CONNECTIONS
AC POWERCON RECEPTACLE. RCF D LINE uses a POWERCON locking 3-pole AC
mains. Always use the specific power cord provided in the package.
AC POWERCON LINK RECEPTACLE. Use this receptacle to link one or more units.
Always make sure that the maximum current requirement does not
exceed the maximum admitted POWERCON current. In case of doubt call the closest RCF
SERVICE CENTRE.
POWER MAIN SWITCH. The power switch turns the AC power ON and OFF. Make sure
that the VOLUME is set to - when you turn on the speaker.
FUSE.
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.
WARNING: Always make sure that the maximum current requirement does not exceed
the maximum admitted POWERCON current. In case of doubt call the closest RCF SERVICE
CENTRE.
230 Volt, 50 Hz SETUP: FUSE VALUE T3,15A - 250V
115 Volt, 60 Hz SETUP: FUSE VALUE T6, 30A - 250V
Audio signal can be daisy-chained using the male XLR loop through connectors. A single
audio source can drive multiple speakers modules (like a full left or right channel made of
8-16 speaker modules); make sure that the source device is able to drive the impedance
load made of the modules input circuits in parallel. The HDL line arrays input circuit presents
a 100 KOhm input impedance. The total input impedance seen as a load from the audio
source (ex. audio mixer) will be:
- system input impedance = 100 KOhm / number of input circuits in parallel.
The required output impedance of the audio source (ex. audio mixer) will be:
- source output impedance > 10 * system input impedance;
- always make sure that XLR cables used to feed audio signal to the system are:
- balanced audio cables;
- wired in phase.
A single defective cable can affect the performance of the overall system!
