ADJUSTMENT

OF

THE

DIRECT

ENERGY

CONTROL

The

Direct

Energy

Control

has

been

carefully

designed

to

provide

the

optimum

performance

of

the

Model

501

under

a

wide

range

of

listening

conditions.

This

control

affects

the

spatial

distribution

of

high

frequency

energy.

At

distances

close

to

the

loudspeaker,

the

listener

will

notice

significant

changes

in

high

frequency

energy.

However,

the

effect

be-

comes

subtle

with

increasing

distance

from

the

speaker

and

will

be

less

noticeable

in

larger

rooms,

where

the

listener

is

principally

in

the

reverberant

field.
