OPERATION/MAINTENANCE

The

guarantee

provided

for

the

TSR-8

has

several

restrictions.

The

TSR-8

will

perform

properly

only

if it

is

adjusted

properly

and

we

guarantee

that

such

adjust-

ment

is

possible.

Setup

is

not

covered

by

Warranty.

If

your

attempts

at

internal

adjustments

are

unsuccessful,

we

will

charge

you

for

readjustments.

Recording

is

an

art

as

well

as

a

science.

As

a

result,

your

finished

product

may

be

judged

more

by

artistic

criteria

than

technical

performance.

Art

is

the

province

of

the

artist

and

TASCAM

can

make

no

guarantee

that

the

TSR-8,

by

/tse/f,

will

assure

the

quality

of

your

work,

Your

skill

as

a

technician

and

your

abilities

as

an

artist

will

be

significant

factors

in

the

results

you

achieve.

The

TSR-8

is

an

exceptionally

reliable

and

versatile

high-performance

8-track,

8-channel

tape

recorder/

reproducer

that

uses

1/2-inch

wide

tape

on

10-1/2-inch

reels

and

operates

at

tape

speed

of

15.

ips

(38

cm/s).

The

TSR-8

features

8-bit

microcomputer

control

for

error-free

tape

operation.

Each

channel

has

its

own

4-bit

microcomputer

to

contro!

record

in/out

circuitry,

allowing

gapless

punch

in

and

out.

The

transport

is

the

“full

servo’’

type:

the

capstan

motor

is

FG

servoed,

and

each

DC

brushless

reel

motor

is

under

control

of

the

8-bit

microcomputer.

The

tension

arms

have

non-contacting

detectors

that

constantly

send

the

micro-

computer

information

on

tape

tension;

the

microcom-

puter

then

adjusts

the

torque

of

each

reel

motor.

The

result

is

smooth

operation,

gentle

tape

handling,

and

the

capability

in

edit

mode

of

moving

both

reels

manually

with

one

hand,

The

TSR-8

has

three

different

external

control

interfaces.

It

has

a

parallel

input

port,

for

connection

to

SMPTE/EBU

based

synchronizers

(such

as_

the

TASCAM

ES-50/51);

and

RS-232C

serial

synchro-

nizers

with

serial

control

(such

as

the

TASCAM

MIDiiZER);

and

a

remote

control

port

for

the

RC-408

remote

control

unit.

The

TSR-8

automatically

senses

when

it

is

under

external

synchronizer

control,

switching

the

servo

system

between

the

external

source

or

its

internal

reference,

Track

8

is

fitted

with

a

Syne

Lock

feature

that

assures

high-quality

time

code

or

FSK

signals

(such

as

those

generated

by

the

TASCAM

MTS-

30

MIDI

Tape

Synchronizer)

can

be

recorded

and

played

back

without

interruption

and

without

dbx

processing.

The

digital

fluorescent

tape

counter

is

tach

driven,

displaying

in

‘minutes

and

seconds

the

distance

the

tape

has

moved

from

a

Zero

reference

point.

The

Rehearsal

and

Auto

In-Out

features

allow

automated

control

of

punch-in

and

out

times

without

external

computer

control.

When

used’

as

the

first

-

stage

of

the

Automated

punch-in/out

operation,

the

Re-

hearsal

feature

programs

the

TSR-8

to

repeat

a

punch-

in/out

sequence

as

many

times

as

you

wish

before

actually

executing

it

on

tape.

The

distance

between

the

erase

and

record

heads

is

automatically

compensated,

for

gapless

‘inserts’.

In

addition

to

a

conventional

return-to-zero

function,

the

TSR-8

is

equpped

with

a

two-point

auto

locator,

which

also

provides

a

repeat

playback

over

the

desired

segment

of

the

tape.

Other

features

include various

EDIT

and

spot

erase

features;

AUTO

INPUT

which

facilitates

communication

between

studio

and

control

room

through

the

tape

returns,

and

more.

This

manual

has

been

designed

to

help

you

as

you

learn

how

to

use

those

features.

Please

read

it

thor-

oughly

and

keep

it

handy

as

you

learn

the

machine.

Taking

the

time

to

use

this

manual

now

will

save

later

may

be

mounted

to

a

such

as

the

TASCAM

to

is

not

Screwing

the

may

cause

INITIAL

CONNECTIONS

CAUTION:

Before

attempting

any

cable

connection,

check

to

make

sure

that

all

the

units

involved

in

your

system

are

turned

off.

When

connecting

the

TSR-8

to

your

system,

use

shielded

cables

that

are

as

short

as

your

situation

will

allow.

We

recommend

low-capacitance

cables

with

quality

connectors,

such

as

the

TASCAM

Pro

Series.

Cheaper

cable

has

less

shielding

and

may

introduce

radio

frequency

interference,

hum

and

noise

into

your

system.

A.

Input/Output

Connections

The

TSR-8’s

inputs

and

outputs

are

handled

by

RCA

jacks

located

on

the

rear

connector

panel

of

the

machine.

Make

the

appropriate

cable

connections

to

the

Program

busses

confirm-

ing

to

the

read-

ings

on

the

recorder.

Route

the

cord

where

there

is

no

on

it,

to

C.

Remote

Control

Connection

and

Computer/

Synchronizer

Interface

On

the

TSR-8's

rear

pane!

are

located

a

REMOTE

CONTROL

connector

and

ACCESSORY

1

and

2

con-

nectors.

The

REMOTE

CONTROL

connection

makes

it

possible

to

connect

the

optional

RC-408

remote

control

unit

to

provide

remote

control

of

all

transport

functions.

The

ACCESSORY

1

connection

is

a

parallel

port,

meaning

transport

controls

are

each

brought

to

a

separate

pin

of

the

connector

for

external

connection

to

the

TASCAM

ES-50

or

other

SMPTE

synchronizers.

The

ACCESSORY

2

is

a

serial

port,

in

which

fewer

wires

carry

digital

messages

to

and

from

the

TSR-8’s

microcomputer

for

external

connection

to

a

controlling

computer

with

RS-232C

serial

data

buss.

It

is

possible

to

hook

up

a

serial-capable

synchronizer

(such

as

the

TASCAM

MIDiiZER)

to

this

port

for

control

and

other

advanced

functions.

For

detailed

information

on

the

use

of

the

ACCESSORY

connections,

consult

TASCAM

or

the

nearest

TASCAM

dealer.
