Don’t attempt to open or to repair this unit by yourself. For any problem solution not described
in this owner’s manual, please refer to qualified personnel only or consult us or your National
Distributor. Any improper operation could result in fire or electric shock.
Damages requiring services:
• Don’t attempt to do operations not described in this user’s manual.
• In the following cases please refer to an authorized maintenance center or skilled
personnel:
- When the unit works improperly or it doesn’t work at all.
- If power cord or plug are damaged.
- If liquid has spilled, or objects have fallen into the unit.
- The unit has been exposed to rain.
- The unit doesn’t operate normally o it exhibits a marked change in performance.
- If the product has dropped or it has been damaged in any way.
Maintenance:
The user shouldn’t attempt maintenance operation not described in this user’s manual. Every
maintenance operation should be done by qualified personnel only.
IMPORTANT SAFETY INSTRUCTIONS:
• Install this unit following owner’s manual instructions.
• Don’t install, connect or disconnect power supply when the unit is powered, otherwise
there’s an high risk of electric shock.
• Don’t open the unit, there are no user serviceable parts inside.
• If you detect a particular smell from the unit, please turn it off immediately and disconnect
the AC power cord.
• Don’t block the unit ventilation openings.
• Avoid using this unit in overload for a long period.
• Don’t force commands (switches, controls, etc.)
• To obtain good speakers wire contacts, please tighten the screw terminals firmly.
• For safety reason, don’t defeat the grounding connection. Grounding is useful for user
safety.
• Use only connectors and accessories suggested by the manufacturer. .
• This unit should be placed in a rack (see INSTALLATION) and kept far from:
Wet places
Direct exposure to heat sources (like sun light)
Non properly ventilated places
• Disconnect the power cord during storms or when the unit is not used.
• In order to prevent fire and electric shock risks, it’s necessary to keep the unit far
from sprinkling and drops. Please don’t put cups, vases or other object containing liquids
over the unit. In case of interferences from source signal, THD value will raise over 10%.
Don’t place this unit in a bookshelf o in other places with small room.

DESCRIPTION
APW series amplifier has been specifically designed for paging, music, and
sound reinforcement applications in P.A. systems.
FEATURES:
• Balanced XLR inputs.
• Balanced 6.3mm (1/4”) jack inputs.
• Three Speak-on discrete output connectors for CHANNEL A,
CHANNEL B and BRIDGED mono speaker.
• Output signal (SIG) LED indicator.
• Output overload (OL) LED indicator.
• 30Hz subsonic filter to avoid speaker damage by unwanted and
dangerous subsonic frequencies.
• CLIP LIMIT switch to allow output signal limiting to protect
loudspeakers from the effects of clipping.
• AMP MODE three way selector to choose amplifier operating
mode among MONO, STEREO and BRIDGED. In STEREO mode
the amps works in a “standard” way with both levels and both
outputs working. In MONO mode only Left channel input level
works, setting the levels for both amp Speak-on outputs
(CHANNEL A & CHANNEL B). In BRIDGED mode only Left
channel input level works, setting the level for BRIDGED Speak-on
output.
• Three Speak-on output connectors for professional and reliable
amplifier to speaker connection, named CHANNEL A, CHANNEL
A, and BRIDGED. Please note that BRIDGED output must be used
with AMP MODE BRIDGED selection only, while CHANNEL A and
CHANNEL B outputs should be used both in MONO mode both
STEREO mode.
• In order to reset the amp operation in case of uneven operation
there’s a resettable BREAKER circuit. If this circuit breaks
continuously there’s a serious problem, like speaker real load
impedance lower than 2-Ohm in mono or stereo or lower than 4-
Ohm in bridge, or the circuit is detecting an amplifier malfunction.
FRONT PANEL DESCRIPTION
fig.1
1) Power switch and power LED.
2) A & B level controls.
3) SIG LED (Signal LED) – these LEDs indicate that a signal is present
after the level controls.
4) OL LED (Overload LED) – these LEDs turn on when the output of
the amplifier reaches its maximum. It’s OK if this LED blinks
occasionally, but if it blinks continuously or frequently, please turn
down the source signal or the level controls.
REAR PANEL DESCRIPTION
fig.2
1) XLR & 6.3mm. (1/4” TRS) jack, balanced linked inputs.
2) 30Hz sub-sonic filter.
3) CLIP LIMITER circuit on/off switch.
4) AMP MODE selector:
MONO – Input A only is active and its signal is routed to both
amplifier stages. The level control of channel A sets the output
level for CHANNEL A & CHANNEL B Speakon outputs.
STEREO - Two independent amplification paths, input A is output
on CHANNEL A Speakon, while input B is output on CHANNEL B
Speakon.
BRIDGED - Input A only is active and its signal is routed to both
amplifier stages, linked in a “bridged” way (in order to supply more
power, the powered signal of both amplification section is
summed). The level control of channel A sets the output level for
BRIDGED Speakon output.
5) Three Speak-on output connectors for CHANNEL A, CHANNEL B
and BRIDGED. Please note that BRIDGED output must be used with
AMP MODE BRIDGED selection only, while CHANNEL A and
CHANNEL B outputs should be used both in MONO mode both
STEREO mode.
6) BREAKER circuit reset switch is available only in the 220VAC
version.
115 VAC version traditional fuse.
7) Mains AC IEC standard power input.
