ENGLISH
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 (-)
It is possible to create subwoofer cardioid systems using groups of two or three modules.

- Only use one of the L presets (30 Hz High Pass filter)
- 1 modules pointing in forward direction
- 1 module pointing in backward direction, correspondent cardioid preset
- The modules shall have the same settings (system delay, sensitivity, preset)
A group of three modules shall be made as follow:
- Only use one of the L presets (30 Hz High Pass filter)
- 2 modules pointing in forward direction
- 1 module pointing in backward direction, correspondent cardioid preset

INSTALLATION
SERVICE NOTE
At this point you can connect the power supply cable and the signal cable, but before turning
on the speaker make sure that 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
damage to the speakers and noisy “bumps” due to turning on parts on the audio chain. It is a
good practice to always turn on speakers at last and turn them off immediately after the show.
Now you can turn ON the speaker and adjust the volume control to a proper level. BEFORE TURNING ON
