!6 [INPUT] A/B connectors
Two types of input connectors are provided for both channels
A and B. In Single mode or Parallel mode, the input connec-
tors of channel A are used.
• XLR jack
XLR type 3-31 jack.
The polarity is shown below (IEC60268).
• Phone jack
Balanced TRS phone jack.
The polarity of the connections is shown below.
!7 [SPEAKERS] A/B terminals
Output terminals for speakers. Three types are available
(below).
• Neutrik NL4MD speakON connector
• Binding post connector
• Phone jack
!8 [AC IN] connector
Connect the supplied AC power cord. First connect the AC
power cord to the connector on the amplifier, and then plug it
into an appropriate AC power outlet. Secure the AC power
cord with the AC plug clamp to prevent accidental disconnec-
tion from the connector.
!9 Exhaust ports
Exhaust vents for the cooling fan. Make sure to not block
these ports.

NOTE
The XLR input jack and the phones input jack of each channel are
connected in parallel. The signal input from an XLR jack can be
output from the phone jack and input to another amplifier. Only
one of the jacks can be used as an input jack at one time; the sig-
nals from the jacks cannot be mixed.

NOTICE
• Do not touch the terminals or metal parts of cords connected to
the terminal. If connecting speakers to multiple connectors of
the same channel results in a parallel connection, make sure
that the total impedance of the speakers to be connected is not
excessively low.
• The PX amplifier adopts BTL (Balanced Transformer Less)
amplifier circuits. Connecting both terminals of channel A and
channel B and contact between the terminal and the chassis
may cause a failure or malfunction. Be careful not to connect or
contact the two by mistake.
NOTE
In Power Boost mode, the output terminals of channel A are used
(PX5/PX3 only).
