RME Audio HDSPe AIO Pro

All inputs and outputs are simultaneously operational, even SPDIF (phono) and AES/EBU (XLR). Of course TotalMix, the unsurpassed flexible routing mixer and SteadyClock FS, RME's sensational clock technology with maximum jitter suppression of external clock signals, are on board too. HDSPe AIO Pro also supports the optional TCO for synchronization to timecode (LTC/video).

The new HDSPe AIO Pro is based on the reference processors AK5572 and AK4490 derived from the high-end AD/DA converter ADI-2 Pro. The analog input range also uses the circuit design of the ADI-2 Pro (+24 / +19 / +13 / +4 dBu). In addition, RME has enhanced the outputs with additional reference levels (balanced: +24 / +19 / +13 / +4 dBu; unbalanced: +19 / +13 / +4 / -2 dBu) which allows even more versatile integration into audio systems. The HDSPe AIO Pro features a dedicated attenuator in the output section, resulting in an increased signal-to-noise ratio and a lower output impedance at low reference levels.

A further highlight of the HDSPe AIO Pro is the newly developed, powerful and extremely transparent headphone output. Thanks to mute relay including switchable output levels, there is no unwanted crackling noise at the headphone output and the analog XLR and RCA outputs when switching on the computer.
