100V slave amplifiers built into a half width 1U housing. In addition to RCA line input and output, the US amplifiers have a 100V input on removable screw terminals, which enables the amplifier to be connected in parallel with existing 100V speakers to extend the system. Mono output to either 100V line or an 8 ohm speaker load is connected via a separate removable screw terminal connector on the rear panel. Supplied with rack-mounting hardware which can be configured to mount a single unit against a wall or under a worktop. Designed as a versatile solution for small to medium PA installations.
