Stealth PA-1

 Introduction

Thank you for purchasing the new Emotiva Stealth PA-1 Class-D Monoblock Power Amplifier.  
The Stealth PA-1 is a high performance monoblock power amplifier featuring the highly acclaimed 

ICEpower 300ASC Class-D amplifier module. 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 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, and runs cool, so it only requires minimal 

ventilation. Because it’s so small, the PA-1 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. 

Happy listening!
The Emotiva Team
