CONTROLS AND FUNCTIONS
ON: Indicates that the system is on.
PEAK/LIMIT: When the “peak” LED goes on, it indicates that the signal level is nearing saturation; the “limit” LED indicates that the temperature limiting
circuits have triggered to prevent the system from overheating.
TILT NOT ALLOWED: indicates a “pointing” error; check the maximum allowed tilt of the sound band in the “allowed angle settings” table.
NETWORK ON: signals that connection to the network has been enabled.
TILT ANGLE: allows you to set the tilt angle of the sound beam. Negative angles conventionally refer to a sound beam tilted toward the lower part of the
speaker; the maximum tilt limits of the sound beam associated to the covering angle are shown in the relevant table. If these values are exceeded, a pointing
error will be signaled by the “TILT NOT ALLOWED” LED going on. The PC/SLAVE position brings the loudspeaker in data receiving mode, with the option of
controlling it via the second speaker connected to it or via the relevant software on the PC.
BEAMWIDTH: allows you to select the opening angle of the sound beam; follow the limits listed in the table to properly program the system.
VOLUME: Adjusts the volume of the single loudspeaker.
PRESET: Selects 4 presets, each corresponding to a different equalization, based on the installation to be performed (FOH for installations in open field or
WALL for fixed installations) and the use made of the system (FLAT for music or VOCAL for speech).
RESET: allows you to reset the internal memory that contains the data sent by the PC in a setup possibly configured previously. If performed in “stand-alone”
mode with connected speakers, the reset control is also transmitted to the MLA 608A loudspeaker. We recommend that you perform a reset (pressing the
relevant key or with the software) when shifting from using the system connected to the PC to “stand-alone” mode, so as to eliminate the possibility of any
malfunctions.
GND LIFT: electrical switch for the electrical separation between the mass and ground circuits, in order to avoid possible mass “loops”, which are the source
of bothersome humming sound.
IN - LINK: Balanced input/output sockets; “IN” allows the connection of pre-amplified signal, such as for instance the one in output from a mixer. “LINK” allows
you to connect multiple loudspeakers to the same signal. USE “EUROBLOCK” SOCKETS FOR WALL CONNECTIONS.
IN-NETWORK-OUT: see the description in the "CONNECTION OF LOUDSPEAKERS" section.
