Description
In excellent condition, in original box and with accessories.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.Stealth Series: Designed For The Studio; But Great For Studio Or HomeAll of the components in our Emotiva X Series Stealth line were designed from the ground up with the demanding requirements of a professional recording studio in mind. All of our Stealth components incorporate the rugged construction, rock-solid engineering, and outstanding technical performance demanded by professionals. However, because we designed them to deliver true audiophile sound quality, they’re right at home in either a home studio or a high-end home theater or stereo audio system.Stealth QualityThe Stealth PA-1 monoblock power amp is built to last, with a heavy duty steel chassis, solid milled aluminum faceplate, and high-quality parts and construction throughout. The high performance ICEpower module, which incorporates virtually all of the active circuitry in the PA-1, including the amplifier section and integral SMPS power supply, has a proven track record of performance and reliability. We expect you to enjoy your PA-1 for a long time – and we back that up with a full five-year warranty.Designed and Assembled in the USAAll of our new PA-1 amplifiers are designed, assembled, and tested in the USA. Designing and assembling in the USA with globally sourced components gives us exceptional control over every facet of the design and production process, which helps us build the highest quality products for our customers while minimizing unnecessary complications and production delays. Each Emotiva amplifier is carefully designed with premium components to deliver a stunningly capable, reliable, and refined system. Circuit TopologyThe Emotiva Stealth PA-1 Class-D Monoblock Power Amplifier is a fully balanced high-performance Class D power amplifier featuring the ICEpower ASC300 amplifier module. The ICEpower ASC300 is self-contained, and includes an audiophile-grade Class D power amplifier, and an integral high-performance switch mode power supply.The Stealth PA-1 combines a very small form factor, high efficiency, minimal cooling requirements, and near-bulletproof protection, all in a convenient and economical package.Audio SpecificationsChannels: 1Output power: ?140 watts RMS into 8 Ohms at 1 kHz at 1% THD;135 watts RMS into 8 Ohms at 0.1% THD.?300 watts RMS into 4 Ohms at 1 kHz at 1% THD;270 watts RMS into 4 Ohms at 0.1% THD. ?450 watts RMS into 2.7 Ohms at 1 kHz at 1% THDInput impedance: 47k Ohms (balanced).Voltage gain: 28 dBFull power bandwidth: 20 Hz to 20 kHz.THD+N: 0.005% at 1 kHz at 1 watt into 4 Ohms.S/N ratio:?Referenced to 1 watt (A-weighted): 91 dB.?Referenced to full output (A-weighted): 112 dB.Frequency response: 20 Hz to 20 kHz +/- 1 dB (worst case; 4 Ohm load).Damping factor: >500Rated load: From 2.5 Ohms to 8 Ohms.Input And Output ConnectionsInput Connections: Balanced; (accepts XLR, balanced ¼”, unbalanced ¼”).Speaker Output Connections: Audiophile grade 5-way binding posts.Trigger:?The Stealth PA-1 can be configured to turn on when an audio signal is detected.Power RequirementsAnywhere between 100 VAC and 264 VAC @ 50 / 60 Hz (automatically detected).Standby power: Approximately 0.275 watts.Total power efficiency: Approximately 80%.Front Panel Controls and IndicatorsPower LED: Illuminates blue when the PA-1 is On.Rear Panel ControlsAC Power switch: Rocker switch (switches AC main power).Auto/On Switch: ?In the On position, AC power to the PA-1 is controlled by the AC Power switch.?In the Auto position, the PA-1 switches on automatically when audio is detected.ProtectionThe 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.MechanicalDimensions:?8-1/2” wide x 1-7/8” high x 9” deep (unboxed, including feet, not including connectors).?8-1/2” wide x 1-3/4” high x 9” deep (unboxed, without feet).Weight: 3 lbs (unboxed) 6 lbs (boxed)
