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.
