Adastra SA Series Secure Wall Amplifier 100V with UHF Mic + Media Player

Public address mixer-amplifier built into a surface-mount secure box. A powerful output can drive either 100V line or low impedance speakers from binding post terminals inside the cabinet.

The system includes a handheld UHF microphone with an inbuilt receiver and 2 switchable wired mic/line inputs are provided on combo XLR/jack sockets. Each mic input has switchable +48V phantom power and priority override, which mutes the Aux inputs during voice operation.

An internal media player enables playback of audio tracks from USB/SD player, FM tuner or Bluetooth pairing. Alternatively, line inputs can be connected to the Aux 1 RCA sockets or separate Aux 2 RCA/3.5mm jack sockets.

The combination of flexible input section and a high efficiency amplifier in a strong, lockable cabinet provides a complete solution for buildings where security and ease of use is essential.
