The Cloud MA40F is a compact, 40 W mono mixer-amplifier designed for “install‑and‑forget” audio applications. Its small footprint allows mounting in ceiling or wall cavities, making it ideal for spaces like galleries, museums, digital signage installations, and tour-guide systems.
It supports two line inputs, a facility port (for modules like LM-2 or BT-1F), and a paging mic input (SW/VOX) with priority control. The integrated 70/100 V line input offers even more flexibility for distributed audio systems. Power is supplied via 12–24 V DC, perfect for mobile or low-voltage environments, while auto power-down (APD) helps save energy. Additionally, the amplifier includes a music mute input, ideal for fire-alarm or emergency paging integration.
