Signal success with connectivity solutions.
The AV community is full of excitement. Let’s face itwe make our living every day working with the latest technology available. By the rest of the world’s standards, we play with toys all day long.
Every year we look forward to the new box that gives us an extra input, output, watt, or lumen. We are blown away by the display that boasts a 3in. larger diagonal display than its competitor. The advancements brought about by new technology never fail to wow and amaze us.
The wow and amazement typically stops at the loudspeaker, display, or equipment rack. Rarely do we take the time to consider all of the connections between the various boxes of flashing lights.
Cable and connectors may not seem like the most exciting product we deal with, but as technology has advanced, and we have continually pushed the envelope of higher quality sounds and images, they have become more critical to our success. We no longer have the luxury of using any old piece of copper to pass the signal. We now have to take seriously the role that quality cables and connectors play in our toy box.
To meet the challenges and demands of advancing technology, manufacturers have developed high-quality cable and connector solutions that help us to achieve the top performance of every system we touch. It is in our best interest, and quite frankly our duty as AV professionals, to study and embrace these new connectivity solutions with just as much excitement as we would any new product.
Atlona Technologies has released a new line of HDMI and HDMI-to-DVI cables with swivel connectors. The connectors of the cables swivel a full 180 degrees to allow the connection to be made to the equipment without bending the actual cable. The cables are constructed of premium materials and are HDMI1.3b-certified. They support 36-bit deep color, resolutions up to 1080p or 1920x1200, and feature triple shielding for maximum rejection of RFI and EMI. The HDMI and HDMI-to-DVI swivel connector cables are available in 3ft., 10ft., and 16ft. lengths.
The company’s new line of Mini DisplayPort fiber-optic cables now provides a way to extend displays up to 330ft. from a PC or Mac computer. The cables take power from the Mini DisplayPort output of the computer so no additional power supply is required. Also included are adapters to convert the cable to standard DisplayPort male connectors. They support a resolution of up to 2560x1600, 16-bit color, and speeds up to 10.8Gbps. They are DPCP- and HDCP-compliant and provide full extended display identification data (EDID) pass-through between source and display. The Mini DisplayPort fiber-optic cables are available in 33ft., 66ft., 100ft., 130ft., and 330ft. lengths.
Audio Accessories’ line of digital audio to BNC patchbays offers advantages over traditional audio patchbays. The patchbays themselves use standard 110&OMEGA; mini, TT, or Bantam audio patch cords on the front. The rear of the patchbays feature standard BNC connectors. Each jack has a built-in balun to match the unbalanced 75&OMEGA; coaxial cable connection to the balanced 110&OMEGA; jack. This conversion meets the AES3 standard, allows longer cable runs with less distortion, offers the capability of higher sampling frequencies, and provides greater noise immunity. Easy installation and high reliability are provided by the standard BNC connectors and 75&OMEGA; coaxial cable used for connection between patchbays.
