RME / HDSPe AIO Pro　PCI Expressオーディオインターフェイス

A PCI Express audio interface from RME, a company that makes professional-level audio interfaces. It comes with a 3-year Sound House warranty!

The HDSPe AIO Pro is the successor to the HDSPe AIO, a PCI Express audio interface that has gained immense support worldwide in the professional studio and broadcast markets. Continuing from the previous model, it is equipped with a variety of analog and digital input/output I/O, and has been completely redesigned as an advanced PCI Express card, with the latest technology being used generously.

By equipping a powerful desktop PC with the HDSPe AIO Pro, it is possible to achieve high-end, high-precision audio playback, editing, and AD/DA conversion. In addition to the fields of music production, broadcasting, system design, and research and development, the HDSPe AIO Pro can also be used as the core of live distribution systems, gaming PCs, and home theater systems, allowing you to enjoy high-resolution, clear, powerful sound.

The latest model in RME's 20-year-old Hammerfall DSP series, the HDSPe AIO Pro is an All-In-One reference audio interface with advanced I/O.

Next-generation PCI Express card reference
The HDSPe AIO Pro has been completely redesigned from the ground up based on the latest technology. All inputs and outputs, including SPDIF (coaxial) and AES/EBU (XLR), operate simultaneously. It also features RME's TotalMix FX routing mixer, which offers unparalleled flexibility, and SteadyClock FS, which suppresses jitter in external clocks with an accuracy of 1/1000th of a second.

The HDSPe AIO Pro inherits the technology of the high-end AD/DA converter “ADI-2 Pro”, and is equipped with the AK5572 and AK4490 reference processors. The analog input range (+24 / +19 / +13 / +4 dBu) also uses the circuit design of the ADI-2 Pro. Furthermore, by strengthening the output reference level (balanced: +24 / +19 / +13 / +4 dBu, unbalanced: +19 / +13 / +4 / -2 dBu), it is now possible to build more diverse audio systems. The HDSPe AIO Pro has a dedicated attenuator in the output section, which improves the signal-to-noise ratio and lowers the output impedance at low reference levels.

Another major highlight of the HDSPe AIO Pro is the newly developed headphone output, which delivers a very powerful and transparent sound. In addition, the mute relay, which includes a switchable output level, prevents unwanted noise from being generated in the headphone output and the analog XLR and RCA outputs when the computer is turned on.

PCI Express Interface
The HDSPe AIO Pro is not just a PCI technology adapted to PCI Express, but a genuine PCI Express solution developed from the ground up. It makes the most of the advantages of this new format to deliver a quantum leap in performance for multitrack audio.

Because PCI Express is a point-to-point connection, it can transfer data between two points without sharing the bandwidth with others.

The HDSP system, based on the PCI Express Base Specification v.1.1, is a 1-lane PCI Express endpoint device that supports a line speed of 2.5 Gbps. With a bandwidth of 5 Gbps, it is 3 to 4 times faster than conventional PCI. It provides a transmission rate of up to 500 to 200 MB/s in each direction through packet-based full duplex communication.

Zero CPU Load
The HDSPe AIO Pro performs many of its functions using the hardware DSP. This means that even when recording or playing back multiple channels, the CPU is not overloaded, and stress-free operation is achieved.

Low Latency Design
The HDSP series has established its position by achieving an astonishing and overwhelming low latency setting that was previously thought impossible with the concept of a sample buffer. In a computer-based music production and recording environment, latency (sound delay) that inevitably occurs can be set in 8 stages. It can be reduced to a minimum of 0.7ms.
