MECHANICAL FEATURES

The top and bottom of the speaker are equipped with attachment fittings for the mounting brackets (optional). These attachment fittings allow adjustment of the tilt angle with the speaker in the horizontal position, and rapid fixing in the vertical position. See the ACCESSORIES section.

PROTECTION AGAINST SOLID OBJECTS AND LIQUIDS (IP RATING)

The speaker is protected against the ingress of solid objects and liquids with a rating of IP32 as defined by EN 60529. To guarantee this specification is met, the speaker must be installed horizontally or vertically facing downwards with a tilt angle of at least 15° to the vertical. The cable connecting the speaker to the amplifier must have a diameter of at least 8mm (0.31 inch).
Failure to comply with these installation prescriptions could adversely affect the declared protection ratings.

CONNECTIONS

CONNECTING AND LINKING THE AUDIO SIGNAL
The audio input and link to another speaker are connected via Euroblock (Phoenix) connectors; the connectors are protected under a metal panel that is easily removed by unscrewing the four screws securing it to the cabinet.
Connect the audio source (e.g., from an amplifier or another speaker) to the INPUT terminal using the provided female connectors, respecting the polarity markings next to the connectors (positive to positive, negative to negative). The audio signal can be linked to another speaker in a similar way: connect the LINK output of the speaker to the INPUT terminal of the next speaker respecting the polarity (positive to positive, negative to negative).
