Broadcast Quality Sound

We wanted to create an XLR transmitter that would be truly unique and different. It's compact form factor makes it lightweight for boompoles. Combine it with a shotgun microphone with it's a built in recorder and headphone jack you don't even need any other sound gear to capture great audio.

HD-TX Features

  • Transmit and record simultaneously*
  • Guard Rail Analog Limiter
  • 1.3″ OLED display
  • Record 24-bit/48kHz WAV files to MicroSD card
  • Switchable between the XLR input and 3.5mm Mic/Line input
  • +48V Phantom Power
  • ~10hrs of battery life at 100mW
  • ~8hrs record time on a 8Gb MicroSD card
  • Headphone jack for live monitoring and listening to playback
  • Firmware updatable

*Deity HD-TX units sold inside the USA can only transmit and record when +48V and the XLR input have been selected. Only internationally sold units will feature the ability to transmit and record simultaneously using the 3.5mm input.

Record Safely

The HD-TX features 4 safe guards to make sure the audio you recorded doesn’t currupt.

  • Permanent built-in battery prevents accidental shutdowns due to an opened battery door like on other recorders
  • Automatically stops recording and saves your file when the power down command has been sent
  • Predictable battery metering sends the power down command to your recorder long before your battery dies preventing mid-roll power outages
  • Lock screen prevents the stop button from accidentally being pressed mid-record

More Than XLR

The HD-TX also features a locking 3.5mm jack so you can use it as a body pack transmitter too in a pinch. Just use the included belt clip sleeve to gain the ability of mounting the HD-TX to your talent.

Compact And Lightweight

The HD-TX just as small as industry standard XLR transmitters but comes in at least 40 grams lighter than the best selling XLR transmitters. And when mounted on an extended boom pole, ever gram adds up, now you can choose an easier to boom transmitter.

On-Board File Management

The HD-TX allows you to playback files, rename them, and delete takes. File names are determined by the USER ID assigned to the HD-TX so if multiple units are being used file management in post production will be easier to keep organized. You can also format your MicroSD card and transfer files to your PC all in the menu of the HD-TX.

Record +120 Hrs Of Audio

You can record days of audio before you have to swap MicroSD cards.

Sounds like your screen lock has engaged. Press and hold the Up and Down buttons at the same time for 3 seconds to unlock your screen.

Add some High-Frequency Boost in the TX menu to increase the high frequency making it sound brighter and more clear.

Make sure when you are using transmitters that are paired to different receivers that you use the USB-C Master Slave Sync cable. Plug in the USB-C Master Slave Sync cable to both receivers to sync them up. This will help prevent your transmitters from hopping to the same frequency at the same time.

Make sure your antennae are screwed all the way on. Try to make sure the bend of the transmitter’s antenna is away from the human body – this alone will increase the efficiency of the transmitter by another 25%. Also make sure you are not standing within 5 meters of the WiFi router – a lot of WiFi routers have bad RF spray that affects all of the 2.4GHz channels. Keep your cell phone away from your BP-TX, it will affect your signal range. Lastly make sure you don’t use the same USER ID on more than one BP-TX. The USER ID is used to encrypt and decode your signals and having multiple units with the same USER ID will confuse your receiver’s ability to decode the signal.

Make sure you are using a USB drive that is formatted for FAT32. Also insert your drive after you’ve entered the update menu but before you upload the update file. Make sure you have placed the .bin files on the root of the USB drive.

Some brands of lavaliers do not recommend using their lavaliers with 100% digital systems like the Deity Connect or the Sennheiser AVX. This is due to their lavaliers’ lack of shielding in the cable. You can either reduce the RF Power on your TX to see if this helps reduce the interference noise or change to a lavalier that was designed for use with a digital wireless system.
