CAH

What CAH does

CAH Professional Sound Co., Ltd. is a Hong Kong-headquartered value-added audiovisual distributor and system integrator serving commercial AV markets across Hong Kong, Macau, and mainland China. Founded circa 1985 with a US subsidiary (CAH Audio Products, Inc., established 1990), the company holds exclusive or authorized distribution rights for roughly 13 premium professional audio and video brands, including Renkus-Heinz (beam-steering loudspeakers), Ecler (digital matrices, amplifiers), Tannoy (installation speakers), Lab Gruppen (amplifiers), Rane (DSP and multiprocessors), Opticis (fiber-optic AV extension), Williams AV (assistive listening and AI captioning), Insta360 (AI video conferencing), Hitachi (PTZ cameras), Klark Teknik, Mackie, Lubell Labs (underwater speakers), Biamp, and Bose Professional. CAH also markets its own CAH-branded wireless microphone system (U-3650D II) and mixing consoles (PRO-142/PRO-164).

CAH delivers complete AV system design, product specification, integration, and post-sale warranty service. Its technical stack spans Dante/AES67 audio-over-IP networking, RHAON networked audio control, EASE acoustic design, and AI-enabled collaboration endpoints. The business sells primarily through direct project-based B2B engagement to integrators, consultants, and end-clients across four verticals: education (e.g., Open University of HK, Fung Kai No.1 Secondary School, Wuxi Higher Normal School), corporate/financial (Bank of China HK Tower, bank HQ auditoriums), hospitality and retail (Galaxy Macau, Mira Moon Hotel, Chloe HK, Lululemon showroom), and performance/worship venues (Chi Lin Nunnery, St. Andrew's Church, Wujin Phoenix Valley Theater, Dalian Sport Center).

Revenue is generated via project-based hardware resale, system integration services, and warranty/maintenance contracts under a sales motion split between Hong Kong ([email protected]) and China ([email protected]). The company is privately held with no disclosed institutional investors, parent company, or funding rounds; pricing is not publicly disclosed on its website. Founded by a small team operating from a single Kowloon industrial building, it functions primarily as a multi-brand distribution and integration specialist rather than a manufacturer, with limited direct IP and modest proprietary product development concentrated in wireless microphones and mixing consoles.

Expansion highlights5 records

Broad incumbents

• Shure Incorporated: US-based microphone and wireless systems manufacturer with growing direct APAC distribution and conferencing products (Stem, IntelliMix); overlaps directly with CAH's CAH U-3650D II wireless mic and installed conferencing business.
• Biamp Systems: US-based professional audio manufacturer of DSP, amplifiers and conferencing endpoints; both a CAH distribution partner and a competing manufacturer with direct regional sales that can disintermediate local integrators.
• Bose Professional: Global pro-audio manufacturer whose products CAH distributes in HK; also sells direct and through competing integrators, making it both partner and competitive incumbent in installed sound.
• Harman Professional Solutions: Large multi-brand pro-audio group (JBL, Crown, Soundcraft, AMX) with global direct sales and APAC integrators; competes head-to-head with Renkus-Heinz/Ecler/Tannoy installations CAH specifies.
• AVI-SPL: World's largest commercial AV integrator, operating globally including APAC; competes with CAH on large enterprise/institutional bids but at far greater scale and with a much broader service portfolio.
• Sennheiser: German pro-audio and microphone manufacturer with global distribution and direct APAC presence; overlaps with CAH on wireless microphone and installed-sound product lines.
• Logitech (Logitech for Business): Global vendor of video-conferencing endpoints (Rally, MeetUp) competing with Insta360 and Biamp lines CAH distributes; relevant peer in the conferencing/UC end of CAH's portfolio.

Direct peers

• Vega Global: Singapore-headquartered AV system integrator and distributor serving enterprise, hospitality and government clients across APAC — the closest direct comp to CAH in business model, regional footprint, and customer segments.
• Snelling Business Systems: UK-based AV integrator and unified communications provider serving corporate, education and public-sector clients — closely comparable to CAH's project-based integration model and customer verticals.
• CCS Presentation Systems: US-based AV integrator serving corporate, education and government with design-build integration services — analogous operating model to CAH's enterprise/education/hospitality vertical mix.
