Part of the TICA® series, AMP405 combines compact size, passive cooling, and high efficiency – ideal for a wide range of audio installation applications.

The highly efficient four-channel 50 W Class-D amplifier can drive low-impedance loudspeakers in different zones.

Its tiny 142 × 44 × 222 form factor and included mounting plates allow it to be installed discreetly almost anywhere: behind screens, under tables, or even in air-handling spaces and above plenum ceilings. Alternatively, it fits into a 1/3 19? rack. Use the optional rack tray to slot up to three TICA® series products alongside each other and build a system to your exact requirements, using minimal rack space.

Terminal strip connections on the balanced line input and speaker output make wiring easy.

With remote-control connectivity to put the power amplifier into standby mode at any time, even when it’s hidden. Optional auto-standby saves power when no audio is running.

The perfect solution for professional installers and users looking for a compact, highly efficient, and easy-to-integrate solution.
