4HM: Updates to MA64 and MADI-MON

12 September 2014

4HM has released updated versions of its MA64 and MADI-MON devices here at IBC that are capable of operating at up to 96kHz. The units are also fully compatible with both the SMUX and high speed sample rate delivery protocols and are suitable for broadcast, live, installation and studio production environments.

The 4HM 64 channel MADI to multi-format AES converter, the MA64, and the MADI-MON have both received significant firmware updates following previous announcements that the 4HM product portfolio was to become more applicable to multiple market sectors. Both units are now fully compatible with 96kHz, 88.2kHz, 48kHz and 44.1kHz sample rates. Also, in a significant development, the MA64 and MADI-MON are now compatible with both the legacy SMUX and newer high speed MADI protocols.

The MA64 is a compact 1U MADI to multi-format AES converter that is capable of accepting with both fibre and coaxial inputs. The device is unique in that it can present 32 pairs (64 channels) of balanced AES/EBU and another 32 pairs of unbalanced AES3-id simultaneously for connection into consoles, routers or any other AES compatible device. MADI loop-through connectivity allows connection to downstream devices.

The MA64 also comes as standard with sample rate converters across all 64 channels, which combined with the comprehensive range of synchronisation options makes the unit very simple to wire into any existing infrastructure.

As well as being able to accept all of the listed MADI sample rates and protocols, the MADI-MON is able to monitor at each of the sample rates too.
