INTRODUCTION

The

Arcam

Alpha

9

integrated

amplifier,

is

derived

from

the

highly

successful

Arcam

Delta

290

model.

It

is

rated

at

70

watts

per

channel

into

8

ohms.

The

Alpha

9

is

extremely

versatile

and

suitable

for

both

conventional

and

Audio

Visual

(home

cinema)

based

systems.

It

can

be

used

as

an

integrated

amplifier

or

as

a

preamplifier

to

drive

external

power

amplifiers.

The

preamp

out

sockets

also

allow

the

addition

of

an

Alpha

9P

power

amplifier

to

give

a

true

bi-amplified

system.

In

this

configuration

the

power

amplifiers

within

the

Alpha

9

integrated

amplifier

are

retained

to

drive

the

loudspeakers’

treble

units

whilst

using

the

Alpha

9P

to

drive

their

bass/midrange

units.

In

addition

to

this

the

Alpha

9

integrated

amplifier

can

also

be

used

as

a

stand

alone

power

amplifier

via

its

“power

amp

in”

sockets

or

combined

with

suitable

loudspeakers

and

an

AV

processor,

such

as

the

Arcam

Xeta

2,

to

form

a

very

high

performance

home

cinema

system.

The

Alpha

9P

is

a

matching

70

watts

per

channel

power

amplifier

designed

to

complement

the

Alpha

9

integrated

amplifier.

It

offers

an

easy

upgrade

path

for

owners

of

the

Alpha

9

integrated

amplifier

(or

the

Delta

290

integrated

amplifier)

to

provide

a

bi-amplified

system.

It

may

also

be

used

with

Arcam’s

Alpha

7

and

8

integrated

amplifiers,

either

as

a

simple

power

booster

or

as

part

of

a

high

performance

bi-amplified

system.

It

can

be

used

with

almost

any

preamplifier

and

is

ideal

for

upgrading

both

hi-fi

and

Audio

Visual

systems.

This

manual

is

your

mains

supply

voltage

agrees

with

the

voltage

setting

indicated

on

the

rear

panel

of

the

unit.

■

If

your

mains

supply

voltage

is

different,

consult

your

Arcam

dealer.

MAINS

SAFETY

■

This

product

is

normally

supplied

with

a

moulded

mains

plug

already

fitted

to

the

lead.

If

for

any

reason

the

plug

needs

to

be

removed,

It

must

be

disposed

of

immediately

and

securely,

as

it

is

a

potential

shock

hazard

when

inserted

Into

a

mains

socket.

NOTICE

FOR

U.K,

OWNERS

ONLY

■

If

the

plug

is

removed

then

the

remaining

lead

must

be

rewired

as

follows:

■

The

blue

wire

must

be

connected

to

the

terminal

which

Is

coloured

blue

or

marked

with

the

letter

N.

■

The

brown

wire

must

be

connected

to

the

terminal

which

is

coloured

brown

or

marked

with

the

letter

L.

■

The

green

and

yellow

wire

must

be

connected

to

the

terminal

which

is

coloured

green

and

yellow,

or

marked

with

the

letter

E

or

the

safety

earth

symbol.

■

When

replacing

the

fuse

in

the

supplied

moulded

mains

plug,

the

integral

fuse

holder/cover

must

always

be

refitted.

Use

a

5

amp

fuse.

SAFETY

international

electrical

safety

standard.

MAINS

SUPPLY

CONNECTIONS

®

Insert

the

lEC

line

socket

of

the

mains

lead

fully

into

the

power

inlet

on

the

rear

panel.

Connect

the

other

end

to

your

mains

supply.

CAUTION:

Your

Alpha

9

and

Alpha

9P

generate

heat

when

in

use,

particularly

at

higher

volumes.

It

is

therefore

most

important

never

to

obstruct

the

ventilation

slots

on

the

top

and

bottom

of

the

unit

as

this

will

cause

overheating.

If

the

temperature

of

the

internal

heatsinks

rises

above

a

safe

level,

then

a

thermal

cut

out

inside

the

amplifier

will

operate.

The

POWER

LED

on

the

front

panel

will

turn

amber

and

the

output

protection

relays

will

temporarily

remove

the

feed

to

the

loudspeakers.

The

system

will

reset

itself

as

the

heatsinks

cool

down.

Please

note

that

under

certain

conditions

it

is

possible

for

the

Alpha

9

or

Alpha

9P's

thermal

cut

out

to

operate

when

playing

music

at

very

high

levels.

This

might

for

example

happen

when

continuously

playing

heavily

compressed

rock

music

"flat

out"

into

low

impedance

(4-6

ohm)

speakers.

If

this

happens

to

you,

the

cure

is

to

turn

the

volume

down

slightly

and

ensure

the

amplifier

is

properly

ventilated.

It

is

Important

to

point

out

that

when

playing

a

heavily

recorded

CD

it

is

possible

to

drive

the

Alpha

9

at

full

power

despite

the

fact

that

the

volume

control

is

only

at

10

or

11

o'clock.

This

Is

because

of

the

high

output

voltage

from

a

CD

player.

However

the

Alpha

9

also

has

to

be

capable

of

giving

full

power

output

from

much

lower

level

sources,

such

as

tuners

and

cassette

decks.

Using

these

sources,

the

volume

control

setting

will

be

much

higher

before

overload

sets

In.

Warning:

This

apparatus

must

be

earthed.

Please

refer

to

drawing

inside

front

cover.

LOUDSPEAKER

CONNECTIONS

■

The

amplifier

is

fitted

with

BFA

(British

Federation

of

Audio)

loudspeaker

connectors,

which

are

The

BFA

connector

will

accept

spade

terminals,

bare

wires

up

to

4mm

in

diameter

or

a

BFA

plug.

usually

be

identified

by

a

ridge

or

coloured

marking.

Ensure

that

no

stray

strands

are

allowed

to

touch

another

cable

or

the

amplifier's

casing.

This

can

cause

a

short

circuit

and

damage

your

amplifier!

BI-WIRING/BI-AMPING

INSTRUCTIONS

Many

modern

loudspeakers

are

equipped

with

four

connection

terminals.

This

provides

direct

access

to

the

high

frequency

and

low

frequency

filter

networks

and

associated

drive

units

within

the

loudspeaker.

Overall

performance

can

be

enhanced

by

making

use

of

these

separate

connections.

WARNING:

Do

not

make

any

connections

to

your

amplifier

while

it

is

switched

on

and

connected

to

the

mains

supply.

Please

check

all

connections

thoroughly

before

attempting

to

re-connect

the

mains

power

supply.

Always

ensure

that

the

volume

control

on

your

amplifier

is

set

to

a

minimum

before

switching

on.

BI-WIRING

Bi-wiring

uses

four

conductors,

one

for

each

terminal,

to

enhance

dramatically

the

performance

of

your

loudspeakers.

Bi-wiring

eliminates

the

signal

distortion

arising

from

the

low

and

high

frequency

currents

interacting

with

one

another

within

a

single

cable,

as

used

in

conventionally

wired

systems.

HOW

TO

BI-WIRE

YOUR

LOUDSPEAKERS

1.

Remove

the

shorting

links

from

each

of

the

red

and

black

terminal

pairs

on

the

rear

of

your

loudspeakers.

2.

You

will

need

two

lengths

of

loudspeaker

cable

per

loudspeaker

(which

may

be

joined

at

the

amplifier

end)

or

a

suitably

terminated

cable

set

capable

of

being

used

for

bi-wiring

in

one

length.

3.

Connect

the

cables

as

per

diagrams,

dependant

on

your

cable

wiring,

ensuring

correct

polarity

at

all

times.

The

positive

(+)

connections

on

the

right

loudspeaker

must

go

to

the

positive

(+)

connections

on

the

right

channel

of

the

amplifier

and

the

negative

(-)

connections

on

BI-AMPING

The

performance

of

your

system

can

be

further

enhanced

over

that

achieved

with

bi-wiring,

by

extending

the

same

principal

one

stage

further

to

include

separate

amplification

for

the

low

and

high

frequency

speaker

drive

units

as

well

as

separate

loudspeaker

cables.

This

is

known

as

biamplifying,

or

bi-amping

for

short.

To

implement

bi-amping

therefore

requires

four

amplification

channels.

In

practice

this

is

done

by

using

two

stereo

amplifiers;

when

one

of

these

is

an

integrated

amplifier

it

is

best

to

use

this

drive

the

high

frequency

(HF)

units

whilst

the

outboard

power

amplifier

is

used

to

drive

the

low

frequency

(LF)

units.

We

recommend

that

you

use

identical

amplifiers

to

avoid

potential

imbalances

in

sonic

performance

and

sensitivities.

The

Alpha

9/9P

combination

is

ideal,

as

is

the

Delta

290/290P.

It

is

however

possible

to

mix

amplify

a

pair

of

bi-wireable

loudspeakers.

This

will

reap

substantial

improvements

in

sound

quality

if

the

following

advice

is

observed.

■

Always

switch

on

the

Alpha

9

and

allow

It

to

stabilise

(indicator

light

turns

green)

before

switching

on

the

Alpha

9P.

■

The

Alpha

9

and

Alpha

9P

power

amplifier

are

placed

on

separate

shelves.

Stacking

the

units

on

top

of

each

other

will

reduce

the

sound

quality

slightly.

It

will

also

reduce

ventilation

and

consequently

the

continuous

power

handling

capability.

■

The

existing

Alpha

9

should

be

used

to

drive

the

loudspeakers'

HF

(high

frequency)

units.

The

new

Alpha

9P

Is

utilised

for

the

LF

(bass)

drivers,

as

shown

in

the

wiring

diagram

below.

■

At

the

end

of

a

listening

session

the

Alpha

9P

should

always

be

turned

off

first.

■

High

quality

interconnect

cables

should

be

used

between

the

Alpha

9

and

Alpha

9P.

■

The

use

of

high

quality

interconnect

and

speaker

cables

in

your

system

is

essential

to

obtain

good

sound

quality.

Contact

your

dealer

or

Arcam

for

further

details

and

recommendations.

Note:

The

second

set

of

speaker

terminals

(SP2)

on

both

units

can

be

used

to

drive

extra

loudspeakers

in

other

rooms

provided

the

impedance

of

these

are

8

ohms

or

more.

-

WARNING

-

Ensure

that

the

TERMINAL

LINKS

ARE

REMOVED

on

the

loudspeakers

before

switching

on

the

amplifiers.

Failure

to

do

this

could

cause

damage

to

one

or

both

amplifiers

and

this

is

not

covered

under

the

warranty.
