7.5. CLIP indicators
“CLlP” indicators light up when the signal is near the real clipping (saturation) level. It is
normal for CLIP indicators to be lit at the bass frequencies rhythm for high operating levels, as these
frequencies have the higher energy content. You must take care that these indicators do not remain
continuously lit.
7.6. VOLUME control knob
The front panel VOLUME control knob has three functions:
•
Adjusting the unit output volume, when you turn it
•
Activating the unit's mute function, when you press it
•
Deactivating the unit's mute function, when you press it again or turn it
The MUTE LED indicator lights up in red when the unit is muted.
Last volume setting is stored and at power-on the unit will be set to the same volume level as
when it was last turned off.
NOTE: if the unit is muted by the back panel MUTE external contact closure or opening,
all front panel and remote handset controls are deactivated. If MUTE is externally activated while the
device is already muted, the device remains muted after the end of the external activation.
7.7. Auto-Standby function
The unit automatically enters standby mode (low power consumption) after two minutes of
no input signal. In standby mode, the front panel ON LED indicator has a variable light intensity that
increases and decreases according to a slow cycle. In this mode, the other LED indicators are
permanently switched off.
The PKUB wakes up again in following conditions:
•
An audio signal is detected on any input
•
Any key of the remote control is pressed. Its assigned command is NOT executed
that time
•
The volume is changed (UP/DOWN) or the front panel VOLUME control is pressed.
The assigned command is NOT executed that time
•
A status change has been detected at the external MUTE input. The assigned
command IS executed
•
Auto Standby can be deactivated with the back panel switch
If the unit was muted before entering the standby mode, the MUTE LED indicator is
switched off in standby mode and lights up when the unit is switched ON again.
