ABOUT THE BALANCED INPUT
JACKS
q The PM-11S1 uses XLR connectors for the BALANCED
INPUT jacks. XLR connectors are widely used with profes-
sional equipment because of the following features.
• Incoming music signals are balanced, therefore they are
little affected by external noise.
• The detachable locking mechanism minimizes connec-
tor play and enhances connection reliability.
w There are two ways to connect the XLR connectors.
1.In the USA
2.In Europe
e The PM-11S1 adopts the USA circuitry. If the PM-11S1 is
connected via a balanced cable to a preamplifier or control
amplifier of European circuitry, signal phases will be re-
versed. To correctly align signal phases, switch the w and
e pins of one of the XLR connectors.
BEFORE MAKING CONNECTIONS
Your speaker system must satisfy the below conditions. If it
does not, the PM-11S1’s protective circuit will trip, whereby
preventing proper playback. In some cases, the amplifier and
speakers may be damaged.
• If using 1 set of speakers, total speaker impedance must be
4 Ω or more.
• If using 2 sets of speakers, total speaker impedance must
be 8 Ω or more.
WIRING SPEAKER CABLE
• Be careful not to short circuit in wiring speaker cables.
• Peel off the corting of speaker cable as shown below.
• Wiring with speaker cable.
