Peavey

Electronics

is

proud

to

announce

the

introduction

of

a

new

line

of

exciting

Professional

Power

Amplifi¬

ers.

The

new

VX

™

series

is

the

result

of

years

of

research

&

development

into

a

smaller,

lighter,

compact

and

more

powerful

amplifier.

These

units

operate

much

more

efficiently

than

contemporary

power

amp

designs

thereby

requiring

less

current

from

the

mains

power

plug

and

consequently

produce

far

less

heating.

This

new

technology

allows

the

VX-1.5K

to

reliably

produce

more

than

1500

W

RMS

into

4

ohms

(Bridge

Mode)

in

a

two

rack

space

unit,

at

extremely

low

distortion

levels.

These

new

designs

use

a

new

class

of

operation

called

CLASS

BG.

This

class

uses

two

levels

of

power

supply

“rails,’'

but

switches

between

the

rails

faster

and

at

lower

distortion

levels

than

does

a

typical

Class

G

design.

This

unit

then

combines

higher

efficiency

and

lower

distortion,

and

together

with

our

all

new

Non-saturating

Series

Single

Emitter

Resistor

SENSITIVITY

(1)

The

maximum

input

gain

(minimum

sensitivity

rating)

is

achieved

at

the

full

clockwise

setting,

and

this

setting

yields

the

maximum

mixer/system

headroom.

A

setting

of

less

than

full

clockwise

will

yield

lower

system

noise

at

the

expense

of

mixer/system

headroom.

Calibration

indicates

sensitivity

in

necessary

to

attain

the

full

POWER

LED

(2)

Illuminates

when

AC

power

is

being

supplied

to

the

amp,

and

the

associated

channel

is

operational.

If

either

channel

were

to

experience

fault

conditions

or

to

exceed

the

safe

operating

temperature

limits,

then

that

channel

will

shut

down,

and

the

associated

power

LED

will

cease

to

illuminate,

indicating

such

conditions

exist.

Also,

whenever

the

BRIDGE

mode

is

selected,

the

power

LED

of

channel

B

is

defeated

(OFF),

just

as

if

there

were

a

fault

condition

on

channel

B.

This

provides

a

positive

indication

that

the

VX-1.5K

is

configured

for

bridge

mode.

(3)

Illuminates

when

DDT

Compression

is

taking

place

in

that

With

the

ENABLE/DEFEAT

switch

in

the

DEFEAT

position,

this

LED

indicates

when

clipping

is

occurring

in

that

channel.

CIRCUIT

BREAKERS

(4)

The

VX-1.5K

uses

circuit

breakers

in

place

of

main

fuses.

These

breakers

arc

provided

to

limit

the

current

to

the

associated

power

transformer

for

each

channel,

and

thereby

offer

protection

from

overheating

and

possible

destruction

due

to

fault

conditions

in

the

amplifier.

The.

breaker

trip

current

value

has

been

carefully

chosen

to

allow

continuous

power

output

performance,

yet

still

provide

adequate

protection

for

the

power

transformer.

Normally

these

breakers

should

not

trip

unless

there

is

a

fault

in

the

amp

circuitry

that

draws

excessive

mains

current.

However,

abnormal

conditions

such

as

a

short

circuit

on

either

or

both

channels

or

continuous

operation

at

overload

or

clipping,

especially

into

2

ohm

load

will

cause

the

breaker

to

trip.

If

this

occurs

simply

reset

the

breaker

and

correct

the

cause

of

the

overload.

When

tripped,

the

button

on

the

breaker

will

be

outward

nearly

1/2",

and

can

be

reset

by

pushing

inward.

A

normal

reset

button

length

is

about

1/4".

If

this

‘‘thermal"

type

breaker

does

trip,

then

simply

pushing

the

button

back

in

will

reset

it

after

waiting

a

brief

period

of

time

to

allow

it

to

cool

down.

If

the

breaker

trips

instantly

each

time

you

attempt

to

reset

it.

then

the

unit

should

be

taken

to

a

qualified

service

center

for

repair.

BACK

PANEL

HIGH

Z

INPUT

JACKS

(6)

Two

parallel

(bridged)

input

jacks

are

provided

for

each

channel.

This

allows

for

one

to

be

used

as

a

conven¬

tional

input,

and

at

the

same

time

the

other

to

be

used

as

a

“line

out”

(Y-cord)

to

connect

to

another

input

jack

on

this

amplifier

or

other

amps/equipment.

These

1/4"

jacks

are

not

“chassis

grounded”

and

when

used

will

provide

a

QUASI-BALANCED

input

capability

due

to

a

unique

“ground

loop”

elimination

circuitry

associated

with

the

inputs.

This

feature

will

normally

allow

"hum

free”

operation

when

relatively

short

1/4"

cable

patches

are

made

between

the

various

jacks

on

this

amp

and

other

jacks

on

various

other

equipment

that

share

the

same

rack

with

this

amplifier.

This

QUASI-BALANCED

capability

is

automatic

and

it

can

not

be

removed

from

the

system’s

circuitry.

LOW

Z

INPUT

(7)

A

conventional

three-pin,

female

XLR

input

jack

is

provided

and

may

be

used

as

the

channel

input.

When

the

(PL-2)

line

balancing

transformer

is

not

used

this

XLR

input

becomes

QUASI-BALANCED

with

pin

#3

as

the

positive

input

(connecting

to

the

tip

of

the

1/4"

input

jacks

above),

pin

#2

as

the

negative

input

(connecting

to

the

floating

sleeve

of

the

1/4"

input

jacks

above),

and

pin

#1

going

to

the

internal

power

amplifier

ground.

When

the

(PL-2)

line

balancing

transformer

is

used,

this

XLR

input

becomes

fully

TRANSFORMER-BALANCED

(Pin

#3

positive,

pin

#2

negative,

pin

#1

ground).

(See

the

PL-2

SELECTOR

SWITCH

section

for

details

on

related

settings.)

PL-2

SELECTOR

SWITCH

(8)

This

switch

is

used

in

conjunction

with

the

PL-2

transformer

to

allow

the

LOW

Z

INPUT

to

function

with

or

without

a

PL-2

module

being

inserted

in

the

receptacle.

The

“OUT”

position

of

this

switch

selects

the

QUASI-BALANCED

mode

of

operation

for

the

LOW

Z

INPUT

(XLR

jack),

and

routes

the

input

signal

directly

to

the

HI

Z

INPUT

JACKS.

In

this

position

the

HI

Z

INPUT

JACKS

may

be

used

as

outputs

after

the

LOW

Z

INPUT

to

allow

patching

this

signal

to

another

input

on

this

amp.

Normally,

in

this

switch

position,

a

(PL-2)

transformer

is

not

present

(“OUT”)

in

the

transformer

receptacle;

however,

if

one

were

“IN”

the

receptacle,

the

LOW

Z

INPUT

would

still

be

QUASI-BALANCED.

It

becomes

fully

TRANSFORMER

BALANCED

only

when

the

IN

switch

position

is

selected.

Notice

this

is

a

very

effective

means

to

“test”

for

the

necessity

of

a

line-balancing

transformer.

The

“IN”

position

of

the

switch

routes

the

signals

from

the

XLR

jack

through

the

(PL-2)

line-balancing

transformer,

thereby

selecting

the

TRANSFORMER

BALANCED

mode

of

operation

for

the

LOW

Z

INPUT.

In

this

position

the

HI

Z

INPUT

JACKS

may

be

used

as

outputs

after

the

line

balancing

transformer

to

patch

the

signal

to

another

input

jack

on

this

amplifier

or

other

amps/equipment.

If

die

“IN”

position

is

selected

without

a

(PL-2)

line-balancing

transformer

“IN"

the

receptacle,

the

LOW

Z

INPUT

will

be

rendered

inoperable.

TRANSFORMER

RECEPTACLE

(9)

This

receptacle

only

receives

the

optional

(PL-2)

line-balancing

transformer.

When

conditions

exist

that

demand

the

usage

of

a

TRANSFORMER-BALANCED

XLR

INPUT

for

ei

I

her

or

both

channels,

then

the

(PL-2)

trans¬

former

must

be

put

here,

and

the

selector

switch

must

be

in

the

“IN"

position.

DDT

SWITCH

(10)

This

switch

is

used

to

either

ENABLE

or

DEFEAT

the

DDT

compressor.

DDT

function

will

be

covered

in

more

detail

later

in

this

manual.

MODE

SWITCH

(11)

This

switch

is

used

to

select

either

STEREO

or

BRIDGE

mode

operation.

When

BRIDGE

mode

is

selected,

the

channel

B

LED

power

indicator

will

go

out

indicating

bridge

mode

has

been

selected.

Accidental

selection

of

this

mode

could

damage

loudspeakers.

The

BRIDGE

mode

will

be

covered

in

more

detail

later

in

this

manual.

SPEAKER

OUTPUTS

(12)

Two

1/4"

jacks

and

5

way

binding

post

speaker

output

terminals

are

provided.

All

these

outputs

are

in

parallel,

hence

the

speaker

connection

cables

can

be

terminated

with

1/4"

phone

plugs,

banana

plugs,

or

stripped

wires

for

use

in

the

binding

post

terminals.

For

sustained

high

power

applications,

the

use

of

the

binding

post

terminals

are

recommended;

however,

care

must

be

exercised

to

assure

correct

speaker

phasing.

Regardless

of

what

connec¬

tions

are

used,

the

typical

parallel

speaker

load

should

always

be

limited

to

2

ohms

per

channel

or

4

ohms

BRIDGE

mode

for

any

application.

Operation

at

loads

of

4

ohms

per

channel

or

8

ohms

BRIDGE

mode

is

more

desirable

for

sustained

operation

applications

due

to

the

fact

that

the

amplifier

will

run

much

cooler

at

this

load.

Operation

above

4

ohms

per

channel

and

even

open

circuit

conditions

can

always

be

considered

safe;

however,

any

sustained

operation

at

loads

below

2

ohms

could

result

in

temporary

channel

shut

down

due

to

the

thermal

limits

and/or

the

amp

fault

circuits.

MAINS

POWER

SOURCE

(120V

products

only)

(13)

The

VX-1.5K

is

filled

with

a

single

heavy

duty

#14

AWG

three

conductor

line

cord

and

a

conventional

AC

plug

with

a

large

ground

pin.

It

should

be

connected

to

an

independent

mains

circuit

capable

of

supporting

at

least

15

AMPS

continuously

or

greater.

This

is

particularly

critical

for

sustained

high

power

operation.

If

the

socket

used

does

not

have

a

ground

pin,

a

suitable

ground

lift

adaptor

should

be

used

and

the

third

wire

grounded

properly.

Never

break

off

the

ground

pin

on

the

VX-1.5K

power

amplifier.

The

use

of

extension

cords

should

be

avoided,

but

if

necessary,

always

use

a

three-wire

type

with

at

least

a

#14

AWG

wire

size.

The

use

of

lighter

wire

will

severely

limit

the

power

capability

of

this

amplifier.

Always

use

a

qualified

electrician

to

install

any

necessary

electrical

equipment.

To

prevent

the

risk

of

shock

or

fire

hazard,

always

be

sure

that

the

amp

is

properly

grounded.

GROUND

LIFT

SWITCH

(14)

This

switch

is

used

to

disconnect

the

VX-1.5K's

“signal

ground”

(both

input

and

output)

from

the

“chassis

ground."

Chassis

ground

is

the

chassis

itself,

which

is

electrically

grounded

through

the

rack

mounting

screws

to

the

external

rack

system

and

through

the

mains

line

cord

via

the

large

ground

pin

to

the

mains

ground.

It

is

often

advantageous

to

“lift"

the

signal

ground

from

chassis

ground

to

eliminate

a

“ground

loop"

which

has

caused

unwanted

ground

current

in

the

signal

cables

between

the

external

preamp

and

this

power

amplifier.

Such

conditions

can

create

excessive

hum

levels

in

the

power

amplifier

output

and

render

the

system

useless

in

low

level

applications.

In

this

case

"lifting"

the

ground

should

solve

this

hum

problem.

Ground

lift

is

selected

when

the

switch

is

in

the

right

or

“LIFT"

position.

If

lifting

the

ground

does

not

eliminate

a

particular

hum

problem,

then

we

recommend

you

defeat

the

ground

lift

feature.

Please

note

that

using

this

ground

lift

feature

still

leaves

the

chassis

itself

grounded

electrically

through

the

mains

line

cord.

Having

the

chassis

grounded

avoids

any

possibility

of

an

electrical

shock

or

a

fire

hazard.

This

ground

lift

feature

should

never

be

confused

with

the

practice

of

"floating"

the

large

ground

pin

at

the

AC

mains

receptacle

to

eliminate

a

ground

loop.

Floating

the

ground

pin

on

any

electrical

equipment

is

just

asking

for

trouble!!!

hv

automatic

two-speed

internal

fans.

All

the

input

and

output

connections

are

on

the

back,

panel.

The

front

panel

contains

LED

indicators

for

power

and

DDT

activation,

detented/calibrated

sensitivity

controls,

and

a

mains

power

switch.

INDUSTRIAL

AND

COMMERCIAL

INSTALLATIONS

For

commercial

and

other

installations,

where

sustained

high

power

operation

is

required,

the

VX-1.5K

should

be

mounted

in

a

standard

19"

rack.

It

is

not

necessary

to

leave

rack

space

between

each

amplifier

in

the

stack,

since

the

fan

pulls

air

in

from

the

rear

and

exhausts

the

hot

air

out

the

front.

An

adequate

‘'COOL"

air

supply

must

be

provided

for

the

amplifier

when

rack-mounted.

The

internal

fan

must

have

a

source

of

air

that

is

not

preheated

by

other

equipment.

The

amplifier

will

start

up

in

‘LOW

SPEED"

fan

operation,

and

will

normally

stay

at

low

speed

operation

unless

sustained

high

power

operating

levels

were

to

occur.

Then

as

the

amplifier's

"HEAT

SINKS"

heat

up.

the

automatic

thermal

sensing

circuitry

will

cause

high

speed

operation

to

occur.

Depending

upon

signal

conditions

and

amp

loading,

high

speed

fan

operation

may

continue,

or

it

may

cycle

continuously

between

high

and

low.

This

situation

is

quite

normal.

If

cooling

is

inadequate

due

to

preheated

air,

or

a

reduction

of

air

flow

occurs

due

to

blockage

of

the

amplifier

inlel/outlet

ports,

or

if

the

amplifier

is

severely

overloaded

or

short

circuited,

then

the

amplifier

thermal

sensing

system

may

cause

temporary

shutdown

of

that

particular

channel.

This

is

indicated

by

the

channel

power

LED

on

the

front

panel

ceasing

to

illuminate.

Depending

upon

available

cooling

air,

operation

should

be

restored

in

that

channel

relatively

quickly,

and

the

power

LED

will

be

illuminated.

In

any

event

corrective

action

should

be

taken

to

determine

the

cause

of

the

thermal

shutdown.

If

the

amplifier

is

not

severely

overloaded

or

shotted,

and

air

flow

is

normal

in

and

out

of

the

unit,

then

steps

should

be

taken

to

provide

a

cooler

environment

for

all

the

amplifiers.

As

a

general

rule,

the

cooler

electronic

equipment

is

operated,

the

longer

its

useful

service

life.

STUDIO

AND

HOME

INSTALLATION

In

most

low

to

medium

power

applications,

the

VX-1.5K

can

be

mounted

in

any

configuration.

It

is

desirable

that,

if

at

all

possible,

the

unit

be

located

at

the

lop

of

an

equipment

stack.

This

will

prevent

possible

overheating

of

any

sensitive

equipment

by

the

hot

air

rising

from

the

power

amplifier.

As

a

general

rule,

most

home

and

studio

requirements

will

never

cause

high

speed

fan

operation.

If

it

does,

however,

this

may

indicate

that

you

have

not

taken

the

necessary

steps

to

provide

adequate

cooling.

Remember,

dosed

up

in

a

cabinet,

the

VX-1.5K

will

have

severe

cooling

problems,

even

at

low

power

levels.

Again,

inadvertent

short

circuit

or

sustained

over¬

loaded

usage

could

also

cause

temporary

thermal

shutdown.

Also,

most

home

wiring

and

electrical

circuits

are

only

15

AMPS.

Two

VX-1.5K*s

could

cause

a

power

panel

15

AMP

circuit

breaker

to

trip

if

a

severe

overload

occurs.

BRIDGE

MODE

The

bridge

mode

on

stereo

amplifiers

is

often

misunderstood

as

to

the

actual

operation

and

usage.

In

basic

terms,

when

a

two

channel

amplifier

is

operated

in

the

BRIDGE

mode,

it

is

converted

into

a

single

channel

unit

with

a

POWER

RATING

equal

to

the

sum

of

both

channel’s

power

ratings,

and

at

a

LOAD

RATING

of

twice

that

of

the

single

channel

rating.

In

this

case

the

VX-

1.5K

is

rated

at

750

W

RMS

per

channel

into

2

ohms.

Thus

the

BRIDGE

RATING

is

1500

W

RMS

into

4

ohms

(minimum

load).

Bridge

mode

operation

is

accomplished

by

placing

the

mode

switch

in

the

“BRIDGE"

position,

connecting

the

load

between

the

RED

binding

posts

of

each

channel,

and

using

channel

A

as

the

input

channel.

All

the

channel

B

functions

as

an

input

are

defeated

and

they

serve

no

purpose

in

bridge

mode.

A

popular

application

for

BRIDGE

mode

operation

is

to

drive

sound

distribution

systems

in

large

public

address

applications.

In

this

mode,

the

VX-

1.5K

power

amplifier

can

actually

drive

70

volt

systems

directly

without

using

expensive

matching

transformers.

The

real

advantage

of

such

an

approach

is

primarily

cost.

70

volt

distribution

systems

are

very

common

in

applications

where

rather

large

numbers

of

relatively

small

loudspeakers

are

used

for

BACKGROUND

MUSIC

AND

PAGING.

Such

systems

require

the

use

of

70

volt

TRANSFORMERS

at

each

loudspeaker.

Another

common

use

for

the

BRIDGE

mode

is

in

SUBWOOFER

applications

where

very

high

power

levels

are

required

to

adequately

reproduce

the

extreme

low

frequencies.

Such

enclosures

usually

contain

2

or

4

loudspeakers

to

handle

the

power

levels

involved.

For

bridge

mode

usage,

the

enclosure

impedance

must

be

4

or

8

ohms;

never

below

4

ohms!

Also

make

sure

that

the

enclosure

can

handle

1500

watts

reliably.

DDT

COMPRESSION

Peaveyks

patented

DDT

compression

system

enables

the

sound

man

to

maximize

the

performance

of

die

ampli¬

fier/speaker

combination

by

preventing

the

power

amp

from

running

out

of

headroom

(clipping).

This

compres¬

sion

system

is

activated

by

a

very

unique

circuit

that

senses

signal

conditions

that

might

overload

the

amplifier

and

activates

compression

(reduces

the

amp

gain)

when

clipping

is

imminent.

Threshold

of

compression

then

is

clipping

itself

and

no

specific

threshold

control

is

used.

This

technique

effectively

utilizes

every

precious

watt

available

for

the

power

amplifier

to

reproduce

the

signal

while

at

the

same

time

minimizes

clipping

and

distor¬

tion,

and

thus

significantly

reduces

the

potential

of

loudspeaker

degradation

and

damage.

The

DDT

system

is

automatic,

hands-off

approach

to

the

problem

of

power

amplifier

clipping.

Since

the

VX-1.5K

power

amplifier

uses

circuit

breakers

for

the

over-current

protection,

the

DDT

compression

system

plays

even

a

more

important

roll

in

continuous

performance

by

preventing

each

channel

from

dipping

and

overload.

Notice

continuous

operation

at

clipping

can

cause

the

circuit

breaker

to

trip,

but

with

the

DDT

activated

this

problem

is

minimized.

For

this

reason

you

should

always

have

the

DDT

compression

system

enabled.
