Thank you for purchasing the ADVANTAGE S-150 Power-
amplifier.
Your S-150 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 tothe 
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-150 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.
