TEKO Broadcast AXON 500W FM Transmitter

TEKO Broadcast AXON 500W is a compact 2U FM transmitter with adjustable 500W output, 87.5–108 MHz coverage and mono/MPX or stereo configurations.

TEKO Broadcast AXON 500W FM Transmitter combines an FM exciter and solid-state LDMOS amplifier in a compact 2U chassis. Adjustable output from zero to 500 W supports standalone broadcasting or use as a driver in a larger transmission system. Standard frequency coverage is 87.5–108 MHz, programmable in 10 kHz steps, with alternative regional bands available upon request.

RF Output and Operational Protection

The TEKO Broadcast AXON 500W transmitter provides a 50-ohm N-type RF output and a separate BNC monitoring connection. Front-panel indication of forward power, reflected power and modulation supports routine checks. Automatic power foldback responds to excessive antenna mismatch, with the published specification identifying 1.5:1 as the maximum normal VSWR. Microprocessor-controlled frequency synthesis provides stated stability better than ±150 Hz between −10 and +50°C.

Audio and Modulation Configurations

TEKO Broadcast AXON 500W is available with mono/MPX or stereo input configurations. The AXON family specification includes XLR analogue audio connections and a BNC composite input for externally generated MPX signals. Selectable flat, 50 µs and 75 µs pre-emphasis supports different processing arrangements. Stereo encoding, AES/EBU digital input and Audio over IP are configuration-dependent facilities that should be confirmed against the supplied unit.

Station Integration and Remote Options

An LCD display, direct-access keys and status LEDs provide local control. Seven stored setups support multi-configuration applications, including integration into suitable N+1 systems. Available options include dynamic RDS with TMC, web TCP/IP and SNMP connectivity, and a parallel remote-control interface. Aluminium construction, a serviceable front air filter and ducted cooling support equipment-room installation. Specify the required audio and control options together rather than assuming every advertised capability is included.
