INFORMATION

About

Fixed-Level

Outputs

A

fixed-level,

or

line-level

audio

output

is

considered

ideal

since

it

provides

an

audio

signal

unchanged

by

adjustments

to

the

audio

source

(stereo,

etc.)

volume

control.

Hint:

Fixed-level

audio

outputs

from

stereo

receivers/amps

will typically

be

desig-

nated

as

Tape,

Tape

1,

and

Tape

2

outputs,

OAT

(digital

audio

tape)

outputs,

VCR

audio

output

connections,

and

auxiliary

audio

outputs.

Tape,

Tape

1,

Tape

2

and

OAT

outputs

are

usually

marked

as

ITAPE

OUTPUT;'

ITAPE

OUT;'

ITAPE

REC,'

or

TAPE

RECORD.'

Jacks

designated

for

phono,

CD,

LD,

DVD

or

tape

playback

(PB)

are

inputs

and

will

not

work

for

purposes

of

installing

the

transmitter.

Fixed-level

outputs

from

TVs

are

usually

marked

as

'Constant,'

'Fixed,'

or

'Select.'

If

they

are

not

marked

as

such,

they

are

probably

variable

outputs

(see

"About

Variable-Level

Outputs,"

on

Page

8).

Outputs

from

VCRs

are

almost

always

fixed.

Hint:

When

connecting

to

the

fixed

audio

outputs

ofa

VCR,

remember

that

for

the

wireless

system

to

work,

the

VCR

must

be

active.

In

other

words,

turn

the

TV

on

to

the

channel

you

would

normally

use

to

watch

a

videotape

(channel

3 or

4),

turn

the

VCR

on,

then

press

the

TVNCR

button

on

your

VCR

remote

control

one

time

to

make

the

VCR

the

controlling

piece

of

equipment.

At

this

point

whatever

channel

is

showing

on

the

tuner

for

the

VCR

should

be

the

channel

playing

on

the

TlI.

Change

channels

on

the

VCR.

This

configuration

gives

independent

volume

control

through

the

TV

(using

the

TV

remote

control)

and

at

the

headphones.

This

allows

others

in

the

room

to

listen

to

TV

at

volume

levels

they

find

comfortable,

and

you

to

listen

through

the

headphones

at

volume

levels

you

find

acceptable.
