Overview
The XVR1 electronic crossover network is the result of several years research into the actual needs of loudspeaker designers. It is a stereo two-way biamplification network which can be combined with additional networks to form either simple or very complex crossover networks with virtually unlimited adjustability of filter characteristics.
Each high and low pass filter is user configurable as 6, 12, 18, or 24 dB per octave slope, and each "pole" of the four slope settings is independently adjustable from 22 Hz to 18,000 Hz.
In addition, there are three (3) independent Q (sharpness) controls for each filter. This gives something like 28 million possible settings per filter.

About the brand
Based in Foresthill, California, USA, Pass Labs was founded by Mr. Nelson Pass, a well known figure in the high end audio community.
Although Pass Labs has only been around for a decade, they have collected more awards than many companies who have been around a lot longer.
Mr. Pass is known for unique and innovative, as well as practical, circuit designs. Pass' first designs, in the Aleph line, were single-ended pure Class A solid state. The current Pass Labs "X" series amplifiers use a distortion canceling balanced audio signal circuit, and continue to receive critical acclaim. Today Pass Labs makes amplifiers, preamplifier and speakers.
