FUNCTION
SELECTION
LEVEL CONTROL
INPUTS
ON
Lit when the
amplifier is ON.
MODE
STEREO:
The amplifier is se-
lected as stereo.
MONO IN R:
The amplifier is se-
lected as mono.
Right input is used.
PRE IN
Left - Right inputs
of the amplifier.
They can be used to
amplify the PRE out-
put of a signal source
(radio, CD-DAT), an
electronic crossover
output or an output
of any kind of signal
processor at pream-
plified level.
LEVELS
Level control for the
amplifier output.
Sensitivity varies
from 150mV to
1.5V.
SAFE
When lit it indicates
the intervention of
pro-tection circuits:
in case of overhea-
ting (temperature
exceeding 80° C /
176° F) or output
anomalies (presence
of continuous cur-
rent, short circuit, or
dangerously low load
impedance).
When protection cir-
cuits intervene the
amplifier shuts
down. Turn the am-
plifier off.
When the problem is
corrected turn the
amplifier back on.
