Possible Cause
Mains cable is not connected to a suitable
mains wall outlet.
Mains cable has not been firmly inserted into
wall power socket and the device's socket
(8). Otherwise it may be defective.
Unit fuse or unit is defective.
A device connected to the "POWER CON-
TROL" input (6) transmits the switching signal
(12V).
The audio source currently selected at the pream-
plifier is giving no signal.
The output of the source device is not connected
or is wrongly connected e.g. not connected to the
selected input channel terminal of the preamplifier.
Wrong input channel has been selected at the pre-
amplifier.
Volume setting of the preamplifier is set too low.
The preamplifier has been muted (MUTE-Function).
Output of the preamplifier not connected or incorrect-
ly connected to the input connectors of the SP-994.
The setting of the toggle switch "XLR/RCA" (4) on
the front panel is not correct.
The speaker cable is not properly connected to the
main amplifier's terminals (5) or is defective.
The cable connections are not tight, the con-
nectors are dirty or a cable is defective.
A record player has been connected to a line
level input of the preamplifier without using a
phono preamplifier.
An audio source with standard line level out-
put (example: CD player) is connected to the
main amplifier direct "INPUT" (7).
Countermeasure
Connect to a functioning socket using a suit-
able mains voltage.
Check the power cable. If necessary,
exchange it with a suitable mains cable and
push its plug firmly into wall socket and the
device's power connector.
Contact your dealer.
Switch off the device that controls the swit-
ching on/off of the system (usually preampli-
fier or integrated amplifier). If the power con-
trol function is not desired, remove all the
cables from the "POWER CONTROL" con-
nectors.
Switch on the source unit and begin play-
back.
Correct the connection.
Set the preamplifier to the input that your
desired source is connected to.
Carefully increase the volume of the pream-
plifier.
Deactivate the MUTE function at the pream-
plifier after, as a precaution, reducing the
volume level.
Correct the connection to the preamplifier.
Reduce the volume setting of the preamplifier
and set the selector to the correct input.
Check and tighten the speaker cables at the
main amplifier (5) and at the speakers.
Check the cables and cable connections.
Interconnect a phono preamplifier.
Do not connect line level audio sources at the
main amplifier inputs.
