XA200 Owner’s Manual

ing without excessive force is plenty. Cleaning contact surfaces with one of the commercially available electronic contact cleaners should be part of your annual system maintenance.

The XA200 has a single large power transformer, under actual condi- tions in the amplifier, it supplies but a fraction of its rated power. This very conservative rating contributes to exceptional voltage regulation figures and low noise figures at the loudspeaker.

The XA200 has a significant number of power supply filter capacitors. These caps are used to create the unregulated output stage rails at plus and minus 60 volts at 9 amps. RC filtering is used to passively remove ripple from the supply rails.

All the power transistors in the product are hyper-matched parts, with gate voltages matched to 0.5% and all devices taken from the same manufacturing lot codes (made on the same wafer).

So how long will this hardware last? It is our experience that, barring abuse or the odd failure of a component, the first things to go will be the power supply capacitors, and from experience, they will last 15 to 30 years. Fortunately they die gracefully and are easily replaced by a good technician. After that, the longevity will depend upon the number of operating thermal cycles, but we can say that we have had amplifiers operating in the field in excess of 20 years with no particu- lar mortality, and we don’t have good information beyond that. More to the point, you should not worry about it. This is a conservatively built industrial design, not a frail tube circuit run on the brink of cata- strophic failure. If it breaks, we will simply get it fixed, so sleep well.

XA200 specifications

The Pass Labs XA200 is a distinguished power amplifier that is acclaimed for its exceptional performance and remarkable build quality. Designed for audiophiles who demand the highest fidelity in their audio systems, the XA200 offers a unique blend of power, clarity, and musicality that sets it apart from the competition.

At the heart of the XA200 is a Class A topology, renowned for its ability to deliver pure and uncolored sound. This design ensures that the amplifier operates in its most linear region, providing a smooth and accurate response across the frequency spectrum. With an impressive output of 200 watts per channel into 8 ohms, and effectively doubling that power into 4 ohms, the XA200 is capable of driving even the most demanding loudspeakers with ease.

One of the standout features of the XA200 is its innovative use of the Pass Labs’ patented Feedforward error correction technology. This groundbreaking approach reduces distortion to extremely low levels, enabling the XA200 to produce a highly detailed and transparent soundstage. Additionally, the amplifier employs a combination of high-quality components, including custom-designed power supply transformers and large reservoir capacitors, to ensure stable operation under various load conditions.

The build quality of the XA200 is also noteworthy. Encased in a robust chassis with a striking aesthetic, this amplifier not only looks elegant but is designed to minimize vibration and resonance. The dual mono configuration of the XA200 ensures that each channel operates independently, further enhancing the overall sound quality and separation of instruments.

In terms of connectivity, the XA200 is equipped with balanced XLR inputs and single-ended RCA inputs, allowing for versatile integration into different audio setups. It also features a switching power supply that enhances its efficiency, ensuring that the amplifier remains cool even during extended listening sessions.

Overall, the Pass Labs XA200 is a testament to the brand’s commitment to excellence in high-end audio. Its combination of power, advanced technologies, and impeccable build quality makes it an ideal choice for audiophiles seeking a rich and immersive listening experience. Whether used in a dedicated home theater or a refined stereo system, the XA200 stands ready to reveal the true potential of any musical recording.
