Marc 4 DIGI


The Marc 4 Digi audio system provides four analogue inputs, four analogue outputs and a digital S/PDIF-I/O with two in- and output channels.

With high-quality 24bit/96kHz converters and sound optimised circuit design it offers professional audio quality on an especially good price basis. It is particularly interesting for users, needing only a limited number but high quality analogue audio in- and outputs and a digital interface.

The effective hardware design and a continually evolving high speed driver suite provide an undisturbed operation and minimal latency values in all software surroundings. This makes the Marc 4 DIGI particularly suitable for the working with software instruments and software samplers.

Flexible routing, start-stop synchronisation of all in- and outputs, sample exact transfer on all channels and direct undelayed controlling of the inputs (zero-latency monitoring) make the Marc 4 DIGI the perfect partner for ambitious harddisk-recording.

Like every member of the Marc-series, the Marc 4 DIGI is characterised by an easy installation and a steadily controlled high quality of manufacturing. It operates perfectly with Intel and AMD based systems.

The marc 4 DIGI can be expanded with an optional extender board providing an electrical digital I/O (S/PDIF and AES/EBU via rca and XLR) as well as a wordclock connector.


Four analogue in- and four analogue outputs in full duplex architecture, in connection with a sound optimised 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 work with low impedance and are 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.

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 high quality converters or signal processors can transmit data without quality-loss due to dithering or resampling. There is also a 2-pol digital input on the card which can be fed with e.g. the signal of a CD-ROM drive.


The Marc 4 DIGI 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 controlling 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 4 DIGI provides a complete list of drivers for Windows.

The continualy improved and expanded multi-client driver for ASIO, GSIF 2 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. That includes exact level metering, flexible monitoring and synchronisation settings.
