Important Safety Notice
All connections should be made with the audio
equipment switched off. When using audio equipment
in normal operation, touching uninsulated speaker
terminals or wiring may result in an unpleasant sensation. The
700 S3 speaker terminals accept a variety of cable terminations:
4mm banana plugs, 6mm and 8mm (1/4 in and 5/16 in) spades,
or bare wires up to 4mm (5/32 in) diameter.
Important Safety Notice
In certain countries, notably those in Europe, the use
of 4mm banana plugs is considered a potential safety
hazard, because they may be inserted into the holes
of unshuttered mains supply sockets. In order to comply with
European CENELEC safety regulations, the 4mm holes in the
ends of the terminals are blocked by plastic pins. If you are using
the products in any country where these conditions apply, you
should ensure that any banana plugs cannot be used in an unsafe
manner by children or other uninformed persons. The plastic pins
can be removed if you wish to use banana plugs.

Ask your dealer for advice when selecting speaker cable. Keep
its total impedance below the maximum recommended in the
speaker specification and use a low inductance cable to avoid
attenuation of high frequencies.
There are two linked pairs of terminals on the back of the
speaker. For conventional connection (above left), the terminal
links should remain in place (as delivered) and just one pair of
terminals connected to the amplifier. For bi-wire connections
or bi-amplification (above right), the terminal links should be
removed and each pair of terminals connected to the amplifier or
amplifiers independently. Bi-wiring can improve the resolution of
low-level detail.
Ensure that the positive terminals on the speaker (with red ring)
are connected to the positive output terminal on the amplifier
and the negative terminals on the speaker (with black ring) are
always connected to the negative output terminal on the amplifier.
Incorrect connection will not result in damage but will cause poor
stereo imaging and loss of bass. Always screw the terminal caps
down fully to prevent rattles.
