Pass Labs Introduces the INT-150 Integrated Amp, Boasting 150 No-Nonsense Watts/Channel

Company’s First Integrated Amp Features Low-Noise Super-
Symmetry Circuitry, Plus Outstanding Audiophile Performance

FORESTHILL, CA, Dec. 11, 2007 — Pass Laboratories, Inc., an audio innovator renowned for its unique high-performance products, will introduce the INT-150 Integrated Amplifier at the 2008 International Consumer Electronics Show, Jan. 7, in Las Vegas. The INT-150 expands the ranks of audiophile products to a broader spectrum of demanding consumers with a no-nonsense, user-friendly amplifier that delivers outstanding performance and a high level of user satisfaction.

The INT-150 is Pass Labs’ first integrated amplifier. Based on the company’s acclaimed X-150.5 Stereo Amplifier, the INT-150 embodies the design technology and refinements — including patented Super-Symmetry circuit — of the X150.5 and Pass Labs’ larger X.5-Series amplifiers.

In performance, the INT-150 boasts an excellent dynamic range and fast response. Rated at 150 watts-per-channel into 8 ohms, and 300 watts into 4 ohms, it moves easily from black background to explosive transients, then back again, adding realism and authenticity to recorded materials. It performs with authority and stability regardless of loudspeaker load. Smooth and transparent, the INT-150 provides clean, expansive sound at an affordable price.

The Super-Symmetry topology developed by Nelson Pass improves performance by precisely matching characteristics of the two halves of a balanced amplifier. To the extent that distortion and noise can be made to appear identical at the two output connections, they will not be detected at the balanced output. In conventional amplifiers, ordinary matching techniques can achieve improvements by a factor of about 10 under ideal conditions. In the INT-150, Super-Symmetry lowers distortion and noise by an additional order of magnitude.

Input, output and AC connectors are on the rear of the amplifier. The main power switch is also on the rear, but a convenient standby switch is available on the front panel. The INT-150 accepts four single-ended inputs via RCA connectors, and two balanced XLR inputs. The speaker outputs are equipped with heavy-duty, international safety-rated, five-way binding posts.

In appearance, the INT-150 resembles the X150.5, without the meter. The faceplate is machined from thick aluminum stock, then anodized instrument-gray. The satisfyingly solid remote is also made from machined aluminum, and visually matches the front of the amplifier.

The INT-150 Integrated Amplifier is available now from authorized dealers at a suggested price of $6,500. It can be seen with Pass Labs’ other outstanding products in Suite 140, Venetian Tower 29, during the show.
