microphone.

The HME

1019 headphone /microphone

combi-

nation

can

be

connected

directly to the

1019

simultaneous

interpreter

system

(see

page 81).

The

headphone

/microphone combination

has

been designed and developed

for

continuous use

and

is

therefore

fitted with an

extremely

light-

weight HD 400 headphone which can be

worn

comfortably

for long periods

of

time. To keep the

combination

down to a

lowest

possible total

weight

of

130

g

an electret

microphone has

been used,

in

this case a noise cancelling

electret condenser

microphone. The HME

1019 headphone /micro-

phone

combination

provides the ideal solution

for

working in

noisy surroundings, e. g.

in news

reporting or wherever

loud noise

can

prove

disruptive, as

for

example

in a

simultaneous

interpreting system. This

is where

the

noise

cancelling

electret

microphone

comes

into its own.

It is designed

for

close -talking

and positioned at

mouth level. Exact positioning can be

adjusted

through a 360 ° arc and

which can also be

mounted

either

left

or

right

and bent easily toward or

away

from

the

mouth. The ideal distance from

micro-

phone to mouth should be about

2

cm or

1 inch.

Another advantage

is achieved by use of the

extremely

lightweight HD

400 headphone

capsules

in conjunction

with

a specially developed

head-

band. With a total weight of

130

g (including

micro-

phone

this combinaton

is

ideal for

comfortable

wearing

for

a period of

hours

on end.
