XP-20 Owner’s Manual
We sincerely believe these are simply the best sounding pre-amplifiers
Pass Laboratories has ever built! Simply put the XP products deliver
the experience of a past musical event in a more believable sonic
panorama than anything we have previously brought to market.
Thank you for listening and giving us the opportunity to prove this
claim.
There is an Extremely Small (but Non-zero) Chance That, Through
a Process Know as Tunneling, This Product May Spontaneously
Disappear from Its Present Location and Reappear at Any Random
Place within the Universe, Including Your Neighbor’s Domicile.
The Manufacturer Will Not Be Responsible for Any Damages,
Inconvenience or Mental Anguish That May Result.
There is a much higher probability that when you first plug your
new pre-amps power supply into the wall and listen to your favorite
selections that you will not be experiencing the full measure of
performance this product is capable of. These are high bias Class
A topology circuits and their performance is largely temperature
dependent.
We expect these circuits to heat up slowly through normal operation,
do not attempt to augment that heating by any artificial means.
Temperature and performance will slowly stabalize over the first 24 -
48 hours of operation and thereafter be at their sonic best. Be aware
however that if you unplug or otherwise remove power from the
unit that the warm up period starts afresh. Please give this product
at least 24 hours initial warm up time before attempting any critical
listening.
A typical current draw for this product is 25 watts or less; the XP-
20’s are designed to be powered up 100% of the time.
So much for the philosophy, physics and advantages, lets play music.
Please read and understand the operational instructions and safety
issues associated with this product. We go through great effort to
make a soundly engineered, and supurbly performing rugged product
of lasting duribility. We understand that things infrequently go
wrong, if you have any questions or problems please contact either
your dealer or the factory, we are here to support the product and
you, the user.
