Adastra SA120 120W Lockable Wall-Mount PA Amplifier with Bluetooth & Mic
DETAILS
Adastra SA120 – A 120W Secure Wall-Mount Amplifier Built for Public Spaces, Outbuildings, and Remote PA Systems.
Designed for Secure, Unattended Audio Installations
The Adastra SA120 is a wall-mounted 120W public address amplifier built specifically for environments that demand secure, tamper-resistant operation. Housed in a steel cabinet with a lockable front panel, it’s ideal for permanent installation in public buildings, scout huts, outbuildings, village halls, sports pavilions, and remote structures such as storage units, paintball arenas, or water sports centres — anywhere where a reliable PA or background music system is needed but may not be regularly attended.
A Simple All-in-One Solution for PA, Music & Announcements
The SA120 combines multiple audio functions in a compact wall-mount design. It includes a built-in media player for USB/SD playback, FM radio, and Bluetooth streaming, removing the need for separate source equipment. It’s perfect for playing background music in community buildings or triggering pre-recorded safety messages in remote facilities.
With a UHF wireless handheld microphone included and two additional mic inputs with phantom power, it’s also fully equipped for live announcements. Mic priority settings ensure spoken messages clearly override any ongoing music or audio, making the SA120 suitable for both general public address and emergency situations.
Flexible Inputs, Reliable Output
In addition to its onboard media player and wireless microphone, the SA120 includes standard Aux inputs via RCA and 3.5mm jack for connecting laptops, CD players or other external devices. It delivers 120W of power and supports both 100V line speaker systems and 8-ohm speakers, allowing integration into existing installs or new systems with ease.
Ideal for Use in Public and Semi-Public Environments
What makes the SA120 stand out is its suitability for installations where access to the amplifier needs to be restricted. Schools, sports grounds, community centres, council buildings, warehouses, and rural outbuildings often require sound reinforcement, but without the risk of unauthorised tampering. The SA120 addresses that directly — offering everything you need in one self-contained, secure unit.
