Table 4. - Electrical Power Requirements
the individual channel requirements for both idle and full power output and the current requirements for
start-up and full power output.
The start-up current peak is generally higher than the full power output current but because it is very
short, only a rough value can be given. The slow blow fuses commonly used in residential properties do
not notice short start-up peaks, for example, approximately twenty HT205's can be connected to a 10 A
fuse and a single power switch without the start-up current blowing the fuse.

Cable Requirements

Genelec respects the dealer's right to sell customers any good quality cable with good quality termina-
tions that they feel is suitable for the installation. However, a few observations are detailed below:
Loudspeaker cables are not required in Genelec systems (except for the AIW26 and AIW25 In-Walls and
AIC25 In-Ceiling) as the amplifier is, in smaller systems, built into the loudspeaker enclosure. In larger
systems where the amplifier is separated from the enclosure, special Genelec cables are supplied with
loudspeaker system. Custom-made cable lengths are available but, in general, the cable length should
be minimized.
Electrically the main requirements of line level cable are that it has a low capacitance (to avoid a high
frequency roll-off on long cable runs), that it is not microphonic (makes an audible noise through the
loudspeaker when it is moved) and that it is long enough to reach the loudspeaker!

Signal Cable Lengths

Most processors these days have plenty of output level to drive the signal up to about 10 m (30 ft) without
much difficulty. The problem is that they often have unbalanced outputs so that the signal is susceptible
to electrical interference along the entire cable length. In some cases, this may not be a problem if care-
ful consideration has been paid to the physical placement of the cabling away from electrical sources of
noise. In the case of the 6020A, HT205, HT206B, HT208B, HT210B loudspeakers, AIW25 and AIW26
In-Walls, AIC25 In-Ceiling and 5050A, HTS3B, HTS4B & HTS6 subwoofers, unbalanced non-inverting
RCA input connectors are provided together with the XLR input connectors. These are 'either/or' con-
nections so never use both at the same time.
