while the value is flashing. 10. The new value will be shown, and remains flashing until confirmed. 11. Confirm the new value by continuing to hold the parameter button from step 1 until the flashing stops. 12.
Operating somewhat like micro-cell devices, each GTX32 transceiver unit houses both transmit and receive antennas. It sends control, system and sync coordination information to all GTX transmitters within its range. Via the TDMA scheme, it also receives all 24 possible channels of audio data from 24 possible simultaneous transmitters and processes the signals for return to the GTX3224 MCU. Once at the MCU, several layers of error correction and signal quality decision are processed.
The pattern becomes very narrow when in close proximity, and side-lobes are present when operating within 16 feet of the device. There is also a small rearlobe. The signals that are transmitted and received in this system are very effectively bounced and utilized via multi-path. A general antenna pattern estimate drawing is shown below, but due to very positive influence of multipath signals, this drawing does fully represent the operation once in a physical space.
Important note: The GTX wireless microphones system uses a proprietary communication protocol over the CAT-5 cable for the purposes of extended range and highly precise system synchronization. GTX32 transceivers DO NOT connect via ethernet. DO NOT plug an ethernet connection into a GTX3224 transceiver input jack. GTX32 transceivers can be operated via a home-run connection through a physical switch if this allows for easier set-up and cabling, but they will not operate through a network or ethernet switch.
A sometimes convenient location is to mount the GTX32 transceiver directly to a camera jib. This ensures coverage following talent. GTX32 Rear View RJ45 Connector for Cat5 Cable 6. GTX3224 Main Control Unit The main control unit (sometimes referred to as the MCU) is the central connection and control point for the system. It also supplies the power required to operate up to 32 GTX32 transceivers via standard shielded CAT 5 cable.
The GTX3224 operates via 2 fully redundant 110-220V 50-60Hz AC power supplies via 2 separate standard IEC power cables. The unit is fully operational with a single power cable and power supply. A front panel display will indicate a blue light for the 1st power supply and a green light for the 2nd power supply.

7. GTX3224 Main Control Unit GUI Interface The GUI interface is divided into four screens: Home Screen – This screen will display an overview of all 24 transmit channel slots at once. The user will be able to select the “active” channel on this screen by tapping the corresponding channel tile. The audio from the active channel will be sent to the headphone monitor output.
a. Home Screen The home screen displays all 24 possible channel time slots. If a transmitter is turned on and linked for a given channel time slot, a green BER bar will be displayed corresponding to this channel. A black (or red for warning level) bar will be displayed on the right side of the green BER bar to indicate battery level. Three circles above the green BER bar indicate the link condition of at least the desired three simultaneous (diversity) reception from GTX32 transceivers.
b. Transmitter Detail Screen The detail screen gives the user a view of the selected channel’s transmitter information in one place; including a history of the transmitter’s link status, and battery use details. A history of link information is displayed over a user-selectable time scale from two to sixty minutes (additional time – up to 31 days of time-stamped logging is available via the separate companion computer logging software).
A battery life gauge is available on the transmitter detail screen. The gauge shows actual minutes left for operation. c. Matrix Screen - GTX32 transceiver Measurement The matrix screen allows the user to visualize specific connections between 32 possible transceivers and 24 possible transmitters. There are two modes: Receiver Link and Transmitter Link.
The Σ button is used to view all GTX32 transceivers that are connected to ANY active transmitter rather than just a single transmitter. This mode is used to test which transceivers receivers are most effective in a given set up, and may assist in placement. When the user selects the matrix screen, the system will first check for added GTX32 transceivers; without interrupting the operation of the active receivers or the audio output.
Σ-mode operation is similar - when selected, the system will show transmitters that are connected to any GTX32 transceiver in the system. This is a quick way to make sure that all transmitters are connected to the system by at least one receiver. e. Setup Screen – User “TOOLS” The setup screen allows the user to monitor certain key system performance values or settings, and allows system parameters and operation values which may be determined by user preferences. Monitor and control includes: 7.
To enter and activate any of the TOOLS screen functions, press on the screen graphic for the desired parameter. The display for the selected parameter will blink. Press the “SET” button on the number pad to confirm the change. To enter TEST MODE, press on the screen graphic at the “OFF” position under test mode. The parameter will begin to blink. Enter the #s 3224 on the keypad and then press “SET.” The display for TEST MODE will now change to a green color and display “ACTIVE.
