Allowing Vista X and Vista V digital console users to transfer a very large number of audio channels, Studer has introduced D23m I/O system, which works with the company’s new Infinity Core and A-Link interface technology.
The D23m is fully compatible with D21m systems already in the field – all existing D21m I/O-cards can be used in the D23m frame. Plug-and-play features like automatic card detection are also available with D23m.
The card has a new and robust I/O frame for all future Studer mixing consoles using A-Link technology, wherever a high channel count is required. The ability to use D21m cards protects existing customer investments and offers a cost-effective solution. The use of different I/O modules – existing D21m cards or new I/O higher capacity and new format interfaces provides an I/O system tailor-made for customer needs.
The audio between the mixing console or router system and the D23m connects via the A-Link interface. The A-Link HD card hosts a powerful processor to operate all required patching and may be used as the sync master to the system, or may be slaved to a variety of external sync signals.
The D23m can host up to 12 I/O cards with a total of 1,536 inputs and 1,536 outputs, determined by the cards fitted. The system provides two A-Link ports and two hot-swappable power supplies (including secondary regulators) for redundant operation. Displays on the front panel indicate the status of the frame or installed cards.
The first Madi I/O card specifically designed for the new D23 frame is a dual-slot card with two redundant Madi interfaces, providing up to 128 channel inputs and 128 outputs on the fully-redundant interfaces. It works with Studer Vista X and Vista V digital consoles, and may also be used in the Vista 1 I/O card slot.
SFP modules are used for the front panel Madi interfaces, and these hot-pluggable devices are available in a variety of optical and electrical formats. Studer stageboxes have embedded control within the Madi stream, even if all 64 channels are used for audio. The new card may be connected to two Studer stageboxes, either D21m type or the Compact Stagebox. Full microphone control and remote frame status monitoring for both frames is provided on the console application.
Each of the two Madi interfaces provides dual outputs (with the same audio and control data). The Madi inputs will automatically switch in less than a millisecond to the reserve input if the data is corrupt or fails, thus providing full cable redundancy for typical OB operations.
Madi channel count to the D23m backplane may be set for both interfaces in eight channel steps individually from eight channels to 64 channels. Madi outputs may be set to 56-channel mode for compatibility with legacy equipment. Madi inputs may be in either 64- or 56-channel mode. Input sample rate converters may be enabled for use with non-synchronous sources.
The Madi interfaces will run at 44.1kHz, 48kHz, 88.1kHz and 96kHz in the D23m frame. The channel count is halved unless two pairs of cables are used.
