Designed to suit a wide range of content creators ranging from solo YouTubers to small video crews, the Deity BP-TRX is a flexible microphone recorder and wireless transmitter/receiver with timecode input and output capabilities. The compact, metal unit records to a microSD card, allowing it to be used as a standalone pocket audio recorder. In addition, you can pair it with additional BP-TRX units or a DUO-RX (both available separately) as part of a remote-controllable, camera-mountable, or bag-suitable digital wireless microphone system—with back-up recording capabilites if RF interference is encountered.

The compact BP-TRX easily clips to talent via a removable belt clip and features a locking 3.5mm input connector to accommodate the supplied omnidirectional lavalier microphone; a foam windscreen and lapel clip are also included. Input gain is adjustable from -12 to +36 dB, while the Guard Rail Analog Limiter keeps the signal from clipping and distorting if the source gets too loud—letting you place the recorder in the talent’s pocket without worrying about sudden level changes. The unit records audio at a 24-bit / 48 kHz resolution to a microSD card (available separately) with a maximum capacity up to 128GB.

The BP-TRX can be used as a digital wireless transmitter in the 2.4 GHz spectrum at a range of up to 328′ and paired with up to four additional BP-TRX units or a DUO-RX on the receiving side. To record from a BP-TRX in receiver mode, connect its locking 3.5mm output to your camera’s 3.5mm input using the included coiled cable. The unit can record to the microSD card while transmitting, giving you a clean audio take if there is interference in the wireless transmission.

The transceiver design allows for a wide variety of uses, including IEM and camera-hopping applications. What’s more, it enables remote control over numerous parameters on the transmitter, including input levels, low-cut filter settings, and RF output adjustments, all remotely from the receiver. You can even engage the on-board recording feature remotely without interrupting a take.

The onboard SMPTE timecode generator also outputs to the 3.5mm connector, allowing you to use it as a master clock for additional BP-TRX units and other devices that support timecode. A timecode sync and audio cable is included that lets you record both signals to an external device. The unit jam-syncs to incoming code via the same locking 3.5mm input used for the microphone.

Power is supplied by a built-in rechargeable battery, and the unit operates for up to 12 hours when used in transmitter or receiver modes, up to 21 hours in record mode, and up to 25 hours as a timecode-only box. The USB Type-C charging port also functions as a stereo audio interface for Mac and Windows computers. A charging cable and removeable 1/4-wave antenna are included.
