BEFORE CONNECTING
THE SPEAKER
TIME DELAY SETTING
The XLR connectors use the following AES standard:
PIN 1 = GROUND (SHIELD)
PIN 2 = HOT (+)
PIN 3 = COLD (-)
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.
The delay is expressed in meters. The delay resolution is 0.1 up to 10 meters and 1 from
10 to 20 meters.
To set the system time delay push the delay encoder and rotate it until the wanted setting
is displayed. Push the encoder again to confirm the setting.
It is possible to create subwoofer cardioid systems using groups of three modules .
A group is made of three modules, the group shall be made as follow:
- 2 modules pointing in forward direction, cardioid switch released.
- 1 module pointing in backward direction, cardioid switch pressed.
- All 3 modules shall have the same settings (SYSTEM DELAY, SENSITIVITY, X-LOW
CUT, X-OVER,…).
