XA200.5 Owner’s Manual

So the amplifier is sitting there unconnected.

Make sure that the rear panel power switch/breaker is off (down). Plug the AC cord into the back of the amplifier, and then into the wall. Then turn the power switch/breaker on (up). The lights in your house will dim for a moment as the power supply charges the capacitors.

If your amplifier uses a circuit breaker and not a fuse, please note that this circuit breaker is not a “safety device” or “emergency disconnect” for this product. It will provide current limiting which will protect the amplifier, but it does not provide personal shock protection in the manner of a ground-fault interrupter. One more reason why it is important not to defeat the Earth connection of your power cord.

On the front panel, the “Standby” LED indicator should be glowing blue, indicating that AC power is available and the capacitor banks are charged. If the “Power” LEDs are lighting the meter, use the front panel stand-by button to go to stand-by mode.

Now turn off the rear power switch and unplug the AC power cord from the wall while you connect the speakers and inputs.

Check to make certain that the loudspeaker cables aren’t shorted at the loudspeaker end, connect speaker cables to the output binding posts on the amplifiers, observing correct polarity. The output binding posts will accept either bare wire or spades. (Regulatory agencies in many countries have banned binding posts that will accept a banana plug, forcing us to abandon this option.) Make sure that your speaker wires only attach to the outputs of the amplifier, not to each other and never to the amplifier case.

Remember the warning about treating the output connections as ground, particularly if you are using a powered subwoofer with this amplifier. If you need a ground, use the one provided specifically on the rear panel of the amplifier.

The amplifier may be driven single-end or balanced, your choice. Single-ended input will always occur through the RCA connector and balanced input will always occur through the XLR connector.

Again, if you drive the amplifier single-ended then leave the supplied jumpers in place between pins 1 & 3 on the input XLR.

On the XLR connector pin 1 is ground, pin two is positive input and

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.
