Adastra 120W 1U 19 Rack Mountable 100V Line Slave Amplifier
120W 1U rack-mountable 100V line slave amplifier. Features Class-D tech, switchable 100V/2 Ohms output & 24V mute for alarm panels.
The Adastra 120W 1U 19 Rack Mountable 100V Line Slave Amplifier is a highly efficient and lightweight Class-D amplifier designed to power medium to large installations from a mixer output or to expand existing systems. Housed in a standard 1U rack-mountable enclosure, it offers exceptional versatility and reliable performance for professional audio setups.
Slave inputs readily accept standard line-level audio from a mixer or RM series mixer amplifier, whilst slave outputs can be cascaded onto further RS slaves to build larger, more comprehensive systems. All line-level inputs are connectable via RCA sockets or hard-wired using removable screw terminals (Euroblock), providing flexible connectivity options to suit various installation requirements.
A key feature of this amplifier is the removable screw terminal provided for 100V input, enabling it to extend an existing 100V installation by connecting directly to the 100V speaker feed, or from a long-distance 100V feed using standard double-insulated cable. Additionally, a 24V terminal is provided for connection to a security or alert panel, automatically muting the output during alarm triggering for enhanced safety compliance.
Speaker outputs are switchable between 100V or low impedance, which is stable down to 2 Ohms, allowing multiple low impedance speakers to be connected if preferred. The unit features a master volume control and includes a UK mains plug (Type G) for straightforward installation.
