N. Output Connectors
This high-current output block is provided for output
connection. Its connectors accept banana plugs,
spade lugs or bare wire. The detachable output cover
(S) shown in Figure 2.5 is used to protect against acci-
dental short circuits and dangerous electrical shock.
DANGER: The outputs can produce lethal energy
levels! Do not change the output wiring unless the
amplifier has been off for at least 10 seconds.
Some international models include high-current bind-
ing posts for output connection rather than the output
block shown in Figure 2.3. The international binding
posts are shown below in Figure 2.4:

P. Balanced Phone Jack Inputs
A balanced ¼-inch (6.35-mm) phone jack for each
channel is provided on the PIP2-FXQ. These phone
jacks can be used for signal input, or for “daisy-
chained” output to other amplifiers. The phone jacks
may be used with either balanced (tip, ring and sleeve)
or unbalanced (tip and sleeve) wiring (see Section 3.3).
Note: The Channel 2 input is bypassed in either mono
mode.
Q. Balanced XLR Inputs
A balanced 3-pin female XLR connector is provided on
the PIP2-FXQ for input to each channel, or for “daisy-
chained” output to other amplifiers.
Note: The Chan-
nel 2 input is bypassed in either mono mode.
R. Input Ground Lift Switch
This ground lift switch is located on the PIP2-FXQ. It is
used to isolate the input signal grounds from the AC
(chassis) ground to help prevent ground loops that can
result in unwanted hum and noise.
S. Output Cover
This protective cover is provided to prevent an electri-
cal shock or short circuit at the output terminals.
O. PIP Module
The standard PIP2-FXQ is included with your amplifier.
It provides female XLR and ¼-inch (6.35-mm) phone
jack input connectors. Each pair of XLR and phone jack
connectors is wired in parallel, so the unused connec-
tor can be used as a “daisy chain” output to connect a
source to multiple amplifiers. Other
PIP and PIP2 mod-
ules can be used in place of the PIP2-FXQ to provide
additional features that customize the amplifier for dif-
ferent applications. Your amplifier is a
PIP2 amplifier,
which means it can take advantage of the many ad-
vanced features found in
PIP2 modules. In addition,
your amp can also use standard PIP modules (without
the PIP2 logo). See Section 8.1 for available PIP and
PIP2 modules.
