ideal when listening outdoor or in low reverberation rooms, at medium distance and at a
medium or high sound pressure level.

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.

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.

3 meter. The preset shows a gentle -3 dB shelf in high frequencies. The sound balance is
natural and never aggressive.

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.

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:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
