ume of you car radio to minimum position during
first start-up. Additionally no device should be con
-
nected to the
Line Out
until general settings in the
DSP PC-Tool software have been made. Especially
if the M 5DSP MK2 will be used to drive fully active
speaker systems, a wrong setup can destroy your
tweeters right away.

Control pushbutton
The M 5DSP MK2 provides 10 internal memory lo
-
cations for sound setups. The
Control pushbutton
allows the user to switch between two memory po-
sitions. These can be defined in the DSP PC-Tool.
Note:
The memory locations one and two are de-
fined ex works.
To manually switch between the setups the button
has to be pressed and held for one second. Switch-
ing is indicated by a single red flash of the
Status
LED
. To switch between all internal memory loca-
tions, the optionally available DIRECTOR display
remote control or the WIFI CONTROL is recom
-
mended.
Pressing the button for five seconds completely
erases the internal memory. This is indicated by a
continuous red glowing and constant green flashing
of the
Status LED
.
Attention:
After erasing the setups from memory
the MATCH M 5DSP MK2 will not reproduce any
audio output.

Remote In / Out
Remote In: The remote input has to be used to turn
on / off the M 5DSP MK2 if the signal source which
is connected to the highlevel inputs is not activating
the “automatic turn-on” function or if the amplifier
shall only
be activated / deactivated by a remote
signal applied to the
Remote In
input.
Remote Out: We strongly recommend to use the
remote output for turning on / off additional am
-
plifiers that are connected to the
Line Out
of the
M 5DSP MK2. This is essential to avoid any unde
-
sired pop noises during DSP boot or software up-
date process. Additionally this output will be turned
off during the “Power Save Mode” or a software up
-
date process.

Status LED
The
Status LED
indicates the operating mode of the
amplifier and of the DSP memory.
Green:
Amplifier is ready for operation.
Orange:
Power Save Mode is active.
Red:
Protection Mode is active. This may have dif
-
ferent root causes. The MATCH M 5DSP MK2 is
equipped with protection circuits against over- and
undervoltage as well as overheating. Please check
for connecting failures such as short-circuits or oth-
er wrong connections.
If the amplifier is overheated the internal tempera
-
ture protection switches off the remote and signal
output until it reaches a safe temperature level
again.

Optical Input
Optical input in SPDIF format for connecting signal
sources with a digital audio output. The sampling
rate of this input must be between 12 and 96 kHz.
The input signal is automatically adjusted to the in-
ternal sample rate. In order to control the volume of
this input, we recommend to use an optional remote
control or the WIFI CONTROL.
Notice:
This amplifier can only handle stereo input
signals and no MP3- or Dolby-coded digital audio
stream!
10
Control Input
This multi-functional connector is designed for
MATCH accessory products like a remote control
which allows to adjust several features of the am
-
plifier. Depending on the type of remote control, the
functionality at first has to be defined in the “Device
Configuration Menu” of the DSP PC-Tool software
or on the remote control itself.
