ADVANTAGE

Thank you for purchasing the ADVANTAGE S-250 Power-
amplifier.
Your S-250 is a state-of-the-art unit, and has been assembled
by highly skilled ADVANTAGE craftsmen to provide you
with many years of listening pleasure. Our unit’s esteem arises
from the way we handle music-signals. ADVANTAGE
develops products for people who wish absolutely natural an
enjoyable music reproduction.
Reduction is the principle for the shaping of all
ADVANTAGE components. The unobtrusive design
harmonizes with almost every environment and does not
compete with your personal sphere. The form refers to the
tonal ability of the product line, whose composure and
strength manifests a well-balanced equilibrium.
Design
Due to the extremely short signal paths designed and built
into this piece of equipment, a significant "burn-in" period is
required before the unit will reach its maximum sonic
potential.
We recommend the unit be left on (or in standby mode) at all
times, especially during the first 5-6 weeks of operation, in
order to speed the "burn-in" process.
For best results, the S-250 should be left on or in the standby
mode at all times. The unit should not be switched off via the
master ON/OFF switch unless the unit will not be being used
for a significant period of time (during vacations, etc.).
“Burn-In”
Balanced signal transmission means that two signal lines are
used which carry the same signal with opposite phase. On the
receiving side, the signals are mixed. Since any noise
interference that has arisen during transmission will be
present in both lines with identical phase, such noise is
canceled out, leaving only the pure original signal. Balanced
connection therefore keeps the signal transfer free from any
kind of interference.

Placement
To clean the unit, use only a soft tissue (Kleenex type). Never
apply abrasive cleaners to the outer surfaces of the unit.
Note!
At no time should liquid cleaners be applied directly to the S-
250, as direct application of liquids may result in damage to
electronic components within the unit.
Cleaning
The S-250 Power-amplifier functions best when placed on a
flat, stable surface.
Never place the S-250 near heat sources such as radiators,
stoves, fireplaces or other heat-producing appliances. Avoid
placing the the S-250 where it will be subjected to direct
sunlight or extremely low temperature.

If your volume controlled sources / preamp. are not equipped
with XLR-outputs, please use the line-input with RCA-
connectors.
Balanced Input
(1.)
Plug the female end of the AC cord firmly into the AC
receptacle and make sure that it is properly seated. Connect
the male end directly to an AC wall outlet. Avoid use of an
extension cord or power strip since these often degrade sound
quality. Use the switch (8.) to turn ON/OFF master power.
The balanced inputs are intended to be used if your volume
controlled sources / preamp. have XLR-outputs.

The Data com is used to exchange information with other

power-amplifier to the S-2 preamp you will be able to get

the power amplifier in stand-by mode.

LED / Indicator
(2.) When you turn on the master ON/OFF switch the LED will
flash until all circuits have reached full power. Given that
there are no problems with the Input Signal, such as high DC-
offset, the LED will after a few seconds have a steady light
indicating that the S-250 is in operation. If, however, the LED
starts to flash during operation it means most likely that the S-
250 is overheated. Try turning the master switch off for a
while and then turn it back on.
Standby
(1.) For best results, the S-250 should be left on or in the standby
mode at all times. The unit should not be switched off via the
master ON/OFF switch unless the unit will not be being used
for a significant period of time (during vacations, etc.).

Contact your authorized ADVANTAGE dealer for details of
our warranty policy.
If your ADVANTAGE component must be serviced, please
contact your dealer. Your dealer will then decide whether the
problem can be remedied locally, or whether to contact
ADVANTAGE for further service information or parts, or to
obtain a Return Authorization.
Important!
Return authorization must be obtained from our Technical
Services Department BEFORE a unit is shipped for Service.
It is extremely important that information about a problem be
explicit and complete. A specific, comprehensive description
of the problem helps your dealer and the Technical Services
Department locate and repair the difficulty as quickly as
possible.
A copy of the original bill of sale will serve to verify warranty
status. Please include it with the unit when it is brought in for
warranty service.
Warning!
All returned units must be properly packaged (preferably in
their original packing material), and the proper return
authorization numbers must be marked on the outer carton
for identification. If the packaging to protect the unit is, in our
opinion or that of our dealer, inadequate to protect the unit,
we reserve the right to repackage it for return shipment at the
owner’s expense. Neither ADVANTAGE nor your dealer can
be responsible for shipping damage due to improper (that is,
non-original) packaging.
Your dealer can order a new set of shipping materials for you
if you need to ship your component and no longer have the
original materials. There will be a charge for this service. We
strongly recommend saving all packing materials in case you
need to ship your unit some day.
