Description
- Three-program wired broadcasting transmitter "Yenisei UP-120" is designed to convert audio broadcasting signals into amplitude-modulated signals with the carrier frequency level, adjustable according to the envelope of the audio signal and transmit them over the wired broadcasting networks.
- The Yenisei UP-120 is designed as a monoblock, 2U in height, which allows you to place device in a standard 19" rack cabinet.
- The device is powered from a single-phase AC 220V, 50Hz, with mandatory grounding.
Application:
Wired broadcasting networks
