12 CARDIOID SET-UP SWITCH. This switch provides a special equalisation and delay setting to
create a cardioid pattern when the system is used in conjunction with two other sub 8006-AS
modules.
POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure that
13
the sensitivity is set to + ∞ dBu when you turn on the speaker.
14 AC POWERCON RECEPTACLE. RCF SUB series uses a POWERCON locking 3-pole AC
mains. Always use the specific power cord provided in the package.
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 turn-
ing 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 im-
mediately 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.
To set the system time delay rotate to the wanted delay setting. When using multiple sub-
woofers set carefully all the subwoofers in the same group to the exact same delay.
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,...).
