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.

LINEAR LOW LEVEL - PLAYBACK. This preset is linear with a 3 dB boost at low
frequency. To be used when playing at low level or for playback music.

ideal for a better sound balance in reverberant rooms and for indoor speech reproduction.

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.

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
- the status yellow led will be blinking slowly, keep the encoder pressed
- the status yellow led will be blinking fast, 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.
The XLR connectors use the following AES standard:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
