Controls and connections are the same for the three models.
1
The W28As, W24As and W22As speaker systems are equipped
with XLR male (OUT) and female (IN) parallel connected sockets
allowing easier daisy-chaining.
Mixer output
Input ('IN' socket) of the speaker system
Output ('OUT' socket) of the speaker system
Input ('IN' socket) of
the speaker system to be connected in parallel.

2
Main volume (VOL). Adjusts the input levels of the two built-in
ìpower amplifiers to adapt them to the output level of the mixer.
3
High frequencies level control (H.F.).
Note
: if you are using a Montarbo mixer (or any mixer having an
output level of 0dB) for optimum performance it is advisable to set
both controls fully clockwise (to their maximum settings).
4
POWER / 0 - I: Mains power on/off switch.
5
Fuse holder with built-in fuse.
6
Mains supply inlet socket with type A PowerCon® (blue) connector,
which guarantees a reliable, vibration-proof contact. Use only a mains
cable with suitable conductors capable of handling the current involved,
equipped with a ground conductor, marked with the applicable, country
specific, safety approvals and fitted with a power plug certified for the
actual current value. Refer to page 14 for connector wiring instructions.
When installing make sure that it is easy to get to this socket and to the
mains plug.
7
Power 'LINK' socket (type B gray PowerCon® connector) that allows
you to link other devices to the mains power (max. current available:
13.7 A).
CAUTION
The power supply PowerCon® socket (6) is rated for a 20 A maximum
current. The maximum current that may be sourced from the 'LINK'
socket is 13.7 A.
If the 'LINK' (7) socket is used to supply power to other devices,
it is the user's responsibility to verify that:
- this maximum current drain is not exceeded,
- the complete electrical circuit (master wiring cabinet, mains
supply socket, plug and cable) are of suitable specifications.
If in doubt, refer to a qualified technician
Example:
Three model W28As speakers have a maximum current drain of about
19 A (6.3 A x 3) > OK (19 A < 20 A).
Four model W28As speakers have a maximum current drain of about
25 A (6.3 A x 4) > NOT OK!
In this case you must use two independent power supply cables.
(two lines, each powering two W28As).
8
The output stages are cooled by a forced air heat exchanger,
equipped with a temperature-controlled, low-noise fan.
Note
: in order to reduce noise and dust build-up, the thermostatically
controlled fan is not activated unless the amplifier heats up to a pre-set
level, and it turns off automatically when the temperature drops back
down below this level.
