INSTALLATION
The ESL loudspeaker requires an energising voltage for operation and therefore
needs to be connected to an AC power supply.
Checking the AC power supply
The ESL loudspeaker is designed to operate on one range of AC power supply only,
50/60 Hz. Either 200-240V or 100/120V. The correct operating voltage is clearly
marked on the base. It may be changed from 220V to 110V operation or vice versa
by a suitably qualified technician.
Before connecting to the AC power supply check that the voltage range
marked on the base corresponds with that of the supply.
Connecting to the AC Power Supply (UK only)
The ESL is supplied with an AC power lead with a moulded 13A 3 pin plug with 3A
fuse. Do not cut off this plug or use it with its fuse cover removed. If however for any
reason the plug has to be removed then it must be disposed of and under no
circumstances plugged into a 13A socket outlet. A suitable plug can be fitted, as
explained below:
IMPORTANT: Fitting a mains plug.
The wires in the mains lead are coloured:
Brown = Live Blue = Neutral
The Brown wire must be connected to the terminal marked L or coloured Red. The
Blue wire must be connected to the terminal marked N or coloured Black. If the
lead also has a Green/Yellow wire than this must be connected to the terminal
marked E or coloured Green or Green/Yellow.
Note: When a fused 13A plug is used a 5A fuse (ASTA approved to BS1362) will
be adequate for a typical Quad system. For other types of plug, then fit a 5A fuse
either in the plug, or adaptor, or at the distribution board. If in doubt consult a
qualified electrician.
Connecting to the AC Power Supply (other markets)
The ESL should be supplied with a power lead terminated with the correct plug to
match your local regulations. If the plug is an incorrect type or if you experience any
problems with installation you should consult your dealer or local Quad distributor.
Connection to the Amplifier
Audio input is via binding posts. For runs up to 10m a cable with a rating of 6A
(24/0.2mm) should be adequate. Longer runs may require heavier cable. The basic
rule is that the total resistance of the cable should not exceed 5% of the loudspeaker
impedance, ie 0.4 Ohms. Inductance should not exceed 1mH per metre and
capacity can be ignored.
