Description
The SoundTube SA502 Mini Amplifier is a 50-watt-per-channel (4Ω) amplifier with flexible input options including balanced stereo euroblock, unbalanced line-level mini jack, and a stereo speaker-level (amplified) euroblock input for applications with low-wattage speaker outputs, making it suitable for integration with central sound controllers.
The SA502 offers three operating modes: stereo, dual mono, or bridged mono. In stereo mode, each input channel feeds its corresponding output channel. In dual mono, the left input is routed to both output channels, while in bridged mono the left input feeds the bridged output. The amplifier includes a selectable 12–32 V external trigger input or auto-standby function to conserve energy.
Compact, powerful, and cost-effective, the SA502 is engineered for external amplification with SoundTube and other high-fidelity loudspeakers. Additional applications include digital signage, education, point-of-purchase systems, museums, surgical centres, AV carts, and any environment where a small amplifier is required to boost a limited source output.
