/THE

BALANCE

AND

/

LEVEL

PARAMETERS

Since

all

of

the

GEP50

effects

have

the

same

BALANCE

and

OUT

LVL

(Output

Level)

parameters,

we'll

describe

them

here

and

leave

them

out

of

the

descriptions

of

each

effect

that

follow.

BALANCE

and

OUT

LVL

are

normally

the

last

two

para-

meters

called

in

an

effect's

parameter

list.

Effect/Direct

Signal

Balance

(BALANCE):

0

—

100%

This

parameter

adjusts

the

balance

between

the

direct

sound

of

your

instrument

(or

other

source)

and

the

effect

signal.

At

100%

only

the

effect

sound

is

delivered

from

the

GEP50

outputs,

while

at

0%

only

the

direct

sound

is

output.

At

a

setting

of

50%,

the

direct

and

effect

sounds

are

output

in

approximately

equal

proportions.

Effect

Output

Level

(OUT

LVL):

0

—

100%

This

parameter

sets

the

output

level

of

the

effect.

This

is

particularly

handy

for

matching

the

levels

between

effects

when

setting

up

an

effect

sequence

for

a

live

performance.

The

distortion

programs

are

capable

of

producing

an

extremely

broad

range

of

distortion

sounds

that

are

ideal

for

virtually

all

guitar

styles.

The

various

presets

provide

a

range

of

immedi-

ately

useful

distortion

sounds.

Distortion

(DISTORTION):

0

-

100%

This

parameter

sets

the

"degree"

of

distortion

produced.

A

setting

of

0

produces

a

perfectly

clean

sound,

while

a

setting

of

100

produces

the

most

heavily

distorted

sound.

Treble

Boost/Cut

(TREBLE):

-12

—

+12

dB

Permits

boosting

or

cutting

the

high

-frequency

range.

Minus

settings

(e.g:

-6

dB)

reduce

the

high

-frequency

content

of

the

sound,

while

plus

settings

(e.g:

+6

dB)

emphasize

the

high

-

frequencies.

Midrange

EQ

Frequency

(MID

FRQ):

500

-

4,000

Hz

Sets

the

mid

-frequency

range

to

be

boosted

or

cut

using

the

next

parameter:

MID

GAIN.

Midrange

EQ

Gain

(MID

GAIN):

-12

--

+12

dB

Boosts

or

cuts

response

in

the

frequency

range

set

by

the

MID

FRQ

parameter

(above).

A

setting

of

0

produces

no

boost

or

cut.

Minus

settings

(e.g:

-6

dB)

cut

response

in

the

selected

frequency

range,

while

plus

settings

(e.g:

+12

dB)

boost

response.

Bass

Boost/Cut

(BASS):

-12

—

+12

dB

Permits

boosting

or

cutting

the

low

-frequency

range.

Minus

settings

(e.g:

-6

dB)

reduce

the

low

-frequency

content

of

the

sound,

while

plus

settings

(e.g:

+6

dB)

emphasize

the

low

-

frequencies.

Trigger

Level

(TRG.

LEVEL):

1

—

100

Determines

the

amplitude

of

the

input

signal

required

to

trigger

the

distortion

effect.

This

parameter,

in

conjunction

with

the

RELEASE

parameter

below,

functions

effectively

as

a

noise

gate

to

cut

out

hiss

and

noise

when

an

input

signal

is

not

present.

TRG

LEVEL

should

be

set

so

that

the

effect

is

activated

only

when

a

note

is

played

on

the

instrument

used.

Release

Time

(RELEASE):

5

-

32000

milliseconds

Determines

the

amount

of

time

it

takes

for

the

distortion

gate

to

close

after

the

input

signal

drops

below

the

trigger

level.

Proper

setting

of

the

RELEASE

parameter

is

essential

to

allow

a

natural

decay

of

the

source

instrument

sound.
