the front panel. Input 5 (TAPE IN) is deliberately not available
through the tape output connection. The tape input is designated
for use with a tape recorder if you have one, and we have arranged
that it will not place its output on the tape out, which will prevent
you from accidentally creating a feedback connection with your tape
machine.
The main outputs are located at the left-hand side (viewed from the
rear) of the rear panel, two male XLR connectors, and two RCA
connectors, “R” (right) and “L” (left). The RCA connectors’ ground
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 rear 5-way binding post can be used to turn on any X series
power amplifier.
In application the X2.2’s front panel controls and simple LED
displays 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 and playtime will add much to your
ultimate enjoyment of this exceptional Pass Labs product.
The front panel of the X2.2 has all its control functions moderated
by five momentary pushbuttons. From left to right these buttons are
labeled input, tape, volume (down), volume (up) and mute.
The input button has four associated blue LED’s located directly
above the input switch. When the uppermost blue LED is lit it
indicates that you have selected input number 1. With an additional
push of the input selector button the second uppermost LED will
be on, indicating you have selected input number 2. So it goes, the
same pattern follows with input 3 and 4. An additional push of
the input selection button when you are on input 4 will cycle the
preamplifier back to input 1.
The second button from the left controls the tape loop, a blue LED
directly above this switch indicating the status of this particular
function. When the tape loop is active, this LED will be lit.
Immediately to the right of the tape loop control are the two volume
