XA200.5 Owner’s Manual

X amplifiers run at about the same power as their output rating, and XA amplifier run more than twice that. The heat sinks on the side of the amplifier run hot to the touch – about 25 to 30 degrees C. above ambient, so you can expect 50 to 55 degrees C. temperatures on the heat sinks. It is very important to the long life of the amplifier that they get good ventilation.

You can put this amplifier anywhere you want, but it must have good ventilation. Do not place it in enclosed cabinets or small closets without means for air to circulate freely. Stacking these power amplifiers directly upon each other is not recommended for the same reason. You should have a minimum of about 6 inches clearance to the top and sides for adequate air circulation.

When not actually intending to play music the amplifier should be left in standby mode, where it draws only a few watts of bias on the output stage. If you wish to reduce the power draw to 0, you can shut the amplifier off via the rear panel switch, however we recommend that for minimum noise this switch should be toggled in stand-by mode.

We have provided a standard IEC power cord that fits into the standard 15 amp IEC receptacle at the rear of the amplifier chassis.

With the exception of the largest of the X and XA series, there is no difficulty running two amplifiers on a single 15-amp circuit. Given the high current draw, we generally do not recommend active line conditioners, although they are unlikely to damage the amplifier.

This amplifier is equipped for operation with an earth ground provided by the users AC outlet. Never defeat this ground connection. The signal ground of this amplifier is connected to earth through a power thermistor, which provides a safety ground but provides isolation from system ground loops.

For maximum safety we suggest that the power cord should be the last cable installed on your power-amplifier. You may, if you wish, substitute a 15-amp aftermarket power cord for the one we have supplied. Only use power cords, which meet all local safety standards and carry acceptance marks from the local regulatory authority. The power cord should be attached to the amplifier prior to plugging into house power. Place the rear mounted switch in the off (down) position before plugging in this amplifier.

XA200.5 specifications

The Pass Labs XA200.5 is a distinguished power amplifier that epitomizes high-end audio engineering, renowned for its exceptional sound quality and performance. Designed to cater to audiophiles and serious music lovers, the XA200.5 combines innovative technologies with elegant craftsmanship to deliver an unparalleled listening experience.

At the core of the XA200.5 is its Class A topology, which is celebrated for its ability to produce warm, rich sound with minimal distortion. The amplifier is capable of delivering 200 watts of power into an 8-ohm load, and it can double that output for 4-ohm loads, making it suitable for driving a wide range of loudspeakers, from modest bookshelf models to demanding floor-standing designs. This impressive power reserve ensures that the XA200.5 can handle dynamic peaks effortlessly, providing a sense of authority and control over the music.

One of the standout features of the XA200.5 is its proprietary "current source" design. This technology allows the amplifier to deliver musical dynamics with precision while maintaining a linear response across the audio spectrum. Pass Labs emphasizes the importance of low signal distortion, and the XA200.5 achieves this through meticulous engineering, including high-quality components and a robust power supply. The power supply not only supports the high current demands of the amplifier but also contributes to the overall stability and performance of the unit.

The build quality of the XA200.5 is exceptional, with a substantial chassis constructed from high-grade aluminum. This not only adds to its aesthetic appeal but also enhances durability and minimizes resonance, ensuring that the internal components function optimally. The amplifier features a distinctive design with large heat sinks that facilitate efficient thermal management, keeping the unit cool even during extended playback sessions.

Another notable aspect of the XA200.5 is its single-ended input configuration, which is designed to enhance musicality. This input sensitivity allows for direct connection to source components without the need for a preamplifier, ensuring a pure signal path. Additionally, the amplifier includes balanced input options for those who prefer using balanced connections.

In summary, the Pass Labs XA200.5 is a powerhouse of an amplifier that beautifully marries technological innovation and elegant design. With its Class A operation, proprietary current source technology, and exceptional build quality, the XA200.5 delivers a remarkable audio experience that is both impactful and refined, making it a top choice for discerning audiophiles.
