Founded in 1953 by Saul Bernard Marantz in Woodside, Queens, New York, Marantz has its roots in high-fidelity home audio. Saul Marantz built his first product — the Audio Consolette preamplifier — at his kitchen table in 1952, and the company quickly earned a reputation for exceptional sound quality through products like the Model 7 preamplifier and the Model 8 and Model 9 power amplifiers. Over the decades the brand changed hands several times, passing through Superscope, Philips, and D&M Holdings before the consumer hi-fi division landed under Sound United (later acquired by Masimo Corporation).

Marantz Professional, the brand's pro-audio division now operated by inMusic Brands, produces recording and broadcast equipment aimed at musicians, podcasters, journalists, and content creators. Its product line includes condenser microphones such as the MPM-1000 and MPM-2000U, portable solid-state field recorders like the PMD-661 and PMD-706, USB microphones for podcasting and streaming, and the Turret all-in-one broadcasting system. The professional division operates independently from the consumer hi-fi brand, maintaining its own product development and distribution under the marantzpro.com identity.

Marantz has 77 products cataloged on Equipboard, including Power Amplifiers, Condenser Microphones, and Home Amplifiers. Their gear is featured by 8 artists, with the strongest followings in Rock, Electronic, and Latin. Notable users include Josh Homme, Merzbow, and Charly García. Marantz's catalog spans the full price spectrum — from entry-level options to high-end flagships.
