Frequently Asked Questions - Opera 12 DB Technologies

How to connect a microphone to the Opera 12?

Connect your microphone to the CH1 input (Combo XLR/Jack). Set the impedance selector to Mic and adjust the level with the appropriate Sens. control.

How to use DSP presets?

Turn the DSP Preset knob on the rear panel to choose from 8 positions: S1 Club, S2 Vocal, S3 Bass Reduction, S4 Playback, S5 Bass Boost, W1 Wedge Vocal, W2 Wedge Playback or FLAT (no equalization).

What are the monitoring (wedge) modes?

The W1 Wedge Vocal and W2 Wedge Playback modes are designed for stage monitor use (tilted horizontal position). They optimize equalization for voice or music playback in monitoring.

How to daisy-chain two speakers?

Connect the Balanced Out (XLR) of the first speaker to the CH1 or CH2 input of the second. Use the Out Routing Selector to choose CH1 Link (CH1 signal only) or Mix Out (mix of both channels).

What to do if the speaker does not power on?

Check that the power cable is properly connected to the MAINS INPUT and a working wall outlet. Ensure the POWER switch is in the ON position. If the issue persists, contact an authorized repairer.

How to adjust Ground Lift?

The Ground Lift selector is on the rear panel, in the Main section. In case of hum due to a ground loop, move this selector to the other position to break the ground connection.

What is the maximum height for a stand?

For the Opera 12, the maximum allowed height between the base of the speaker and the floor is 130 cm when mounted on a standard stand (35 mm pole).

Can I hang the speaker by the handles?

No, the handles are intended only for transport. It is forbidden to use the handles for hanging the speaker. Use the M10 mounting points and optional accessories (wall bracket, eyebolts) for suspended installation.

How to clean the speaker?

Dust the cabinet and grille with a soft dry cloth. Do not use liquid or abrasive products. Protect the amplifier module from moisture.

What to do if the sound is distorted?

First reduce the source volume, then adjust the gains of the CH1 and CH2 inputs. Check that cables are not damaged and that the impedance selectors (Mic/Line, Line/Instr) are correct. If the Limiter indicator remains constantly lit, reduce the level to avoid distortion.

MECHANICAL AND ACOUSTICAL FEATURES

DIMENSIONS

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)

SOUND COVERAGE

The special design of the horn, shown in the figure, 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 figure, 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.

25° -60° 85° 85° 120°

Class D digital amplifier 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 amplification power is 600 W RMS for all models.

WARNING!

• Protect the unit from moisture.
• Never attempt to disassemble the amplifier 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.
