What Inter-M Co Ltd does

Inter-M Corporation is a South Korean public address (PA), professional audio, and integrated communications equipment manufacturer founded in 1983 and listed on KOSDAQ since December 27, 1995 (ticker: 17250). The company designs, manufactures, and sells hardware systems for institutional and commercial customers, with a product portfolio organized into four main categories: Public Address (network broadcasting, IP speakers, the 6000 System audio matrix, EVAMATRIX emergency voice alarm, amplifiers, and PA speakers), Professional Audio (mixers, processors, DSA/DPX amplifiers, point source loudspeakers, and CLA/NLA line array systems), Transmission Solution (network converters and audio-over-IP modules), and supporting accessories. Technical architecture centers on Dante-enabled network amplifiers, DSP processing, and integrated audio/video/communication control via web-based GUIs and proprietary Windows software; the company integrates with AMX/Crestron building automation systems via RS-232C and supports VoIP paging.

The company serves four primary vertical markets: educational facilities, commercial buildings, cultural venues, and sports/gymnasium facilities, with use cases spanning announcements, emergency broadcasting, BGM, paging, and performance sound reinforcement. Inter-M monetizes primarily through hardware sales of professional audio equipment and system integration (supply and installation) for institutional projects, operating a direct sales motion via its website (inter-m.net) with quote-based B2B pricing and international distribution through trade shows such as INTERSEC (Dubai, 2025) and InnoTrans (2024). Production occurs at its Yangju headquarters and Hongjuk Factory in Gyeonggi-do, with a related Chinese production plant — Inter-M (Dongduan) Electronics Co, Ltd. — supporting manufacturing. The company holds EN54-16, ISO IRIS, and 2026 NET (New Excellent Technology) certifications, holds multiple patents in emergency broadcasting and audio networking, and employs 278 personnel under CEO CHO NAMYONG.

Revenue and financial figures are not publicly disclosed in available data; no public or partner-facing developer API exists. The company is positioned as a mid-sized, export-adjacent Korean industrial audio firm with a self-described "Korea's No. 1" PA brand, an installed base spanning 40+ years, and a 2026 pivot toward AI-driven emergency broadcasting solutions.
