Marantz Professional PMD-750T – 2.4 GHz Beltpack Transmitter with Lavalier

Product Overview

The Marantz Professional PMD-750T is a 2.4 GHz beltpack transmitter paired with an omnidirectional lavalier microphone, designed to expand the PMD-750 wireless camera-mount system to two-channel operation. It transmits two independent mono signals or a stereo pair, making it a direct solution for interview setups, documentary shoots, and on-camera dialogue capture for two subjects simultaneously. Operating on frequency-hopping spread spectrum (FHSS) technology in the 2.4 GHz band, the PMD-750T pairs automatically with the PMD-750 receiver and selects the cleanest available channel without manual frequency coordination. At 2.9 oz, it clips to a belt or waistband without adding perceptible weight to the talent.

Product Description

The PMD-750T uses 2.4 GHz FHSS wireless technology to maintain a stable RF link up to 100 feet (30.5 m) in line-of-sight conditions. The included omnidirectional lavalier microphone connects via a locking 4-pin mini-XLR (TA4) jack that prevents accidental disconnection during movement — a practical feature when the talent is active on set. The OLED display provides clear readout of gain level, battery status, and channel information and remains readable in outdoor sunlight without needing to shield the screen.

Power comes from two standard AA batteries, eliminating proprietary battery packs and reducing operating costs in field production scenarios. The transmitter ships with both foam and synthetic-fur windscreens, addressing wind noise in outdoor or high-airflow environments without requiring additional accessory purchases. The PMD-750T is the correct expansion unit for anyone already running the PMD-750 base system who needs to capture a second audio source on the same receiver.

Key Features

• 2.4 GHz FHSS Wireless — Frequency-hopping spread spectrum operation provides interference resistance without requiring manual frequency coordination in congested RF environments.
• Automatic Pairing and Channel Selection — The transmitter pairs with the PMD-750 receiver automatically and selects the cleanest channel, reducing setup time before a shoot.
• Omnidirectional Lavalier Microphone Included — The bundled lavalier captures speech from any angle, suitable for clip-on placement at the collar or lapel without requiring the subject to stay on-axis.
• Locking 4-Pin Mini-XLR Mic Input — The TA4 connector locks in place, preventing the lavalier cable from pulling free during active movement or clothing adjustments.
• Sunlight-Readable OLED Display — Provides clear status information on gain, battery level, and channel in outdoor shooting conditions where LCD screens wash out.
• AA Battery Power — Uses two standard AA batteries, which are universally available and interchangeable across production kits without dedicated charging infrastructure.
• Dual Windscreen Kit — Ships with both foam and synthetic-fur windscreens, covering both moderate and high-wind outdoor recording scenarios out of the box.
• Two-Channel System Expansion — Extends the PMD-750 wireless system to capture two independent audio sources simultaneously on a single receiver for stereo or dual-mono recording.
