The X Series Stealth PA-1 is a high performance balanced Class-D monoblock power amplifier. The PA-1 combines compact size, high efficiency, and excellent sound quality in a single convenient package.

The Stealth PA-1 is the ideal solution anywhere a small great sounding monoblock power amplifier is needed. Use one to power a center channel speaker, use a full set to power your entire home theater system, or use several of them to add extra channels to your current audio system.  Each PA-1 delivers 140 watts RMS into 8 Ohms, or 300 watts RMS into 4 Ohms. They are cool running and only require minimal ventilation. Because it’s so small, the PA-1 monoblock fits conveniently on any shelf, and rack mount kits are available to mount a single PA-1, or a pair of them side by side, in a single 1U rack space.

Not only does the Stealth PA-1 sound great, but it’s also simple to configure and use. The PA-1 runs on any line voltage between 100 VAC and 264 VAC, accepts a balanced input using either an XLR or balanced 1/4” connector, and can be configured to remain on continuously or to automatically switch itself on when it detects an incoming audio signal. Comprehensive protection circuitry protects the PA-1 from a variety of faults, without intruding on the quality of your music during normal operation, and automatically resets itself once the fault is removed.

    Protection

    • The Stealth PA-1 is protected against excessive temperature, short circuit conditions, excessive DC offset at the output, and various input signal fault conditions. The protection circuitry in the PA-1 is totally transparent in normal operation. If a fault is detected, the PA-1 will instantly mute its output, and continue to monitor the situation. As soon as the fault is removed, the PA-1 will automatically reset itself and return to normal operation.
