Close
proximity
of the
control unit and tuners to
each
other
should cause
no
problem
unless the
control
unit is mounted immediately
on top of the tuner,
in
which
case a
space of about two inches
should be
left
between
them.
Hum
can also occur if a low
output magnetic
pickup
is too
close to a mains
transformer
or
if its leads
run
close to the mains wiring.
(See
Fig. 2).
All
metal
parts
must
be earthed but,
because
multiple
earth connections
cause hum,
they
should be earthed,
directly or indirectly,
by
one connection
only, and the
whole installation
earthed at
one
point
such as the E
terminal
on the
rear
of the
control unit,
OR the third
pin
of the
control unit mains
socket, but not
both.
(Note:
All
the
Quad
units are already
bonded
together
by their
own inter-connecting
cables).
Always
follow
the
manufacturers'
instructions
supplied
with
pickup,
motor,
tape recorder,
etc., and refer
any
query
which may
arise
to
your
dealer
or
in
case of
difficulty
to the manufacturer
concerned.

If the
Quad
33
is not
to be
used free
standing
you
will require
an aperture
lA' x
3" as shown in Fig.
3
and a template is
provided
in
the rear
of
this
booklet
to assist in marking
this
out on the
cabinet.
The
cover
is
then
removed
from
the
Quad
33, the unit
p'assed
through the aperture from
the front
so that its lugs
locate
in the aperture, and
the
cover
replaced
from
the
rear,
thus
gripping
the
cabinet
panel
between the
Quad
33 front
casting
and its
cover.
The
securing
screws
should be
inserted finger
tight and
then
given
one
further
half-turn
to
lock
the unit firmly in
position.
