Professional Audio System Components Date printed: 29.11.01 E3 1 INTRODUCTION The individu al descriptions and application notes contained in this br o- chure are intended to acquaint designers and project engineers with the Studer Audio System Components. They allow to realize custom-tailored signal distribution, signal switching and amplifying systems to satisfy \ a l- most any individual requirement. Euro-Cards (1.915....) The backbone of the system is the so-called Euro-card, a circuit board measuring 100 × 160 mm, which comes in a great variety of different ci r- cuit configurations. Modular Sub-Cards (1.914....) Furthermore, there are the Modular Sub-Cards, small plug-in cards. Four of them can be accommodated on one Euro-size motherboard, allowing to make up a system which provides the ultimate in flexibi lity. Racks, Frames (1.918....) Matching 19 mounting frames and 19 sub-racks for Euro-cards with or without power supply are available as well as installation hardware. For prices please consult your local Studer distributor or contact: Studer Professional Audio GmbH Althardstrasse 30 CH-8105 Regensdorf Switzerland Phone: +41 44 870 75 11 Fax: +41 44 870 71 34 e-mail: sales@studer.ch We reserve the right to change the design and the performance specific a- tions of the products listed here as technical progress may wa rrant.

Professional Audio System ComponentsE4Date printed: 29.11.012 MSC SYSTEMTo provide highest possible flexibility for the designer of professional sound systems, Studer engineers have pursued a completely new concept. The Euro-card is a convenient circuit board as far as its size and its plug-in features are concerned. However, it often offers excess space for a par- ticular circuit. This has triggered the idea to utilize the Euro-card simply as a carrier (motherboard, order no. 1.915.770) for four smaller plug-in circuit boards, the Modular Sub-Cards (MSC). The 32 connections of the Euro-card are divided into 6 supply lines com- mon to the modular sub-cards, and 4 × 6 individual lines joining the plug- in sockets for each sub-card. The remaining 2 connections are used as separate bus lines, one of them leading to sub-cards 1 and 2, the other one to sub-cards 3 and 4, resulting in a total of 13 connections to each MSC. A small motherboard for only one MSC is available as well (order no. 1.914.500). A great variety of different circuits is available in form of MSCs, such as -Balancing amplifiers -Microphone pre-amplifiers -Speaker amplifiers -0-W input amplifiers -Limiters -Voltage controlled amplifiers (VCAs) -Relay sub-cards -High level input amplifiers -Line output amplifiers -1900 Hz signal generator/decoder -90° filter, stereo/mono -Flip-flop -Breadboarding card (0.1/2.54 mm grid) To meet the requirements of a system concept, a designer will be able to build individual circuits similar to working with a construction set: He ei- ther selects from the available circuits on Euro-cards or makes up his own Euro-card by simply arranging the most suitable combination of Modular Sub-Cards on the motherboard.
