The A32pro is a worldwide unique solution to convert and route all important PRO-Audio formats with the highest possible I/O density in a single HU rack device: Analog, MADI and ADAT – all with up to 192 kHz.

The incredible flexible converter provides 32 balanced analog I/Os in D-Sub25 format with pro studio levels up to +20dBu – adjustable in 1 dB steps.

High-Quality analog conversion: with the latest high-performance low-latency converter generation from ESS, the device sets a new milestone for multi-channel conversion. Combined with a temperature-compensated high-precision clock and an active jitter reduction hardware design, the 388-channel behemoth delivers an exceptional detailed sound.

A total of four multitouch TFT screens show the levels of all 64 channels. A sophisticated help system provides context-sensitive help for the selected function at all times.

Remote Control by the RemoteFish App (PC and Mac) is also possible via USB (USB-over-MIDI), MIDI, MIDI-over-MADI.

MADI: The A32pro comes with two redundant MADI SFP ports (64 fully routable channels). Any combination of optical and/or BNC SFP modules can be used. The device ships with a single optical Multimode I/O module, supporting 64 channels at 48 kHz.

ADAT: 2 x 4 TOSLINK ports can convert all 32 analog I/Os.

The A32pro provides a Word Clock I/O and a classic MIDI I/O for embedding signals and remote control of the unit. On top of it: GPIO, intuitive one-knob control, Preset Management, Panel Lock and a powerful cross-format routing matrix (see below). The A32pro series can also operate as a highly flexible digital audio signal router.

Additionally two headphone outputs on the front and an analog stereo output on the back can be used to monitor any channel, sending it to several destinations.

All in all the fan-less, small footprint Smart Converter & Routing system is a huge problem solver for studio and live sound applications. The efficiency puzzle for live, studio and broadcast is solved – finally.

Redundant MADI I/O

The MADI I/O of the A32pro is provided as two redundant SFP ports. The device ships with an optical Multimode SFP. SFP modules with coaxial MADI I/O are available on request. The I/O support MADI delay compensation, 64- and 56-channel formats and port redundancy. MADI streams can be used to send and receive embedded MIDI messages.

4 x TFT Display with Touch Control

Four high-resolution TFT displays provide detailed level information for 2 x 32 analog signals – allowing the overview of the signal flow in and out of the unit. The innovative on-board contextual help, much loved by Ferrofish users, allows it to use the high-tech device, without reaching for the manual.

Internal Routing Matrix

The A32pro provides a sophisticated internal matrix for the free routing and splitting of all 128 Ins to all 128 Outs. The headphone outputs allow it to monitor every channel directly from the front of the unit. Submix Monitoring will be possible with a later firmware version.

High Performance DSPs - expandable

The high quality analogue circuit is accompanied by powerful DSPs. A high-performance Sharc-DSP with floating point calculation and 80-bit accumulator processes all audio data with unmatched accuracy.
The DSP platform is ready for expansion: two slots for optional DSP Sticks open a whole new world for multichannel audio and signal processing updates in the future.

Redundant Power Supply

The A32pro provides two automatically switch-over power supplies for worldwide operation. Both external power supplies can be replaced in seconds and even switched during operation without interruption. This way the device does not need to be sent in for repair if a power supply fails.
Note: The A32pro ships with a single US power supply. A second PSU for redundancy is available from Synthax USA.

Flexible Remote Control

The A32pro can be remotely controlled via the RemoteFish app (Win/Mac) with these connections from the host computer: MIDI, MIDI-over-MADI and USB.
MADI audio streams can be used to send and receive embedded MIDI messages.
