MC-1 and MC-1.1 are multifunctional, high performance digital audio format converters for S/PDIF and AES/EBU. Due to the increasing number of devices with S/PDIF and AES/EBU interfaces found in every studio environment more and more often, a problem of different transmission formats and interface standards occurs mostly when those devices should exchange their digital audio data. At this point MC-1 and MC-1.1 come in and help to convert both digital audio formats and their corresponding interface standards in different ways. MC-1 + MC-1.1 COMMON FEATURES: • S/PDIF optical/coaxial and AES/EBU interfaces in one box. • Uni-directional format conversion from 32.0kHz to 192.0kHz between • S/PDIF and AES3/AES11. • Simultaneous format conversion to all output formats while allowing • the original signal to pass through. • Signal improvement by low-jitter PLLs. • ADAT™ transfer through AES/EBU lines. • NONE-PCM and DTS bitstream detections. • SCMS processing and status analysing. • Easy configurable. • User's settings will be stored after switching-off. • Rack space saving 1/2 19" housing allowing for mounting two devices • in one rack unit. • Built-in international power supply. ADDITIONAL FEATURES FOR MC-1.1: • Bi-directional format conversion from 32kHz to 192kHz. • ADAT™ signal splitting + line extension. • S/PDIF optical/coaxial + AES/EBU signal splitting. • S/PDIF, AES/EBU and ADAT™ signal distribution. MC-1 and MC-1.1 are multifunctional, high-performance digital audio format converters for S/PDIF and AES/EBU digital audio data. Using latest digital audio circuitries, both units process all formats with clock rates up to 192.0kHz! The format conversion process does not only the necessary electrical conversion but also a format conversion of the reference signals in compliance with the specifications which are standardized by the Audio Engineering Society (AES) and the International Electrotechnical Commision (IEC). Various additional operation modes like ADAT™ line extension through AES/EBU lines, SCMS processing or signal status detection enable the use of MC-1 and MC-1.1 in a wide range of applications. MC-1.1 especially offers double circuitries for bi-directional connections which allows to run two signal paths individually. In addition, this unit consists of two outputs for each digital audio format which enables to use MC-1.1 as an ADAT™ signal splitter and S/PDIF + AES/EBU distribution amplifier. APPLICATIONS: • Interconnection of consumer and professional digital audio devices. • Realtime bi-directional signal transfer and format conversion • between send/returns of digital mixing consoles and effect processors. • Uni- or bi-directional interconnection of computer-based sound cards • with professional digital audio equipment. • S/PDIF, AES3 and AES11 signal splitting and distribution. • Distance extension for ADAT™ and S/PDIF optical signals • through symmetrical AES/EBU lines for e.g. theater or broadcast installations. • Digital audio signal refreshing. • SCMS coding of digial audio productions to protect those against illegal copying. • S/PDIF optical/coaxial status analysing.
