6.OVERVOLTAGE PROTECTION

The Xcellence series models incorporate protection against mains voltage overload.
In the mains input an electronic circuit compares the actual voltage with a reference
value. When the input tension exceeds 250 Volts, the circuit reacts by blocking the
input tension until it returns to its correct limits (230V +/- 10%).
When the overvoltage LED lights up red, the unit stops running, until the correct
voltage is re-established.
Generally the cause of such an anomaly tends to be a neutral voltage drop or
incorrect connection of the equipment to 400V supply. Whenever the overvoltage
LED lights up, check the tension of the electrical phases: other devices in the sound
system are also at risk of electrical fault.

7.MOUNTING AND INSTALLATION

Whenever possible, mount the Full Range units in a high position (between 2 and 3
meters above ground), angled towards the audience. If the units are mounted close to
the ground the back row listeners will receive low quality sound.
Due to the coaxial technology design the cabinets must be oriented so that the
central angle axis (0º) is directly focused at the rear part of the audience. Thus all the
high frequency energy is directed towards the furthest spectators; those the front
rows will receive high frequencies generated beyond the acoustic axis, with a more
acute yet balanced, equalized level in respect to the back rows.
