ENGLISH
MAIN XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and
line-level signals from a mixing console or other signal source.
SIDE COUPLING. The system provides linear equalisation in case of a single speaker
in floor monitoring position. In case of coupled application (2 speakers side by side) this
switch equalise the curve response reducing the low-mid and low frequency range.
This switch can be used even for a single speaker when a very high intelligibility is required
from the monitor.
INPUT SENSITIVITY. Controls the overall signal level at the input to the power amplifier.
The control ranges from +
∞
(maximum attenuation) to the –2 dBu sensitivity (maximum
input gain). The centre detent is +4 dBu (nominal level required to drive the amplifier at
maximum power).
LIMIT INDICATOR. The amplifier has a built in limiter circuit to prevent clipping of the
amplifiers or overdriving the transducers. When the soft 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.
SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the
main XLR input.
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.
POWER INDICATOR. Power on indicator. When the power cord is connected and the power
switch is turned on this indicator lights green.
SIDE
PANELS
The total available power supply power is 750 watts and can be distributed to the 2 final
amplifier sections. Each amplifier section has a very high maximum output power capability
in order to provide, when necessary, maximum output bursts in a specific frequency range.
