Ferrofish A32

32 in / 32 out AD/DA converter with coaxial and multi mode MADI and ADAT



The A32 is packed with analog and digital interfaces. In addition to the 32×32 balanced studio-quality analog inputs and outputs up to 192kHz, the A32 offers both ADAT and MADI – probably the most widely used digital audio interfaces available. In addition to the optical MADI I/O, another coaxial MADI interface is also added. Different modes allow redundant operation of both interfaces: If one fails, the other one is activated automatically. Speaking of redundancy: If desired, two power supplies can be connected to the device. All power supplies and interfaces are permanently monitored: In the event of a failure, an error message is output on the TFT screens.

Packed into a compact 1HU, the highly integrated converter is equipped with 32 x 32 balanced analog channels, brought out on 8 D-SUB connectors. They deliver studio levels up to +20dBu, individually adjustable in 1dB steps.

The sophisticated design, using low latency Cirrus Logic converters, accompanied with a temperature-compensated clock and jitter reduction PLL, guarantees best crystal clear sound up to 192kHz. The A32 is not just a converter, but thanks to its flexibility, using a sophisticated routing matrix, it is also a digital format converter for integrating the MADI and ADAT equipment.
