CONNECTIONS- Output to Top Boxes (Speakons™)
Output to Top Boxes
At the right side of the rear panel are the output
connections to the top box speakers. Note the color
coding scheme of the text labels for each Speakon
connector. The color coding corresponds with the
colors of the Mode Switch labels (Combination Mode
or Discrete Mode).
The upper Speakon is labeled MONO BIAMP OR CH1
and DISCRETE CH1 in two text colors indicating that
the function of the Speakon relies upon the position
of the Mode Selector Switch (see chart, below). The
upper Speakon has all four terminals wired and is
thus suitable for biamp use. Both CH1 and CH2
outputs are wired to the top Speakon. Do not use the
lower Speakon when using the upper Speakon for
biamp use.
The lower Speakon is labeled CH2 and DISCRETE CH2
in two different text colors indicating the same
functional reliance on the Mode Switch position. In
either Mode, this Speakon is wired to the Top Box
amplifier’s CH2 output. CH2’s output is also wired to
the upper Speakon’s 2+ and 2- terminals for biamp
applications. Do not use the lower speakon if using
the upper Speakon in biamp connection.
Each Speakon has a wiring chart (pinout) printed next
to it for easy reference. The pin numbers (1+, 1-, etc...)
correspond to the pin numbers marked on the
Speakon.
To connect a Speakon, insert the keyed plug into the receptacle
and twist counterclockwise to lock in place.
When the Speakon locks into place, an audible
“click” confirms connection.
Speakons provide a clean appearance, reliable electrical
connection and positive locking mechanism. To remove a
Speakon, pull the thumb-latch back and twist counterclockwise
1/8th turn.
