INDEX
- Electrical appliance.
The exclamation mark within a triangle identifies the presence of electricity. Use the system carefully
without wet hands or feet. Avoid installing the speaker in wet or excesivelly humid places. Regularly
check the condition of the cables and make sure these are not being walked on or pinched. Connect
the speaker to bipolar, earthed mains. The mains plug must be connected to the appropriate protection
(fuse or breaker). Connection to any other type of mains could result in an electrical shock and violate
local electrical codes. DO NOT CONNECT OR DISCONNECTTHEAC POWER CONNECTORS UNDER
LOAD.
- Electrical shock risk.
The diagonal mark within a triangle identifies the presence of dangerous voltage. Do not open or handle
the interior of the amplifier. These parts are not to be adjusted by the user. For maintenance and/or
repair please go to an authorized service centre. In order to reduce the risk of electric shock, disconnect
from AC before plug in or unpluggingAudio signal cables. Reconnect toAC only if all signal connections
are made and secured. Never manipulate the ground type plug provided. The AC mains plugs should
always remain accessible for operation. Unplug the amplifier during storms or when it’s being used for
a long time.
- Delicate Material.
Please ensure no foreign object or water enters the amplifier. Do not place material that contains liquid
on or near the unit. Only clean the unit with dry cloths. Do not use solvents.

3. Installation and Operation
3.1 Connections
The Power switch must always be on the .Off. position before plugging the amp to a properly earthed mains socket (220-
240V AC / 110V-120V AC).
The input signal fed to the amplifier can be either balanced or un-balanced. The drawing below describes both ways to
wire an XLR connector for the purpose.
Balanced Signal: Connect pin 1 to Ground, pin 2 to Signal + (hot) and pin 3 to Signal - (cold).
Unbalanced Signal: Connect Pin 1 to Ground, pin 2 to Signal and pin 3 to Ground.
Important!:
If a connection is done with a un-balanced line and pin 3 on the XLR is not connected to ground, a 6 dB loss occurs in the
line and only a quarter of the amplifier power is produced.
The two channel amplifier models provides, for each channel, a female XLR Connector (Signal Input) parallelled to a male
XLR to daisy chain several amplifiers with the same signal line (LINK).

3.2 Configuration
The amplifier has an ensemble of minidips on the back panel, which allow for the following configurations: the
highpass subsonic filter, the ICL deactivation and the bridge mode. All these configurations can be cross-set in any
way, independently from the others. The basic configuration possibilities are as follows:
Standard Configuration: the amplifier works without high pass subsonic filter, Clip Limiter ICL enabled and no
Bridge mode.
Sub-sonic Filter Enabled: the amplifier works with high pass subsonic filter (30Hz in this case), Clip Limiter ICL
enabled and no Bridge mode.
Bridge Mode: the amplifier works without high pass subsonic filter, Clip Limiter ICL enabled and Bridge mode.
ICL Clip Limiter Disabled: the amplifier works without high pass subsonic filter, Clip Limiter ICL disabled and no
Bridge mode.

3.3 Protection Systems
ICL2™. - Intelligent Clip Limiter
The ICL2 is an anticlip system to avoid speaker failure and provide more acceptable sound quality even when
clipping occurs. With the ICL2 system you don’t lose the music .punch. but the speakers are kept under
control.
PMS™. - Power Management System
This is a complete set of protections that monitors the main amp parameters (load status, signal input,
temperature, current, etc.) in order to draw from the power supply only the precise amount of current required
to maintain safe operation during hazardous or extreme working conditions.
This system controls the amount of power that the amp delivers under three basic circumstances:
1.- The power-on sequence, where output is inhibited until the amp circuits are ready to operate. This routine
is repeated at every restart, not just when the power switch is activated.
2.- When internal temperatures rise to near thermal shutdown point due to unfavourable operating conditions.
Here the system takes control, restricting current so as to maintain operational continuity at the precise power
level which the amp is capable of withstanding at that particular moment.
3.- Excessive mains current consumption. This event only occurs either under laboratory conditions (long term
sinusoidal signal testing with dummy loads) or, for example, in field applications in conditions of prolonged
acoustic howl-round. Here PMS takes control to avoid any damage to the speakers and to prevent the mains
breaker from tripping or the fuses blowing.
SSP™. - SOA Sentry Protection
SOA Sentry protection effectively limiting the power that the amp could deliver into an incorrect load or to a
direct short-circuit. This avoids power transistor failure.
WARNING:
The exclamation point inside an equilateral triangle indicates the existence of internal components whose
substitution may affect safety.
The lightning and arrowhead symbol warns about the presence of uninsulated dangerous voltage.

To avoid fire or electrocution risk do not expose the unit to rain or moisture. To avoid electric shock, do not open
the unit. No user serviciable parts inside. In the case of disfunction, have the unit checked by qualified agents.
Class I device.
CAUTION
RISK OF ELECTRIC SHOCK
DO NOT OPEN
3.4 Troubleshooting
In the event of incorrect connection or misfunctioning, the amp will activate one or more of its LED to warn about
the problem.
Correct function: SGNL lights to indicate signal presence.
ICL: The Intelligent Clip Limiter is operating.
No Signal: No Input Signal is reaching
the amp.
Overheating: The amplifier has reached the maximum operational temperature. Most common cause is: the normal
air flow is blocked, accumulated dirt, dust or object leaning against the grill. Check and clean periodically.
PMS: Several causes can trigger this LED, most common are:
- The amplifier is in power-on sequence, where output is inhibited until the amp circuits are ready to operate.
- The internal temperatures rise to near thermal shutdown point due to unfavourable operating conditions.
- Excessive mains current consumption.
