Pass Labs Introduces New Flagship Preamplifier

Pass Laboratories introduces the XP-30 Preamp, the finest sounding preamplifier the company has ever produced. Using a unique triple-chassis structure, the XP-30 brings listeners closer to the emotional power of live performance.

XP -30 with Unique Triple Chassis and External Power Supply Powers Two to

Six Amps and Brings Listeners Nearer the Emotional Power of Great Music

FORESTHILL, CA, Sept. 21, 2011 - Pass Laboratories, Inc., an audio innovator renowned for its unique high -performance products, proudly introduces the XP -30 Preamp, the finest sounding, highest performing preamplifier the company has ever produced, and a a new flagship to its line.

Using a unique triple -chassis structure, the XP -30 delivers leading -edge audio that brings listeners closer to the emotional power of live performance, recalling the joy of discovery they experienced listening to great music, whether onstage or in earlier recordings. The XP -30 joins Pass Labs' XP -10, XP -15, XP -20 and XP -25 in its acclaimed XP series of preamps and phono preamps.

In measurable performance, the XP -30 exceeds its predecessors in generating lower noise levels, better crosstalk specifications, and greater dynamic range, producing music exhibiting more resolution, more dynamics, and a better sense of space and dimensionality. It delivers the ultimate sonic experience a two -channel audio system can provide under any and all conditions.

The XP -30 is a modular preamplifier consisting of one power supply and control chassis and two additional chassis, each serving one channel. It is typically supplied as a two -channel product although it can be configured to serve anywhere from one to six channels, enabling but not requiring the design of very large or unusual speaker systems.

Each channel provides master and slave outputs. A knob on the front of each of the two gain stages sets the slave output to be equal to or less than the master level; all connected gain stages respond to a master level adjustment on the control panel. Both single -ended and balanced outputs have the same gain structure and may be used interchangeably. The control chassis also supports a mono function that allows almost limitless multi -amplifier functionality.

A new low -noise volume control covers a range of 100 dB in 1 -db increments.

The external power supply is large enough for a small power amplifier. Its chassis houses a pair of highly efficient, low -noise Plitron transformers. The circuits use dual mono topologies that supply ample current and excellent voltage stability to the gain stages, as well as inherently better noise suppression and filtering. Very low -noise, high -speed parts further enhance its performance.

The power supply enhancements allow music to flow through the XP -30 with a dramatically greater sense of ease, spatial development and dynamic contrast than through any other of Pass Labs' preamplifiers.

The XP -30 Preamp is available now from authorized Pass Labs dealers at a suggested price of $16,500 (U.S. MSRP).
