puts at the same time.
Important:
The signal of a digital audio source
normally does not contain any information about
the volume level. Keep in mind that this will
lead to full level on the outputs of the MATCH
UP 7DSP. This may cause severe damage to
your speakers. We strongly recommend to use
an optional remote control for adjusting the vol-
ume level of the digital signal input!
Information:
The UP 7DSP can only handle
uncompressed digital stereo signals in PCM
format with a sample rate between 12 kHz and
96 kHz and no MP3- or Dolby-coded digital au-
dio stream!
5. Connection to power supply
Make sure to disconnect the battery before
installing the MATCH UP 7DSP!
Connect the +12 V power cable to the positive
terminal of the battery. The positive wire from
the battery to the amplifier power terminals
needs to have an inline fuse (50 A) at a distance
of less than 12 inches (30 cm) from the battery.
If your power wires are short (less than 1 m /
40”) then a wire gauge of 6 mm² / AWG 10 will
be sufficient. In all other cases we strongly rec
-
ommend gauges of 10 - 16 mm² / AWG 8 – 6!
The ground cable (same gauge as the +12 V
wire) should be connected to a common ground
reference point (this is located where the neg-
ative terminal of the battery is grounded to the
metal body of the vehicle) or to a prepared met-
al location on the vehicle chassis, i.e. an area
which has been cleaned of all paint residues.
6. Connecting the remote input
The remote input has to be connected to the
radio remote output if the amplifiers
Optical In-
put
is solely used as signal input. We do not
recommend controlling the remote input via the
ignition switch to avoid pop noise during turn
on / off.
If the highlevel inputs of the
System Connec-
tor 1
are used this input does not need to be
connected as long as the car radio has BTL
output stages.
7. Configuration of the remote input
The UP 7DSP will be turned on automatically if
the highlevel inputs of the
System Connector 1
are used or if a remote signal is applied to the
remote input (
REM
) terminal. The
Auto Remote
switch (page 19, item 1) allows to deactivate
the automatic turn-on feature of the highlevel
inputs of the
System Connector 1
. The feature
should be deactivated if there are e.g. disturb-
ing noises while switching on / off the amplifier.
Note:
If the automatic turn-on function is de-
activated it is mandatory to use the remote
input terminal to power up the amplifier! The
highlevel signal of the
System Connector 1
will
be ignored in this case.
To deactivate the automatic turn-on feature you
have to change the position of the
Auto Remote
switch to “Off”.
8. Configuration of the internal DSP
The general amplifier settings should be
conducted with the DSP PC-Tool software
before using the amplifier for the first time.
Ignoring this advice may result in damaging the
connected speakers / amplifiers. Especially if
the UP 7DSP will be used to drive fully active
speaker systems, a wrong setup can destroy
your tweeters right away.
Information on connecting the UP 7DSP to a
computer can be found on page 27.
9. Connecting the remote output
This output (
Remote Out
) is used to supply re-
mote signals to additional amplifiers that are
connected to the
Line Out
of the UP 7DSP. Al-
ways use this remote output signal to turn on
the amplifiers in order to avoid on / off switching
noises.
