How to use

Place the OPERA 10 on a stable surface or mount it on a suitable speaker stand. Connect source devices such as mixers, instruments or playback devices to the speaker's input connectors using appropriate cables. Power the speaker from a compatible mains supply and set input gain and output levels to match the venue and source signal. Position the speaker to aim sound toward the audience while avoiding pointing directly at reflective surfaces to reduce unwanted reflections.

Recommendations

For reliable performance, allow the amplifier to cool between extended high-power sessions and secure the speaker during transport. Use a dedicated speaker stand for optimum dispersion and elevation. When combining multiple units, align levels and use basic equalization to avoid frequency overlap and to achieve coherent coverage across the listening area.
