TTL6-A PRESETS
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.
TTL6-AS PRESETS
L1 - L2 - L3 - L4. EXTENDED LOW. These presets apply respectively four frequency cut-offs to use this
speaker as subwoofer of other RCF TT+ speakers.
S1 - S2. SIDE POSITIONING. These presets were developed to couple this speaker with TTL6-A when this
is configured with presets S1 e S2.
V1 - V2. VERTICAL POSITIONING. These presets were developed to couple this speaker with TTL6-A when
this is configured with presets V1 e V2.
SE - LE. LOW PASS EXCLUDED. These presets are “free“, full range, developed to freely create cut-offs
and cossing as desired.
After the parameter settings the 2 digits display will flash one time. This represents 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:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
70° - 80°
