d.
BASS control modifies lower frequencies output signal. Set this control
level by personal taste and ambient acoustic character.
e.

control level by personal taste and ambient acoustic character.
f.
INPUT1, INPUT2, INPUT3, INPUT4 and AUX INPUT have their own
independent volume control. These controls will allow to set the
intensity of each program source, in order to obtain the desired levels.
g.
Turning clockwise the MASTER volume control, the listening level will
raise, turning it counter clockwise it will be lower. To get the best
performances MASTER volume should be set to obtain an output level
between –20 dB and 0 dB, as shown by 5 lower LEDs. Make sure the
two higher LEDs (+3dB and +6dB) are not lit. These LEDs will indicate
that signal is distorted and that MASTER volume should be decreased.
