• MONITOR menu
VU-meters monitoring scale selection:
o
Output power (Watts), RMS or peak.
o
Output voltage (Volts), peak or RMS.
o
Input signal voltage, RMS.
Display through dedicated screens:
o
Load impedance, in ohms.
o
Temperature, in % of the alarm triggering temperature.
o
AC power supply voltage.
o
Cumulative operating time of the amplifier, in hours: minutes.
o
Events: digital counter of protection alarms, thermal, load impedance, AC power supply
voltage (note: from within this menu, alarm counters can be reset (value = 0) for each channel
by holding down the rotary knob for a short period of time).
• SETTINGS menu
Amplifier operating mode menus:
o
INPUT SOURCE: selects the input signal for the amplifier to work with, amongst the available
ones (Analog 1, Analog 2, Digital 1, Digital 2 and internal generator).
o
LINK VOLUME: determines whether the volume controls on both channels of the amplifier will
be linked (ON) or independent (OFF). In linked mode, the CHANNEL 1 rotary knob sets the
volume for both channels simultaneously and the label "LINK" is displayed.
o
GAIN: selectable amplifier gain between 26, 32 or 38 dB.
o
OUTPUT MODE: operating mode selection for amplified outputs between stereo, parallel or
bridge. For the two last ones, the label "PARAL" or "BRIDGE" is displayed.
o
POLARITY: phase selection for the input signal, normal or inverted. The label "INV" is
displayed if the phase is inverted.
o
ANTICLIP LEVEL: anti-clipping circuit level selection between soft (allowing a large clipping),
medium or hard (allowing a minimum clipping, almost negligible).
o
PEAK LIMITER: allows defining a maximum voltage for the unit amplified outputs.
• PRESETS menu
Amplifier PRESETS selection in a list of 10 available memories.
Note: when loading a PRESET, its number and name appear on the top line of the display. When
you modify any setting of the amplifier an "M" label appears in the upper right corner of the screen
to indicate that the PRESET has been modified (for example, moving a volume control is sufficient
to make it happen).
