Installation and
Operation
3.1 Branchement
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.
Balanced Wiring
1- Ground
2- Signal +
3- Signal -
Unbalanced Wiring
1- Ground
2- Signal
3- 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).

Installation and
Operation
The amplifier can operate on three different configurations: DUAL, LINK or
BRIDGE. The connections for the three
modes are different.
3.1.1 DUAL Channel Mode
3.1.1 DUAL Kanalmodus
- Switch “Off” the amp.
- Set the Mode Switch on the rear panel
to “DUAL”.
- Select the chosen Gain on the back
panel Switch (Default setting 32dB).
- Connect the signal lines to the female
XLR connectors on all channels.
- Connect the speakers’ lines to the
corresponding Speakon on the amp
respecting the polarity.
- Switch “On” the amp.
- Use the level control knob on the front
panel to adjust each channel independently.
- Each signalling LED group will show
its corresponding channel status.
3.1.2 LINK Channel Mode
3.1.2 LINK Kanalmodus
See Figure 4
3.1.3 BRIDGE Channel Mode
See Figure 5
- Switch “Off” the amp.
- Set the configuration switch on the
rear panel to “BRIDGE” (see page 9).
- Select the chosen Gain on the back
panel Switch (Default setting 32dB
+6dB).
- Connect a signal line to input female
XLR Channel “A” (or Ch-C in 4 channel models).
- Connect the speaker line to the
Channel A Speakon (or Ch-C in 4
channel models) wired to +1 and +2.
In this way pin +1 is positive.
WARNING! S6000, S6004 and S6044
models in BRIDGE mode, have a particular connection: the speaker has to
be wired to pin +1 and -2 (pin +1 is
positive). The “-“ pins in these
models, do not have to be Ground!
- Switch “On” the amp.
- Use Channel-A (or Ch-C in 4 channel
modes) control knob to adjust the
amp’s output.
- The signalling LED groups will show
the single channel status.

Installation and
Operation
3.2 Configuration
3.2 Konfiguration
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 Troubleshooting
In the event of incorrect connection or
misfunctioning, the amp will activate
one or more of its LED to warn about
the problem.

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

Protection Systems
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.
ICL2™ - Intelligent Clip Limiter
The RAM Audio 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.
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.
