2 MAIN SIGNAL XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and line-level
signals from a mixing console or other signal source.
3 XOVER SIGNAL OUTPUT(BAL/UNBAL
signal (24 dB/octave) for satellites speakers.
4 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.
5 SIGNAL INDICATOR. The signal indicator lights green if there is signal present on the main XLR inputs.
6 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.
7 POWER INDICATOR. Power on indicator. When the power cord is connected and the power switch is turned
on this indicator lights green.
8 INPUT SENSITIVITY
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).
9 PHASE 0/180°. This switch invert the phase of the system 180°.
10 AC POWERCON RECEPTACLE. RCF TT+ series uses a POWERCON locking 3-pole AC mains. Always
use the specific power cord provided in the package.
11 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.
12 POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure that the sensitivity
is set to +∞ when you turn on the speaker.
13 EARTH connection.
CONNECTIONS
The XLR connectors use the following AES standard:
PIN 1 =
PIN 2 =
PIN 3 =
BEFORE TURNING ON THE SPEAKER
At this point you can connect the power supply cable and the signal cable, but before turning on the speaker make
sure that the volume control is at the minimum level (even on the mixer output). It is important that the mixer is
already ON before turning on the speaker. This will avoid damage to the speakers and noisy "bumps" due to
turning on parts on the audio chain. It is a good practice to always turn on speakers at last and turn them off
immediately after the show.
Now you can turn ON the speaker and adjust the volume control to a proper level.
INSTALLATION
A pole mount adapter for mounting a loudspeaker on top of the subwoofer.
Always make sure that the pole mount that is used is able to sustain the speaker weight with a proper safety factor.
WARNING: Never suspend TTS12-A subwoofers, never suspend by there handles. Handles are intended for
transportation, not for rigging.
:
WARNING 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.
