CANFORD MUSA HD 3Gb/s 1080p VIDEO PATCH PANELS, TWO WAY (either/or) OR MONITORING
3Gb/s 1080p HDTV, 1.5Gb/s 1080i HDTV, SDTV, Analogue and Unbalanced 75ohm AES Audio
These 2U panels offer three rows of up to 24 MUSA HD 3Gb/s sockets. Adjacent rows are at 1U U-link pitch suitable for use with Canford 4401 U-Links.
The connectors are a completely new version of the MUSA, re-designed for 3G and 1.5G high definition, standard definition and analogue video applications. The performance exceeds the requirements of SMPTE292M and SMPTE424M making them suitable for composite and component video, 270 Mb/s SDI and uncompressed 1080i or 1080p HD-SDI video up to 3Gb/s. Also suitable for unbalanced 75ohm AES digital audio. The connectors are straight-through, non-normalled, and require U-links or patchcords. Rear connection is via 75ohm BNC sockets. Connector configuration is 3-rows in 2U.
There are a variety of applications for these unique three row panels, here are a few suggestions: Patching a source on the centre row, to one of two possible destinations, top or bottom, for instance from a vision mixer to a VTR or hard-drive storage, or in a transmission line where one destination is the primary, the other being the backup. Inversely, one of two source signals, connected to the top and bottom row can be patched to the centre destination row. Alternatively a source signal may be split via a router or DA and fed to both top and bottom row enabling patching of the programme (top) signal to the centre row destination, while allowing simultaneous occasional monitoring via a patchcord inserted in the lower row.
The simplicity of the one-piece contacts in both panel connectors and U-links, and the non-normalled, U-link concept, means there are no complex moving parts or switch contacts, offering excellent reliability even when subjected to vibration in use or in transit. The body parts are nickel-plated and centre contacts are gold plated giving a smooth mating action and overcoming the 'sticktion' and tarnishing of the now obsolete silver MUSA. Solid interface insulators prevent dust ingress meaning dust caps on unmated ports are unnecessary.
Manufactured from a rigid aluminium extrusion, panels are fitted with a lacing-bar for each connector row; additional mounting holes allow the bars to be repositioned where alternative cable-routing is preferred. Three designation-strip holders with snap-on covers are fitted (two above and one below the connector rows) and permit paper strips to be inserted before or after installation; 7.5mm of printable height is available. Templates for printing designation strip labels, available as a DWG file for AutoCAD and compatible applications, can be downloaded from the appropriate product page on the Canford website.
Depth behind panel, including lacing-bar, 180mm.
Available finished in Dawn Grey (BS4800-10A03) or Black as standard, other colours are available to special order but may be subject to a minimum order quantity.
Optional accessories: 3-row 1U panels require Canford 4401 1U size U-links, see Canford MUSA U-Links - 3G HD-SDI. For flexible patch cords, see Canford MUSA HD 3Gb/s 1080p Patchcords. Spare 432mm designation-strip paper (not suitable for printers) and covers, see Designation strips - snap on.
Recess rack-mounting brackets are available to recess panels within the rack, see Canford Rackbracket - Recess mounting brackets.
Technical Specification: SMPTE 292M & 424M Standards
SMPTE 292M is a standard published by SMPTE which allows for bit-rates of 1.485 Gb/s, and 1.485/1.001 Gb/s. These bit-rates are sufficient for to transport uncompressed High Definition video. This standard is usually referred to as HD-SDI and is one of a number of standards that define a Serial Digital Interface based on a coaxial cable, intended to be used for the transport of uncompressed digital video and audio in a television studio environment. SMPTE 424M develops SMPTE292M allowing for bit-rates of 2.970 Gb/s and 2.970/1.001 Gb/s over a coaxial cable or connector panel. These bit-rates are sufficient for uncompressed 1080p video at 50 or 60 frames per second often referred to as 3G HDTV.
The stipulated interface condition (cable & connector) are:
SMPTE 292M - insertion loss 20dB or less at 750MHz - return loss 15dB or less at 1.5GHz.
SMPTE 424M - insertion loss 20dB or less at 1.5GHz - return loss 15dB or less at 1.5GHz and 10dB or less at 3.0GHz.
