ALL SPECIFICATIONS SUBJECT TO CHANGE

WITHOUT NOTICE.

The Hafler PRO5000 is a high power, low profile, two

channel power amplifier intended for professional sound

installations. It is the result of modern packaging combined

with the performance and reliability characteristics found

in previous Hafler designs. The PRO5000 has an optimized

combination of features needed for a professional power

amplifier: high power, small package size, rugged case

construction, balanced inputs, full bridgeability for mono

applications, continuously variable DC fan for quiet op-

eration, and a variety of simple, yet effective protection

systems. Above all, however, the PRO5000 maintains the

well known

Hafler

tradition of superior sounding power

amplifiers.

OVERVIEW OF AMPLIFIER

The PRO5000 is a standard two-rack height fan cooled

design utilizing fully complimentary drive circuits and

lateral type MOSFET output transistors. The amplifier has

full subtractor balanced input circuits for good noise rejec-

tion. The drive circuitry is a high performance arrangement

with a double differential JFET input stage. Film capacitors

are used throughout the circuitry to ensure minimum deg-

radation of the audio signal.

The 19” extruded aluminum front panel includes handles

for ease of installation, separate gain controls for each

channel, signal present and clipping indicators for both

channels, and the power switch which has a pilot lamp. The

rear panel has both

1/4”

phone and XLR connectors for the

inputs,

5-way

binding posts for the outputs, a switch to

bridge the amp for mono mode. and a switch to connect or

disconnect the audio ground from the chassis ground.

The protection systems include separate power supply

fuses on DCV+ and

DCV-

for each channel, thermal

sensing circuits that monitor output device temperature and

correspondingly control the DC fan, a relay to disengage

the load if excessive DC offset is detected or if the output

device temperature becomes too high, a delay to avoid

dangerous turn-on/off transients, and an AC line fuse if all

else fails. This amplifier does not have, and by virtue of

design, does not need the current limiting circuits which are

required to protect conventional bipolar or vertical MOSFET

output devices. The less common lateral

MOSFETs

used in

Hafler

amplifiers inherently limit the current ONLY under

abnormal conditions, thus avoiding ‘thermal runaway’ and

subsequent device destruction. This gives the dual advan-

tage of greater reliability from simpler circuitry, and the

elimination of one of the chief causes of distorted signals

the harsh sounds of the actuation of complex protective

circuits.

Grounding and Polarization

The power supply cord is of a polarized type designed

to reduce the risk of electric shock sustained from a live

cabinet. It is assumed to be of a suitable length for most

uses of the equipment. The use of extension cords and

power strips is discouraged unless they are of suitable

rating to deliver the required current for safe equipment

operation and can be used so that the polarization of

the plug is not defeated. If an extension cord is required,

it is important that the blades of the plug be able to insert

fully into the receptacle. Professional amplifiers with a

S-conductor line cord must never have the ground pin

of the plug defeated.

Non-Use Periods

During extended periods of non-use the power supply

cord should be kept unplugged from the power source.

Cleaning

The equipment should be cleaned only as detailed by

the owners manual.

Object

and Liquid Entry

Care should be taken so that

objects

and/or liquids,

such as cleaning fluids, are not spilled into the enclosure

of the equipment.

Damage Requiring Service

HafIer

equipment should be serviced by qualified ser-

vice personnel when:

The power supply cord or plug has been

damaged; or

Objects

have fallen, or liquid has been spilled

into the equipment; or

The equipment has been exposed to rain; or

The equipment does not appear to operate

normally or exhibits a marked change in per-

formance; or

The equipment has been dropped, or the en-

closure damaged.

lines.

18.

Outdoor Antenna Grounding

If an outside antenna is to be used with the

HafIer

Tuner,

be sure that the antenna system is grounded so as to

provide some protection against voltage surges and built

up static charges. Section 8

of the National

Electrical

Code,

ANSl/NFPA

No.

INSTALLATION

MOUNTING

The front panel is designed to fit a standard

19”

rack at

2” intervals or alternatively the unit may be stacked. NOTE:

When rack mounting the

PRO5000,

the rear of the amplifier

must be fastened to the rack via the rear mounting holes to

eliminate large torque forces on the faceplate. The feet may

be removed if desired when rack mounting.

VENTILATION

Do not block the air flow into or out of the amplifier. Air is

drawn in through the vents in the front panel, and is

exhausted out the side vents. Therefore, when rack mounting

in a cabinet, allow sufficient space between the inside walls

of the rack and the amplifier chassis, (at least 2 inches). If

the cabinet has

front door, the door must have large enough

vents to allow enough volume air flow for each amplifier in

the rack, (80 CFM per PRO5000 should be adequate). A

good alternative is to augment the air flow with a rack

mounted fan that pressurizes the space in front of the

amplifiers and/or evacuates the air space in the rear of the

cabinet.

The PRO5000 includes a removable dust filter assembly

attached to the outside of the front intake vents. This filter

should be removed occasionally and cleaned. To remove,

gently squeeze the ends inward and pull the filter frame

straight out from the front panel. The foam filter element

may then be removed from the frame and shaken or blown

out with compressed air. If the foam is particularly dirty, it

may be washed with mild soap and warm water. Replace-

ment foam elements are available from the factory, part

number HWH-392.

CONNECTIONS

AC LINE CORD:

High power output puts heavy demands on the AC supply

to the amplifier. A single PRO5000 delivering 4 ohm rated

power will heavily load a typical 15 amp circuit. Multiple

amplifiers will need to be connected to a circuit capable of

delivering the required current (see specifications), in order

for the amplifiers to produce the expected audio power.

The PRO5000 is normally wired for

12OV

6OHz

operation,

as in the USA. The transformer can be rewired to accom-

modate other line voltages upon request. Note that the value

of the internal AC line fuse (near the power switch), should

be changed when converting from lower line voltages

(

12OV

or less use a 15 amp Slo-Blo), to higher line voltages

(200V and up use a

7-1/2

amp Slo-Blo). Never wire the

amplifier for a lower line voltage than what is supplied in an

attempt to obtain greater output power. Such an attempt will

very likely damage parts in the amplifier not rated for the

higher voltages that will result, and the warranty will be

voided.

3-wire

grounded power cord is supplied. It must be

connected to a properly grounded (earthed) AC receptacle

for safety. Do not break off the ground pin on the plug to

avoid using the proper adapter for

2-wire

receptacles.

SIGNAL INPUT:

Both

1/4”

phone and XLR balanced connectors are pro-

vided on the back panel. These connectors are wired in

parallel for each channel, so that either may be used with no

further switching. The unused connector may be used to

“daisy chain” other amplifiers from the same source using

the appropriate cables.

To achieve maximum noise rejection, balanced lines should

be used for the inputs (two out-of-phase polarity signal

conductors plus a ground shield). The XLR connectors are

wired for the IEC international standard, which connects

the #1 pin to the ground shield; the

pin as the

non-

inverting or ‘hot’ signal; and the

pin as the inverting or

‘return’ signal. The phone jacks are wired with the sleeve

as the ground shield; the tip as the non-inverting signal; and

the ring as the inverting signal. Note that in other equip-

ment the two signal connectors are sometimes interchanged

from what is stated here-it is therefore wise to check for

consistency among the equipment being installed.

For an unbalanced input line (one signal conductor and a

ground shield), connect the signal conductor to the

non-

inverting input, and connect the ground shield to the input

ground AND the inverting input of the amplifier. Note that

with a two conductor

1/4”

phone jack, this connection is

automatically made, assuming that the sleeve (which is

longer than that of a three circuit phone jack and includes

the ring) is the ground shield and the tip is the signal. In this

case, simply insert the phone jack fully into the input of the

amplifier.

For bridged mono operation, only use the channel A input

and set the mono/stereo switch to mono. Make no connec-

tion to the channel B input jacks. In this mode the channel

A gain control determines the gain of the amplifier. See

below for a description of loudspeaker connection in this

mode.

To prevent noise or hum, it is essential that all input

connections are secure, and that the cables are not frayed or

loosely connected to the plug.

OUTPUT:

The red and black binding posts will accept a variety of

speaker lead terminations, the most convenient of which

-4-

HWH-392

are the ‘banana’ plug connectors with

3/4”

spacing. Bare

wire can be inserted through the vertical holes in the shafts,

which are visible when the caps are unscrewed. To be

certain that no strands of wire are unsecured, it is best to tin

the wire end before insertion. Alternatively, a spade lug

soldered

to the wire end will make a good connection.

Make all connections between loudspeakers and the ampli-

fier with the power shut off to avoid loudspeaker damage.

Select wire of sufficient size to preserve the high damping

factor of the

PRO5000.

The minimum recommended wire

size is #1

gauge when high power output is expected.

Larger wire sizes are necessary for long runs, or if the

speaker impedance is less than

ohm.

PHASING:

Consistent phase relationships are important when con-

necting speakers in order to enable full bass reproduction as

well as midrange and high frequency time alignment. To be

sure all speakers in a system are wired in phase to the

amplifier, each

ground or

speaker terminal should be

connected to its black ground terminal on the

PRO5000,

and the speakers

terminal to the corresponding red

terminal. Speaker connecting cable identifies one wire

from the other by color of the wire, or by marking or

coloring the insulation. NOTE: In the special case of

monophonic operation of the

PRO5000,

(described below)

different speaker connections are employed.

GROUNDING

The black output terminals of the PROS000 are connected

together internally and grounded to the chassis. This fa-

cilitates the use of external devices which use a common

ground connection, such as some headphone junction boxes.

You must be sure that the ground or shield connection from

such a device goes to a black terminal on the

PRO5000.

NOTE: No such connection may be made when the

PROS000 is connected for bridged mono operation.

The back panel of the PRO5000 also contains a chassis/

float groundswitch forground isolation. This switch should

be set for minimum system hum and/or noise.

BRIDGED MONO OPERATION:

To drive a single loudspeaker with increased power capa-

bility, the PRO5000 can be operated in the bridged mode

which drives both channels with the same signal and

combines their output to deliver more than 900 watts to an

ohm speaker.

this arrangement, the speaker is con-

nected only to the two red output terminals. The channel A

terminal is the

"+",

and the channel B terminal is the

"-"

connection. No connections should be made to either black

output terminal in this configuration.

OPERATION

APPLYING POWER:

Standard practice is to turn power amplifiers on last and off

first in the chain of electronics. This minimizes the likeli-

hood of damage to the load from turn-on and turn-off

transients generated by source equipment. The PROS000

provides built-in protection from such transients by incor-

porating a delay of approximately 3 seconds before the

relay connects the loudspeakers. If a longer delay is re-

quired, contact the

Hafler

Technical Service Department.

The pilot lamp in the power switch will glow whenever

power is applied to the

PRO5OOO.

If it does not light, check

for a blown internal AC line fuse. Otherwise, check the line

circuit breaker for a fault.

FRONT PANEL INDICATORS:

The presence of any signal above the noise

floor

will

activate the green ‘Signal’ lights for each channel. The red

‘Clip’ indicators are activated by a comparator circuit which

triggers when the output distortion level reaches approxi-

mately 3%. They indicate when the demands of the ampli-

fier exceed its output capability. Because the dynamics of

good source material may include steep waveforms which

reach these limits for a small fraction of a second, normal

actuation would cause them to flicker so briefly that the eye

would miss it. In the interest of giving maximum informa-

tion, a “hold” circuit is included which extends these brief

pulses to about

1/4

of a second, so they will be clearly

visible. However, these occasional flashes do not indicate

that the amplifier is being substantially overdriven. Thus,

these lamps may operate quite differently from similarly

marked indicators on other amplifiers.

GAIN CONTROLS:

The gain controls for each channel are precision potenti-

ometers, designed for very low distortion. Unless there is a

specific purpose for an intermediate setting (such as level

matching), the gain controls are usually fully advanced

clockwise. This is the setting for which the amplifier’s

sensitivity and voltage gain are specified. Note that in the

bridged mono mode, the channel A control determines the

gain of the amplifier.

DC OFFSET:

If at any time the DC voltage rises to an unsafe level at the

outputs. the relay will disconnect the loudspeakers from the

amplifier. It should be noted that very high levels of low

frequency energy can sometimes imitate DC at the output,

and might activate the relay protection inappropriately. If

this becomes a problem, the level of DC protection provided

can be changed by consulting the

factory.

PARTS LIST PRO 5000

THERMAL PROTECTION:

The PRO5000 is equipped with a unique protection system

that continually monitors the temperature of the output

devices and takes corrective action to prevent damage to

the amplifier as a result of overheating. Under most con-

ditions, the

PRO5OOO’s

cooling system can dissipate the

heat required to maintain safe operating temperatures, and

the unit will play continuously. If the amplifier is driven at

high volumes into speakers with an impedance of less than

4 ohms, and/or there is inadequate ventilation, the

heatsink

could heat to a level that would cause the protection

circuitry to shut the unit off for a short time (normally less

than 1 minute), to prevent damage. The PRO5000 will

return to normal operation, and if the overheating condition

is still present the cycle will repeat. In this case, check the

surroundings of the amplifier to ensure sufficient air flow

into and out of the vents. Otherwise, check the load im-

pedance connected to the outputs to see if it is far below 4

ohms.

FUSES:

The PRO5000 is supplied with an internal 15 ampere

Slo-

Blo

AC line fuse. For continued protection, replace this

fuse only with the same type and rating. The fuse is located

on the inside wall near the power switch.

The four power supply fuses on the printed circuit board are

there to protect the output devices if excessive current is

drawn (e.g. a short circuit across the output terminals).

Replace only with 10 ampere 3AG type fuses.
