DIGITAL SIMULATING EFFECTS
DSP is especially effective with material from CD, TV and FM radio. Just try different DSP-Modes when
using the receiver to listen to a concert or watch a sports broadcast!
Repeated use of the „DSP" (7)(48) button changes the used DSP-mode:
DSP
off
The simulation of different environments is created by adding reverberation and changing the frequency
content of the sound signal without degrading the signal quality.
The DSP mode „LIVE" creates the atmosphere of a Live-Concert at the playback of different input sources.
If the receiver input „5.1 CH INPUT" is selected, DSP programmes can not be used.
Burn in/ Warm up
Your audio components need a certain time
period until they reach maximum performance.
The duration of this „warm up" time is very diffe-
rent for the various elements of your audio system.
Higher and homogeneous sound quality is achie-
ved while keeping the device switched on.
Your audio specialist dealer has enough
experience to give you more information.
Net frequency noise
Some audio source devices may together with the
amplifier cause a humming noise at powerline fre-
quency audible from your speakers. Usually its volu-
me is variable with the volume setting of the ampli-
fier. This is no sign of a defect or fault of your audio
products but has to be eliminated.
Generally, every wall-powered device connected to
the ground wire of the power plug can cause this
problem when connected to the amplifier.

TIPS
Mostly that this problem is caused by antenna-con-
nected components (as TV-sets or Tuners), personal
computers, electrostatic loudspeakers, subwoofers,
record players or headphone amplifiers that are con-
nected to the audio inputs of the amplifier. Another
possible reason for humming noise is electromagne-
tic interference of other components' power supplies
with pick-up-systems of record players (change the
place of the record player for a test).
Some main amplifiers are equipped with a „Ground
Lift" switch. If it is activated, ground potential of the
chassis and the protective ground wire are being
separated from the central signal ground point.
The protective ground wire keeps its function.
Sometimes this helps prevent noise caused by errors
in grounding.
If the problem occurs and cannot be solved by you-
self your audio specialist dealer will help you.
