Thank You and congratulations on your purchase of the HAFLER TRM6 reference monitor, the world's finest brand
in professional audio equipment.
The TRM6 (Trans•ana Reference Monitor) is a bi-amplified, two-way near field monitor offering unmatched
quality and performance in a truly professional grade product. The TRM6 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 TRM6 amplifiers utilize our trans•ana circuit topology employing MOSFETs in the output stage resulting in
superior sound quality.
An active 4th order Linkwitz-Riley crossover sends frequencies above 3.2kHz to a 35 watt amplifier driving
a proprietary wave guide tweeter, and frequencies below 3.2kHz to a 50 watt amplifier driving an 6"
transducer. The high frequency channel features up to ±4dB of Treble shelving, while the low frequency channel
features up to ±4dB of Bass shelving. In addition, the low frequency channel includes an active 2nd order
subsonic filter selectable to limit harmful frequencies below 30Hz or 60Hz. Monitoring
the status of both channels 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 soundwaves from planar to spherical which result in excellent high frequency dispersion and coherent on-axis
frequency response. The low frequency transducer is a proprietary 6.5" (165mm) steel basket woofer utilizing a
20 mil polypropylene cone with a 20 mil dust cap. The suspension consists of a nitrile rubber surround and an
extended collar flat spider. The motor is constructed from a 1.25" diameter voice coil on an anodized aluminum
former with an extended vented pole piece. The 33 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 firing radiused Aerovent for reduced turbulence. The outside features
a semi-gloss finish and includes a rubber pad on the underside to control vibration.

MEHSA
(Maximum Efficiency HeatSink Application) MEHSA is a proprietary process that yields up to 5 times better
heat transfer than traditional FET mounting techniques using the exact same components. A multi-layer
insulated metal substrate operating with minimal thermal resistance spreads heat both downward and
outward to quickly dissipate heat from each device across the heatsink. This process combined with our DSM
technology and MOSFET devices allow us to squeeze more watts per cubic inch from every output device as
well as provide consistent thermal stability.
The Way The Old Way
THE RESULT: Better reliability through faster heat dissipation.
Trans•ana
Trans•ana (TRANSconductance Active Nodal Amplifier) is a circuit that allows the audio signal to pass
through the amplifier at low voltage. The signal is directly level-shifted to the fixed high voltage rails via a
pair of driver transistors. Signal linearity is assured by an active node formed by the driver transistors at
ultrasonic frequencies. This allows amplifier performance similar to Trans•nova which is highly stable and
linear while utilizing the advantages of a non-floating power supply.
THE RESULT: An extended frequency band width accurately supplied to the output stages of the amplifier.
MOSFET Devices
HAFLER is one of the few manufacturers in the sound community to utilize MOSFET devices in both the
power supply and output stages. MOSFET (Metal Oxide Semiconductor Field Effect Transistor) devices offer
several important inherent advantages over the 30 year old technology of bi-polar design. These advantages
include: thermal stability, fast switching speed, ultra low output impedance and wide bandwidth linearity.
In addition, MOSFETs operate very similarly to vacuum tubes in that they are more linear than bipolar
transistors. However,MOSFETscandeliverthemidrangeclaritywithoutthelimitationsoftransientresponse
and high frequency phase shifting normally associated with tube operation.
THE RESULT: Thermal stability, fast switching speed, ultra low output impedance and wide bandwidth
linearity.

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.”
Shielded Magnet
A shielded magnet is used to reduce the radiation of high-strength magnetic fields from the woofer's motor
assembly. Suppression is accomplished by attaching a “bucking” magnet to the motor assembly in order to
keep stray leakage 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 com-
puter monitors.
THE RESULT: Prevents distortion in TV and computer monitors.
Phase Coherent
Each monitor is Phase Coherent in order to assure proper arrival times of all frequencies in the near field
environment. 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 39µs 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 frequency 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
performancein complex acoustic environments. 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 horizontal 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.

The unbalanced input uses a conventional RCA phone jack. Move the input switch ON (-->) to use this jack. The
balanced input jack is an XLR plug. The XLR jack is connected according to the IEC and AES standard. Move the input
switch OFF (<--) to use this jack.
DETERMINING 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 minimum and maximum height spanning between the
tweeter dome and woofer dust cap.

XLR WIRING CONFIGURATIONS
Using the balanced XLR input is recommended for installations where long cable runs are used or when the potential
for stray electromagnetic fields from other wires exists. There is a balanced and unbalanced method in which the XLR
inputs can be used. The first method is an XLR Balanced Input using 3-conductor cable. The balanced signals carried
on pins 2 and 3 are equal in amplitude and opposite in phase. Pin 1 is the ground and shield. In this configuration,
noise common on both phases of signal are effectively "canceled" out. The second method is an XLR Unbalanced Input
using 2-conductor cable with the signal carried in the center conductor and the ground carried on the shield. Many
popular mixers use unbalanced outputs and can be used with the XLR balanced input. However, in this type of
configuration we recommend using twisted pair cable or short cable length to prevent residual ground noise.
