Signal Distribution Tech Showcase

The commercial AV systems that we design and install on a daily basis vary quite dramatically in size, scope, and function. No matter the system, all share one fundamental requirement: We must be able to route the signal from its source to its destination.
Today, manufacturers have provided us with more options than we have ever had to accomplish this task. We have the capability to route almost any signal over almost any method imaginable. Coax, twisted pair, fiber, and even wireless are viable methods of signal distribution that we can incorporate into our systems. Take a look at the latest signal distribution products from our industry’s leading manufacturers:
Atlona’s new AT-AiR3 wireless adapter allows any Windows or Mac computer to be displayed wirelessly onto a monitor, projector, or TV through either VGA or HDMI. The AT-AiR3 uses a USB dongle for connection to the source computer, and a receiver located at the display for connection of VGA, HDMI, and analog audio. The wireless connectivity eliminates the presenter from being tethered to a cable at a fixed location. It allows the source computer to be located or moved up to 30ft. away from the receiver. The unit supports audio through the HDMI connection as well as the analog audio output if an analog video signal is present on the VGA output. It is capable of mirroring, or extending the display, and supports resolutions up to 1080p.
The Hono CobraNet series of networked audio encoders and decoders from AudioScience offers a solution for any CobraNet audio need. The Hono CobraNet line is comprised of the Mini, Fixed, and Custom series. The devices are available in configurations starting at two inputs and outputs in the Mini series, all the way up to 16 inputs and output in the Fixed series. The Custom series allows up to 16 inputs and outputs per frame on modular cards allowing the configuration to be built in any needed combination. Input options for the Hono CobraNet line include balanced mic or line analog inputs and AES / EBU digital inputs. Outputs are either balanced analog line level, AES / EBU digital. The entire series is compatible with all other AudioScience CobraNet devices, as well as other third party CobraNet equipment.
Black Box offers a full lineup of signal distribution products. Two of its newest are from its ServSwitch family. TheServSwitch Wizard DVI-D Plus USB Extender transmits single-link DVI-D video signal and USB over a single Category cable. Resolutions up to 165 megapixels per second (the fastest rate available for single-link signals) can be achieved with no compression or conversion. 1080p video can be transmitted up to 165ft. without any loss. The ServSwitch Wizard SRX DVI-D Plus USB Extender also contains a built-in four-port USB hub at the receiver unit. This allows connection of up to four USB devices through the extender with only a single USB connection at the transmitter.
The ServSwitch Wizard USB KVM Extender with Audio allows VGA, audio, USB, and keyboard and mouse to be extended up to 1000ft. over a single category cable. Resolutions up to 1600x1280 are supported for the VGA connection. Analog audio is supported through standard 1/8in. input and output jacks. Like its DVI sibling, the ServSwitch Wizard USB KVM Extender with Audio also contains a built-in four-port USB hub on the receiver.
DVIGear recently introducedits new line of HDMI and DVI extenders. The new lineup consists of transmitters and receivers which require two Cat-6A /Cat-7 cables for transmission between the units. The basic units support HDCP on both the DVI and HDMI versions, and include automatic cable equalization. Expanded units are available with RS-232 pass-through, and pixel accurate reclocking, as well as manual cable equalization for fine-tuning the performance of the transmitters. The transmitter and receivers may be used as a standalone extension for a signal or may be integrated and powered with DVIGear’s MXP series routers. Rackmount kits are available.
Extron Electronics’s new line of Digital Twisted Pair extenders provides long-distance signal transmission for most applications. The DTP HDMI 301 digital twisted-pair extender set transmits HDMI, RS-232, and IR signals over a single Cat-5-type cable. The set can send 1080p/60 deep color or 1920x1200 signals up to 100 meters (330ft.). A second twisted-pair cable connection may also be used to transmit an analog stereo audio signal. The signal maintains full HDCP and DDC EDID communication between source and display to ensure a consistent high quality image. The extender set may be powered from either end—a feature very useful in keeping the clutter of external power supply units to a minimum. Like its cousin above, the new DTP DVI 301 digital twisted-pair extender set also transmits high-resolution 1080p/60 deep color and 1920x1200 signals up to 100 meters on a single twisted-pair cable. It features the same signal support and specifications as the DTP HDMI 301, in addition to a buffered loop-through output to support a local DVI-D monitor connection. The DTP HDMI 301 and DTP DVI 301 transmitters and receivers may be mixed and matched as needed to comply with the installation at hand.
FSR’s most recent addition to its signal distribution lineup is the TwisterPro series. The TwisterPro UTP transmitters and receivers provide video, stereo audio, RS-232, and IR signal extension up to 1000ft. over Cat-5, Cat-5e, and Cat-6 cable. The units provide error-free transmission, which is virtually immune to electrical noise interference. Both transmitters and receiver units are available in wall-plate-style units, as well as “brick” housing versions capable of being surface mounted or attached to a rackmount kit. Receivers are also available with skew adjustment to compensate for varying cable twist rates. A TwisterPro Hub unit is also available to allow cascading of units up to a maximum of 512 outputs.
