RCA

Input

and

Pass-Thru

Output-

These

RCA

jacks

allow

for

a

normal

Left

and Right channel signal input. Simplyconnect

to

the

source

unit

using

RCA

type audio cables, keeping them away from

power

wiring wherever possible.

On

the 4 channel

amplifiers

"Front"

and "Rear"inputjacks are present.

The

"Pass-Thru" output

allows

the signal

to

pass on

to

other

amplifiers.

The

Pass-Thru

output is unaffected by the onboardcrossover.

Input

Gain

Adjustment-

This control matches the preampstage

of

the Diamond

amplifier

to

your

source unit. This

is

NOT

a volume

control.

The

range is between 150mVand

5V.

High Level Inputs (0300.2, 0300.4, 0400.1) -This plug {included} is

for

use when the source

unit

does not have an

RCA

output.

Although this is a

popular

method

of

connecting a factory

car

stereo, some systems mayrequire additional adaptors.

The

far

left

side

of

the

plug

is the LEFTchannel; the

far

right

side is

for

the Right channel.

The

wire in the middle is

for

chassis

ground

ONLY

if

the system is experiencing excessive noise problems.

Crossover Selection Switch -This switch allows you

to

select the crossover.

Use

High Pass

for

midrange

or

high frequency

speakers.

Use

Low

Pass

for

subwoofers. In the OFFposition, the crossover

adjustment

knob has no effect.

The

D600.1

and

D1000.1

are onlyavailable

as

Low

Pass.

Crossover

Adjustment-

Use

this adjustment

to

select the crossover point.

Remember

that

your

choice

will

be

directed

to

High

Pass

or

Low

Pass depending upon the position

of

the adjacent switch.

Sub-Sonic

Adjustment

(0400.1, 0600.1,

01000.1)-

This control

allows

you

to

remove the unwantedsub-sonic frequencies

below

the tuning frequency

of

a

ported

enclosure. This helps

to

protect

the woofer from

over

excursion. (D400. 1Switchable (OFF/ON})

(D600.1, D1000.1, Variable From 16-60Hz}

Phase

Adjustment

(0400.1, 0600.1,

01000.1)-

This control allowsyou

to

adjust the "phase"so

as

to

align the subwooferin

"time"

to

the mids

and

tweeters. This is selectable

for

0

or

180

degrees. This is EXTREMELY useful

to

get the best and

MOST

bass out

of

your

system.

Bass Boost- This control adds 0

to

+12dB

of

boost

at

the frequency

that

the Bass Boost Frequency is

set

to.

Be

cautious when

adding boost

to

some

subwoofer

systems

as

theymaynot

be

able to handle the additional

low

frequency boost. In the

OdB

position,

no bass boost is added.

Bass Boost Frequency (0600.1,

01000.1)-

This is

to

adjust the specific frequency that

your

Bass Boost Control

will

boost (30Hz

-125Hz}.

Master/Slave

RCA

Input/Output

(0600.1,

01000.1)-

This

RCA

Input/Output is used in conjunction with the Master/Slave switch.

This allows one remote level control

to

control

multiple

amplifiers

(amplifiers

must

be

the same model}. This eliminates noise

and

the need to adjust the slave amplifier{s}, while increasing efficiency.

Master/Slave

Switch-

This

switch

is usedwhen connecting

multiple

amplifiers.

One

amplifier

should

be

assignedthe MASTER and

the other(s}

should

be

set

to

Slave. This

will

cause

all

of

the

amplifers

set

to

Slave

to

function identical

to

the MASTER amplifier.

One

remote level control knob

pluged

into the

amplifier

with the MASTER switch selected

will

now

control both amplifiers.

Remote Level

Adjustment

(0400.1, 0600.1, 01000.11- This

port

is

for

the remote level control (included}.

The

control is intended

to

allow

the

user

to

control the level

of

gain up

to

the maximum

adjustment

level

set

on the amplifier.

The

control does

not

add

additional boost,

it

only

attenuates the setting that is fixed

at

the

amplifier's

control panel.

Status LED's -These

lights

indicate when the

amplifier

is powered up

normally

and

when there is a protection fault. See the

'"Troubleshooting" section

for

details on what these useful indicators can

tell

you

if

there's a problem.

Power

Input

Connections -These connections are

for

input power, chassis ground, and remote turn-on.

Use

a

minimum

of

4

gauge wiring

for

power

and

ground

connections.

The

terminals

will

handle up

to

4 gauge.

Be

sure anywiring thatpasses through

metal

has a

grommet!

Power

Fuses (Except

01000.1)-

Standardautomotive type

ATC/ATO

fuses are usedon DiamondSeries Amplifiers. Always replace

with the correctfuse size. Neverinsert fuses

of

higher

values. Doing

so

will

voidthe

warranty

of

your

Diamondamplifier. Also include

a main fuse

at

the connection to the vehicle

battery

within

18

inches (45.7

mm}

of

the positive

battery

post. It is also

important

to

upgrade the connection between the negative

battery

post and the chassis

of

the vehicle. This

greatly

reduces possibilities

of

weak

electrical

"links"

in

the circuit.

SpeakerOutput

Terminals-

Connect

your

speakers

to

these terminals. Stereo connections are made

as

labeled. Bridgedconnections

use the

LEFT+

and

RIGHT-

as

the two connection,s.

The

2 and 4 channel

amplifiers

will

perform

into 2

Ohm

stereo loads

or

4

Ohm

bridged

loads.

DO

NOT

run

2

Ohm

bridgedloads on these

amplifiers!

The

D600.1 and D1000.1, are the only

amplifiers

in the

series capable

of

driving a load

as

low

as

1Ohm.

Strapping

Amplifiers

to6oo.1,

o1ooo.11

Your

new

Diamond Audio

amplifiers

have the unique

ability

to

combine

or

"strap"

either

two

D600.1's

or

two

D1

000.1's

together

to create one

extremely

powerful

channel.

You

cannot

strap

a D600.1 and a

D1

000.1 together.

You

must

only connect two

identical

amplifiers.

When you

strap

two Diamond Audio

amplifiers

together,

you get the added benefit of being able to use one remote level

control

to

control

both

amplifiers.

The

Importance

of

Pre-Planning

This section focuses on some of the considerations

for

installing

your

new Diamond Audio amplifier.

Pre-planning

your

audio system layout and best

wiring

routes

will

save installation time. When decid-

ing

on

the layout of

your

new components,

be

sure

that

each component

will

be

easily accessible

for

making

adjustments.

CAUTION:

lf

you

feel unsure about installing this system yourself,

have

it installed

by

a qualified techni-

cian.

CAUTION:

Before installation, disconnect the

negative(-)

battery

terminal

to prevent damage to the

unit, fire

and/or

possible injury.

Before

beginning

any installation, follow

these

sensible guidelines:

1)

Be

sure to carefully read and understand the

instructions

before

attempting

to

install

the amplifier.

The

instructions

can only help

you

make the installation successful.

2)

For safety, disconnect the negative lead from the

battery

prior

to beginning the installation. It

will

keep any unintended

short

circuits from damaging vehicle electronics

during

installation of the

amplifier.

3)

For easier assembly, run

all

wires

prior

to mounting

your

amplifier

in place.

4)

Route

all

of the

RCA

cables close

together

and away

from

any high

current

wires

or

vehicle

com-

puters. This

will

greatly

minimize

the chances of unwanted noise.

5)

Use high

quality

connectors

for

a reliable installation and to

minimize

signal

or

power loss.

6)

Think before you

drill!

Be

careful not to cut

or

drill

into gas tanks, fuel lines, brake

or

hydraulic

lines, vacuum lines,

or

electrical

wiring

when

working

on any vehicle.

7)

Never run

wires

underneath the vehicle. Running the

wires

inside the vehicle provides the best

protection.

8)

Avoid

running

wires

over

or

through

sharp edges.

ALWAYS

use

rubber

or

plastic

grommets

tO

protect any

wires

routed through metal, especially the

firewall.

9)

ALWAYS

protect the

battery

and

electrical

system

from

damage

with

proper

fusing.

Install

the ap-

propriate fuse

holder

and fuse

on

the +

12V

power

wire

within

18

inches (45.7 mm) of the positive

battery

terminal.

This is

for

protection of the wire

running

through

the vehicle.

1

0)

When grounding to the chassis of the vehicle, scrape

all

paint from the

metal

to ensure a good,

clean ground connection. Grounding connections should

be

as

short

as possible, yet

be

adequately

connected to

metal

that

is welded to the main body,

or

chassis ofthe vehicle.

Do

not use seat bolts,

trunk

hinges,

or

poorly joined

metal

for

grounding points.

Mounting

Locations

Engine

Compartment

Never

mount

this

unit

in

the

engine

compartment.

Mounting

the

unit

in

the

engine

compartment

will

void

your

warra:-~ty.

Trunk

Mounting

tre

amplifier

vertically

will

provide adequate cooling of

the

amplifier.

If you

will

be

mounting

it to an existing panel,

be

sure

it's not prone to excessive

vibration

(such as

mounting

to

the

back of a

subwoofer

enclosure). Excess

vibration

is not

recommended

for

electronic

products,

amplifiers

included.

Mounting

the

amplifier

flat

on

the

floor

of

the

trunk

will

provide the best cooling, however

be

cautious

not to deposit baggage and

other

items

over

the

top of

the

amplifier.

Mounting

the

amplifier

upside

down to

the

rear

deck

of

the

trunk

will

NOT provide adequate heat dissipation and

will

severely affect

the

performance

of

the

amplifier

and is not

recommended.

Passenger Compartment Mounting

Mounting

the

amplifier

in

the

passenger

compartment

will

work

as long as you provide a

sufficient

amount

of

air

for

the

amplifier

to cool itself. If you are going to

mount

the

amplifier

under

the

seat

of

the

vehicle, you

must

have at least 1 inch (2.54cm) of

air

gap around

the

amplifier's

heatsink.

Mounting

the

amplifier

with

less

than

1 inch (2.54cm) of

air

gap

around

the

amplifier's

heatsink

in

the

passenger

compartment

will

not provide

proper

cooling and

will

severely affect

the

performance

of

the

amplifier

and is not

recommended.

Vehicle

Electrical

System

Requirements

Amplifiers

(regardless

of brand name)

will

put an increased load on

the

vehicle's

battery

and

charging

system.

OAT

recommends

checking

your

alternator

and

battery

condition to

ensure

that

the

electrical

system has enough capacity to handle the increased load

of

your

stereo system.

Original

equipment

electrical

systems

which

are in good condition

should

be able to handle

the

extra load of any

OAT

ampli-

fier

without

problems,

although

battery

and

alternator

life can

be

reduced depending on

your

individual

listening

habits.

To

maximize

the

performance

of

your

amplifier,

we

suggest

the

use of a reserve

power

"Stiffening

"capacitor.

Wiring

the

Amplifier

CAUTION:

Avoid

running

power

wires

near

the

low

level

input

cables, antenna,

power

leads, sensitive

equipment

or

harnesses.

The

power

wires

carry

substantial

current

and could radiate noise into

the

audio system

through

the

audio cables.

1)

Plan

the

wire

routing

as

described

in

the

"Importance

of

2)

cessories,

especially

electric

motors.

This is done to prevent

coupling

the

noise

from

radiated

electrical

fields

into

the

audio

signal.

When feeding

the

wires

through

the

firewall

or

any

metal

barrier,

protect

them

with

plastic

or

rubber

grommets

to prevent

short

circuits.

Leave

the

wires

long at

this

point to adjust

for

a precise fit

at a

later

time.

Prepare

the

7) Securely

mount

the

amplifier

to the vehicle

or

amp

rack. Be

careful

not to

mount

the

amplifier

on

cardboard

or

ALL

Diamond mono block amplifierscome with two positive speakerterminals and two negative speaker

terminals. This makes it easier to connect

multiple

woofers to one amplifier. Inside of the

amplifier

the two positive

terminals

are connected.in parallel and the two negative

terminals

are connected

in parallel. This means that if one 4 ohm woofer is connected to each

Connecting Multiple Speakers

If you

must

connect

more

than

one

speaker

per

channel,

there

are

two

methods

in which to do so:

Series

or

Parallel.

Parallel

connections are

harder

on

the

amplifier

than series connections, as the

total

impedance

is

lower

compared

to

driving

a

single

speaker,

and

the

amplifier

must

produce

more

current

to drive

them.

Installing

the

Remote

Level

Controller

The 0400.1, 0600.1,

&

D

1000.1

come packaged with a remote level control. This allows

you

to

control the level

by

attenuating the amplitude

or

increasing

(up

to the maximum set-point)

of

the amplifier's input gain control. This control does not add additional gain,

it

simply allows

you

to control the level to suit your tastes.

1)

Locate a position

in

the front

of

the vehicle where this will be easy to reach. Common

locations

are

on,

in,

or

under the dash,

in

the

center

console, or

in

the glove

box.

2)

To

mount the unit, attach the bracket using the supplied hardware to your chosen loca-

tion.

3) Route the telephone style data cable back to the amplifier location and connect into the

remote level port. Test

to

make

sure

the operation

is

functioning.

Get

Ready

to

Listen! -

Perform a final check

of

the completed system wiring

to

ensure

that all connections are

accurate. Check all power and ground connections for frayed wires and loose connections

which could

cause

problems. Install in-line fuse

near

batteryconnection at this time. Prepare

to make

some

adjustments

to

fine tune your audio system for optimum performance.

Adjustment

of

Input

Gain

To

adjust the gain setting, turn the amplifier gains all the way down (counterclockwise).

Turn the source unit volume

up

until distortion is audible and then turn

it

down a bit until

the distortion is inaudible. This will be

NEARLY

full volume

on

most source units,

perhaps

one

or

two "clicks" down from maximum volume. Next, increase the amplifier gain setting

until adequate volume

is

achieved.

NOTE:

Ideal signal to noise and dynamic range are achieved with the gain at minimum. Most

users

find

adequate gain and volume

is

achieved at about halfway

in

the adjustment range.

Avoid

setting the amplifier gain very

hi

'

gh

as

noise and distortion will increase significantly.

14

Adjustment

ofBuilt-In

Crossover

(All

Models}

Pldcing the switch in the

FULL

position sets the

amplifier

to Full

Range.

This setting allows

ALL frequencies to pass to the speakers. (Not available

on

0600.1, & 01000.1). Placing the

switch in the

HP

or

LP

position activates the crossover.

Placing the switch in the

HP

position sets the

amplifier

to the

High

Pass

mode, enabling

frequencies

above

the cutoff point to pass.

Placing the switch in the

LP

position sets the

amplifier

to the

Low

Pass

mode, enabling

frequencies below the cutoff point to pass.

Turn the crossover

adjustment

knob

all

the way down. With the system playing,

turn

the

crossover

adjustment

knob

up

slowly

until

the desired crossover point is achieved.

Adjustment

of

the

Bass

EQ

(0400.1, 0600.1, & 01000.1}

After

setting the input gain adjustment and crossover, you may choose to add a small

amount

of

··boost"

in the

Low

frequency region. The bass boost frequency is variable

between 30Hz and 125Hz (0600.1, & 01000.1

ONLY).

Remember that the Bass Boost

feature

will

not fix a poorly designed subwoofer enclosure

or

subwoofers that

didn't

sound

good to begin with.

1)

Make sure any

bass

EQ

or

low

frequency equalization

from

the source unit is set to

OFF

or

FLAT.

If you have

other

outboard signal processors

with

equalization, you should use

those to add boost

first

and

Leave

the

amplifier's

bass boost alone.

2)

While playing the same musical selections used during the gain setting process, slowly

increase the

Level

of the Bass

EQ.

You

should

be

able to notice a demonstrable change

between 0 and +12dB. If you

do

not notice much difference, then

it

will

not serve any

benefit to increase the boost further.

3)

If the boost has audible benefits

without

adding appreciable distortion,

find

a level that

suits

your taste. Remember: it's much easierto construct the right subwoofer enclosure

for

your Listening preferences than relying

on

a bass boost control to do the job!

Remember

that

the Bass

EQ

feature has

an

optional dash mounted control included

with

the

amplifier

that

will

function as

an

attenuator between the

maximum

Level

set at the

amplifier

and

OdB

of attenuation. It

will

not add boost beyond the

Level

you choose at the amplifier.

Troubleshooting

It's imperative thatyou read the manual fullyto eliminate the possibilityof mistakes made from

assumptions about how you

"think"

the

amplifier

might

work

versus how it's recommended

to

be

installed. If the

amplifier

does not appear to

be

working, check obvious things

first

such

as

blown fuses, incorrect

wiring

configurations, poor

or

Loose

connections, crossover,

Bass

EQ,

and gain controls set incorrectly, etc. These

elements

are the most common cause

of

initial

problems, so take your time and double check

all

of

yourwork

before assuming

there's a serious problem.
