XP 20 Owners Manual Rev 0.4 13
PASS THRU: Pushing this button twice, sets the pre-amplifier to volume step 75 (0 dB)
and input 5. We have intentionally made this command a two-step operation such that
you will not accidentally select this command with its associated high volume.
Pressing the button once will bring up the question of “YES” on the display. If you are
sure that you wish to access the pass through function, press the button a second time
or continue to hold the button in the depressed position. There is a time-out built into
this command sequence.
If you do not confirm the “pass thru” command within 7 seconds then the command
sequence aborts and the XP-20 resorts to its previous status. 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.
DISPLAY: The default setting for the display is “bright”, pressing the “DISPLAY” button
once changes the display to it’s “dim” or “low intensity” setting, pressing the button a
second time selects “off” for the display. When “off” is selected any other control
function will cause the display to indicate product operational status for approximately 7
seconds and then the display will once again blank.
Pressing the “DISPLAY” button a third time cycles back to a “bright display”.
Design Comments
We recommend the use of the balanced output mode where possible. Balanced input
to power-amplifiers will typically retain the character of the input mode, but offers less
distortion, less noise, more gain, and more voltage swing, without compromising the
sound
