• According to the standards EN 55103 this equipment is designed and suitable to operate in E3 (or lower E2, E1) Electromagnetic environments. This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: —Reorient or relocate the receiving antenna. —Increase the separation between the equipment and receiver. —Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. —Consult the dealer or an experienced radio/TV technician for help. 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 di not place one loudspeaker on top of another without proper fastening systems. Before hanging the loudspeaker check all the components for damages, deformations, missing or damaged parts that may compromise safety during installation. If you use the loudspeakers outdoor avoid spots exposed to bad weather conditions. Contact dBTechnologies for accessories to be used with the speakers. dBTechnologies will not accept any responsibility for damages caused by inappropiate accessories or additional devices. WARNING Changes or modications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.

The subwoofer will turn on after inserting, turning and connecting the powerCON TRUE1® connector to the power supply. For subwoofer use optimisation in given congurations, the control panel displays the following:

1. Link (the signal present at OUTPUTS is the one applied to the woofer)

2. Xover (the signal present at OUTPUTS is ltered with a crossover

frequency of 120 Hz, for daisy chain to a speaker, such as B-HYPE and OPERA)

2. Reverse (reverse polarity, useful for wavefront optimisation through

acoustic wave phase reversal)

USAGE WITH SPEAKER IN A STACK

A speaker may be installed directly on 915 or 918 subwoofer by means of a DS2-S 35 mm diameter mini-pole (e.g. series: INGENIA, B-HYPE, OPERA). An additional fastener is required.28 SUB 915 - SUB918 Code 420120322 REV. 1.0

1. Check that power supply is present upstream of the installation.

2. Ensure that the power supply cable is properly plugged in.

1. Check that the input connection of the audio signal is correctly performed.

2. Check the cables for damage.

3. Ensure that the mixer or audio source is on and an output signal is present.

4. Check the general level through the "Input Sensitivity" control.

1. Check the cables for damage and replace them as required (a damaged cable may lead to signal loss or

2. Check that the settings on the control panel are correctly set.
