XP-20 Owner’s Manual

circuit elements, independent of the single ended outputs. Tape input communicates back to the input bus, independent of the XP- 20 volume control.

Balanced inputs and outputs are via XLR connectors. Single- ended inputs and outputs are via RCA connectors. On the XLR connectors, pin 1 is grounded, pin 2 is the positive signal, and pin 3 is the negative signal. Left channel RCA connectors are marked with “L”. Right channel RCA connectors are marked with “R”. In a similar fashion balanced XLR inputs and outputs are marked with “L” for left and “R” for right channel.

The main outputs are located at the left-hand side (viewed from the rear) of the rear panel, two male XLR connectors, and four RCA connectors, “R” (right) and “L” (left). The RCA connector’s ground (shell) is in parallel with pin 1 of the XLR outputs and the RCA hot is fed from an independent summing junction that maximizes the X circuit benefits. The RCA, single-ended, outputs are buffered from the balanced outputs.

You may use both the single ended and balanced outputs at the same time. On the XLR, pin 1 is ground, pin 2 is positive, and pin 3 is negative.

The XP-20 has an onboard tape loop for those of you who like to record, add a signal processor into the chain or simply need one additional pair of RCA inputs to complete your music system. The tape loop is available only from the remote control and is selected or deselected by a single keystroke of the “Tape” button on the remote. When you select Tape from the remote the display shows a lower case letter “t” on the right hand side. When the letter “t” is showing tape input is selected and other inputs are de-selected, regardless of other settings you may have chosen.

Input and output connectors were carefully selected to withstand a lifetime of frequent use.

The XP-20 gain chassis has a single pair of binding posts labeled “Ext. Amp Turn-on”. A 12-volt signal is available at these binding posts to control additional entertainment electronics. This External Turn On feature was specifically intended to control Pass Laboratories power amplifiers but may in fact control competitive product with similar features. Check your power amplifiers owner manual and specifications for particulars.

This function is only active from the hand held remote control.

XP-20 specifications

The Pass Labs XP-20 is a high-performance preamplifier that embodies the sophisticated engineering and design philosophies of its founder, Nelson Pass. Renowned for its exceptional sound quality and performance, the XP-20 is an evolution of its predecessor, the XP-10, and is designed to meet the needs of audiophiles and music lovers who demand the very best in their audio equipment.

At the core of the XP-20 is a fully balanced circuitry design, which allows for improved signal integrity, reduced noise, and enhanced dynamic range. This balanced topology not only minimizes distortion but also ensures that the audio remains pure and true to the source material. The preamplifier features dual differential gain stages, which contribute to its remarkable clarity and transparency, making it a perfect partner for high-end power amplifiers.

One of the standout features of the XP-20 is its extensive input and output options. The unit includes multiple single-ended and balanced inputs, ensuring compatibility with a vast array of audio sources, including CD players, turntables, and digital streaming devices. The outputs are equally versatile, allowing for easy connection to power amplifiers or active speakers.

Another key characteristic of the XP-20 is its massive power supply, which provides the necessary current and voltage to drive the preamp's demanding circuitry. This robust power supply is designed with low noise and high regulation, ensuring that the unit operates efficiently while maintaining sonic fidelity.

Furthermore, the XP-20 incorporates advanced volume control technology, allowing for precise adjustments without compromising audio quality. The volume control is designed to minimize signal degradation, which results in a more accurate representation of the music.

Thermal management is also a critical aspect of the XP-20's design. With substantial heatsinking and ventilation provisions, the unit remains cool even during heavy use, ensuring long-term reliability and performance.

The build quality of the Pass Labs XP-20 is exceptional. The chassis is solid and well-constructed, with an aesthetic that exudes elegance and professionalism. It's available in a sleek black or silver finish, making it a stylish addition to any audio system.

In summary, the Pass Labs XP-20 is a preamplifier that exemplifies high-end audio engineering. Its combination of balanced circuitry, versatile connectivity, robust power supply, and meticulous design make it an outstanding choice for those seeking to elevate their audio experience. Whether for critical listening or casual enjoyment, the XP-20 stands as a testament to Pass Labs' dedication to audio excellence.
