XA60 Owner’s Manual

We have provided a standard IEC power cord that fits into the standard 15 amp IEC receptacle at the rear of the amplifier chassis. Two XA60’s may be run on a single 15-amp circuit in conjunction with other audio components. 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 protection from irritating ground loops.

As a safety issue 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.

The amplifier’s voltage and current rating are indicated on the rear panel. It will be either 240 volts, 220 volts, 120 volts or 100 volts, all units protected by a type 3-AG slow blow fuse of the appropriate ampacity. The operational voltage is not user changeable. Transformers are input voltage specific and their change is not a trivial matter.

The frequency rating of the AC line source is 50 to 60 Hz in all cases. Please verify that the amplifiers indicated voltage requirements are consistent with the supplied voltage and current at your location.

Looking at the rear panel you will see the IEC AC power cord receptacle, a power switch, type 3-AG fuse holder, two pairs of output connectors which allow for speaker bi-wiring, a single pair of 5 way connectors for remote turn-on, a single RCA input connector and a single XLR balanced input connector.

Make sure that the rear panel power switch is off (down). Plug the AC cord into the back of the amplifier, and then into the wall. Then turn the power switch on (up). The lights in your house may blink when the power supply charges the capacitors. (Note: The power switch is never to be used as a “safety device” or “emergency disconnect” for this product. This device will not provide comprehensive personal shock protection in the event of a reversed hot / neutral, lack of grounding or other improper wiring of the supplied mains voltage.)

XA60 specifications

Pass Labs XA60 is a high-performance audio power amplifier that epitomizes the pursuit of sonic purity and fidelity in the realm of high-end audio. It is the entry-level model in the esteemed XA series, but still incorporates many of the advanced technologies and features found in its more powerful siblings. Designed with a focus on delivering an immersive listening experience, the XA60 combines state-of-the-art engineering with superior craftsmanship.

One of the key features of the XA60 is its Class A topology, which ensures that the amplifier operates in the linear region for the entirety of its output range. This design lends itself to a warm, natural sound that captures the nuances of music without the harshness often associated with other amplifier classes. The XA60 is capable of delivering 60 watts per channel into an 8-ohm load, making it ideal for driving a variety of loudspeakers, including high-efficiency models.

The amplifier employs Pass Labs' patented "Pure Class A" output stage, which utilizes a unique biasing method to minimize crossover distortion. This innovative approach enhances the overall sonic clarity and dynamic range, allowing the XA60 to reproduce even the most complex musical passages with ease. Additionally, the amplifier is characterized by its dual-mono design, isolating the left and right channels to reduce crosstalk and interference, which ultimately results in a more focused soundstage.

Another standout characteristic of the XA60 is its massive power supply. The highly refined power supply includes large heatsinks and high-quality components that help maintain stability and reduce noise during operation. The robust thermal management ensures that the amplifier remains cool, even during extended listening sessions, thus preserving the integrity of the sound.

The build quality of the XA60 is nothing short of exceptional. Housed in a sturdy chassis, the amplifier features premium-grade connectors and a simple, yet elegant aesthetic that is typical of Pass Labs products. The thoughtful design not only ensures durability but also aids in minimizing vibration, further enhancing acoustic performance.

In summary, the Pass Labs XA60 amplifier represents a harmonious blend of advanced technologies, exceptional sound quality, and impeccable craftsmanship. With its Class A operation, dual-mono architecture, and high-quality components, the XA60 provides a nuanced, engaging listening experience that appeals to audiophiles seeking both precision and warmth in their audio systems. Whether used in a dedicated listening room or as part of a larger home audio setup, the XA60 is engineered to deliver music as it was meant to be heard.
