The operator attempted to resolve the problem by installation of booster amplifiers on the low-level feeds, but found the average levels to vary over 20 dB, thus the --40 dB feed, after boosting, would periodically rise to --20 dB, thus causing clipping and overload of the distribution amplifiers feeding the modulator.
The third product is a new dual-channel 12G reclocking distribution amplifier (model: DVD 1423), which accepts a single input and offers three outputs (per channel).
Other equipment installed in SABC's mobile MCR includes a Riedel communications system, Tektronix waveform monitoring and an Axon Synapse modular HD monitoring distribution amplifier with embedded 3G/HD/SDI.
Meanwhile, Sonifex, a manufacturer of broadcast audio equipment for the radio, TV, security and telecommunication industries, recently introduced three audio distribution products: The RB-DA6R six-way stereo distribution amplifier; the RB-DA6RG stereo distribution amplifier; and the RB-DDA22 digital audio distribution amplifier.
The 1-in 2-out VGA distribution amplifier is integrated into a 12" molded cable, which accepts standard VGA-UXGA input through a 15-pin connector.
The model 80163 duplexer/combiner/receive distribution amplifier (RXDA) is designed for 900 MHz wireless data two- or four-channel operation.
As momentum builds for Ultra HD 4K television, the company has introduced new additions to its Synapse signal processing line including a 4K up, a down converter, a distribution amplifier and two production 'Tool Boxes'.
The unit features frequency stabilities on the order of [10.sup.-13]/day and [10.sup.-11]/year; 1, 5 and 10 MHz sine wave and 1 Hz and 1, 5 and 10 MHz square wave outputs; a 1 pps synchronized output; and a built-in six-output distribution amplifier. In addition, a Global Positioning System (GPS) synchronizing input enables a cesium beam performance upgrade using a GPS time and frequency standard.
The solutions include a Sonifex audio mixer S1, a CD recorder/player, a Protonet ISDN and IP audio codec, four wireless microphone and headphone systems, Sonifex dual telephone hybrids, a Denon tuner, the Sonifex headphone distribution amplifier, monitor speakers, and shelf drawers for mounting programme playback laptops.
