Cabling
The Galeo units are connected to each other and to the system rack by means
of 4-core NL4 Speakon cables. Use only high-quality 1:1 configured, flexible
speaker cables with Neutrik plugs. The impedance of both paths is 16 ohms
per loudspeaker box. Therefore, four units can be used simultaneously with a 4
ohm amplifier using 30cm loop thru cable, and up to eight Galeo on a 2 ohm
amplifier.
The Galeo Sub also has NL4 connectors, impedance is 4 ohms. Two Galeo
Subs can be used simultaneously (loop thru) with 2 ohm amplifiers.
For events necessitating permanent and extremely high demands on the power
amplifier’s performance, 2 ohm operation is not recommended, even if the
amplifier manufacturer has specified this mode of operation. Therefore, to
achieve optimum operational safety, combine a maximum of six Galeo units
per amplifier channel (2.7 ohm operation).
The pin configuration of the speakon sockets is printed on the connection
panels of the system rack and speaker cabinets.

In order to relieve strain on the Speakon connectors when using long speaker
cables during flying operation, use a cord grip, which can be attached to the
lower boreholes in the rear flying fitting or directly onto the flying frame.
Avoid using long cables, but if long distances are unavoidable, use 4 x 4mm²
cable instead of the normal 4 x 2.5mm² cable to keep voltage drop to a
minimum.
