1 PLUG Mains voltage plug
2 FUSE BLOCK Fuse block and line voltage selector.
Use a small screwdriver to change the
fuse or the line voltage. Rotate the
block and position it for the desired voltage.
3 INTERLOCK BNC connector. Connecting the central

stay there until the short is removed.
When used with an R.V.R. amplifier, this
connector should be connected to the
"REMOTE" output of the power amplifier.
