are important and should be followed.
4. FOLLOW INSTRUCTIONS
All operating and use instructions are important and should be
followed.
5. HEAT
The equipment should be kept away from areas of high temper-
ature, i.e., heater vents, radiators, stoves/ovens, fireplaces, etc.
6. VENTILATION
The equipment should be used in an area suitable for proper ven-
tilation. Care should be taken not to impede airflow in and
around the cabinet.
7. WATER AND MOISTURE
The equipment should not be used in or around water, such as a
bathtub, sink, or swimming area. Also, the equipment should not
be used in areas prone to flooding, such as a basement.
8. POWER SOURCES
The equipment should be connected only to a power source of
the same voltage and frequency as that listed on the rear panel
above the power cord entry point.
9. POWER CORD PROTECTION
Power cords should be arranged so 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 it is not in danger of being pinched or cut,
as in under a rug, around a tight corner, etc.
10. POWER CORD GROUNDING
The power supply cord is of a three wire grounded type, designed
to reduce the risk of electric shock sustained from a live cabinet.
It is assumed to be of suitable length for most uses of the equip-
ment. The use of extension cords and power strips is discouraged
unless they are of suitable rating to deliver the required total cur-
rent for safe operation of all connected equipment. Furthermore,
extension cords or power strips must provide the same three wire
grounded connection. It is important that the blades of the equip-
ment’s plug be able to fully insert into the mating receptacle.
Never remove the round grounding pin on the plug in an attempt
to mate to a two wire ungrounded receptacle: use a grounding
adaptor with the grounding tab or wire suitably connected to
earth ground.
11. NON-USE PERIODS
During periods of extended non-use, the power cord should be
unplugged from the power source.
12. CLEANING
The equipment should be cleaned only as detailed in the operat-
ing instructions.

Thank You and congratulations on your purchase of the HAFLER TRM8.1 reference monitor, the world's finest brand in
professional audio equipment.
The TRM8.1 (Trans•nova Reference Monitor) is a bi-amplified, two-way near field monitor offering unmatched quality
and performance in a truly professional grade product. The TRM8.1 is great for Professional Studios, Digital Work
Stations, Broadcast Booths, and Home Project Studios.
Although we realize a professional such as yourself already knows a thing or two about pro audio, we urge you to read
this manual to at least humor our technical writer. For ease of use, this manual is organized into three main sections:
Installation, Operation, and Service Reference. “Installation”covers the set-up of your new HAFLER equipment in the
system. “Operation”covers the controls and how to use them for optimum performance. “Service Reference”contains
field service information useful for technicians and engineers.
TECHNICAL DESIGN FEATURES
The TRM8.1 amplifiers utilize our trans•nova circuit topology employing MOSFETS in the output and power supply
stages combined with our DIAMOND transconductance driver stage resulting in superior sound
quality.
An active 4th order Linkwitz-Riley crossover sends frequencies above 2.5kHz to a 75 watt amplifier driving a proprietary
wave guide tweeter, and frequencies below 2.5kHz to a 150 watt amplifier driving an 8" transducer. The high frequen-
cy channel features up to ±4dB of Treble shelving, while the low frequency channel features up to ±4dB of Bass shelv-
ing. In addition, the low frequency channel includes an active 2nd order subsonic filter to limit harmful frequencies
below 30Hz. Monitoring the status of each high and low frequency channel is done with an LED indicating Power On,
Clipping and Thermal.
The high frequency transducer is a Ferrofluid cooled 1" (25mm) soft dome hemispherical tweeter utilizing a rigid but
lightweight silk diaphragm. A Phase Lens and axis-symmetric exponential waveguide improve the transition of sound-
waves from planar to spherical which result in excellent high frequency dispersion and coherent on-axis frequency
response. The low frequency transducer is a proprietary 8" (200mm) diecast basket woofer utilizing a 20 mil polypropy-
lene cone with a 20 mil dust cap. The suspension consists of a nitrile rubber surround and an extended collar flat spi-
der. The motor is constructed from a 1.5" diameter voice coil on an anodized, aluminum former with an extended vent-
ed pole piece. The 44 oz. ferrite magnet is magnetically shielded to suppress stray leakage flux to only 4" –well within
the confines of the monitor's walls making it great for use near CRT monitors.
The cabinet is made from acoustically dead 19mm MDF, internally lined with damping material and features a rear fir-
ing radiused Exoport for reduced turbulence. The outside features a semi-gloss finish and includes a rubber pad on the
underside to control vibration.

DIAMOND (U.S. patent 5,673,000)
DIAMOND (Dynamically Invariant AMplification Optimized Nodal Drive) is an important advance in circuit
design which reduces high frequency distortion. DIAMOND combines the linearity of Class A operation with the
current headroom of a Class B system by operating the MOSFET driver stage with 20dB or more of current head-
room, whereas traditional drivers have only 6dB of current headroom. The result is a dramatic reduction in high
frequency distortion, combined with improved ultrasonic stability.
THE RESULT: Colorless high frequency reproduction and greater inherent stability.
AMPLIFIER
trans•nova (U.S. Patent 4,467,288)
The trans•nova (TRANSconductance NOdal Voltage Amplifier) is a patented circuit that allows the audio signal to
pass through the amplifier at low voltage. Each amplifier channel utilizes its own “fully floating”power supply and
is configured to increase power gain. The increase in power gain allows the driver stage to operate at a lower volt-
age. A low voltage drive stage is the same principle used in high quality preamplifiers to produce high linearity and
wide bandwidth.
The resulting design utilizes an output stage with a simpler gain structure and a shorter signal path than conven-
tional high voltage (bi-polar) designs. The number of stages is reduced from five or more to three. The output stage
is further refined into a trans-impedance stage (current to voltage converter) to achieve a short loop (fast) negative
feedback. The output stage is driven cooperatively by a transconductance stage (voltage to current converter).
THE RESULT: Superior sound quality, greater efficiency and higher reliability.

TWEETER
Wave Guide
The wave guide is a proprietary axis-symmetrical form of horn mounted to the tweeter to increase efficiency. The
wave guide improves the transition of sound waves (from planar to spherical) smoothly from the throat of the wave
guide to the mouth. The unique shape and smooth surfaces improve the tweeter's off-axis frequency response as
well as provide coherent on-axis response.
THE RESULT: Improves dispersion for a wider “sweet spot.”
WOOFER
Shielded Magnet
A shielded magnet is used to reduce the radiation of high-strength magnetic fields from the woofer's motor assem-
bly. Suppression is accomplished by attaching a “bucking”magnet to the motor assembly in order to keep stray leak-
age flux within the monitor cabinet. This type of shielding prevents color and
image distortion when placing the woofer in close proximity to direct view
(CRT) television receivers and computer monitors.
THE RESULT: Prevents distortion in TV and computer monitors.
CABINET
Phase Coherent
Each monitor is Phase Coherent in order to assure proper arrival times of all frequencies in the near field environ-
ment. This is accomplished by aligning both transducer's voice coils on a common ZDP (Zero Delay Plane) axis.
The cabinet baffle positions the woofer forward and the waveguide displaces the tweeter back with an additional
43ms delay in the high frequency amplifier to precisely “tweak”the tweeter onto its ZDP axis. This allows the
acoustic center, located midway between the high and low frequency transducers, to coherently deliver a flat fre-
quency and phase response around the crossover point.
THE RESULT: Delivers a flat frequency and phase response.

LOCATION
The location of your reference monitors in addition to the acoustics of the listening room will influence the system frequency
response. In the near field environment, our ears are more sensitive to direct sound rather than the reverberation of sound.
Below are some recommendations for the initial set-up which may help you optimize performance in complex acoustic envi-
ronments. In any configuration, keep the rear of the monitor at least 5" (12.7cm) away from any wall or obstruction to
reduce excessive boundary “loading” of the woofer vent and to optimize heat sink cooling.
INSTALLATION
Aiming the monitors directly forward (Fig. 1) may cause response problems resulting in inadequate stereo imaging. Aiming the
monitors toward you and spaced equally like a triangle (Fig. 2) provides the best imaging and produces the flattest frequency
response.
If you frequently move your chair from side to side in front of your mixing console, positioning the tweeter and woofer in hor-
izontal alignment (Fig. 3) can create complex lobing patterns. Minimizing this effect can be achieved by placing the tweeter
and woofer in vertical alignment (Fig. 4). If it is essential to position the monitors horizontally, place them with the tweeters
toward the inside.

ACOUSTIC CENTER
Finding the “Acoustic Center”is accomplished by positioning the monitors so
coherent arrival of the transducers occurs at ear level. The Acoustic Center is
located 3 to 4 feet in front of the monitor, measuring perpendicularly from the
center point of the cabinet (midway between the woofer and tweeter). Our
tests have shown that a flat phase and frequency response occurs just above
and below the Acoustic Center with the maximum and minimum height span-
ning between the tweeter dome and woofer dust cap.
MOUNTING
The monitor may be mounted on a wall or ceiling, using suitable mounting hardware. The base of the monitor includes mount-
ing inserts designed for use with “OmniMount Systems®” or equivalent mounting products1.
If you mount the monitors to a wall or ceiling, you must take special care to mount them securely to prevent them from falling
and causing damage or injury. Make sure that the mounting hardware (fasteners and connectors) and the surface you are
mounting to are each capable of securely holding the monitor in place even if it is struck or moved. Make sure the mounting
hardware, fasteners, and connectors are rated for an object at least as heavy and bulky as the monitor.
Use good judgement and common sense throughout all phases of the installation and use mounting techniques appropriate
for the surface you select. Use the mounting hardware according to the manufacturer's recommendation and provide adequate
reinforcement to the monitors if needed. Do not mount the monitor only to drywall –make sure the fasteners are secured to a
stud, joist, or other structural support. If appropriate, use a secondary support for added safety –a properly installed safety cable
provides an extra margin of safety and can be installed out of sight easily.
