High power class-D 100V line slave amplifiers in a rack-mountable housing. Slave inputs accept standard line level audio from a mixer or RM series mixer amplifier. Slave outputs can be cascaded onto further RS slaves to build larger systems. All line level inputs are connectable via RCA sockets or hard-wired via removable screw terminals. A further removable screw terminal is provided for 100V input- which enables the RS series slave amplifier to extend an existing 100V installation by connecting directly to the 100V speaker feed- or indeed from a long distance 100V feed using standard double-insulated cable. A 24V terminal is provided for connection to a security or alert panel to mute the output if required during alarm triggering.
