10 Protection system
Your Audionet SAM G2 and your loudspeakers are protected by a com-
plex protection circuitry. In case of a malfunction the display informs the
user about the nature of the detected error in plain text:
Error message Possible cause
Overload short circuit or defective speaker
Overheating
ventilation slots covered
High Frequency defective pre amplifier-stage
DC Voltage
exceeding DC level at the output:
defective pre amplifier-stage or source unit
Power Failure (temporary) breakdown of mains
Even after powering down the SAM G2, the error message will still be in
the display. Press the
power key on the front panel to indicating the
stand-by mode.
Important
·
Remove cause of error prior to switching on the SAM G2 again!
11 Technical information
11.1 Design
With circuits consequently designed using SMD miniature technology
and shortening all signal paths to a minimum the high frequency charac-
teristics were optimized. Ground pathways run in a star-shaped pattern
converging in one central location. The circuit design is optimized ca-
pacitively and inductively. A powerful microprocessor controls and
monitors the system.
11.2 Power Supply
The mains supply is extremely potent and very fast. This is guaranteed by a
capped and fused 700 VA toroidal transformer, selected main filter capacitors
with a total of 96.000
μ F smoothing capacity, a specially developed input filter
and highly pure silver cabling as well as a capacitively optimized layout with
the shortest of supply routes.
