Alternatively, it's possible to install the speaker in a less protruding way by using the other two inner holes on the U bracket. Before tightening the two M10 bolts, adjust the loudspeaker vertical tilt and then (when you found the right angle) fix it through two M4.2x22 self-threading screws (passing through the small hole of the U bracket) directly into the loudspeaker cabinet wood.

NOTE: instead of simple M10 bolts, it is possible to use the M10 bolt included knobs.

CAUTION: do not tilt the loudspeaker upwards.

6. VERTICAL MOUNTING WITH U BRACKET

Accessories needed:

• V-BR 2X COMPACT M 12 (for COMPACT C 32);
• V-BR 2X COMPACT C 45 (for COMPACT C 45);

Fix the U bracket to the wall / ceiling through at least 4 lateral wall plugs (max. M8) plus a central one (max. M10).

1. After removing the screws on the speaker sides, fix the angular adaptor on the speaker with the M8x45 screws.
2. Place the plastic cover on the angular adaptor.
3. Fix the braket to the speaker with the M10x30 screws placing a grower washer between the bracket and the plastic cover.

Set the speaker vertical tilt and fix the inclination by screwing the two M6 screws on the adaptor.

NOTE: alternatively, a less protruding installation is possible thanks to the inner holes of the U bracket.

CAUTION: do not tilt the loudspeaker upwards.

HORIZONTAL CONFIGURATION (horn rotated)

WARNING! CAUTION!

• The total loudspeaker impedance must not be lower than the amplifier output impedance. Note: a loudspeaker total impedance equal to the amplifier output one permits to get the maximum deliverable power (but an higher loudspeaker impedance entails less power).
• The total loudspeaker power shall be adequate for the maximum deliverable power of the amplifier.
• The loudspeaker line shall be short (for long distances, it may be necessary to use cables with large cross-section wires).
• Always use cables having wires with an adequate cross-section, considering the cable length and the total loudspeaker power.
• Loudspeaker lines must be kept separated from the mains cables, microphone cables or others, in order to avoid inductive phenomena may cause hum or noises.
• Use loudspeaker cables with twisted wires to reduce hum caused by inductive effects due to coupling with electromagnetic fields.
• Do NOT connect the low impedance input directly to 70 / 100 V constant voltage lines.
