POWER INPUT
MAINS~ IN -
Powercon® NAC3PX power inlet connector. To switch the amplifier on, insert
the Powercon® connector and turn it clockwise into the ON position. To switch the amplifier
off, pull back the switch on the connector and turn it counter-clockwise into the POWER
OFF position.
MAINS~ OUT -
Powercon® NAC3PX power outlet connector. This is connected in parallel
with the MAINS~ IN.
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.

CONTROL PANEL
ON -
This LED indicates power on status.
PROT -
This red LED lights when the amplifier module is in protect mode for an internal fault
and, consequently, the amplifier is muted.
SIGN LIMIT -
This LED 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 XLR connector. It has a fully electronically balanced
circuitry including AD conversion for the best S/N ratio
and input headroom.
LINK -
A direct connection from the input connector to
link other speakers with same audio signal.
GND LIFT -
This switch lift the ground of the balanced
audio inputs from the earth-ground of the amplifier
module.
PRESET BUTTON -
This 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 PRONET
remote control operation. Each
loudspeaker must have a unique
ID to be visible in the PRONET
network. When you assign a new
ID, all the other loudspeakers with
the ID already assigned must be ON
and connected to the network.
2)
Pressing it with the unit ON you can select the
DSP PRESET. The selected PRESET is indicated by
the corresponding LED:
STANDARD
This PRESET is suitable for any
application where low frequency
reinforcement is required. It
features a 90Hz cut off frequency
and it can be used in almost any
environment in combination with
any vertical arrays.
INFRA
This PRESET can be used when a
deeper bass response is required
(Note that when this preset is
used the sound pressure level of
the system is slightly reduced).
NOTE:
INFRA and STANDARD
PRESET must NOT be used
together in close units.
CARDIOID
This special PRESET, combined
with the STANDARD PRESET, gives
the advantage to reduce the low
frequencies at the back of an
array of three subs, in order to
