Adastra SA240 Secure Lockable Wall Amplifier 100V with UHF Mic & DAB+ Media Player

Description

Public address mixer-amplifier built into a surface-mount secure box. A powerful 240W 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 two 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, DAB+/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. For emergency control, there are 24V terminals on the bottom for patching into an alarm panel to mute all except the Mic 1 input. 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.
