MONO POWER CONFIGURATION
(warning, unsuitable for subwoofer use)
For mono power use, we have equipped our amp modules with an internal switch (15) that can bypass all filtering and
protection stages. Note that the connected speakers won’t be protected against a potential overpower anymore
(risks
of mechanical/thermal breakdown, see exclusions of warranty).
Set the volume (9) with great care. The settings (6), (7),
(8), (12), (13), and (14) are disabled when using this configuration. Only the volume knob (9) remains active. This
configuration is appropriate for specific uses of our modules only, such as broadband use or in the manufacture of
powered monitors.
FACTORY SETTINGS:
Reminder
: The “factory settings” switches (12), (13), (14) have positions that are specific to each individual subwoofer model and must never be
modified by user (risk of damaging the loudspeaker, resulting in immediate cancellation of warranty).
EQ (12)
Linear Mode:
Designed for vented box
(ex : Rafale V38 “S“, Rafale VR series)
Closed Mode:
Designed for sealed box
(ex : Furtive Sub, Eurus SWB-X)
X-MAX (13)
X-GUARD 2 Positon:
Maximum protection
X-GUARD 1 Position:
Intermediate protection (s250 module, or specific uses of s500 module)
OFF :
No mechanical protection
WARNING: For specific uses only, do not employ this setting for any factory model or Atohm subwoofer kit (may
result in loudspeaker mechanical breakdown, see exclusions of warranty).
Max Rms Voltage curves at amplifier output with « X35 » setup ( « X30 » setup is shifting by 5hz all the curves to low frequencies )
U-MAX (14)
0dB Position:
Nominal voltage limit (maximum voltage: 27.5Vrms/s250 and 42.5Vrms/s500)
-1dB Position:
-1dB voltage limit (maximum voltage: 24.5Vrms/s250 and 37.8Vrms/s500)
–1dB mode may be used as an additional protection of the X-GUARD 2 protection for loudspeakers that cannot
handle high power.
REVISION S250 VERSION X - NOV 2019
The X-GUARD PCB is including 2 setup : X-35 ( exactly the same adjustment than X GUARD version 1) and X-30 ( lowering by 5 Hz of the X-
GUARD adjustment ) . Amplifier module comes with X-30 setting when it is sold as stand alone unit.
XG-35 SETUP = RAFALE V38S – V35 -FURTIVE SUB
XG-30 SETUP = RAFALE VR1-X , SL1-X et EURUS SWB-X
REVISION S500 VERSION X - NOV 2020
The X-GUARD PCB is including 2 setup : X-35 ( exactly the same adjustment than X
GUARD version 1) and X-30 ( lowering by 5 Hz of the X-GUARD adjustment ) .
Amplifier module comes with X-30 setting when it is sold as stand alone unit.
X-35 SETUP = KIT RAFALE VR2 / VR3
X-30 SETUP = KIT RAFALE VR2-X / VR3-X
S500 X with « SL3M-X » pcb ( this version is not sold as stand alone unit)
X-35 SETUP : GT-SW2 / EURUS SW / RAFALE SL3M
X-30 SETUP : GT-SW2-HD / EURUS SW-X / RAFALE SL3M-X
