4HM eyeing pro audio

UK MADI specialist “widens range and focus” with new website and products.

4HM, the British manufacturer of MADI interfaces, monitors and format converters, has signalled its intention to reposition itself in the wider pro audio sector.

With a new website, – for comparison, its previous URL was – and a slew of recent product announcements that have placed as much emphasis on audio infrastructure for live sound and installation as they do for broadcast, 4HM director Craig Lovell describes the company’s recent developments as focusing on “widening our appeal so that [we] are equally applicable in whatever environment MADI is found – whether it is broadcast, live sound or … installed sound.”

“Our primary focus when establishing 4HM was to provide unique interface solutions targeted towards the broadcast sector,” Lovell continues. “By focussing our efforts on providing broadcast MADI solutions we have gained a great deal of experience in developing products for use in highly demanding on-air applications – including for many of the world’s major sporting events, such as the London Olympics.

“However … MADI is an established format that covers many aspects of professional audio and is not unique to broadcast alone. Fortunately, the 4HM team has decades of experience in other market sectors, including live sound, fixed installation and recording – so, with our foundations now firmly set in place, we feel that the time is right to start expanding our product portfolio with the aim of providing interesting problem-solving MADI equipment for other market sectors.”

The company’s latest innovation is the “unique” MADI-MON, which permits the monitoring and interrogation of incoming MADI streams, including embedded data; full and simultaneous conversion of up to 64 channels to both AES/EBU and AES3id formats; and MADI to MADI format conversion.
