Marc 2


The four channel Marc 2 is the solution for the standard audio transfer inside and outside the computer and offers high-end-features for a favourable price. The analogue and digital interfaces, including an internal connector for a CD-ROM drive with digital audio output, are characterised by a wide range of driver support and very low latency values..

With high-quality 24bit/96kHz converters and a sound optimized circuit design it offers professional audio quality.

The effective hardware design with no-interrupt architecture and a continually evolving high speed driver suite provide a undisturbed operation and minimal latency values in all software surroundings. This makes the Marc 2 particularly suitable for the work with software instruments and software samplers.

Flexible routing, start-stop synchronisation of all in- and outputs, sample exact transfer on all channels and direct delay-free controlling of the inputs (zero-latency monitoring) make the Marc 2 the ideal partner for ambitious harddisk-recording, as well.

Like every member of the Marc-series, the Marc 2 is characterised by an easy installation and a steadily controlled high quality of manufacturing. It operates perfectly with Intel and AMD based systems.


Analog: Two analogue in- and two analogue outputs in full duplex architecture in connection with a sound optimized circuit design provide professional audio specifications. A/D and D/A converters of the well-known manufacturer AKM, as well as the complete hard- and software architecture are designed for 24bit/96 kHz operation.

The analogue I/Os are lead outside via 6,3mm stereo TRS jacks. The outputs are low impedance and therefore suitable for headphones.

Software controlled input amplifiers allow incoming signals to be boosted to +18 dB or cut to -40 dB. All input channels can be routed to any output - even if several audio systems of the same type are installed. The monitoring modes on-punch and on-rec are supported by all input channels.

Digital: The card provides an optical stereo input in TOS-/Link format, operating in S/PDIF format with up to 24bit and 96 kHz. This way external high quality converters or signal processors can transmit data without quality-loss due to dithering or resampling. Additionally the card provides a 2-pol digital input which can record e.g. the signal of a CD-ROM drive.

Multi-card-operation / cascading

The Marc 2 is capable of easily being cascaded to other marian audio systems. This way up to four members of the Marc-series can be combined to a very affordable multi-channel system, in which only one single driver manages the controlling of all parameters of the same Marc type. In connection with the syncbus it takes care for perfect synchronisation of all individual systems and makes all marc systems available to one ASIO-software application.

Driver suite

The Marc 2 provides a complete list of drivers for windows.

The continualley improved and expanded multi-client driver for ASIO, GSIF 2, WDM with kernel streaming and real, non emulated DirectSound support, provide minimal latency values for all software surroundings. Modular and clear driver dialogues enable the manipulation of many parameters and the display of all in and outputs. This includes exact level metering, flexible monitoring and synchronisation settings.
