RCF ART 745-A [5/12] Before connecting the speaker

english

CONNECTIONS

The XLR connectors use the following AES standard:

PIN 1 = GROUND (SHIELD)

PIN 2 = HOT (+)

PIN 3 = COLD (-)

BEFORE CONNECTING THE SPEAKER

On the back panel you will find all the controls, the signal and current inputs. At first verify that the voltage selector on the speaker is in

proper position for your country (115 Volt or 230 Volt).

The switch shall be in proper position (unless moved from unauthorized people), but a fast check will avoid problems. In case is necessary

to change the voltage please call your vendor or authorized RCF SERVICE CENTRE. This operation require the substitution of the fuse value

and is reserved to an RCF SERVICE CENTRE.

BEFORE TURNING ON THE SPEAKER

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.

INSTALLATION

A 35 mm socket for mounting the loudspeaker on a speaker stand is provided in the bottom of the cabinet.

ART speakers MUST be suspended only with approved rigging hardware. In any case always use at least 2 M10 threaded inserts on

opposite sides of the cabinet.

WARNING: Never suspend ART speakers by there handles. Handles are intended for transportation, not for rigging.

PROTECTIONS

ART Series active speakers are equipped with a complete system of protection circuits. Two led on the amplifier back panel indicate the

working status of the amplifier: the green led indicate that the speaker is ON and the red led is on when the protection circuit is active. The

circuit is acting very gently on audio signal, controlling level and maintaining distortion at acceptable level. If this led is ON for a long

period is better to reduce immediately the signal level from the mixer or from the speaker volume control.
