3. FUNCTIONS AND CONTROL
(1) Volume control
Such knob is used for output volume control .
(2) Led and clipping level indicator .
Indicates the output signal level. For a correct amplifier use, the
volume level must be adjusted within the level shown when green
LED ON “SIG” . If the volume level activated LED RED “CLIP” the
output signal is distorted and the volume level should reduced
(3) Led for overload indication
Such led is on when the system is in auto-protection status
(4) Switch ON
