The GTX Series transmits true-digital, no-continuous-carrier UWB pulses. The system doesn’t utilize traditional continuous-carrier waves, so there’s no chance of constructive or destructive interference, and no frequency coordination is required.
The system is controlled via a custom TDMA scheme and patented clock sync and cable compensation technology through multiple GTX32 transceivers. The GTX32 transceivers coordinate system timing, give permission to GTX24 transmitters to transmit, and perform several layers of data validation and error correction. Each GTX32 transceiver can coordinate, receive and process signals from up to 24 simultaneous GTX24 transmitters. Signal reception is not dependent on phase or wave shape. The system only needs to see a “pulse” at the appropriate time in the TDMA scheme for the signal to be linked and captured.
Each pulse is extremely short, lasting only 2.5 ns. This is an important point because it means that the system is almost always “off.” The system is on (i.e., transmitting a signal) only 1.2% of the time, and off the remaining 98.8% of the time. As a result of this very short duty cycle, the GTX24 body-pack transmitter stays cool, while its signal remains effectively invisible to surrounding equipment. The timed sequence of short-duration pulses also makes the system inherently secure, since a receiver must know exactly when, where and how to “look” for the pulse in order to decode it.
Unlike traditional RF systems, the GTX Series sets up easily, doesn’t hog rack space, and doesn’t require expensive cables or extra equipment in order to operate.
The GTX Series eliminates the need for extra support equipment. The use of custom cavity filters and additional filtered/tuned antennas has become standard practice for high-profile professional events and installations. Traditional event and location set-up also depends on deploying custom distribution amplifiers and combiners which are expensive and difficult to change if / when additional channels are needed. These “extras” are expensive to purchase (or lease), expensive and time-consuming to set up, and require specialized experts and significant time to deploy. The GTX Series requires none of these extras in order to operate, saving you considerable time and money, and allowing for future flexibility.
Takes up only 3U rack space for 24 channels of on-air audio, plus another 24 channels of talkback audio and 8 “group assignment channels.” Traditional analog and digital wireless systems generally require 1U of rack space for every one or two audio channels. In a control room where cabling, space, power and heat are all important considerations, the GTX Series represents a dramatic improvement over any system on the market.
Use up to 1,000 feet of standard Cat 5 cable. The GTX32 transceivers connect to the GTX3224 control unit via standard shielded Cat 5 cable. This cable is readily available, and indeed is already used throughout most facilities, broadcast or not.
The GTX Series system can utilize runs of up to 1,000 feet with Cat 5 cable, compared to the 300 or 500 feet that is typical with the cable currently used in most systems. Plus, traditional cable is expensive and much more difficult to use than Cat 5.
The GTX Series gives you the ability to set up and confirm operation of 32 transceivers and 24 transmitters in a few hours. The importance of this cannot be overstated. With most wireless systems currently on the market, designing for their use in a broadcast studio starts months – or even a year – in advance. Careful consideration must be given to frequency coordination, use of accessory antennas and distribution boxes, connection of custom or expensive filters (and the very expensive cables used for connection), building and running of expensive cables, allocation of space and power to large racks of receivers, antenna distribution gear, and breakouts for digital output devices (such as MADI or Dante™) if interfacing with a network/protocol system. Such a system takes months to install, debug and qualify. With the GTX Series, it is possible to completely place, connect, debug and perform 100% coverage “commissioning” in a few hours. That means 24 channels of high-fidelity, reliable wireless in hours rather than months.
The game-changing technology of the GTX Series provides cost savings now and in the future. Based purely on the purchase price of the components, the cost per channel is comparable to other professional wireless systems currently on the market. But since the system sets up so quickly, utilizes low-cost Cat 5 cable, and doesn’t require any frequency coordination plans, the GTX Series actually provides considerable cost savings. Plus, since it operates in a portion of the spectrum unaffected by shifting regulations, the GTX is a wise investment that will save you the cost of purchasing additional equipment every time the spectrum requirements change.
The GTX Series components are sold separately to provide systems that are tailored to your specific needs. The GTX3224 control unit has inputs for 32 GTX32 transceivers; giving you the power and flexibility to cover even the most complex spaces and workflows.
