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 and crossover out if LINK/XOVER switch is pressed.
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.
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.
HIGH PASS. The switch gives the possibility to set high pass filter at 30 Hz or
45 Hz.
LOW PASS. The switch gives the possibility to set low pass filter (crossover point)
at 90 Hz or 140 Hz.
PHASE. The switch gives the possibility to rotate the phase of 180° (phase
reverse).
LINK/XOVER. The switch enables the XLR link/xover output to daisy chain the
signal or to add the crossover filter to the output signal.
- LINK (daisy chain the input signal).
- ON (add the crossover filter to the output signal).
AC POWERCON RECEPTACLE. RCF D Line 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.
