The CT Series transmitters provide high quality Audio/Video Transmission by combining the NT transmitter and 1 W Power Amplifier in an enclosure with the convenience of front-panel control.
The new CT operates in L, S, or C-Bands and is available in either a 10 mW, 250 mW, or 1 W RF output power version. Broadcast quality video (NTSC or PAL) with one audio subcarrier makes this transmitter ideal for sports, airborne, and remote broadcasting. The CT Series is a fully synthesized multi-channel transmitter. Audio subcarrier input may be factory configured for either microphone or line level.
All transmitter functions are controlled by an advanced microprocessor with a user-friendly interface. A large LCD displays power on/off, and frequency of operation. The CT can also be controlled with the GMS Remote Control Unit or via an RS-232 interface. All operating parameters are stored in non-volatile memory so they are retained in the event of the loss of power.
