FUNCTIONS

A.

VOLUME:

Adjusts

the

overall

loudness

of

each

individual

channel

regardless

of

the

mode

the

amplifier

is

operated

in

(mono,

stereo,

single

channel).

See

function

9

for

a

description

of

mode

selection.

B.

PRESENCE:

Adjusts

the

amount

of

boost

in

the

upper

high

frequency

range

of

each

individual

channel.

With

the

control

at

minimum

(fully

counterclockwise),

the

frequency

response

of

the

amplifier

is

flat.

C.

OUTPUT

POWER

METERS:

These

meters

indicate

the

power

being

output

to

the

speakers,

one

for

each

channel.

Each

LED

represents

about

3dB

of

sound

level

with

the

first

green

led

representing

a

loudness

level

21dB

below

full

power.

If

all

green

and

yellow

LED's

plus

the

first

red

LED

is

lit,

then

the

peaks

of

the

output

signal

are

soft

-clipping

(this

is

rarely

audible).

If

all

LED's

are

lit,

then

the

amplifier

is

hard

clipping

the

output

signal.

This

is

often

desired

as

distortion

when

used

as

a

guitar

amplifier

but

not

when

used

as

a

bass

or

PA

amplifier

(see

note

D.for

emulation

selection).
