Marantz Professional PMD-750 – Camera-Mount Digital Wireless System...
Product Overview
The Marantz Professional PMD-750 is a complete 2.4 GHz digital wireless system built for DSLR camera operators, run-and-gun videographers, and ENG crews who need reliable, uncompressed audio without the complexity of licensed RF bands. The system pairs a beltpack transmitter and a camera-mount receiver with an omnidirectional lavalier microphone, delivering 96 kHz / 24-bit audio at up to 100 feet of operating range. Operating in the 2.4 GHz ISM band keeps the system clear of TV and UHF radio interference common in broadcast environments. The compact receiver mounts directly to a camera hot shoe or rig, making this a practical single-operator wireless lavalier solution for documentary, interview, and field production work.
Product Description
The PMD-750 is a self-contained wireless audio package designed for camera-mounted deployment. The PMD-750R receiver is light enough at 3.2 oz to sit on a camera hot shoe without affecting balance, and it accepts a locking 4-pin mini-XLR output cable to connect cleanly to a camera body or external recorder. The PMD-750T beltpack transmitter accepts the included omnidirectional lavalier microphone via the same locking 4-pin mini-XLR connector, preventing accidental disconnection during active shoots.
Audio quality is a standout specification for this price tier: 96 kHz / 24-bit uncompressed transmission with a dynamic range exceeding 110 dB and THD below 0.01% means the wireless link introduces no meaningful degradation relative to a wired lavalier connection. System latency is 3.5 ms, which is negligible for video production workflows. Both units display operating status on sunlight-readable OLED screens, and 16 selectable channels allow multiple PMD-750 systems to run simultaneously without coordination headaches on a multi-camera set.
The receiver can pair with two transmitters simultaneously, enabling a two-person interview or dialog capture with a single receiver on camera — the second transmitter (PMD-750T) is available separately. All accessories are included: foam and fuzzy windscreens, a right-angled receiver output cable, a cold/hot-shoe adapter, and two belt clips. Both units run on 2 AA batteries, keeping power sourcing simple in the field.

- Locking 4-Pin Mini-XLR Connectors — Both the transmitter input and receiver output use locking mini-XLR, preventing cable drop during active field production.
- Dual-Transmitter Pairing — One receiver pairs simultaneously with two transmitters, supporting two-person interview or dialog capture without a second receiver (additional transmitter sold separately).
- 16 Selectable Channels — Allows multiple PMD-750 systems to operate concurrently on a multi-camera production without frequency conflicts.
- Sunlight-Readable OLED Displays — Both transmitter and receiver show operating status on OLED screens visible in direct outdoor light.
- Omnidirectional Lavalier Microphone Included — Electret condenser capsule, 20 Hz–20 kHz response, sensitivity -38 dB, equivalent noise 25 dBA, and 130 dB max SPL for voice capture in variable environments.
- Complete Accessory Kit — Ships with foam and fuzzy windscreens, right-angled receiver output cable, cold/hot-shoe adapter, and two belt clips.
Typical Applications
- Broadcast studio — single-camera and multi-camera dialog capture for news and interview formats

Frequently Asked Questions
Q: Does the PMD-750 require a license to operate?
No. The PMD-750 operates in the 2.4 GHz ISM band (2.401–2.483 GHz), which is license-free in the United States and most other countries. No FCC coordination or site licensing is required, making it straightforward to deploy across multiple locations.
Q: How many PMD-750 systems can run simultaneously at one location?
The receiver offers 16 selectable channels. In practice, the number of simultaneous systems depends on local RF congestion in the 2.4 GHz band, which is also shared by Wi-Fi and Bluetooth devices. In environments with moderate Wi-Fi traffic, multiple PMD-750 systems can typically coexist with careful channel assignment.
Q: Can I use the PMD-750 receiver with a transmitter other than the PMD-750T?
No. The PMD-750R receiver is designed to pair exclusively with Marantz Professional PMD-750 series transmitters — the PMD-750T beltpack and the PMD-750TA plug-on transmitter. It is not compatible with transmitters from other manufacturers.
Q: What camera output does the receiver connect to?
The PMD-750R outputs audio via a locking 4-pin mini-XLR connector. The included right-angled cable adapts this to a 3.5 mm TRS connection compatible with most DSLR, mirrorless, and camcorder audio inputs. For professional cameras with XLR inputs, an additional adapter cable is required.
Q: Can the PMD-750TA plug-on transmitter work with this system?
Yes. The PMD-750R receiver supports simultaneous pairing with two transmitters. The PMD-750TA (sold separately) converts any wired XLR microphone into a wireless source, allowing you to run a lavalier on the beltpack and a handheld or shotgun mic on the plug-on simultaneously through a single camera-mount receiver.
Q: What is the warranty on the PMD-750?
The Marantz Professional PMD-750 carries a one-year limited warranty from the date of original purchase. Contact Marantz Professional support or your authorized dealer for warranty service and repair options.
Q: Is the PMD-750 suitable for broadcast studio environments?
The PMD-750 is designed for field production and camera-mount use. It is well-suited to interview-format and documentary-style broadcast capture. For fixed broadcast studio installations requiring rack-mount receivers, diversity antennas, or licensed UHF frequencies, a professional broadcast wireless system may be more appropriate.
