Media 

 

While any size card will work in the TRXLA3 transmitter we recommend using a 4GB Micro SD card. We also 
recommend only buying a brand name card such as Transcend, SanDisk.  

Please note Transcend Premium cards with the red stripe are not recommended. 

And very importantly please buy all cards from a reputable dealer because counterfeit cards exist and can 
cause recording issues.  
We also highly recommend that the all cards are tested before taking them out into the field. 
Here is a simple testing procedure to determine if the card will function correctly: 

1.

 

Format the card in the transmitter. 

2.

 

Power cycle the transmitter. 

3.

 

Record at least 20 minutes of audio to the card with no time code source. 

4.

 

Look at the Main Screen it should still be recording in segment #1. 

5.

 

Playback and listen to the file. 

 

Media Capacity

 

The TRXLA3 can use Micro SD cards, up to 16 GB. While any size card will work we recommend using 4GB 
cards. All cards that are used in the TRXLA3 must be formatted in a 3 series transmitter to work properly, 
cards formatted in any other series transmitter will not record properly. Please note that regardless of the 
size of the card the onboard recorder will only be able to record up to 500 individual segments on any given 
card. 
Available recording times will depend on the selected modulation and are as follows:

Please note the transmitter will 

NOT

 record onto the card if: 

 

The card was not inserted before the TRX booted up. 

 

If the card was removed while the power was on. 

 

If LOW BATTERY is being displayed.   

 

Recording Format 

The media card is formatted using a FAT32 file system. While recording, the unit places all recorded audio in a 
single file on the media. The files generated by the recorder (.zax format) can only be recognized by Zaxcom’s 
ZaxConvert program. Using ZaxConvert will transfer the file to a Broadcast Wave or MP3 file. ZaxConvert is 
available to anyone for free from the Zaxcom website
