  • Page 10 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.

  • Page 11: Transmitter Controls

    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.
  • Page 12 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).
  • Page 13 • 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.
  • Page 14 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.
  • Page 15 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.
  • Page 16 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.
  • Page 17 • 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.
  • Page 18 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.
  • Page 19 Note: Although a single GTX32 transceiver may pick up all 24 channels of operation, Alteros recommends that the system be set up with a coverage area that will provide for at least three GTX32 transceivers in link with each GTX24 transmitter at all times from any location/orientation.
  • Page 20 For more information about switching, we suggest you look into the Alteros SWX8 and SWX8C switches.
  • Page 21 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.

  • Page 22: Front Panel

    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 1 power supply and a green light for the 2 power supply.

  • Page 24 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.

  • Page 25: Home Screen

    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.
  • Page 26 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 –...
  • Page 27 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.
  • Page 28 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.
  • Page 29 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.
  • Page 30 “SET.” The display for TEST MODE will now change to a green color and display “ACTIVE.” To immediately stop the TEST TONE, press on the screen where it says “OFF.” For further information regarding the set-up or operation of the Alteros GTX UWB Wireless Microphone System, please see our website: www.Alteros.tech...
