INTRODUCTION

The Hafler P1000 is a single rack height, two channel professional power amplifier suitable for use in any situation
where a moderately powered compact amplifier is required. The P1000 is particularly attractive for use in broadcast
monitoring situations. Our trans•ana circuit topology and MOSFET output stage ensures trouble-free, long term
operation and is backed by our five year warranty.

This manual contains information on using the P1000 amplifiers. It is organized into three main sections.
“Installation” covers the location and connection of the amplifier in the system. Like many precision
components, careful attention to the initial setup can yield dividends in higher performance and trouble-free use.

“Operation” covers the controls and features of the amplifiers and how to use them to get the best effect. The
“Technical Reference” section contains field service information; in addition to the schematic and parts list there

are block diagrams and circuit operation explanations useful for technicians. We strongly urge reading over the
Installation and Operation portions of this manual before putting the amplifier into service.

The circuitry used in the Hafler Professional power amplifiers is our trans•ana (TRANSconductance Active Nodal
Amplifier) topology. The trans•ana technology operates the output stage with its full voltage gain, which allows
the input stage to operate from a low voltage regulated supply. The signal is then shifted up in level to the high
voltage section by the driver stage which forms an active node at ultrasonic frequencies. This results in very stable,
highly linear operation.

Safe Area output protection is handled by our proprietary NOMAD (NOn-Multiplying Advanced Decision, patent
pending) system. NOMAD accurately computes the allowable device current for the device voltage and clamps the
gate drive when the actual current exceeds this value. This improved accuracy is achieved by eliminating the
dependence upon unreliable analog IE multiplier circuits to model the device operation.

Other specialized circuits which prevent damage to the amplifier and speakers have been carefully implemented.
A soft start circuit prevents sending potentially destructive turn-on and turn-off transients to the speakers. A
thermal sensing network continuously monitors the heatsink temperature and shuts down the amplifier to protect
it from excessive operating heat.

Each channel of the amplifier has been built as a self-contained module. This modular arrangement simplifies
construction and improves service accessibility. The circuit board assembly makes extensive use of surface mount
components in the low power portion of the audio circuitry. Automated equipment is used to place and solder the
components which yields greater uniformity and reliability.

The front panel has controls for input level adjustment and the power switch. In addition, LED indicators give a
visual representation of the operating status of each channel. The THERMAL indicator lights to show when this
protection circuit has been activated. The CLIP indicator helps prevent damaging the speaker by showing when
the amplifier is overdriven. The SIGNAL indicator lights to show the presence of an audio signal.

I NSTALLATION

LOCATION

The P1000 power transformer can generate a substantial magnetic field, so caution should be exercised in the
placement of low level components such as a tape deck, mixer or mic preamp to avoid inducing noise in the low
level circuitry. The amplifiers can also produce considerable heat in normal operation so the primary consideration
when determining a location for the amplifiers is to allow for adequate ventilation. The large heatsinks provide
unrestricted airflow, but care must be taken to keep the slots in the bottom panel and top cover clear. If the amplifier
is mounted in an equipment rack, make sure adjacent equipment does not impede cool air flow.

Rack systems should have two fans 4" to 5" in from the front of the amplifier blowing upward.

!

Inadequate ventilation can shorten component life, especially when other equipment raises the ambient air
temperature, so circulating fans should be considered in tight quarters.

• Fans placed 4" to 5" from front of unit

• Fans placed under the unit pointing upwards

• Recommended P1000 fan is 32 CFM x 2

AC LINE

The P1000 is capable of operation from either a 115 VAC/60Hz or a 230 VAC/50-60Hz power line. The power line
selector switch is located on the rear panel. Check that the switch is set in the correct position before putting the
amplifier into service.

Connection is made by a 16 gauge, IEC Type 320, grounded line cord. For safety considerations only a properly
grounded (earthed) receptacle should be used. If a grounded circuit is not available, do not break off the ground
pin; use the proper adapter plug for a two wire receptacle.

IMPORTANT: The power line fuse is mounted on the rear panel of the amplifier. If this fuse blows, replace

it only with a fuse of the same type and rating. The correct replacement fuse value is printed in the

!

parts list.

UNBALANCED INPUT

The unbalanced inputs use conventional RCA phone jacks. Set the BALANCED/UNBALANCED switch to the
UNBALANCED position to use these jacks.

BALANCED INPUT

The balanced input jacks are dual function connectors which accept 1/4" Phone (Tip Ring Sleeve) or XLR plugs.
The 1/4" Phone jack is connected according to conventional usage. The XLR jack is connected according to the
IEC and AES standard. Set the BALANCED/UNBALANCED switch to the BALANCED position to use these jacks.

HEADPHONE JACK

A standard 1/4" headphone jack is mounted on the front panel of the amplifier. The headphones are connected to
the output of the amplifier and can be adjusted by the input level controls or the main volume control.

CAUTION: Using headphones at high power levels can cause permanent hearing damage. Always turn

!

the volume all the way down before putting the headphones on.

OUTPUT CONNECTIONS

The speaker output connectors are screw terminals on a barrier strip. The terminals are sized for 1/4" spade lugs.

MONOPHONIC USE

In systems with high power requirements, the amplifiers can be configured for single channel, bridged mono
operation. To bridge the amplifier, set the front panel Normal/Bridged Mono switch to the MONO position. The
Channel 1 input and level control is used and the Channel 2 level control is not active. The speaker is connected
to the two positive (+) terminals.

When the amplifier is bridged the output is floating. Any speaker which requires a common ground from

!

the amplifier output cannot be used in this application. Never connect a positive (+) terminal to ground.

Since a bridged amplifier shares the load between the two channels, each channel will effectively drive half

!

of the load. Therefore, for bridged mono operation we recommend using an eight ohm load as the minimum
impedance.

OPERATION

POWER SWITCH

The POWER switch is located on the front panel of the amplifier. An internal lamp indicates when it is turned on.

Standard practice is to turn the amplifier on last and off first when switching components

!

individually to prevent sending damaging transients, generated in the source components, to the
speakers.

It is possible to leave the power switch in the on position and switch the amplifier remotely through a power
distribution block or preamp switched outlet. When doing so make sure the switch is rated for the current required
by the amplifier.

LEVEL CONTROLS

The input sensitivity, for each channel, can be adjusted individually using the level controls on the front panel.
The level controls on the P1000 are configured to allow each channel to be fully attenuated and are marked from
0 (minimum output) to 10 (full output).

In public systems where it is necessary to match levels, the knobs can be removed and the controls adjusted with
your fingers or a flathead screwdriver. Cover the holes with the enclosed plugs to restrict access.

INPUT CONFIGURATION SWITCHES

Balanced/Unbalanced

When the Balanced/Unbalanced switch position is in the Unbalanced position, the return (–) terminal is
connected to ground to prevent unstable amplifier operation when the RCA input jacks are used. When
using the XLR or 1/4" inputs, set the switch in the Balanced position. If the amplifier output is low, or has
excessive noise, make sure this switch is set to the correct position.

Normal/Bridged Mono

The amplifier operates in two-channel mode when the front panel NORMAL/BRIDGED MONO switch is
in the NORMAL position. To use the amplifier in single channel, bridged mono applications, the front
panel switch must be in the BRIDGED MONO position. When the switch is set in the BRIDGED MONO
position, the Channel 1 (+) and (–) inputs are connected to Channel 2 in reversed polarity, which inverts
the Channel 2 output. Only the Channel 1 input is used, and the speaker is connected to the two positive
(+) output terminals. The amplifier gain is adjusted by the Channel 1 level control; the Channel 2 control
is not active.

Because of thermal considerations we do not recommend using less than a nominal eight ohm

!

load on the amplifier when running it in bridged mono.

GROUND SWITCH

Ground loops are characterized by a hum or buzz through the speakers and are caused by a voltage potential
difference between two points in a ground circuit. Ground loops are aggravated when multiple paths exist for a
given circuit. Mounting components in a rack with metal rails may introduce ground loops between associated
equipment, because the rails can establish an additional ground path.

The CHASSIS/FLOAT switch allows you to select the amplifier grounding scheme for best system compatibility.
With the switch in the CHASSIS position all signal grounds are referred to the chassis and power line ground.

In the FLOAT position the signal ground is decoupled from the chassis. The position of the switch is determined
by the overall noise in the system; choose the position which gives the lowest hum.

NOMAD (NOn-Multiplying Advanced Decision, patent pending) SAFE AREA PROTECTION
The output MOSFETs have an upper limit on the power, current, or voltage they can withstand without being
damaged. The operating range within these limits is called the Safe Operating Area.

Traditional amplifier designs use sensing circuits to measure the device voltage and current and a multiplying
circuit to determine whether the dissipation (power) is within the Safe Operating Area. Limiter circuits are then
activated to prevent exceeding the device ratings. This multiplication method has numerous problems,
including temperature sensitivity, nonlinearity and complexity.

The NOMAD circuit, used in the P1000, avoids these problems by deriving the device dissipation by a different
method. Sensing circuits measure the device voltage and current. NOMAD determines the allowed current after
an established duration. A clamping transistor is activated to limit the gate voltage.

LED INDICATORS

Amplifier operation is monitored internally and each channel has three status LEDs. These indicators can be
used for system troubleshooting in case of aberrant behavior.

Signal

Monitors the amplifier output and lights when a signal is present. The SIGNAL indicator is calibrated
to activate at an equivalent input voltage of 30mV, with the amplifier set for full gain.

Clipping

Monitors the DRIVE SIGNAL and lights when the drive signal voltage exceeds the maximum level for
linear operation of the output MOSFETs.

Thermal

Indicates when the thermal protection has shut down the amplifier. This occurs when the heatsink
temperature becomes excessive.

WARM UP

In order to achieve the best sonic performance and image stability from the amplifier, we recommend letting
it warm up for 1 hour before beginning any critical listening.

CLEANING AND MAINTENANCE

There is no requirement for regular maintenance on the electronic components of the amplifier. If the case
becomes soiled it can be cleaned using a soft cloth and a mild detergent, such as spray window or glass cleaner.
If the amplifier is located in a particularly dusty environment, cleaning the inside with compressed air or
vacuuming every 18 to 24 months is sufficient.

TECHNICAL REFERENCE

FIELD SERVICE CONSIDERATIONS

A primary focus during the design and development of the P1000 was to ensure the dependability of the amplifiers. The
use of MOSFET output transistors and the low voltage trans•
for the circuit assembly made the reliability goals achievable. However, a parallel effort was also undertaken to make
sure any down time caused by an amplifier fault was minimized by making the amplifier technician “friendly.” The
modular construction allows exchanging the entire operational portion of either channel quickly and easily without the
need for soldering or specialized equipment.

This section of the manual contains descriptions of circuit operation and block diagrams to assist technicians with
component level repairs.

ana

input stage combined with careful component selection

THEORY AND OPERATION OF trans•

The trans•
Vertical MOSFET output transistors. The input and pre-driver stages operate at low voltage and the output MOSFETs are
connected in a source-on-rail configuration to deliver their full voltage gain.

Using the output stage to supply voltage gain inherently increases the power gain (for the same bandwidth) of the output
stage by typically ten times over the conventional follower connection, using the same MOSFET devices. This increase
in efficiency allows the use of a much simpler input section than in the more common high voltage designs. The number
of serial stages, from input to output has been reduced from five or more to only four in the P1000.

The transition from the low voltage input processing to the high voltage output operation is handled by a pair of
complementary bipolar driver transistors. The drivers form an
accurately to the gates of the MOSFETs. This results in highly stable and highly linear performance.

The trans•
of its simplicity and efficiency. The circuit configuration does not require separate high voltage power supplies thus
reducing the size and complexity of the power transformer. The vertical MOSFETs used in the P1000 have a lower “on
resistance” than the lateral MOSFETs used in our other amplifiers which results in less operating heat. This allows for
a reduction in the size of the heatsinks and makes the single rack size of the P1000 practical.

The sonic character of the P1000 is similar to our larger trans•
surpasses any other similarly sized amplifiers.

CIRCUIT OPERATION

trans•ana Implementation

The transistor Q1 is configured to operate as a switch which controls the constant current source, Q6, of the input
differential amp, Q4 and Q5. When Q1 is off the emitter voltage is low turning off Q6. Timing of the Soft Start function
is controlled by the charging time of C29 through R13. The THERMAL Protection circuit uses Q1 to shut down the
channel when excessive heat is detected.

U1A and U1B are buffer amps configured as unity gain, non-inverting voltage followers. The output of these buffers is
fed to the attenuator network controlled by R24. The buffer amp U2A stabilizes the impedance at the non-inverting
differential input Q4. U2B is configured as a DC servo-integrator to null the output offset voltage.

Transistors Q19 and Q20 are the second gain stage and are the pre-drivers of the output stage drivers Q21 and Q22.

The driver stage level-shifts the signal from the low voltage operation of the input circuit to the high voltage operation
of the output stage. Drive current for the positive output MOSFETs is supplied by the current amplifier Q23 and Q24.
Drive current for the negative output MOSFETs is supplied by the current amplifier Q25 and Q28.

Class AB bias current is established by Q18 and adjusted by RV1. Local feedback is supplied by the network C16, R82
and R102, and global feedback by C10 and R35.

CALIBRATION

WARNING: Only a competent technician should attempt the following procedure.
Adjusting Bias:

The bias control establishes the quiescent Class AB output current of the amplifier. The bias should not need
readjustment from the factory setting; however, if the amplifier is repaired and output devices have been changed, or
if the two channels of the amplifier do not run at the same temperature, recalibrating the bias is necessary. Disconnect
the power to the amplifier before removing the cover. To adjust the bias, disconnect the input and speakers and remove
the jumper J4. Connect an amp meter across the exposed pins. The correct polarity is marked adjacent to the jumper.
Adjust RV1 to get a current reading of 100mA.

WARNING: Only a competent technician should attempt the following procedure.
Calibrating Common Mode Rejection:

The input common mode null is adjusted by the trim pot R8. The CMRR should be greater than 70dB below rated output.
If the CMRR requires adjustment, feed the amplifier input with a common mode signal and adjust R8. Disconnect the
power to the amplifier before removing the cover. Use a sinewave generator set to 1 volt output at 1kHz. Connect the
generator signal output to the tip and ring of a 1/4" plug and ground to the sleeve. Plug this into the amplifier input.
Connect an AC voltmeter to the amplifier output binding posts. Adjust R8 to give the lowest voltage output from the
amplifier. For a temporary adjustment when a signal generator and voltmeter are not available, use an FM tuner and
tune it to an unused station as your signal source, and connect the signal to the amplifier as described above. Connect
the amplifier output to a small full range speaker. Turn the amplifier level controls full down and turn the amplifier on.
Turn up the level control until you hear a signal through the speaker. Alternate between adjusting R8 for the lowest output
signal and increasing the input control until you have the level control full. There should be very low output from the
amplifier if any is detected at all.

Dissipation Threshold

Gate Voltage Clamp

Q17 (Q16)

Maximum power delivery, within the output MOSFET ratings for power, voltage and current, is ensured by our NOMAD
(NOn-Multiplying Advance Decision, patent pending) circuit. The device current and voltage are electrically measured
and the drive voltage is clamped to limit the power demand when the operation exceeds the device dissipation limits.
NOMAD is comprised of separate, symmetrical sections which monitor operating conditions of the positive and
negative output devices.

The voltage drop across R67 (R68) is proportional to, and represents, the positive output current (the negative circuit
components are shown in parentheses). The voltage drop across R43 (R54) is a shaped function of the positive output
device voltage. The emitter to collector voltage of Q11 (Q13) is constant and supplies the circuit reference voltage. When
the sum of these voltages exceeds 0.6V, Q10 (Q12) is turned on. If the condition persists long enough to charge C11
(C12), Q17 (Q16) is activated and clamps the output gate voltage.

The NOMAD circuit can be disengaged by removing D1 (D2). This allows amplifier operation without protection.

CR2

The thermal protection is activated, and shuts down audio operation, when the amplifier heatsink reaches an
excessively high temperature. The voltage divider R22 and R23 establishes the reference voltage on pin 5 of U5B. The
control voltage, on pin 4 is established by the voltage divider TS1 and R25. TS1 is a NTC (Negative Temperature
Coefficient) thermistor, mounted on the heatsink. As TS1 warms and the resistance falls, the voltage on pin 4 rises. When
the voltage on pin 4 exceeds the voltage on pin 5, the output on pin 2 goes low, shutting down the Soft Start switch Q1
and lighting the THERMAL indicator.

LED CR4.

AMPLIFIER MODULE REPLACEMENT

The amplifier modules have been designed to eliminate the need for a special workplace if a field exchange becomes
necessary. All wire connections are made with quick connect terminals so soldering is not necessary. The following
tools are needed to disassemble the amplifier:

Allen wrench, 9/64
Phillips screwdriver, #1 tip
Thin nose pliers

WARNING: Only a competent technician should attempt the following procedure.

1. Disconnect the power to the amplifier before proceeding

2. Locate the 9/64 Allen head screws on the top edge of the amplifier between the heatsink fins. Remove these and
the Phillips head screws holding the input jacks on the rear panel. Lift the rear of the cover and remove it from the
amplifier. Take the knobs off the level controls.

3. Remove the 9/64 Allen screw located behind the rack ears and the two 9/64 screws on the bottom edge of the
heatsink. This frees the module from the chassis and it can be lifted clear.

4. Unplug the gray Mono cable connecting the two modules. Disconnect the red and black output wires and the orange
transformer secondary wires from the PC board.

5. Prepare a new Channel 1 module for installation by setting the NORMAL/Bridged MONO switch to the default
position according to the arrow marked on the PC board. Prepare a Channel 2 module by duplicating the switch
setting of the module which was removed.

6. Install the new module and check the position and alignment of the LEDs. Replace the level control knob and check
its alignment while securing the module.

7. After the module is secured, reconnect the wires according to the following chart:
