RME turns Pro

With the advent of the HDSPe AIO Pro PCI Express interface card, RME has announced the successor of the HDSPe Audio Interface Card (AIO). Like its predecessor, all inputs and outputs can be used simultaneously but the Pro version has been designed for studio and broadcast applications offering a total of 30 channels (14 input, 16 output), each with a maximum of 24-bit/192kHz. The PCI Express audio interface also offers analogue stereo input and output, an additional headphone output, ADAT, SPDIF and AES/EBU I/O and one MIDI I/O.

The HDSPe AIO Pro is based on the reference processors AK5572 and AK4490 derived from the ADI-2 Pro AD/DA converter. In addition, RME has enhanced the outputs with additional reference levels to allow more versatile integration into audio systems. The HDSPe AIO Pro also includes a dedicated attenuator in the output section, resulting in an increased signal-to-noise ratio and a lower output impedance at low reference levels.

With the SteadyClock FS, the HDSPe AIO Pro features the latest clock and jitter rejection technology from RME. A further highlight of the HDSPe AIO Pro is the newly developed transparent headphone output. The mute relay includes switchable output levels that can remove the crackling noise at the headphone output and the analogue XLR and RCA outputs when switching on the computer.

Firmware update 2.0.0 has also been released for the M-32 Pro devices to increase AVB channel count from 64 previously (four streams) to 128 (eight streams) and allow single-channel routing across all inputs and outputs. The upgrade includes a new web remote interface and an enhanced JSON API for remote control over any type of network connection. The AVB implementation has been enhanced to be fully compatible with Milan.
