Sony Broadcast and Professional UK has announced a significant enhancement to the triple award-winning DMX-R100 digital console, with the introduction of its DMBK-R109 MADI (Multichannel Audio Digital Interface) card. The interface expands to 108 the number of audio inputs that can be configured in a single DMX-R100 and supports the dual console cascade mode, providing an integrated 168-input, 112-channel, 48 fader digital mix system. Uniquely, the internal 32-bit fixed point Bus resolution is maintained between cascaded consoles, ensuring no compromise to the DMX-R100’s sound quality.

The powerful new DMBK-R109 utilizes the established AES 10 24-bit MADI I/O ‘bit-slip’ free standard and provides 48-channel digital I/O expansion compatible with other MADI devices such as the Sony PCM-3348HR DASH recorder. Compatibility with the expanding array of MADI stageboxes, audio routers and multi-track recorders also enables greatly enhanced functionality for multi-format film and surround mixing, music production, audio post, broadcast, radio production, live and theatre applications, via either low cost standard 75 Ohm BNC or long distance Optical connections.

The 48-channel MADI I/O expansion provides for 24-channel high-sampling-frequency operation at 88.2/96 kHz and the card takes up only one of the four available DMX-R100 expansion slots; the remainder remaining free for the full range of pre-existing expansion I/O options to cater for a considerable number of operational configurations. Recently released Version 2.1 software, includes new GUI touch-screen pages that accommodate all DMBK-R109 input and output routing options, whereby MADI signal can be freely routed to the DMX-R100’s internal input and output processing channels.

In the dual console cascade mode, with one DMBK-R109 fitted per console, a total of 112 audio signals can be mixed to 18 buses (56 signals mixing to eight buses at 88.2/96kHz). The cascade system is based on a Master and Sub console configuration, providing 48 channel faders and solo logic linked via use of on-board DMX-R100 PC serial ports. Multiple operating modes are supported as each of PGM, MTR, Aux and AFL/PFL buses and can be individually selected to cascade with or without automatic time alignment. The normal range of I/O expansion remains available, with the remaining three expansion slots per console providing a possible 168 inputs for the cascade system.
