Input and Output Connections

The input and output connections to the system are made to the jacks mounted on the rear

panels of the CHV200B systems, the drivers for the CVH400B and high power systems, and

to the 500 Watt, 750 Watt and 1000 Watt amplifier trays. The CHV200B systems and the

drivers for the CVH400B and higher power systems accept an On Channel RF signal (BRD)

or a SMPTE-310 (BTD) input and output a digital RF ON Channel signal. Refer to Figure 3

and to Table 2 that follow for the locations and information on the jacks and connectors.
