X1 Owner’s Manual

totally transparent. When the user chooses “Unity” this sets the X1’s gain to the low (+4dB) setting, regardless of how it was previously configured. When at Unity both left and right level controls on the X1 will have a displayed value of 24, and any previous balance settings will be lost. Both of these default conditions are intentional, and intended to make the most advantageous use of your source electronics. You may also set any of the four inputs to unity (0dB gain) by selecting low gain and setting the volume to indicate 24 on the front panel display.

Before selecting this option, it is imperative that the input device on input number 4 has its gain set to minimum. Failure to follow this precaution could result in a volume level intolerable to both ears and speakers. To further protect your hearing and valuable audio equipment, Wayne has designed this product so that the volume setting of the preamplifier will always revert to zero as you change inputs. We trust that the remote control, with its four buttons that duplicate those of the preamp front panel will enable you to quickly select inputs and establish levels of output.

1)Circuit simplicity and a minimum number of components is a key element. The fewer parts in series with the signal path, the better. Adding more parts and gain stages may improve measured specs, but will seldom improve the perceived sonic quality.

2)The characteristic of gain devices and their specific use is important. Individual variations in performance between like devices are important, as are differences in topological usage. All signal bearing devices contribute to the degradation, but there are some different characteristics that are worthy of attention. For example, smooth low order nonlinearities are additive in quality, bringing false warmth and coloration, while abrupt high order nonlinearities add harshness and false brightness.

3)Maximum intrinsic linearity is desired. This is the performance of the gain stages before feedback is applied. Experience suggests that feedback is a subtractive process; it removes information from the signal. In many older designs, poor intrinsic linearity has been factored out by large application of feedback, resulting in loss of warmth, space, and detail. The trick is to get good performance without this excessive reliance on feedback.

The art of high end audio design lies in the approach to combining these elements to get high reliability and simplicity, high quality measured performance, and high quality subjective performance. It

X1 specifications

Pass Labs X1 is a high-end preamplifier that embodies the very essence of cutting-edge audio engineering, combining advanced technologies with superior craftsmanship to deliver an exceptional sonic experience. Known for its neutral and transparent sound signature, the X1 is designed to serve as the heart of a high-fidelity audio system, providing precise control over volume and input selection while ensuring signal integrity is maintained.

One of the defining features of the Pass Labs X1 is its fully differential architecture. This design not only enhances noise rejection but also minimizes distortion, resulting in a clean and accurate reproduction of music. The X1 employs a direct-coupled topology, allowing for a wider bandwidth and increased dynamic range, essential for capturing the subtleties of any audio performance.

The X1 also integrates a sophisticated power supply, utilizing separate transformer windings for the analog and digital circuits. This isolation reduces cross-contamination between sections, which is crucial for maintaining the integrity of the audio signal. The power supply is supplemented by high-quality capacitors and regulators, ensuring that the preamplifier operates with stable voltage and low noise.

In terms of connectivity, the Pass Labs X1 offers a comprehensive array of inputs and outputs, including balanced XLR and unbalanced RCA connections. This versatility allows it to interface seamlessly with a variety of sources and amplifiers, making the X1 suitable for both audiophile and professional environments. Additionally, the preamp features a remote control for added convenience, allowing users to adjust settings from a distance without compromising sound quality.

Another notable characteristic of the Pass Labs X1 is its rugged build quality. Constructed using high-grade materials and meticulously tested, the unit not only looks elegant but is designed to last, providing years of reliable performance.

Ultimately, the Pass Labs X1 is a testament to the brand's commitment to excellence in audio reproduction. Whether used in a dedicated listening room or as part of a professional setup, the X1 delivers a listening experience that is both immersive and true to the original recording, making it an invaluable component for any serious music enthusiast or audio engineer.
