and

before

Gain

Switch

The

GAIN

Switch

changes

both

the

input

sensitivity

(amount

of

amplification)

and

the

input

overload

level

of

the

preamplifier

circuitry.

The

"Normal"

position

provides

an

input

sensitivity

that

it

typical

of

other

high

quality

integrated

amplifiers

and

preamplifiers.

This

mode

has

an

input

overload

level

of

2.5

Volts,

which

is

high

enough

to

use

with

nearly

any

high

fidelity

source.

The

"-10dB"

position

both

decreases

the

input

sensitivity

and

increases

the

input

overload

level

by

10dB

(approximately

3

times).

This

allows

very

strong

input

signals

to

be

amplified

without

distortion.

It

also

provides

a

wider

dynamic

range.

Some

listeners

may

prefer

this

position

for

listening

to

CD

players,

for

example.
