OMNITRONIX OMNI-1000-SW

GENERAL DESCRIPTION

OMNI-1000-SW Solid State SW Broadcast Transmitter, 1,000 Watt

Tropical Band Short Wave

The only Solid State Tropical Band Transmitter in the Industry
Exceptional Efficiency
High Reliability
One Year Limited Warranty

The OMNI-1000-SW is the 1,000 watt member of the Omnitronix series of competitively priced, highly efficient AM Short Wave Transmitters. This 100% solid state transmitter uses proven pulse duration modulation (PDM) technology to provide highly efficient broadcast operation. Enhanced reliability has been built into the OMNI-1000-SW through the use of redundant modulator and power amplifier circuitry, extensive antenna and power-mains transient protection and the use of stainless steel hardware and Teflon insulated wire throughout the transmitter chassis. Troubleshooting has been made easy through the use of meters and numerous LED status and alarm indicators. The advanced modular design allows front-panel access to all plug-in power amplifier and control modules. This, in addition to true "hot-swap" capability, provides for quick and easy maintenance which virtually eliminates off-the-air situations. The superior reliability, rugged design, highly efficient AC to RF conversion, and ease of maintenance makes the OMNI-1000-SW the most cost effective solid state AM short wave transmitter available. The OMNI-1000-SW solid state transmitter meets the specifications of various international broadcasting authorities.
