recommended by the manufacturer. The equipment / support / trolley assembly must be moved with extreme caution. Sudden stops, excessive pushing force and uneven floors may cause the assembly to overturn.

1. There are numerous mechanical and electrical factors to be considered when installing a professional audio system (in addition to those which are strictly acoustic, such as sound pressure, angles of coverage, frequency response, etc.).

2. Hearing loss

Exposure to high sound levels can cause permanent hearing loss. The acoustic pressure level that leads to hearing loss is different from person to person and depends on the duration of exposure. To prevent potentially dangerous exposure to high levels of acoustic pressure, anyone who is exposed to these levels should use adequate protection devices. When a transducer capable of producing high sound levels is being used, it is therefore necessary to wear ear plugs or protective earphones. See the manual technical specifications to know the maximum sound pressure level.

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.

SIDE PANELS

1 MAIN XLR INPUT (BAL/UNBAL). The system accept female XLR input connectors and line-level signals from a mixing console or other signal source.
2IDE 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.
3 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).
4 MIT 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 input.
6ATUS 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.

8AC POWERCON RECEPTACLE. RCF TT+ series uses a POWERCON locking 3-pole AC mains. Always use the specific power cord provided in the package.
9 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.
10 GROUND.

11NK XLR OUTPUT. The output XLR male connector provides a loop trough for speakers daisy chaining.
12C 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.
13 GROUND.

The XLR connectors use the following AES standard:

$$ \text { PIN } 1 = \text { GROUND (SHIELD) } $$

$$ \text { PIN } 2 = \text { HOT } (+) $$

$$ \text { PIN 3 } = \text { COLD } (-) $$

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.

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.
