Trouble shooting
Many problems have a simple cause
which is simple to put right. In this section
we list a number of possible problems
together with the method of eliminating
them. If you meet a problem which cannot
be sorted out using these notes, then
please contact an authorised
service
workshop without delay.
Problem:
'
Flat
'
sound image, in-
adequate bass response.
Cause:
The speaker leads are not
connected
'
in phase
'
.
Remedy:
Check
the
connections
between the speaker leads,
the
speakers
and
the
amplifier speaker terminals,
referring
to
the
wiring
diagram, and correct where
necessary.
Problem:
Bass too powerful.
Cause:
The speaker is located too
close to the wall or in a
room corner.
Remedy:
Keep the speakers at least
50 cm away from the side
walls, or alter the setting of
the
'
Bass
'
switch on the
rear of the speaker (TAL
series).
Problem:
No output signal at the
loudspeakers.
Cause 1:
The amplifier's Protection
circuit has tripped due to
overheating or overloading
.
Remedy:
Reduce volume; if the
amplifier does not switch
itself on again after about
20 seconds, then it has
become too hot. Leave it
switched off for a few
minutes to cool down.
Cause 2:
Short-circuit in the speaker
leads; e. g. by stray cable
'
whiskers
'
at the terminal
clamps,
or
due
to
mechanical damage to the
cable.
Remedy:
Check the speaker leads
and terminal clamps. Twist
wire ends together tightly,
or fit cable end sleeves.
Replace defective cables.
