A32

32 x 32 AD/DA <> MADI <> ADAT Converter

Smart converter. Done right.

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!

A32: compact, flexible, affordable.

Redundant MADI I/O

The MADI I/O of the A32 is provided as optical fiber ports (SC Multimode connector) and coaxial BNC. 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

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

Internal Routing Matrix

The A32 provides a sophisticated internal matrix for the free routing and splitting of all 128 Ins to all 128 Outs in blocks of 8 channels. The headphone output allows it to monitor every mono or stereo I/O plus one of 7 submixes directly from the front of the unit.

High Performance DSP

The Analog Devices Sharc DSP processor is optimized for audio processing. In the A32 Dante it is used for routing, mixing and effects of all channels. The architecture with 2 cores at 400MHz and floating-point unit allows the parallel processing of all audio data in highest precision.

Redundant Power Supply

For reliability, the A32 can be powered by two power supplies. Both power supplies are permanently monitored, and switched without interruption in case of failure. Warning message is shown on the screen to be able to react on this failure.

Flexible Remote Control

A comprehensive remote software for PC and MAC is available to control the A32 Dante. In addition to USB, the A32 can also be connected via MIDI and MIDI over MADI. All Ferrofish devices are automatically detected and listed in the software.
