The XPA HC-1 is protected against excessive operating temperature, shorted speaker connections, ground faults, and other common fault conditions.Ĩ-3/8” wide x 7-5/8” high x 19” deep (unboxed including feet and connectors).Ģ4-3/4” wide x 12” high x 14-1/2” deep (boxed). Circuit Breaker: press button to reset circuit breaker.Status LED switch: disables front panel Status LED and dims Standby button halo.AC Power switch: rocker switch (switches AC main power).An AES3 signal can carry two channels of pulse-code-modulated digital audio over several transmission media including balanced lines, unbalanced lines, and optical fiber. Standby: push button (halo ring changes color to indicate Standby or On). AES3 is a standard for the exchange of digital audio signals between professional audio devices. Speaker Output Connections: Audiophile grade, gold plated, 5-way binding posts.īetween 100 VAC and 250 VAC 50 / 60 Hz (automatically detected).Input Connections: Unbalanced (RCA) balanced (XLR) independently selectable.Input Sensitivity (for rated power 8 Ohm load): 1.7 V.Minimum Recommended Load Impedance: 4 Ohms. > 95 dB ref 1 watt unbalanced input (A-weighted). The XPA HC-1 features a single High-Powered Single Channel Amplifier Module.ģ00 watts RMS 20 Hz – 20 kHz THD 120 dB ref FTC rated power unbalanced input (A-weighted).The XPA HC-1 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).The XPA HC-1 is a monoblock audio power amplifier, with a fully discrete, dualĭifferential, high current, short signal path Class A/B amplifier section, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.Each individual XPA amplifier is modular, and can be customized to provide exactly the power and number of channels you need today, and expanded later if your needs change and multiple matching chassis enables you to add even more channels, or more power, for a nearly endless variety of options. Every amplifier in the new Third Generation XPA series was carefully designed to deliver superb technical performance, unsurpassed sound quality, and an exceptionally accurate and dynamic rendition of all types of music, thus ensuring that your entire system will sound its absolute best. While this may seem trivial, a really good power amp is essential to having a great audio system, because any flaws in the performance of your power amp are going to limit the performance of your entire system. The power amplifier performs the simple but critical job of boosting the output signals from each channel of your stereo preamp or surround sound processor to the level necessary to drive your loudspeakers.
