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 op­eration, 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 rejec­tion. 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 deg­radation 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 advan­tage 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.

The equipment should be kept away from areas of high
temperature, such as heater vents, radiators, stoves/
ovens, fireplaces, etc.

6.

Ventilation

The equipment should be used in an area suitable for
proper ventilation. Care should be taken to not impede
airflow in and around the cabinet. Do not mount on a
carpeted shelf or in an enclosure consisting of more than
five sides. Allow for proper clearance above the equip­ment.

Power Cord Protection

NOTICE - IMPORTANT SAFETY INFORMATION

DO NOT DISPOSE OF - KEEP FOR FUTURE REFERENCE

Safety Instructions

Power cords should be run so that they do not interfere
with the movement of

objects

in the room - people, fan
blades, utility carts, etc. Also, care should be taken that
the cord is not pinched or cut, and placed so that it is not
in danger of being pinched or cut, as in under a rug,
around a tight corner, etc.

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.

INSTALLATION

MOUNTING

The front panel is designed to fit a standard

19”

rack at 3-

l/

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 a 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. Replace­ment 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 accom­modate 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.

A

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 pro­vided 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

#2

pin as the

non­inverting or ‘hot’ signal; and the #3 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 equip­ment 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

non­inverting 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 connec­tion 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-

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 ampli­fier 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

6

gauge when high power output is expected.

Larger wire sizes are necessary for long runs, or if the
speaker impedance is less than

8

ohm.

PHASING:

Consistent phase relationships are important when con­necting 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 fa­cilitates 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 capa­bility, 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
8

ohm speaker. In this arrangement, the speaker is con­nected 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 likeli­hood 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 incor­porating a delay of approximately 3 seconds before the
relay connects the loudspeakers. If a longer delay is re­quired, 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 approxi­mately 3%. They indicate when the demands of the ampli­fier 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 informa­tion, 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.

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 con­ditions, 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 im­pedance 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.
