Extron Electronics, headquartered in Anaheim, CA, is a leading manufacturer of professional AA/system integration products including computer-video interfaces, switchers, matrix switchers, system controllers, distribution amplifiers, audio products, speakers, video scalers, scan converters, signal processing devices, Ethernet control interfaces, and high resolution cable.
The audio portion of the signal exhibited a rather low signal-to-noise ratio, and the "crashes" due to decoding errors caused overload in the distribution amplifier, in addition to being extremely objectionable.
Ross' new line of 3G DAs include single, dual, and quad channel distribution amplifiers that offer the flexibility of high density HD-BNC or standard BNC rear modules, non-inverting output support for DVB-ASI signals and fail over protection utilizing secondary inputs.
For more than 20 years, Extron Electronics has been a leading manufacturer of professional AN system products including computer-video interfaces, switchers, matrix switchers, distribution amplifiers, video scalers, speakers, signal processing devices, Ethernet control interfaces, and high resolution cables.

Booster amplifiers or postamplifiers increase the launched optical power at the transmitter side; preamplifiers improve the sensitivity of the optical receivers; and the in-line distribution amplifiers compensate for the fiber distribution loss.
Along with DEV's and fibre-optic RF signal transmission systems,switches, combiners and splitters the European company also supplies distribution amplifiers, distributing matrices, routing products, and multiplexers.
Matrix amplifiers, when compared with cascade-connected distribution amplifiers, provide about the same gain but have better input and output matching, a lower noise figure, and are more compact and less costly when fabricated in monolithic form.
