The TX1 is a top specification FM broadcast transmitter that is ideally suited for micro power radio stations and cable modulators.
The Frequency is adjustable from 87.5 to 108 MHz from internal direct reading switches or from the front panel graphics display control system. Setting the frequency internally disables the menu system from changing the frequency ensuring no unauthorised frequency changes.
The TX1 LCD display on the front panel can indicate frequency and PLL locked status.
The Rear panel contains XLR balanced inputs with input level controls, BNC for multiplex output from the internal digital stereo generator, BNC for multiplex input to the exciter for loop through operation and external processor input.
The RF output is via an N type socket. Main input is via a fused swicthable IEC power connector.
The transmitter is fully configurable and the limiter and stereo encoder can be switched in and out of circuit. Jumpers available on board for pre emphasis, clipping, processing mode (clarity/loud), stereo/mono, and limiter on/off.
The 'virtual VFO' dual loop PLL system allows perfect audio flatness to below 10 Hz. AFC bounce and modulator overshoot are a thing of the past. You now can pass that low bass without distortion and overshoots and obtain that extra low frequency stereo separation.
Internal harmonic filtering keeps your RF signal clean and compliant to FCC/DTR standards.
The power supply section has a universal input voltage range from 85-260 volts AC. Ensuring computability of any mains system WORLD-WIDE.
The TX1 is an attractive all-in-one broadcast solution for small scale stations. Because the exciter, amplifier, power supply, stereo encoder and limiter are all in one case the price is less than half that of other comparable systems. Designed for the small scale broadcaster and at a small scale price.
