Ferrofish A32pro 32-Channel AD/DA Converter with MADI and ADAT

The Ferrofish A32pro, a 32-channel AD/DA converter, brings 32 balanced analog inputs and outputs, ADAT, and MADI together in one fanless 1U rack unit. A routing matrix links them all, so it also works as a format converter and signal router.

Analog Conversion

The 32 inputs and 32 outputs come out on eight D-Sub25 connectors with the Tascam pinout, and each channel’s level is set from -8 dBu to +20 dBu in 1 dB steps. The converters run at up to 192 kHz, clocked by a temperature-compensated oscillator and a jitter-reduction PLL.

Two balanced 1/4-inch main outputs on the back carry the same signal as the red headphone output, for monitor speakers.

ADAT, MADI, and Routing

Four ADAT ports in each direction carry all 32 analog channels at 48 kHz, or 16 at 96 kHz. Two SFP slots take MADI modules, and the A32pro ships with one optical multimode module that carries 64 channels at 48 kHz.

A second module, whether singlemode, multimode, or coaxial, makes the MADI link redundant: when one loses its signal, the unit switches to the other. MADI also carries MIDI for remote control. The matrix routes all 128 inputs to all 128 outputs in blocks of eight.

Screens, Monitoring, and Control

Four multitouch color screens show the levels of all 64 analog channels, the status of every digital interface, the clock and GPIO state, and the loaded preset. Two front headphone outputs, each on its own DAC path, monitor any input or output in mono, stereo, or mid/side.

The headphone outputs can also run together in a balanced mode for balanced headphones. The RemoteFish software for PC and Mac controls the A32pro over USB, MIDI, or MIDI-over-MADI. A GPIO port switches between four presets and signals lock, power, MADI, and temperature alerts.

Power and Expansion

Two screw-lock inputs take a second 12 V power supply for redundancy. Both supplies are monitored, and if one fails the unit switches to the other without interruption and shows a warning on screen. One supply comes in the box. A built-in DSP processes the routing, and two slots take optional DSP sticks for expansion.
