by experiment. Few
people
can successfully
complete
these
experiments
at
a single session
and
it is
strongly
recommended
that the
following
procedure
be adopted.
The loudspeaker(s)
should
be tried in
the
various
room
positions
which
appear
physically
possible,
in
order to ascertain
which
positions
are likely to be
worth further investigation.
The loudspeaker
should
now
be
used in
each
of
these
positions
for normal
day to day
listening.
The
usual attention
should
be
paid
to the
programme
itself without any conscious
concentration
on the
quality.
In this
way
the optimum
position
for most
satisfactory listening
will
soon
become apparent.
OPERATION
SUMMARY
With all the tests detailed
in the
previous
section
completed, operation
of the
Quad
33 should
now be
readily apparent
and completely straightforward.
It
may
be summarised
as follows:-
Use
the
pushbuttons
to select
input
and system
required.
Adjust the
volume
control
for
a
level
of sound suit-
able
for the
programme.

Adjust the filter
to obtain
the
best
quality
inherent
in
the
programme
remembering
that
this means filter-
ing as little
as
possible.
Adjust
bass and treble
controls only if it is
neces-
sary to
alter the musical
balance
of
the
programme.
Adjust the
balance control
only
if
the
programme
levels
of the two channels
are themselves
out of
balance.
