WELCOME! PRODUCT OVERVIEW USER REFERENCE Thanks for purchasing a product designed and developed in Italy by dBTechnologies! This ergonomic and versatile active speaker is the product of several years of experience and innovation in the sound reinforcement industry, using cutting-edge sound, electronic and material research solutions. The new active OPERA speakers are equipped with a 1" compression driver (output: 1.4”) for the high section. A 10", 12", and 15" transducer (voice coil: 2") for medium-low frequencies, is tted on OPERA10, OPERA12, OPERA15 respectively. These speakers main features include: To make the most of your OPERA speaker, we recommend that you:

• an ergonomic, compact and versatile project that can be used in monitoring for small live contests

• acoustic asymmetry of horn for high frequencies, optimized for efcient use in different indoor and outdoor situations

• reliable and silent amplier that does not require active ventilation

• input (up to 2) versatility of use, for instance for the amplication of a voice and an instrument at the same time

• versatility of output connection, for audio relay of the mixed signal or LINK

• presets that can be selected for an equalization through DSP for any type of use

• Read the quick start user manual included in the package and this user manual thoroughly and keep this manual during the whole life of the product.

• Register your product at http://www.dbtechnologies.com under “SUPPORT”.

DIMENSIONS SOUND COVERAGE The OPERA series has been designed with the intent to optimise weight and dimensions. The cabinet is lighter but more resistant, and features 2 handles, one on the side and one at the top, for easy handling. For a quick comparison of the 3 models, the overall dimensions are the following: OPERA10 - 300 mm (L), 552 mm (H), 301 mm (W) OPERA12 - 349 mm (L), 642 mm (H), 350 mm (W) OPERA15 - 420 mm (L), 772 mm (AH), 419 mm (W) The special design of the horn, shown in the gure, is common for all 3 models. In horizontal, the coverage is differentiated between the value of 85° (upper part) and 120° (lower part). This is to optimise sound emission, for example during vertical installation in reverberant environments. The special design of the horn, shown in the gure, is common to the 3 models. The overall vertical opening (85°) is asymmetrical, to increase the sound pressure of the horn at long distance. In case of use with monitoring function or in case of horizontal positioning (wall-mounted) of the speaker, take these data into account so as to calculate the correct coverage of the environment.

COD. 420120247 REV. 1.1 FEATURES OF THE AMPLIFIER AND CONTROL SECTIONS Class D digital amplier is at the heart of the OPERA series. The system is silent and does not require a fan cooling. The system is controlled by a dedicated powerful DSP that manages the different parameters. The sound amplication power is 600 W RMS for all models. The DIGIPRO G3 panel is made up of: WARNING!

• Protect the unit from moisture.

• Never attempt to disassemble the amplier in any way.

• In the event of a malfunction, remove power supply immediately by disconnecting the unit from the power mains and contact an authorised repair centre.

• Input, Output and Control Section

• Power Supply Unit Section English

• Never remove the product's front protection mesh. In order to prevent electric shock hazard, in the event of accidental damage or replacement of the protection mesh (which must be carried out by a service center), disconnect the power supply immediately. Do not connect to the power supply while the mesh has been removed. WARNING!24

It includes the 8-position "DSP Preset" rotary switch, the "Limiter" and "Signal / ON" LED indicators and the "ground lift" switch.

Equipped with connector for balanced cable (XLR), it also includes the "Out Routing Selector", required to differentiate the output inputs in case of connection to a second speaker.

4. DSP PRESET - TABLE

The selectable presets are shown in this table as a reminder. S1 - Club, suitable for a medium-small indoor environment S2 - Vocal, optimises for vocal playback and performance S3 - Bass reduction, with attenuation of low frequencies, for use in reverberant environments S4 - Playback, optimised for music playback (such as MP3 reader) S5 - Bass boost, suitable to emphasise low frequencies Recommended presets for monitor use (wedge): W1 - Wedge Vocal, to be used with monitor (wedge) position and vocal performance W2 - Wedge Playback, to be used in monitor (wedge) position and playback of a music programme Preset that excludes any equalization: FLAT - to be set if no equalization is required

2. "CH2" INPUT SECTION

Provided with Combo connector to connect cables with XLR and TRS (balanced and unbalanced) connectors, includes channel level adjustment and a switch to adjust input impedance (“Line” or “Instr”). “Instr” refers to a high impedance such as that of a guitar or bass.

1. "CH1" INPUT SECTION

Equipped with a Combo connector to connect cables with both XLR and TRS connectors (balanced and unbalanced), it includes the regulation of the channel level and a switch to adapt the impedance to line level ("Line"), or to microphone level ("Mic"). English25

Input for VDE connector for connection to the mains.

Switch for turning device ON or OFF.

POWER SUPPLY UNIT SECTION

WARNING! Do not use the speaker for long periods of time when the Limiter LED is steady on or constantly blinking, as this indicates that the module is operating under excessive stress under distortion conditions. Use only high quality and in good condition cables. The use of poor quality or damaged cables could affect speaker operation. English26

COD. 420120247 REV. 1.1 MIXER / LINE MICROPHONE INSTRUMENT (HIGH IMPEDANCE) INSTRUMENT (LINE IMPEDANCE) LINE It is possible to connect up to 2 inputs in the input and control section at the back of the speaker. Following are only few examples of conguration used (1 input and 2 inputs). CH1 (1): it is possible to connect a source through a cable with balanced or unbalanced connector (TRS, XLR). Select the input type using the Input Sensitivity Switch. In particular, in case of microphone input, select "MIC". CH2 (2): it is possible to connect a source through a cable with balanced or unbalanced connector (TRS, XLR). Select the input type using the Input Sensitivity Switch. In particular, in case of input with high impedance, such as the one of a guitar or a bass guitar, select "Instr". Instruments or devices with line impedance (such as a keyboard or a stereo player) require instead a "LINE" setting. Adjust the level of each connected channel. Once inputs are connected, select the correct DSP preset (1). In case of problems related to ground loops, it is possible to solve the problem by setting the relevant selector (3) to the correct position, as shown below. English28

• Connect the power cable to the socket (7), then set the turning on selector (6) to ON. The Limiter LED (3) blinks briey.

POWER SUPPLY CONNECTION

POWER SUPPLY WARNING! Use only good quality cables. Replace any damaged cable to prevent malfunctioning and sound poor quality. CONNECTING THE OUTPUTS OF MULTIPLE MODULES (audio daisy chain) It is possible to connect the output of an OPERA speaker to a second speaker using a cable with XLR balanced connector, which connects the output (2) of the rst speaker to the input (5) or (4) of the second speaker. Set the relevant selector to "LINE". The Out Routing Selector (2) in "CH1 link" position allows providing the output of the second speaker with only the signal coming from the CH1 (5) channel. In the "Mix Out" position, it allows the CH1 (5) and CH2 (1) channel mixing. English29

• Types of installation other than those here described are not allowed.

• Never use the handles to suspend the speaker

• Always check that the positioning is stable and that the installation does not pose a danger to people, animals or property

• Install on horizontal surface not inclinated, otherwise an additional mechanical fastening or a belt fastening is required to correctly x the installation.

1 OPERA speaker can be installed on a tripod stand, coming as standard option with a 35 mm diameter pole. The maximum allowed height between the speaker base and the oor is 160 cm. WARNING!

• Use a suitably sized stand with the central leg pointing forward to provide appropriate stability. Through the installation with the DS-2S accessory, it is possible to use 1 OPERA directly on subwoofer provided with M20 hole.

INSTALLATION ON SUBWOOFER WITH POLE

It is possible to use only one speaker mounted on a 35 mm diameter pole. The maximum allowed height between the speaker base and the oor is 160 cm. In case of use of DVA S08DP or SUB28D an additional mechanical fastening or a belt fastening is required to correctly x the installation. English30
