PCIe Audio System

Seraph A3MWX

SERAPH A3 MWX - A new level of recording performance

The central of a modern professional recording studio has been created. Powered by the "BEAST" inside, the SERAPH A3 offers a full-range MIDI controllable DSP mixing desk with 5 pre/post aux-sums, up to 4 great sounding analog-feel EQs in every channel and a super-flexible routing – virtually latency-free and all without putting additional processing load on your CPU.

With 3 ADAT I/O and the TDM SyncBus used simultaneously to record AND playback all in all 64 channels, this sound system has clearly been designed for people confronted with big tasks. Even in S/MUX mode, allowing to record and playback 12 signals each at 96kHz, it still offers the same amazing amount of 64 mixer channels and the same amount EQ processing power.

Using the modern and super fast PCIe interface along with customized transfer functions, specifically designed and optimized for high quality and high speed audio transfer, the SERAPH A3 will turn any computer into a truly professional and versatile recording system …. And into much more...

The new cockpit of your studio: The BEAST

As the member of the SERAPH series it features the new BEAST DSP, which will make additional mixing or monitoring hardware obsolete. Even a patchbay can be spared. First of all, it includes a 64-2 channel mixer with one stereo aux and 3 more mono aux sums. These Aux sums are all pre/post assignable and can thus be used for headphone mixes or as effect sends. Furthermore every of the 64 channels provides an advanced filter section with

One low shelf EQ
Two peak EQs
One high shelf EQ

Flexible and Expandable:The TDM SyncBus

Using the TDM SyncBus the SERAPH A3 is a flexible basis for the realization of multichannel setups. Combinations with up to 3 more Seraphs or with any other SyncBus-compatible MARIAN sound system, allow setups with a number of channels according to your individual application or budget. The SyncBus enables all connected systems to share audio clock and start/stop information.

This unique feature ensures reliable recording of all the signals of the sound systems involved. More than that: Thanks to an intelligent bus management, TDM SyncBus compatible systems allow the transfer and exchange of up to 8 channels. The signals shared will appear in each mixer of each card. Even without another system the TDM SyncBus is a very useful tool, it allows putting EQs on a mixing sum or re-recording software application signals.

Fast and Reliable: Multi-client Driver Suite

Every SERAPH audio system provides support for Windows™ 2000/XP/Vista/7, Windows™ Server 2003/2008/2010 and Apple Mac OS X. The truly multi-client and continuously improved driver includes ASIO 2, GSIF 2, WDM with kernel streaming and real, non-emulated DirectSound support, delivering extrem low latencies for all software environments. Contrary to many competitive products, it allows to run several audio applications using the same or even different audio interfaces, parallel on the same computer system.

Well-structured settings, dialogues and menus of the driver along with simple to read and practical documentation in printed form, make it easy to setup this system and adjust it to the specific requirements of your studio. Of course all settings, including MIDI assignments and signal flow of mixer and routing can be saved in a file for total recall.

Powerfull and Future-proof: A perfect choice

The SERAPH A3 is available in two versions. For plain recording purposes the SERAPH A3 with its 3 ADAT connectors will serve perfectly in mainly all recording situations. The SERAPH A3 MWX provides an additional daughter board featuring 2 MIDI in- and outputs as well as a wordclock synchronization in- and output. It will be automatically recognized upon connection with the main card and does not require additional software installation.

The advantages of it are obvious: you can e.g. use the 2 MIDI inputs right away for controlling the BEAST with your preferred MIDI controller. Of course you can also hook up a master keyboard and sound expanders. The wordclock ports are ideal for advanced clock setups that allow independence of the clock signals of the ADAT ports. That means, you can also synchronize all external equipment featuring a wordclock input simply using the SERAPH A3 MWX as clock master. A helpful tool to manage clock signals is the included software clock status panel monitoring samplerates, lock status and possibly clock errors of all digital input signals.

Like every sound system by MARIAN the SERAPH A3 marks up due to its easy installation and steadily controlled highest manufacturing quality. This and the fact, that the SERAPH A3 is 100% engineered and assembled in Germany, make us confident enough to grant a full 5-year warranty.
