Pass Labs XP-20 guide

XP-20 Owner’s Manual

The Remote control operation is, or should be very intuitive in operation; we have attempted to make its operation as familiar as possible. Where applicable the remote mirrors the front panel controls.

POWER: As previously mentioned has no reality with the XP-20. This specific control functions has no effect on this product.

EXTERNAL AMP ON: The “external amp on” button supplies a 12-volt trigger voltage from the rear panel of the XP-20, which will control various pieces of auxiliary equipment. This function is intended to control Pass Laboratories power amplifiers. For specifics please see the instructions that accompany your power-amplifier. You may also call the Pass Laboratories factory for specifics.

MUTE: pressing mute once will quiet the pre-amplifier outputs; pressing mute a second time will return you to the previous volume control setting.

INPUT SELECTION: Pressing. 1,2,3,4,5 will immediately move the input selection to that input selection; volume and balance settings will not be disturbed.

BALANCE: Pressing balance left (<) or balance right (>) will increase the level in the left or right speaker, depending upon which button is pushed.

VOLUME: Pressing the increase (^) button or the decrease (v) button will shift the volume setting 1dB, holding a button down will increase or decrease the level until such time as you either release pressure on the button or reach the limits of the volume control.

PASS THRU: Pushing this button twice, sets the pre-amplifier to volume step 75 (0 dB) and input 5. 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 button must be pressed again to exit “Pass Thru” and unlock the other command selections.

TAPE: Pushing this button once selects the single ended “Tape” as your sixth input, pressing a second time deselects the tape input and defaults back to the indicated input. When “Tape” is selected a lower case letter “t” will appear on the right hand side of the display.
