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

you

time

later

on.

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

SMPTE/EBU

Time

Code

SMPTE

is

an

acronym

for

the

Society

of

Motion

and

Television

Engineers.

The

SMPTE

Time

Code

(C98.12:

time

and

control

code

for

video

and

audio

tape

for

525/30

television

system)

was

defined

in

1970,

and

it

is

now

accepted

as

a

universal

standard.

This

reference

is

to

an

80-bit

digital

code

developed

by

SMPTE

and

used

to

designate

the

exact

location

in

hours,

minutes,

seconds

and

frames

(24

frames/sec.

for

film

or

30

frames/sec.

for

video)

on

a

film,

video

tape,

or

audio

tape.

Suitable

equipment

can

synchronize

("lock

up”)

two

or

more

machines

by

using

the

SMPTE

time

code

recorded

on

each.

SMPTE.

European

Standard,

that

refers

to

25

frames

per

states

the

EBU

(abbrev.

for

European

casting

Union)

time

code

when

it

is

especially

necessary

to

distinguish

from

the

USA

Standard

with

30

frames

per

second.

A

time

code

generator

is

used

to

record

SMPTE

code

onto

one

track

of

the

tape.

A

time

code

controller

can

then

read

the

code

from

two

or

more

tape

machines,

and

by

also

servo-controlling

the

reel

motors

of

those

ma-

chines,

bring

them

to

specifiec

cue

points.

A

time

code

synchronizer

further

controls

the

capstan

motors

to

keep

both

of

the

tape

machines

running

synchronously.

These

techniques

can

be

used

to

obtain

more

tracks

for

recording

(two

or

more

audio

machines

“locked

up”

to-

gether),

to

mix

audio

signals

in

with

video

or

film

images,

to

make

complex

edits

by

transferring

material

from

one

or

more

audio

machines

to

another,

and

so

forth.

Connecting

a

Synchronizer

to

the

TASCAM

TSR°8

-

Connection

between

the

ES-50

synchronizer/ES-51

edit

controller

and

the

TSR-8

is

a

plug-and-go

pro-

position.

Pre-wired

interface

cables

needed

are

available

from

TASCAM.

The

TASCAM

TSR-8

provides

signals

to

the

synchro-

nizer

(via

the

ACCESSORY

“1”

connector)

which

indicate

its

speed,

the

direction

of

the

tape

travel,

and

a

reference

power

supply.

Also,

tally

signals

indicating

the

TSR-8’s

mode

(PLAY,

F.FWD,

REW,

STOP)

are

given

to

the

synchronizer

so

it

knows

the

current

transport

status.

Inputs

on

the

same

ACCESSORY

‘‘1”’

connector

are

provided

for

status

commands

from

the

synchronizer

(PLAY,

F.FWD,

REW,

STOP,

REC,

LIFTER

CONT).

Also,

there

is

an

input

for

a

capstan

drive

reference

frequency

signal

from

the

synchronizer

so

that

the

actual

record/play

speed

can

be

varied

to

maintain

synchronization.

For

assignment

see

page

12.

The

TSR-8

will

also

operate

satisfactorily

with

a

variety

of

other

manufacturers’

synchronizer/controllers.

The

manual

for

these

products

should

provide

you

with

enough

interface

information

for

use

with

the

TASCAM

tape

machines.

SETTING

THE

RECORD

LEVEL

The

TSR-8

does

not

utilize

its

own

controls

for

setting

the

volume

or

“level’’

of

the

signal

to

be

record-

ed.

Therefore

the

recording

level

is

adjusted

on

the

mixer.

The

basic

procedure

for

setting

the

record

level

is as

follows:

1.

Consult

your

mixer

manual

for

information

about

setting

its

Input

Trims,

Faders,

EQ’s

and

other

controls

that

have

an

effect

on

the

output

level

of

the

mixer.

Set

these

controls

to

their

nominal

levels

on

the

mixer.

2.

Switch

power

on

to

the

About

Punching

In

Setting

in

and

out

points:

For

both

musical

and

technical

reasons,

when

punching

in

or

out

of

a

track,

you

must

select

points

that

are

“in

the

clear”,

i.e.,

in

the

pauses

between’

phrases

or

notes.

It

sounds

unnatural

and

makes

the

insert

noticeable

if

you

record

a

new

note

before

the

old

one

has

ended,

or

are

holding

a

note

as

you

punch

in

or

out.

For

this

reason,

some

session

players

leave

a

beat

or

two

of

silence

between

passages

they

might

want

to

edit

later.

Making

inserts

well

requires

some

practice.

Many

engineers

count

bars

and

beats

to

keep

track

of

the

punch

in

and

out

points

and

hit

them

on

cue.

Because

of

the

spacing

between

the

erase

and

record

heads,

you

may

need

to

anticipate

your

———

ena

in/out

points

by

a

fraction

of

a

second

for

extremely

tight

cues

though

the

gapless

operation

and

high

speed

of

the

TSR-8

makes

it

much

easier.

External

computer

punching:

If

you

need

insert

points

that

are

consistently

repeatable

within

1/30th

of

a

second,

you

may

want

to

control

the

TSR-8

by

an

external

computer

device.

With

this

method,

track

8

is

recorded

with

SMPTE

time

code

and

punch-in/out

points

are

entered

into

the

TSR-8

via

the

serial

connec-

tor

on

the

back

panel.

The

procedure

is

similar

to

the

TSR-8’s

built-in

AUTO

IN/OUT

function

but

more

accurate

because

the

computer

is

reading

a

reference

actually

recorded

on

tape

instead

of

tach

pulses

gener-

ated

by

the

movement

of

the

tape

reels.

Level

matching:

No

matter

how

carefully

you

set

your

punch

points,

if

the

inserted

material

is

louder,

softer,

or

a

different

tone

from

the

original

track,

it

will

be

noticeable.

Set

the

EQ

and

volume

settings

on

your

mixer

the

same

as

they

were

during

the

original

record-

ing.

If

you

make

inserts

immediately

after

recording,

don’t

change

the

instrument

or

mixer

settings

at

all.

Keep

in

mind

that

at

a

certain

point

it’s

better

to

record

the

whole

track

(PING-PONG)

The

recording

capability

of

the

TSR-8

is

not

limited

to

the

eight

tracks.

As

you

progress

with

recording,

you

may

reach

a

point

where

you

need

more

than

eight

tracks

of

material.

This

is

where

Bouncing

—

also

called

Collapsing

or

Ping-ponging

tracks

—

is

invaluable.

Essentially,

bouncing

tracks

consists

of

a

‘‘mini

mix-

down":

taking

tracks

that

have

already

been

recorded,

Tips

About

Bouncing

1.

Before

you

record

over

the

parts

that

have

been

bounced

together,

make

certain

that

you’re

happy

with

the

overall

sound

of

the

bounced

parts,

because

you

won't

be

able

to

change

their

mix

or

punch-in

to

fix

errors,

2.

It

is

possible

to

bounce

tracks

more

than

once,

i.e.,

to

take

a

bounced

track

and-combine

it

yet

again

with

other

material

onto

another

empty

track.

There

are

limits,

however,

just

as

there

are

anytime

you

make

a

copy

of

a

copy.

Eventually

the

sound

will

get

“blurry”

—

treble

will

be

decreased

and

added

dropouts

will

become

more

noticeable.

tracks)

of

the

With

all

recorders,

it

is

possible

to

To

it

to

bounce

Main

parts

program

such

as

and

are

best

can

final

mix.
