Zaxcom TRXLA3 Transmit Menu Transmitter Disable - Record only mode TX DISABLE : NORMAL TX MODE Record Only Mode - Will set the TRXLA3 to act as a standalone recorder and will not transmit any audio over UHF. This will conserve battery power since the transmitter is disabled. • Normal TX Mode - Will allow the TRXLA3 to both transmit audio and record on its internal SD card.
Zaxcom TRXLA3 Record Menu RECORD MENU SD Card Format This menu will only appear if a card was inserted prior to booting up PRESS UP KEY 5X: TO ERASE CARD The Micro SD card is erased and formatted from this menu. Please note that all cards need to be formatted in a 3 series transmitter prior to recording. Before formatting the card, the transmitter can optionally be renamed (see set up menu). When a transmitter is named that name is included in the recorded file names.
Zaxcom TRXLA3 Record Menu Time Left on Card This menu will only appear if a card was inserted prior to booting up TIME LEFT 20 H TIME USED 4 H This page displays the remaining record time left on the card as well as the time already recorded on the card. Automatic Record after Boot up RECORD ON BOOTUP OFF Record on boot up allows the onboard recorder to automatically start recording after the transmitter boots up. • ON - The onboard recorder will automatically start to record after the TRXLA3 boots up.
Zaxcom TRXLA3 ZaxNet Menu ZAXNET MENU ZaxNet Mode ZAXNET MODE: TX This menu sets the mode of the ZaxNet transceiver. • OFF - The ZaxNet transceiver is disabled. The TRXLA3 will not receive ZaxNet commands or time code and it will not send any ZaxNet audio. Please note if ZaxNet mode is set to OFF only the group and unit code menu will be accessible. • RX - The ZaxNet transceiver will receive ZaxNet commands and time code. This screen will display what ZaxNet data is being received by the TRXLA3.
Zaxcom TRXLA3 ZaxNet Menu Group Code Set REMOTE CONTROL GROUP CODE = 1 This menu is where the TRXLA3 is assigned to a group. The group code allows transmitters to be grouped together so they can be controlled via ZaxNet without affecting others. So for example a TRXLA3 set to Group 1 will be controlled by a ZaxNet transmitter set to Group 1 and a TRXLA3 assigned to group 2 will be controlled by a Group 2 ZaxNet transmitter. This is helpful if two or more people on set are sending ZaxNet commands.
Zaxcom TRXLA3 ZaxNet Menu ZaxNet Receive Before Transmit Time RX TO TX TIME: OFF (NORMAL RX) ZAXNET RX TO TX: 0 SEC: TX ONLY ZAXNET RX TO TX: 20 SEC Receive only mode. The ZaxNet transceiver will only receive ZaxNet and NOT go into transmit mode. Therefore no ZaxNet TC and/or audio will be transmitted. This setting shuts off the ZaxNet transmitter. Transmit only mode. The ZaxNet transceiver will only transmit ZaxNet TC and audio and will NOT receive wireless TC or ZaxNet commands.
Zaxcom TRXLA3 ZaxNet Menu IFB Receive Pulse Set This menu will only appear if the TRXLA3 is set to go into transmit in the RX to TX Time menu ZAXNET RX PULSE: OFF The ZaxNet transceiver will stay in transmit mode and never go into receive mode. IFB RX PULSE 600 SECS In this example the ZaxNet transceiver will go out of transmit mode every 10 minutes. This setting would be used so the TRX could update its time code while monitoring audio via an ERX receiver.
Zaxcom TRXLA3 Audio Menu AUDIO MENU High Pass Filter HIGH PASS FILTER: 90Hz The high pass filter is turned on and adjusted from this menu. The high pass filter range is 70Hz to 220Hz in 10Hz increments. 2K Notch Filter 2K NOTCH FILTER ON The 2K notch filter is useful in removing digital RF interference that can be introduced into some microphones.
Zaxcom TRXLA3 Audio Menu Dynamics DYNAMICS The dynamics is a soft knee compressor that is located after the analog to digital converter which will limit the dynamic range to prevent clipping during occurrences of loud audio. Dynamics is comprised of both a compressor and an expander, which operate jointly. The compressor in the dynamics can set to mild or extreme compression and features a soft knee for more transparent operation.
Zaxcom TRXLA3 Setup Menu SETUP MENU Test Tone • TEST TONE: ON • • I I I • The TRXLA3 has an internal tone generator which will generate tone so the signal chain can be properly gain staged. From this menu pressing the INC key will turn on the tone generator and cycle through the tone options which are 500Hz at -20dBFS, 1000Hz at -20dBFS or 500Hz at full scale.
