Switching between the two power modes
HighPower / MidPower mode
The M 5.4DSP has two power modes – the “High-
Power” mode for maximum perfomance and
“MidPower” mode with reduced output power and
lower power consumption for Plug & Play applica-
tions.
Note: The “MidPower” mode is always activated
ex works.
This mode reduces the output power of the front
and rear channels to 35 Watts per channel. The
result is a lower maximum current consumption of
the M 5.4DSP and thus allows an easy Plug & Play
connection to OE sound systems with an optional-
ly available MATCH cable harnesses, e.g. PP-ISO
(see page 38).
Note:
The “MidPower” mode is not a guarantee for
a proper function in combination with the OEM har-
ness. Depending on your car it may be necessary
to connect the M 5.4DSP directly to a +12 V source.
In order to use the M 5.4DSP in “HighPower” mode
for maximum performance this has to be acti-
vated in the “Device Configuration Menu” of the
DSP PC-Tool software.
This setting may only be chosen if the power
supply of the M 5.4DSP is directly connected to
the car´s battery by using a separate cable with
sufficient cable cross-section.
Note:
The M 5.4DSP can draw currents up to 40 A
in “HighPower” mode. This may lead to an overload
of the OEM harness
(Fire hazard!)
.
Note: The activation of the “HighPower” mode
is set across all memory locations for all sound
setups. The setting can be reset at any time via
the DSP PC-Tool. After a complete reset of the
amplifier via the
Control pushbutton
, the “High-
Power” mode will also be reset.
Note:
The selected operating mode is also saved in
the “afpx” configuration files. When loading an afpx
file, this setting can be restored via the “Import ACO
Features” button.
In the following the most important steps how to ac-
tivate the “HighPower” mode are described:
1.
Connect the amplifier to your computer using
the USB cable that is included in delivery. If
you have to bridge longer distances please use
an active USB extension cable with integrated
repeater and no passive extension. Optional-
ly the connection can also be made by WIFI
CONTROL via WiFi.
2.
Turn on the amplifier and then start the soft
-
ware.
3.
Go to the “Device Configuration Menu” (DCM)
in the DSP PC-Tool software. In the “extended
features” tab you can activate and deactivate
the “HighPower” mode (see marking in the fol-
lowing image).
4.
Confirm the following warning messages to fin
-
ish the activation process.
5.
Activation is finished.
