Marantz Professional is the pro audio division of the Marantz brand, producing field recorders, podcast and studio microphones, broadcast gear, and wireless systems. The division is owned by inMusic Brands and operates independently from the consumer Marantz hi-fi line. It is best known for the long-running PMD series of portable solid-state recorders — models such as the PMD620, PMD660, PMD661, and PMD670 — which became a standard tool for radio journalists, field reporters, podcasters, and documentary recordists.

The catalog spans handheld flash recorders, rackmount CD and cassette units like the PMD-300CP, USB condenser microphones aimed at the podcasting market, and playback gear for broadcast and installation use. Products typically emphasize utilitarian, single-handed operation, XLR inputs, and format flexibility (WAV and MP3), reflecting the division's focus on spoken-word and field-recording applications rather than music production.
