REAR PANEL FEATURES AND CONTROLS
MAIN XLR INPUT (BAL/UNBAL)
The system accept female XLR input connectors and line-
level signals from a mixing console or other signal source.
LINK XLR OUTPUT
The output XLR male connector provides a loop trough
for speakers daisy chaining.
VOLUME
Controls the volume of the power amplifier. The control
ranges from -
(maximum attenuation) to the MAX level
(maximum output).
POWER INDICATOR
Power on indicator. When the power cord is connected
and the power switch is turned on this indicator lights
green.
STATUS INDICATOR
The status indicator lights orange if the main amplifier or
power supply is in faulty condition. If the status indicator
lights orange, switch off the amplifier and call the closest
RCF SERVICE CENTRE.
SIGNAL INDICATOR
The signal indicator lights green if there is signal present
on the main XLR input.
LIMITER INDICATOR
The amplifier has a built in limiter circuit to prevent clipping
of the amplifiers or overdriving the transducers. When the
peak clipping circuit is active the LED blinks orange. It is
okay if the limit LED blinks occasionally. If the LED blinks
frequently or lights continuously, turn down the signal
level. The amplifier has a built in RMS limiter. If the RMS
limiter is active the LED lights red. The RMS limiter has
the purpose to prevent damages the transducers. The
speaker shall never be used with the limit indicator red,
continuous operation with the RMS protection active can
cause damages to the speaker.

LF SHAPE
The combination of the 2 switches gives 4 possibilities of
mid low frequencies correction depending on cluster size:
- 1 module (used for pole mount applications)
- 2-3 modules (ground stacking - small flown systems)
- 4-5 modules (medium flown systems)
- 6-8 modules (maximum flown configuration).
HF BOOST
The switch gives the possibility toi set high frequencies
correction depending on target distance (air absorption
correction):
- LINEAR (used for pole mount applications or near field)
- ARRAY (for farthest field).
AC POWERCON RECEPTACLE
RCF NX series uses a POWERCON locking 3-pole AC mains.
Always use the specific power cord provided in the package.
AC POWERCON LINK RECEPTACLE
Use this receptacle to link one or more units. Always make
sure that the maximum current requirement does not
exceed the maximum admitted POWERCON current. In
case of doubt call the closest RCF SERVICE CENTRE.
POWER MAIN SWITCH
The power switch turns the AC power ON and OFF. Make
sure that the VOLUME is set to -
when you turn on the
speaker.
