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
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.
