4HM has unveiled the AM64 multi-format AES-to-Madi converter, offering fibre and coaxial transport for broadcast applications

The 1U-high unit accepts up to 64 channels, comprising 32 stereo pairs of AES/EBU or AES3-id audio (selectable from the front panel) and provides format conversion to Madi with switchable sample-rate converters. The Madi data is presented on either coaxial or fibre outputs. The AM64 is compatible with both single-mode and multi-mode fibre and provides peace of mind with a redundant power supply.

On the rear of the AM64 are an ST fibre connector and a BNC providing the Madi output. Inputs by way of four 25-way D-sub connectors, handling balanced digital audio, and a single 37-way D-sub for unbalanced digital audio. There is a sync reference input on BNC and derived word clock and AES clock outputs both also on BNC.
