OWNER'S

MANUAL

Congratulations

on

your

choice

of

the

Harman

Kardon

AP2500

Stereo

Preamplifier.

In

order

to

obtain

the

best

performance

from

this

preamplifier,

please

be

sure

to

read

this

owner's

manual

and

use

the

AP2500

only

in

accordance

with

its

instructions.

The

special

features

of

this

unit

include

:

Higher

Fidelity

through

Simplicity

The

AP2500

is

an

extreme

expression

of

higher

fidelity

through

attention

to

the

basics

of

preamplifier

design

and

construction.

All

of

the

key

elements

that

produce

sound

have

been

meticulously

designed

to

have

the

lowest

noise

and

distortion,

widest

bandwidth

and

highest

isolation

of

any

product

of

its

kind.

All

of

the

features

that

are

rarely

used

and

tend

to

complicate

the

audio

signal

path

have

been

deliberately

deleted.

The

resulting

performance

is

a

unique

combination

of

exceptional

sound

quality

and

value.

Ultrawide

Bandwidth

The

bandwidth

of

this

unit

is

exceptionally

wide

and

is

independent

of

negative

feedback.

This

improves

transient

accuracy

and

phase

linearity.

Low

Negative

Feedback

This

unit

has

been

designed

to

have

low

distortion

and

wide

bandwidth

without

high

negative

feedback.

This

further

improves

its

dynamic

accuracy.

Discrete

Component

Circuitry

In

order

to

achieve

the

above

goals,

all

discrete

electronic

circuitry

has

been

employed.

No

available

integrated

circuits

could

provide

this

high

level

of

performance.
