OPERATING THE GRAPHIC EQUALIZER
The graphic equalizer divides the music source into a
number of frequency bands and boosts or attenuates
the level at each of the frequencies, enabling much
finer sound
quality adjustments than ordinary tone
controls and sound field compensation.
Some examples of operation are given below.

RESPONSE
The

response
of a phono-cartridge
or
speaker has peaks and dips in the high range and low
range. It can be made flat by adjusting finely the con-
trols on the graphic equalizer. (See Fig. 3).
[2} IMPROVING THE ACOUSTICS OF
THE LISTENING ROOM
The ideal listening room is one where the transmission
frequency response is flat. In actual fact, however, the
acoustics vary depending on the effects of the struc-
ture of the room and its furniture and on the listening
position.

Although there is minimal treble attenua-
tion in a listening room surrounded
by
hard wails and windows and having a bare
floor, the bass sounds are reflected to a
great extent.
In rooms like this, turn up the 150 Hz con-
trol slightly.

The acoustics undergo change in accord-
ance with the furniture in the listening
room, the height of the ceiling and the
listening position, among
other factors.
Play the music and try operating each of
the controls to produce the best effect.
