SoundTube Entertainment SA502 overview

  • 1Description

The SA502 50W Class D Mini Amplifier with Power Supply from SoundTube Entertainment offers a maximum gain of 34dB and dual concentric gain controls for independent channel control. It has three operating modes; stereo, dual mono, or bridged mono. In stereo, each input channel flows directly to its corresponding output channel. In dual mono, the left input is fed to both output channels. In bridged mono, the left input is fed to the bridged output.

The system includes a selectable 12 to 32V external trigger input or auto standby to conserve energy. It also features three user selectable input options, balanced stereo euroblock, unbalanced line level mini jack, and a stereo speaker level (amplified) euroblock input for applications with low wattage speaker outputs.

This compact yet powerful system is engineered for external amplification with SoundTube and other sound reproduction speakers. Additional applications include digital signage, education, point of purchase, museums, surgical centers, AV carts or any application where a small amplifier is needed to boost a limited source output (e.g. computers, A/V projectors, and more).

    SoundTube Entertainment SA502 reviews

    SA502 50W Class D Mini Amplifier with Power Supply is rated 4.0 out of 5 by 1.
    Rated 4 out of 5 by from Nice amp; kind of pricey I had to replace several amps for my SoundTube systems that were 10+ years old, so I ordered this model. It's well made, is easy to install, and performs as expected. My only complaint is that it seems kind of expensive for what it is.
