RCF HL 2290 [11/28] Connection

ENGLISH

Then, x the rear bracket, by using the hole corresponding to the proper angle.

If the angle between two cabinets is set to 0°, it will be necessary to add the

additional rear linking plate.

WARNING: loudspeaker connections should be only made by qualied and experienced

personnel having the technical know-how or sufcient specic instructions (to ensure that

connections are made correctly) in order to prevent any electrical danger. To prevent any

risk of electric shock, do not connect loudspeakers when the amplier is switched on.

Before turning the system on, check all connections and make sure there are no accidental

short circuits.

The entire sound system shall be designed and installed in compliance with the current

local laws and regulations regarding electrical systems.

To ensure a correct sound reproduction, loudspeaker phase is to be respected (loudspeakers

are connected respecting the amplier polarity).

To prevent inductive effects from causing hum, noise and a bad system working, loudspeaker

lines should not be laid together with other electric cables (mains), microphone or line level

signal cables connected to amplier inputs.

The loudspeaker cable shall have wires (twisted, if possible, to reduce inductive effects due

to surrounding electro-magnetic elds) with a suitable section (min. 1.5 mm² – max. 2.5

mm²) and a sufcient electrical insulation.

NEVER connect HL series (and HS 2200) speakers directly to 70 / 100 V constant voltage

lines.
