FEATURES

FEATURES

■

Ultrawide

Bandwidth

The

bandwidth

of

this

unit

is

exceptional

ly

wide

and

inde-

pendent

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.

■

Dual

RIAA

Phono

Equalization

The

phono

section

employs

Harman

Kardon's

unique

dual

RIAA

equalization

circuitry.

RIAA

equalization

is

used

in

both

the

open

-loop

and

closed

-loop

signal

path

(with

and

without

negative

feedback).

This

permits

the

application

of

constant

low-level

negative

feedback

throughout

the

audio

range.

■

Discrete

Component

Circuitry

In

order

to

achieve

the

above

goals,

al

l

discrete

electronic

circuitry

has

been

employed.

All

avai

lable

integrated

cir-

cuits

could

not

provide

this

high

level

of

performance.

■

Moving

Coil

Cartridge

Amplifier

A

high

sensitivity,

low

noise

ampl

ifier

is

provided.

This

permits

the

direct

input

of

most

moving

coil

cartridges.

■

Capacitance

Trim

Selector

This

feature

enables

precise

impedance

matching

between

moving

magnet

type

cartridges

and

the

phono

circuitry.

The

widest,

flattest

frequency

response

possible

can

be

obtained

from

any

high

qual

ity

phono

cartridge.

■

Switchable

Bass

and

Treble

Turnover

points

Switchable

turnover

points

vary

the

effects

of

the

bass

and

treble

controls

over

the

upper

bass,

midrange

and

lower

treble

frequencies.
