MAINS WORKING VOLTAGE AND FUSE RATINGS
The rated voltage for this unit is marked on the rear panel. Please check with the
dealer if you intend to use the equipment in regions which use different values of
mains voltage.
QUAD manufactures equipment to the following nominal mains voltages.
230VAC - Europe & UK 115VAC - USA, etc
100VAC - Japan, etc 220VAC - Korea, etc
If you are in any doubt what the voltage is in your area you should ask a
qualified electrician before applying power to the equipment. Your QUAD
equipment will work within standard tolerances of the nominal voltage.
 QUAD II – forty. The mains supply fuse is on the rear panel and
accessible when the IEC mains plug is removed. If it has broken you should
check for any obvious cause before replacing the fuse with one of the correct
rating and type.
 QUAD QC – twenty four. The mains supply fuse is on the rear panel
and accessible when the IEC mains plug is removed. If it has broken you
should check for any obvious cause before replacing the fuse with one of the
correct rating and type.
The mains supply fuse ratings for each product are listed in the table below:
MAINS CONNECTIONS
QUAD equipment supplied in Europe is provided with a mains cable fitted
with an appropriate mains plug. This plug should not be cut from the cable
or used with its fuse cover removed. If, for any reason, the plug is removed, it
must be safely disposed of. It must never be re-used.
A replacement plug should be wired to the supplied mains cable as follows:
 The Brown wire must be taken to the LIVE terminal.
 The Blue wire must be taken to the NEUTRAL terminal.
 The Green/Yellow wire must be taken to the EARTH terminal.
In the UK a fused 13 Amp mains plug should be fitted with a fuse link rated
at 5 Amps. In other countries a value between 10 and 15 Amps should be
used at either the wall socket or the mains distribution board.
When you are trimming or cutting cables and wires you should prevent the
waste parts from falling onto or into any electrical equipment. If you are in
any doubt you should consult a qualified electrical engineer.
The power supply input to your QUAD equipment is via an IEC mains
connector and an appropriate mains lead is supplied. For optimum
performance each unit should be connected to a properly installed mains
power socket. If you need to use a mains distribution unit, please ensure that
it is a safety-approved unit of appropriate rating and that it is used exclusively
to supply audio components.
These QUAD components must be connected to an earthed (grounded) AC
supply. If you are uncertain if the mains supply in your house is efficiently
earthed, you should consult a qualified electrical engineer.

QUAD II –
Connecting the QUAD QC – twenty four to the QUAD II – forty (refer to fig. g above)
Decide which of the two power amplifiers is to be the left channel and which
the right channel and place the units in their intended locations having
regard to the suggestions on page 7.
 Using an appropriate screened RCA phono cable, connect the INPUT
socket g of each QUAD II – forty to the requisite OUTPUT socket (fig. c
page 8) of the QC – twenty four.
 The interconnect leads should be the same length regardless of the
placement of the power amplifiers relative to the preamplifier.
 Take care when running signal cables to keep them away from sources of
interference and noise.
 Do not run signal cables parallel to mains cables or lines carrying digital
traffic.
FINAL SYSTEM CONNECTIONS
When all the sources have been connected, the power amplifiers are fully
connected to the loudspeakers and the preamplifier, and all system
connections have been double-checked, the final process is to connect the
mains. Ensure that the mains switches b on the rear panels of the QUAD II
– forty power amplifiers are switched OFF.
 Ensure that the ON/OFF switch on the front panel of the QC – twenty
four is set to the OFF (fully extended) position.
 Ensure that the volume control on front panel of the QC – twenty four is
at the minimum (fully anticlockwise) position.
 Plug the three supplied IEC leads into their respective mains input
sockets on each QUAD unit.
 Plug the IEC leads into the wall sockets and switch these sockets on.
 Plug in the mains leads and switch on the power to your source units.
 The system is now fully connected and ready for operation.
