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.
