THE MAINS SWITCH IS IN THE SECONDARY POWER SUPPLY CIRCUIT.
THIS MEANS THAT THE UNIT IS NOT COMPLETELY ISOLATED FROM
MAINS WHEN THE UNIT IS IN STANBY.
About the power cord:
It is possible that in certain countries or regions, the mains plug is different to the one
supplied. In such a case a different plug can be fitted, but be careful to ensure that the
blue wire is connected to neutral, the brown to live, and the yellow/green to earth. Or
ask your dealer for a suitable power cord
Mains voltage:
Please check the mains voltage indication at the back of the unit.
For 100Vac to 120Vac, use the 115Vac setting
For 220Vac to 240Vac, use the 230Vac setting

Connection
CONNECTION
Connect the amplifier inputs to the different sources. Use good quality audio
leads. Respect the Left and Right channels. Connect the output to a suitable stereo power amplifier or two mono amplifiers (e.g. our 4020, 4040, or 2x 8010) .
Connect the power-cord to the mains connector. Check for correct mains voltage. Normally the standby/mute LED at the front will be lit (*1).
1.Auxiliary input. Connect any line level (*2) unit to this input.
2.CD input. Connect you CD player or other line level (*2) unit to this input.
3.Tuner input. Use this input to connect your tuner, or other normal line
level (*2) unit.
4.Audio/Video audio input. Use this input to connect your audio
signal coming from a VCR, DVD, MD, CDR player/recorder...

FThe +6dB function can be used to adjust the level between the different
sources. That way, when switching over between sources the volume will
approximately remain the same.
(*) When the power-cord is disconnected or after a power failure the memory will be erased.
Turning on the unit with the input selection buttons will activate a 24h auto standby timer.

Troubleshooting
TROUBLESHOOTING
Symptom
No sound coming from the speakers
+6dB memory is erased
Hum or noise is coming from the
speakers
No button is reacting anymore and/
or no LED indication is functioning
anymore
The tape recorder, MD, CDR… is
not receiving a signal
Possible cause
Mute is on, press standby/mute button. The power amplifier is turned
off.
Wrong source is selected
A power failure has occurred.
The power-cord has been disconnected.
To make sure the control amplifier is
the source of hum, disconnect all
input leads.
Use good quality audio leads.
Check the earth connection of the
phono or mains.
The control amplifier is too close to
the power amplifier or too close to
other magnetic field like a power
adapter or other mains operated
unit.
Static electricity or lightning can
cause malfunction of the unit.
Disconnect the power-cord for about
10 seconds, this will reset the internal processor.
Check the mains fuse, replace only
with indicated rating. A spare fuse is
located in the fuse holder.
The monitor function is not engaged, press the desired input once
again to engage the monitor output.
