Indicator

This

Input

A

(Includes

Input

Jack

and

Level

Control)

Input

A

is

an

unbalanced

standard

phone

jack

with

a

nominal

—50dB

sensitivity,

suitable

for low

impedance

microphones

of

150

ohms

to

5

kohms.

The

Input

A

level

control

adjusts

the

mic

preamp

gain

for

optimum inter-

face

with

various

mics

and

for

different

loudness

levels.

0

Input

B

(Includes

Input

Jack,

Level

Control

and

Inst-

Mic

Switch)

Input

B

is

an

unbalanced

standard

phone jack

with

switchable

sensitivity

and impedance.

When

the

adjacent

Inst-Mic

switch

is

in

"Mic"

position,

the

Input

B jack and

Level

control

have

the

same

mic

input

characteristics

as

Input

A.

When

the

switch

is

in

"Inst"

position,

the

sensi-

tivity

changes

to

nominal

—30dB, suitable

for

high

imped-

ance

instrument

pickups,

preamplified

musical

instru-

ments,

and

low

level

tape

recorder

or

mixer

line

outputs.

Both

the

A

and B

inputs

may

be

used

simultaneously;

the

settings

of

the

Input

A

and

Input

B

level

controls

then

determine

the

relative

balance

of

the

two

sound

sources.

Input

Level Display

The

display

monitors

the

signal

level

after

the

E1005

Input

level

controls,

and

has

5

LED's

which

indicate

peak

values

from

—15dB

to

+2dB.

Ideally,

the

Input

level

controls

should

be

set

so

that

the

display

peaks

at

0dB,

with

average

levels

around

—15dB

to

—7dB.

O

Delay Switch

and

Control

The Short

-Long

switch

selects

either

of

two

ranges

of

delay

time,

4

to

9

milliseconds

(Short)

or

65

to

400

milli-

seconds

(Long).

The

adjacent

Delay control

enables

the

actual delay

time to

be

continuously

varied

from

the

minimum

to

the

maximum

within

the

selected

range.

O

Feedback

This

control

adjusts

the

proportion

of

delayed

sound

from

the

E1005

output

that

is

mixed

back

into

the

E1005

delay

circuitry.

Increasing

the

amount

of

feedback

lengthens

the

duration

of

an

echo,

and

adds sustain

to

other

effects

as

well.

If

Feedback

is

set

high

enough,

oscil-

lation

(howl

or run

-away

echo)

can

occur.

This

undesir-

able

condition

can be

remedied

by lowering

the Feedback

setting.

O

Output

(Includes

Mixing Control,

Output

Jack

and

Delay

Only

Output)

The

E1005

has

two

output

jacks,

"Output"

and

"Delay

Only".

Both

are

unbalanced

phone

jacks

with

nominal

—20dB

level,

and

are designed

for

connection

to

high

impedance

circuits

such

as

instrument

amps,

mixer

inputs,

power

amplifiers, etc.

The

Mixing

control

adjusts

the

Output

jack

for

any

desired

ratio

of

direct

and

delayed

sound.

Full

counterclockwise

rotation

of

the

Mixing

control

yields

all

direct

sound;

as

the

control

is

rotated

clockwise,

more delayed

sound

is

added

until

the

Output

jack

carries

all

delayed

sound.

The

adjacent

Delay

Only

Output

jack

is

not

affected

by

the

Mixing

control;

it

always

carries

100%

delayed sound.
