Problem:
The machine does not respond to
remote control commands after you fit
new batteries in the remote control
handset
(only when the remote control
address has been changed using special
software).
Cause:
The remote control was set to remote
control address 2 before you changed
batteries. This setting is lost when you
change batteries.
Remedy:
Switch to remote control address 2 (see
remote control operating instructions).
Problem:
The source devices connected to the
system does not respond to remote
control commands.
Cause 1:
The unit you are trying to control is not
selected as source device, i. e. the
commands from the remote control
handset are being passed to a different
source device.
Remedy:
Press the corresponding source button on
the remote control handset and try again.
Cause 2:
The source device is not connected via an
R
LINK
cable.
Remedy:
Complete the connection as shown in the
wiring diagram.
Problem:
Loud humming noise from the
loudspeakers.
Cause:
Poor contact between the Cinch plugs
and sockets, or a faulty Cinch cable.
Remedy:
Please check all connections and cables
thoroughly.
Problem:
No output signal at the loudspeakers;
red LED on the screen flashes.
Cause 1:
The PROTECTION circuit has tripped due
to overheating or overloading.
Remedy:
Reduce volume and wait for about
20 seconds. If the unit does not switch on
again automatically, it has become too hot
and it has become too hot and should be
allowed to cool down for a few minutes.
Cause 2:
Short-circuit in the speaker leads, e. g.
stray wire ends touching at the speaker
terminals, or mechanical damage to the
cables.
Remedy:
Check speaker leads and terminals, twist
wire ends together neatly, replace
damaged cables.
Cause 3:
Overloading due to poor earth contact.
Remedy:
Disconnect input cable and wait to see if
the amplifier switches back on again; if so,
check the input lead and replace if
necessary.
Problem:
Unit switches off repeatedly at fairly
high volume levels.
Cause 1:
Overheating due to heat build-up.
Remedy:
Set up the unit in such a way that an
unobstructed flow of cooling air is
guaranteed.
Cause 2:
Overheating
through
insufficient
loudspeaker impedance.
Remedy:
Use only loudspeakers of at least 4
Ω
impedance (DIN rating). That means a
minimum impedance of > 3.2
Ω
.
Problem:
Flat sound image, insufficient bass
response.
Cause:
The loudspeaker cables are connected
with reversed polarity.
Remedy:
Check the speaker connections at the
loudspeakers and at the amplifier’s
speaker terminals; correct if necessary.
