RCF BS 2620 - Connection

ENGLISH
Notes:
- to eNsure a correct musical reproductioN, loudspeaker phase is to be respected
(loudspeakers are coNNected respectiNg the amplifier polarity). this is importaNt wheN
loudspeakers are iNstalled adjaceNt oNe aNother, for iNstaNce, iN the same room.
use bipolar cables that have markiNgs to distiNguish the polarity (e.g. iNsulatioN of
differeNt colours, coNductors of differeNt colours, etc.).
- 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 amplifier iNputs.
- the loudspeaker cable shall have wires with a suitable sectioN (twisted, if possible, to
reduce iNductive effects due to surrouNdiNg electro-magNetic fields) aNd a sufficieNt
electrical iNsulatioN. the greater the distaNce betweeN the amplifier aNd the speaker,
the larger the coNNectioN cable cross-sectioN should be to limit the voltage loss
aloNg the liNe.
BS 2620 loudspeakers can be connected to either 100 V constant voltage lines or
amplier low impedance outputs.
The connection to the line is made through the 7-wire cable coming out from the
loudspeaker top.
WARNING: loudspeaker connections should only be 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 and 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.
