HF Adjustment
The ‘HF Adjust’ A and B terminals control the
high frequency output of the loudspeaker.
This facility allows the user to adjust the
‘brightness’ of the loudspeaker to suit listening
room acoustics, partnering electronics and
personal taste.
Four settings for tweeter output level are
po0.75, 0 (‘flat’), -0.75 and -1.5dB.For a
‘brighter’ or ‘sharper’ sound 0.75, to
remove brightness select -0.75 or -1.5dB.
The adjustment is made by screwing one,
both or neither of the gold plated screw caps
into the HF Adjust ‘A’ and ‘B’ terminals,
according to the table below. The default setting
is 0 (‘flat’) - one screw cap in terminal ‘B’.
These adjustments as mentioned earlier are
provided not only for ‘room tuning’ but
to allow a more sympathetic partnering to
some electronics.
Amplifiers that may have either a very forward
or bright presentation can be tamed or equally
those that have quite a warm presentation can
be given extra sparkle, it is your choice.

The two centre channel loudspeakers,
Models 202/2c and 204/2c, incorporate a two
position ‘Free Space/Television’ Uni Balance that
adjusts the bass level depending on whether the
loudspeaker is mounted freestanding or close to
a TV or wall boundary. In the Model 202/2c the
‘television’ setting corrects the bass response
for when the loudspeaker is placed on top of,
or directly underneath, a TV. In the Model
204/2c the ‘television’ setting corrects the bass
response for when the loudspeaker is placed on
a stand close to a wall.
HF Adjustment Models 202/2c
and 204/2c
The two centre loudspeakers Models 202/2c
and 204/2c incorporate a two position high
frequency level adjustment which allows
compensation for the sound attenuation when
the loudspeaker is positioned behind a typical
acoustically transparent projection screen,
see below. Select ‘Screen’ when the loudspeaker
is positioned behind a screen.
