XP-20 Owner’s Manual

In application the XP-20s front panel controls and alphanumeric display are quite straight forward, and intuitive. We encourage you to become familiar with their operation prior to establishing any input connections with this unit. Experience indicates that engaging in a few minutes of exploration will add much to your ultimate enjoyment of this exceptional Pass Labs product.

The left most button on the front panel is Mute. Pressing this button toggles between mute on and mute off. Mute on removes signal from the output of the preamp.

(The standard 2 volt source component, with the pre-amp set to 0 dB, will drive most power amps to full rated output.)

As an added precaution when “pass through” is selected the volume ramps upto 75. This is to prevent nasty surprises when “pass thru” is selected accidentally. The ramp up sequence can be stopped at any time by hitting any button on the remote.

The theater “Pass Thru” function bears special attention, this function is only available as direct access through the hand held remote control. This function is associated only with input number 5 and has two positions selected with the “pass thru” button on the
