I/O AND CONTROL OPERATIONS
MAINS~ IN -
Powercon® �AC3PX power inlet connector. ��o switch the amplifier on, insert
Powercon® �AC3PX power inlet connector. ��o switch the amplifier on, insert
the Powercon® connector and turn it clockwise into the O� position. ��o switch the amplifier
off, pull back the switch on the connector and turn it counter-clockwise into the POW���
OFF position.
MAINS~ OUT -
Powercon® �AC3PX power outlet connector. ��his is connected in parallel
Powercon® �AC3PX power outlet connector. ��his is connected in parallel
with the MAI�S~ I�.
WARNING! Connect no more than one subwoofer unit to the MAINS~ OUT
connector.
WARNING! If you use the MAINS~ OUT turn on each subwoofer unit one a time.
WARNING! In the case of product failure or fuse replacement, disconnect the unit
completely from the mains power.
WARNING! Use a suitable power cable and mains plug to build the power cable, it
must only be connected to a socket corresponding to the specifications indicated
on the amplifier unit.

ON
- ��his L��D indicates power on status.
PROT
- ��his red L��D lights when the amplifier module is in protect mode for an internal fault
and, consequently, the amplifier is muted.
SIGN LIMIT
- ��his L��D lights in green to indicate the presence of the signal and lights in red
when an internal limiter reduces the input level.
INPUT
- Audio signal input with locking XL� connector. It has a fully electronically balanced
circuitry including AD conversion for the best S��� ratio and input headroom.
LINK
- A direct connection from the input connector to
link other speakers with same audio signal.
GND LIFT
- ��his switch lift the ground of the balanced
audio inputs from the earth-ground of the amplifier
module.
PRESET BUTTON
- ��his button has two function:
1)
Pressing it while powering on the unit:
ID ASSIGN
the internal DSP assigns a new ID to the unit
for the P�O����� remote control operation.
��ach loudspeaker must have a unique ID to
be visible in the P�O����� network. When you
assign a new ID, all the other loudspeakers
with the ID already assigned must be O� and
connected to the network.
2)
Pressing it with the unit O� you can select the
DSP P���S����. ��he selected P���S���� is indicated by the
corresponding L��D:
STANDARD
��his P���S���� is suitable for any application
where low frequency reinforcement is
required. It features a ���H�� cut off frequency
and it can be used in almost any environment
in combination with any vertical arrays.
INFRA
��his P���S���� can be used when a deeper bass
response is required (�ote that when this preset is used the sound pressure level of the system is slightly reduced). �O����: I�F�A and
S��A�DA�D P���S���� must �O�� be used together in close units.
CARDIOID
��his special P���S����, combined with the S��A�DA�D P���S����, gives the advantage to reduce the low frequencies at the back of an array
of three subs, in order to obtain a more comfortable level for the performers on the stage without losing level for the the audience in
front of the array. ��he cardioid configuration is also useful in situation where you want to reduce the bass frequency feedback due to
many microphones on stage, for example for acoustic and ja���� ensemble, classic orchestra, musicals. Further in this manual you can
find some example how to set up a cardioid array.
USER
��his L��D lights when the US��� P���S���� is loaded. ��his preset corresponds to US��� M��MO�Y no. 1 of the DSP and, as a factory setting,
it’s the same to S��A�DA�D. If you want to modify it, you have to connect the unit to a PC, edit the parameters with P�O����� software
and save the P���S���� into US��� M��MO�Y no. 1.
NETWORK IN/OUT
- ��hese are a standard �J�5 CA��5 connectors (with optional ���U���I� ���8MC �J�5 cable connector carrier), used for P�O�����
network transmission of remote control data over long distance or multiple unit applications.
TERMINATE -
In a P�O����� network the last loudspeaker device must be terminated (with an inner load resistance) especially in a long run cabling:
press this switch if you want to terminate the unit.
