WARNING

• Make sure that the loudspeaker is securely installed in a stable position to avoid any injuries or damages to persons or properties. For safety reasons do not place one loudspeaker on top of another without proper fastening systems. Before hanging the loudspeaker check all the components for damages, deformations, and missing or damaged parts that may compromise safety during installation. If you use the loudspeakers outdoors avoid spots exposed to bad weather conditions.
• The external wiring connected to speaker output terminals requires installation by qualified personnel only. Once the equipment is installed, prevent access to the connectors to unqualified personnel. Only use the accessories and configurations described in this manual, and proceed under the instructions given in the manuals for the accessories. dBTechnologies will not accept any responsibility for damages caused by inappropriate accessories or additional devices.

MECHANICAL AND ACOUSTIC FEATURES

DIMENSIONS AND WEIGHT

• The IS25T has been designed with particular attention to optimizing the overall dimensions and ease of handling. The unit weighs only 7 kg.
• The main dimensions are 152 x 485 x 240mm [W x H x D].

ACOUSTIC COVERAGE

• The horn is designed to give a coverage of 100° horizontally and 60° vertically.
• The coverage pattern of the speaker can be inverted to suit different applications by rotating the horn using this simple procedure:
• unscrew the screws securing the grille and remove the grille
• unscrew the four screws securing the horn to the cabinet
• rotate the horn through 90° either in a clockwise or anti-clockwise direction; the screws holes serve as reference points
• fix the horn in the new position by screwing the four screws back into their holes
• fit the grille and tighten the screws to secure it to the cabinet

ACOUSTIC COVERAGE OF SPEAKER WITH HORN ROTATED

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).

MAIN ACCESSORIES AND EXAMPLES OF USE

CAUTION!

• Installation types other than those illustrated here are not allowed.
• Installation must be carried out by qualified personnel.
• If the speaker is to be wall mounted, the fixings used by the installer must be suitable for the type of wall to ensure stability and safety.

• In the case of pole mounting, make sure that the stand is placed on a flat, level surface, otherwise additional safety fixings will be required.
• For vertical installation, the bracket WB-VIOX205V allows precise adjustment of the tilt angle when the speaker is wall mounted, suspended from a truss (e.g., using an eyebolt or TV-SPIGOT, not included) or mounted on a stand (using a 35 mm adapter for pole mounting). Refer to the relevant instructions for further details.
• For horizontal installation, the bracket WB-VIOX205H allows precise adjustment of the tilt angle when the speaker is wall-mounted. Refer to the specific instructions for this accessory for further details.
