Product Description

The ZHC926I series host/backup switching integrated machine is a special equipment designed for the "1+1" master/backup switching system of broadcast and television transmitting stations, and is used to control the manual or automatic switching of the host/backup transmitter. Compared with the traditional host-backup switching equipment or system, the host/backup switching integrated machine has the advantages of a built-in coaxial switcher, no need transmitter communication protocol, it’s small size and convenient for installation.

In automatic switching mode, the all-in-one will automatically detect the working status of the host transmitter. When the output power of the host is lower than the preset switching threshold, the all-in-one will control the built-in coaxial switch and the power supply of the host and backup transmitters, and automatically switch to the backup The transmitter works to achieve uninterrupted broadcast.

In manual switching mode, you can manually operate through the panel switch to select the host or backup transmitter to complete the switching control of the coaxial switch and the power of the host and backup transmitters.

The ZHC926I series host and backup switching integrated machines are divided into two RF power levels: 300W and 1KW.
