The connectors must be wired according to the standards specified by the AES (Audio Engineering Society)�
BEFORE CONNECTING THE SPEAKER
On the rear panel you will find all the controls, signal and power inputs� At first verify the voltage label applied to the rear panel (115 Volt or 230
Volt)� The label indicates the right voltage� If you read a wrong voltage on the label or if you can’t find the label at all, please call your vendor or
authorized RCF SERVICE CENTRE before connecting the speaker� This fast check will avoid any damage�
In case of need of changing the voltage please call your vendor or authorized RCF SERVICE CENTRE� This operation requires the replacement of
the fuse value and is reserved to an RCF SERVICE CENTRE�
BEFORE TURNING ON THE SPEAKER
You can now connect the power supply cable and the signal cable� Before turning on the speaker make sure 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 damages to the speaker
and noisy “bumps” due to turning on parts on the audio chain� It is a good practice to always turn on the speakers at last and turning them off
immediately after their use� You can now turn ON the speaker and adjust the volume control to a proper level�
PROTECTIONS
The speakers are equipped with a complete system of protection circuits� The circuit is acting very gently on audio signal, controlling level and
maintaining distortion at acceptable level�

PART 1 | 5. PRESETS
IMPORTANT NOTE: The following presets are valid for TTL 4-A, TTP 4-A and TTW 4-A only.
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�
S1, S2 - SIDE COUPLING PRESETS These presets are linear when the speaker are coupled side to side�
These presets are properly designed for speakers coupled with a horizontal coupling angle from 70° to 80°�
The front of the cabinets shall be split and the rear of the cabinets shall be close� The S2 preset features
the low frequency high pass filter�
U1, U2 - VERTICAL COUPLING PRESETS These presets are linear when the speaker are coupled
vertically� The vertical coupling angle can vary from 0° to 10° in 2° steps� Smaller coupling angles offers a
narrower directivity but a better sound projection and far distance definition� The U2 preset features the
low frequency high pass filter�
After the parameter settings the 2 digits display will flash one time�This means saving all the preset values
in the speaker memory�
Once saved, all the speaker settings are permanent� It is possible to turn the speaker off and on and the last settings will be remembered�
To reset the speaker to the original settings :
1. Turn off the speaker
2. Keep the encoder pressed
3. Turn on the speaker (The status yellow led will blink slowly, keep the encoder pressed)
4. Wait until the 2 digits display will turn to show the completed reset procedure
6. Now release the encoder
The reset procedure is finished
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�
