terminals

are

terminated

into

speakers

or

into

a

speaker

and

resistive

load.

For

example,

if

you

have

only

one

speaker,

attach

it

to

the

Left

Speaker

Output

connections

and

connect

a

4,

8

or

16

ohm

25

watt

wirewound

resistor

to

the

Right

Speaker

Output

connections.

This

will

assure

proper

loading

of

the

output

stage

and

will

prevent

damage

to

the

output

tubes.

A

more

satisfactory

solution

would

be

to

connect

an

additional

speaker

for

monophonic

listening

instead

of

the

or

16

ohm

resistor.

3rd

Channel

Output:

One

of

the

features

of

the

TA260

is

a

third

channel

output

jack.

This

output

can

be

used

for

a

remote

basic

amplifier

-speaker system

in

addition

to

a

regular

stereo

system,

or

as

a

center

channel

output

for

a

basic

amplifier

-speaker

system

along

with

your

regular

stereo

installation.

In

the

latter

arrangement,

it

serves

to

eliminate

especially

troublesome

hole

-in

-the

-middle

problems

due

to

acoustic

difficulties.

The

third

channel

output

is

one

volt.

The

jack

is

located

just

above

the

rear

panel

on

the

top

of

the

chassis.

Use

up

to

25

feet

of

shielded

lead

equipped

with

standard

phono

plugs

to

connect

the

jack

to

the

third

channel

amplifier

input.

All

of

the

front

-panel

controls

on

the

TA

-260

also

control

the

third

channel

out-

put,

with

the

exception

of

the

Mode

-Blend

Control

and

the

Stereo

Normal

-

Reverse

Switch.

Stereo

Headphone

Output

Jack:

Another

feature

of

the

TA260

is

a

special

jack

on

the

rear

panel

for

plugging

;n

a

set

of

stereo

headphones.

When

the

headphones

are

plugged

in,

the

speakers

are

automatically

disconnected.

The

jack

can

accept

headphones

with

the

same

impedances

as

are

available

for

speakers.

Simply

connect

the

speaker

impedance

selector

leads

to

the

4,

8,

or

16

ohm

terminals

on

the

rear

panel

in

accordance

with

the

impedance

rating

of

your

headphones.

The

headphone

plug

required

for

this

jack

is

the

Switchcraft

Type

230F,

or

equivalent.

It

is

important

to

use

the

right

plug

for

this

purpose

for

proper

operation.

Connecting

The

FM

Antenna:

Due

to

the

exceptionally

high

FM

sensitivity

of

the

TA260,

the

48"

piece

of

wire

supplied

with

the

unit

will

be

sufficient

antenna

for

all

but

the

most

difficult

locations.

One

end

of

this

wire

should

be

stripped

of

insulation

and

attached

to

the

rear

screw

terminal

marked

FM

on

the

Antenna

Terminal

strip

located

on

the

rear

of

the

chassis.

The

other

end

of

this

wire

should

be

extended

horizontally

along

the

cabinet

or

table.

Horizontal

placement

of

the

antenna

wire

provides

proper

polarization

for

optimum

reception.

If

an

outdoor

antenna

is

required

to

"reach"

for

distant

stations,

use

a

folded

dipole

or

Yagi

specifically

cut

for

the

FM

band.

A

homemade

300

ohm

"T"

type

antenna

is

not

satisfactory

and

should

not

be

used

as

a

substitute

for

the

48"

piece

of

wire

supplied

with

the

set.

The

"1"

type

antenna

has

a

tendency

to

pick

up

extraneous

noise.

TV

antennas

are

rarely

satisfactory

as

they

are

not

cut

for

the

FM

band

and

have

a

tendency

to

introduce

ignition

noise

and

other

interference

into

the

tuner

circuit.

They

are

not

recommended

except

under

unavoidable

circum-

stances.

Usually

better

results

can

be

obtained

with

the

48"

piece

of

wire.

When

using

an

outdoor

antenna,

attach

the

300

ohm

lead-in

wire

(twisting

it

4-5

times

for

each

running

foot)

to

the

antenna

terminals

on

the

rear

of

the

TA260

marked

FM

and

G.

Connecting

The

AM

Antenna:

The

AM

swivel

loopstick

antenna

on

the

rear

of

the

TA260

chassis

comprise'

,

all

the

antenna

required

for

normal signal

areas.
