2 Introduction to Vienna The Vienna range of consoles continues the Soundcraft tradition in sound reinforcement, offering superb performance, ruggedness, versatility and value for money - equally at home in the theatre, on tour, in a conference hall, auditorium or place of worship. Vienna has been designed to provide oustanding sound quality and facilities, a clear and practical control surface and the sturdy frame with built-in handles offers the strength to survive many years, either as part of a fixed installation or `on the road. The console is available in 16, 24, 32 or 40 channel frame sizes, all with eight groups and eight stereo effects returns as standard. The console may be specified with eight VCA groups in addition to the audio groups, and may be fitted with optional dual Matrix Output modules in blocks of four where space is available. The Input module is available in VCA or standard versions, with a patented padless microphone amp, hi-pass filter and a four band equaliser specifically designed for live sound applications. The channel signal may be fed to eight auxilliary sends and routed to eight audio groups and left, right and mono mix outputs. Comprehensive muting and solo facilities are included and the signal is monitored by individual LED bargraph meters. The Group module comprises an audio subgroup with low-noise summing amplifier, PFL monitoring and routing to the main mix outputs, plus a full-featured stereo line input for use as an additional input or as an effects return. This stereo input has full muting and routing facilities, stereo image control and access to four of the auxiliary sends. On VCA consoles a similar module also houses a VCA group master fader. Comprehensive master and monitor functions are provided on the central Master module, including versatile talkback facilities either from the local engineer to desk outputs or as two way communication with a separate monitor console. The optional Dual Matrix output module allows additional submixes to be created from the group outputs, main mix outputs and a separate external input. These modules may be fitted in blocks of four where space is available. Vienna is designed to allow two consoles to be linked in a master/slave configuration, with opto-isolated control signals and balanced, buffered audio connections for maximum noise immunity. The interface allows two Vienna consoles, or one Vienna and one Europa console to be linked. Simplicity and clarity of operation is ensured by careful layout of controls, internally illuminated buttons and provision for three Littlelites on the top surface of the console, with an inbuilt dimmer.

7 Installation Vienna is designed for reliability, high performance and built to the highest standards. Whilst great care has been taken to ensure that installations are made as trouble-free as possible, care taken at this stage, followed by correct setting up will be rewarded by a long life and reliable operation. Warning! Before switching on your Vienna console, check that the mains voltage selectors on the power supply units are set to the correct mains voltage for your area, and that the fuses are of the correct rating. This is clearly marked on the case of the power supplies. Do not replace the fuses with any other type, as this could become a safety hazard and will void the warranty. Always ensure that you use the correct power supplies for your console. One CPS550 or CPS550-B unit and one CPS650 or CPS650-B unit are required for the 16, 24 and 32 channel consoles, while the 40 channel console requires one CPS550 or CPS550-B and one CPS750 or CPS750-B. Different configurations of power socket are used for each supply to prevent incorrect connection. Wiring Considerations A For optimum performance it is essential for the earthing system to be clean and noise-free, as all signals are referenced to this earth. A central point should be decided on for the main earth point, and all earths should be `star-fed from this point. It is recommended that an individual earth wire be run from each electrical outlet, back to the system star point to provide a safety earth reference for each piece of equipment. B Install separate mains outlets for the audio equipment, and feed these independently from any other equipment. C Avoid locating mains distribution boxes near audio equipment, especially tape recorders, which are very sensitive to electro- magnetic fields. D Where possible ensure that all audio cable screens and signal earths are connected to ground only at their source. 6 Installation

8 Connections Wiring conventions The standard Vienna console uses two different types of audio connector, 3 pin XLR (top diagram) and 1 4" three pole (`A gauge or stereo) jacks. The latter are used in several configurations, as shown below. Two EDAC multiway connectors are included for linking to other Vienna or Europa consoles and three BNC connectors are fitted feed Littlelites. 1/4" A Gauge Stereo Jack Plug used as balanced input: line inputs, 2 Track B returns, insert returns 1/4" A Gauge Stereo Jack Plug used as ground compensated output: Input & Group insert sends 1/4" A Gauge Stereo Jack Plug used as balanced output: mix insert sends, channel direct outputs 1/4" A Gauge Stereo Jack Plug used as a stereo output: headphones Installation 7
