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.

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

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.
