circuit elements, independent of the single ended outputs. Tape
input communicates back to the input bus, independent of the XP-
20 volume control.
Balanced inputs and outputs are via XLR connectors. Single-
ended inputs and outputs are via RCA connectors. On the XLR
connectors, pin 1 is grounded, pin 2 is the positive signal, and pin
3 is the negative signal. Left channel RCA connectors are marked
with “L”. Right channel RCA connectors are marked with “R”. In
a similar fashion balanced XLR inputs and outputs are marked with
“L” for left and “R” for right channel.
The main outputs are located at the left-hand side (viewed from the
rear) of the rear panel, two male XLR connectors, and four RCA
connectors, “R” (right) and “L” (left). The RCA connector’s ground
(shell) is in parallel with pin 1 of the XLR outputs and the RCA hot
is fed from an independent summing junction that maximizes the X
circuit benefits. The RCA, single-ended, outputs are buffered from
the balanced outputs.
You may use both the single ended and balanced outputs at the same
time. On the XLR, pin 1 is ground, pin 2 is positive, and pin 3 is
negative.
The XP-20 has an onboard tape loop for those of you who like to
record, add a signal processor into the chain or simply need one
additional pair of RCA inputs to complete your music system. The
tape loop is available only from the remote control and is selected or
deselected by a single keystroke of the “Tape” button on the remote.
When you select Tape from the remote the display shows a lower
case letter “t” on the right hand side. When the letter “t” is showing
tape input is selected and other inputs are de-selected, regardless of
other settings you may have chosen.
Input and output connectors were carefully selected to withstand a
lifetime of frequent use.
The XP-20 gain chassis has a single pair of binding posts labeled
“Ext. Amp Turn-on”. A 12-volt signal is available at these binding
posts to control additional entertainment electronics. This
External Turn On feature was specifically intended to control Pass
Laboratories power amplifiers but may in fact control competitive
product with similar features. Check your power amplifiers owner
manual and specifications for particulars.
This function is only active from the hand held remote control.
