Adastra SA240 240W Lockable Wall-Mount PA Amplifier with Bluetooth & Mic
Adastra SA240 – A 240W Secure Wall-Mount PA Amplifier for Larger Public Spaces and Remote Installations.
High-Power Audio for Secure and Unattended Installations
The Adastra SA240 is a 240W wall-mount public address amplifier designed for environments that require reliable audio output in a tamper-proof format. Housed in a robust steel cabinet with a lockable front panel, the SA240 is well suited for larger-scale installations where access to AV equipment is restricted — such as sports pavilions, schools, scout huts, leisure centres, warehouses, council buildings, and remote outbuildings.
Designed for Public Address, Announcements, and Music Playback
Equipped with a built-in USB/SD media player, FM tuner and Bluetooth connectivity, the SA240 enables direct audio playback without needing external equipment. Whether you’re broadcasting background music in a community building or making announcements at a football ground or adventure park, this amplifier provides a complete and reliable solution in a single unit.
The included UHF wireless microphone is ideal for live voice reinforcement. Two additional XLR/jack mic inputs are available for wired microphones, with optional 48V phantom power for use with condenser mics. Each microphone input features a selectable priority function, allowing announcements to override background music for emergency messaging or routine communication.
More Power, Wider Coverage
Compared to the SA120, the SA240 delivers twice the power, making it better suited to larger buildings or wider speaker distribution. Its speaker outputs support both 100V line and 8-ohm speaker systems, offering flexibility for installers and making it easy to expand or retrofit existing audio infrastructure.
Built for Tough Environments
The secure, wall-mounted design of the SA240 makes it ideal for installation in semi-public or unattended areas where standard desktop amplifiers would be at risk of tampering. From school halls and outdoor facilities to changing rooms, village halls and industrial units, this amplifier is built to deliver dependable performance without constant supervision.

- 240W Power Output: Suitable for large spaces and multi-speaker 100V installations
- Lockable Steel Cabinet: Wall-mounted enclosure protects settings and prevents tampering
