Automixer Digital Modulation Encrypted Audio Intermodulation Resistant Internal Recording Timecode ZHD Modulation

One System, No Compromises

DCiRX is a next-gen audio solution that integrates a receiver, recorder, automixer, and USB-C interface into a compact device designed for filmmakers, broadcasters, and content creators.

Powered by our Narrow Band Direct Conversion technology, DCiRX receives UHF audio from a single mono or stereo transmitter while simultaneously supporting a direct input for 5V lavalier or 48V phantom powered microphones.

A built-in 4-track recorder captures up to 3 ISO tracks plus 1 automix with timecode in 32-bit float or 24-bit fixed. A USB-C interface connects to mobile, computers, or USB-C cameras, delivering 4 channels of audio with timecode.

Dedicated connections include a balanced TA5 output, locking headphone and timecode jacks, dual SMA antennae connectors, and an OLED screen for easy navigation.

Narrow Band Direct Conversion

Advanced Narrow Band Direct Conversion technology makes DCiRX resistant to nearby RF sources, including cell phones, walkie-talkies, and 2.4 GHz interference, resulting in crystal clear production audio.

UHF Spectrum

DCiRX operates across 470 to 698 MHz UHF for reliable range and consistent performance when every take counts.

Silencing RF Noise

A tunable tracking front-end filter improves intermodulation resistance, extends operating range, and ensures stable RF performance. Adjustable in 1 MHz steps, the filter provides precise band selection for rejecting unwanted signals.

Additionally, Zaxcom’s own digital dropout compensator intelligently reconstructs any missing audio data to maintain continuous, production ready audio.

Intelligent Frequency Scans

An autoscan feature quickly analyzes RF conditions and locks in the optimal frequency, reducing congestion without manual tuning.

Stand-Alone Wireless Receiver

DCiRX advanced RF design delivers exceptional range and stability whether mounted on a camera, sound bag, cart, or as a dedicated receiver node in complex production setups.

Stereo Link Receiver

As a stereo link receiver DCiRX delivers high quality audio to camera. Wireless audio and embedded timecode is sent via a dual balanced output allowing seamless integration in any workflow.

Real World Workflow
Production audio is fed to a Zaxcom TRXCL5 camera link transmitter and then sent wirelessly to the DCiRX. A balanced output feeds audio and timecode to camera.

IFB Receiver

Deliver low-latency audio to directors, producers, and crew using UHF instead of crowded consumer frequency bands. Simply tune in and monitor via headphones.

32-Bit Float Internal Recording

Record 32-bit float or 24-bit fixed broadcast WAV files with timecode to internal microSD for easy offloading and transfer.

Internal recording supports up to 3 ISO tracks plus 1 automix track from a single or multiple audio source whether wireless, wired, or both.

DCiRX can also transmit wireless audio while simultaneously recording internally, creating a redundant recording path.

Real World Workflow
•1x External Microphone
•1x Wireless Transmission (mono or stereo)
•1x Automix track
Note: Zaxcom stereo transmitters provide two audio signals

Ideal or follow car setups, plant mics, or when wireless transmission is not possible. Stash a DCiRX with a mic and hit record.

4-Track Internal Recorder

With a built-in 4-track recorder, DCiRX records 3 ISO tracks plus 1 automix track with timecode in 32-bit float or 24-bit fixed to microSD.

Internally recording supports wireless and wired mics with simultaneous internal recording.

Real World Workflow
•1x External Microphone
•1x Wireless Transmission (mono or stereo)
•1x Automix track

Sound cart out of range? No problem. Connect a Zaxcom wireless transmitter to DCiRX and let the internal recording do the rest.

USB-C Audio Interface

For creators, podcasting, and streaming, DCiRX doubles as a 4-channel interface for mobile, computers, and USB-C camera setups.

DCiRX supports up to 3 ISO tracks plus 1 automix with timecode for flexible, production-ready audio.

Real World Workflow

Cinema Sound elevated

Whether shooting a film, documentary, series, or creating content, DCiRX is your versatile audio companion. A dual balanced 2-channel output delivers mic or line level audio adjustable up to +12 dBu for easy camera integration via TA5 or adapters. This allows DCiRX to support multiple audio signals to camera, whether from an external microphone, a talent lavalier, or a full production mix.

Real World Workflow   

For cameras like the ARRI Alexa Mini, Mini LF, or Alexa 35 that lack 48V phantom power, DCiRX allows use of external shotgun mics by providing phantom power. DCiRX can power a shotgun mic but also simultaneously receive wireless audio and route both signals directly to camera.  

Potential Setup
DCiRX mounted to camera supports:
•1x External Microphone
•1x Wireless Transmission (mono or stereo)
Note: Zaxcom stereo transmitters provide two audio signals

Audio output options from DCiRX to camera:
•1x External Microphone
•1x Wireless Transmission
Note: Wireless audio can be as simple as a talent lavalier or the full production mix
