Cabling
The PA 300 is specifi cally designed for long cable run
applications. For best results, install the amplifi er close to the
signal source and drive a long cable to the display.
The input of the PA 300 is on BNC connectors. If the source
output uses a 15-pin HD connector, use an Extron SYM BNCM
cable (Extron part #26-533-xx) to make the connection. See the
illustration below.
