FERROFISH A32

FERROFISH A32

32x32 AD/DA converter ADAT/MADI

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. Even operation of the A32 is done without any compromise, almost self explaining, as with all our products: A total of four TFT screens show the levels of all 64 channels, it can’t be done better. Controlling the unit also benefits from the screens: a sophisticated help system built into the device provides context-sensitive help for the selected function at all times. Control on the PC is of course also possible via USB, MIDI or MIDI over MADI. The headphone can be connected to any analog or digital input or output: ideal for control or monitoring. For complex tasks, a mix especially for the headphones can be created using all available channels, and stored in up to seven mix presets. The A32 Dante – a version with an additional 64 x 64 Dante channels – is also available. The flagship A32 brings our 10 years of experience in converter technology to the point, uncompromising to the last detail. All packed in only 1HU rack housing, of course fanless!
