L1. LINEAR. Is the totally linear preset. The speaker curve response is perfectly linear. It is ideal when listening outdoor or in low reverberation rooms, at medium distance and at a medium or high sound pressure level.
L2. LINEAR HIGH PASS. This preset is the same as L1 with a 24 dB/oct. high pass filter at 100 Hz. To be used when the speaker is a part of a bigger system, when is a satellite of a subwoofer system or when the application is speech reproduction.
L3. LINEAR LOW LEVEL - PLAYBACK. This preset is linear with a gentle +3 dB boost at low frequency. To be used when playing at low level or for playback music.
L4. LINEAR INDOOR. This preset is linear with a gentle -3 dB shelf at low frequency. It is ideal for a better sound balance in reverberant rooms and for indoor speech reproduction.
C1. CLOSE. Close listening preset. To be used when the average listener is closer than 3 meter. The preset shows a gentle -3 dB shelf in high frequencies. The sound balance is natural and never aggressive.
C2. CLOSE HIGH PASS. This preset is the same as C1 with a 24 dB/oct. high pass filter at 100 Hz.
F1. FAR. Far listening preset. To be used when the average listener distance is more than 10 meter. The preset shows a +3 dB shelf in high frequencies to compensate the air absorption. The clarity and intelligibility in distance are improved.
F2. FAR HIGH PASS. This is the same as F1 with a 24 dB/oct. high pass filter at 100 Hz.

Only for TT 25-CXA and TT 45-CXA, instead of presets L3 and L4:

M1. MONITOR PRESET. This preset is linear when the speaker is in a floor monitor position. This preset is specifically designed for vocal or instrument monitoring. Intelligibility and vocal reproduction are optimized, time delay is minimized.

M2. 2 X MONITOR PRESET. This preset is linear when the speaker is in a floor monitor position and two speakers are used in couple. This preset is specifically designed for vocal or instrument monitoring. Intelligibility and vocal reproduction are optimized, time delay is minimized.

After the parameter settings the 2 digits display will flash one time. This represent saving all the preset values in the speaker memory.

Once saved, all the speaker settings are permanent. It is possible to turn off and turn on, the speaker will remember the last settings.

To reset the speaker to the original settings :

• turn off the speaker
• keep the encoder pressed
• turn on the speaker
• with an intermittent signal of two circular symbols the display will indicate the reset procedure has begun
• release the encoder
• once the display will turn off the reset procedure is completed

Using the RDNet IN/OUT connection it is possible to load in the speaker memory a dedicated user equalisation. The speaker reset procedure will cancel even this equalisation.

The XLR connectors use the following AES standard:

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

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

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

CONNECTIONS

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: daisy chaining speakers 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.

WARNING: The powercon connector is used to disconnect the system from the power supply network. It shall be easily accessible after the installation and during the use of the system.
