A

WORD

ABOUT

ROOM

ACOUSTICS

The sound

that

you

hear

is

greatly

influenced

by

the

size

and

shape

of

the

room,

by

the

location

of

the

loudspeakers,

by

the

materials

used

for

the

walls,

ceiling

and

floor,

by

the

amount

and

distribution

of

furniture,

carpets,

draperies.

Generally,

it is

advisable

to

place

the

speakers

with

their

backs

against

a

wall

as

this will

improve

bass

response.

Bare

rooms

with

low

ceilings,

hard

floors

and

hard,

reflective

walls,

especially

a

hard

wall

facing

the

speakers,

can

cause

very

“live,”

brilliant

sound

with

lack

of

clear

instrument

localization

and

definition.

In

such

a

case,

it

usually

helps

to

puta

carpet

and

heavy,

soft

curtains

in

the

room.

Conversely,

rooms

with

heavy

carpeting

and

a

great.

deal

of

upholstered

furniture

make

the

sound

“dead”

—

often,

re-arranging

the

furniture

helps

in

this

case.

SPEAKER

SYSTEM

CONNECTION

Two

sets

of

connect

them

follows.

See

in

the

way.

NOTE:

When

two

pairs

(A+B)

of

speakers

are

to

be

used

at

the

same

time,

each

speaker

must

have

an

impedance

of

8

or

more.

SWITCH

(5

In

move

the

switch

to

either

“SOs”

or

Be

to

set

the

only

when

so

that

NOTES:

1.

You

should

use

high

impedance

(above

20k)

microphones

of

the

dynamic

type,

with

standard

6mm

diameter

phone

plugs.

Pioneer

puts

on

the

market

a

wide

variety

of

high

performance

microphones

for

your

selection.

2.

It

is

readily

possible

for

microphone,

under

certain

conditions

of

use,

to

give

rise

to

“howling”

feedback

noise.

Be

careful

not

to

raise

the

volume

too

high

when

the

microphone

is

close

to

the

speaker

systems

or

in

a

room

with

a

great

deal

of

resonance.

It

is

most

effective

in

using

the

TREBLE

and

BASS

controls

at

their

midway

positions.

TAPE

DUPLICATING

With

two

tape

decks,

you

can

duplicate

tape-to-

tape,

or

edit

recordings

while

re-recording.

For

example,

you

can

first

tape

a

complete

FM

stereo

program,

with

announcements

and

commercials,

and

later

re-record

on

another

tape

while

cutting

out

unwanted

portions.

For

duplicating

proceed

as

follows:

1.

Connect

two

tape

decks

as

shown

in

Fig.

12.

2.

Set

the

FUNCTION

switch

to

and

re-

produce

3.

Record

the
