future reference.
3. HEED WARNINGS
All warnings on the equipment and in the operating instructions
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.
13. OBJECT AND LIQUID ENTRY
Care should be taken so that objects and/or liquids, such as clean-
ing fluids or beverages, are not spilled into the enclosure of the
equipment.
14. DAMAGE REQUIRING SERVICE
Hafler equipment should be serviced by qualified service person-
nel when:
A. The power supply cord or plug has been damaged, or
B. Objects have fallen onto, or liquid has been spilled into the
equipment, or
C. The equipment has been exposed to rain, or
D. The equipment does not appear to operate normally or
exhibits a marked change in performance, or
E. The equipment has been dropped, or the enclosure has
been damaged.
15. SERVICING
The user should not attempt to service the equipment beyond that
which is described in the operating instructions. All other service
should be referred to qualified service personnel.
16. CARTS AND STANDS
The equipment should be used with carts or stands only of suffi-
cient strength and stability for the use intended. An equipment
and cart combination should be moved with care. Quick stops
and starts, excessive force, and uneven surfaces may cause the
equipment and cart combination to topple.
The lightning flash with arrowhead symbol within an equilateral trian-
gle is intended to alert the user to the presence of uninsulated "dan-
gerous voltage" within the product's enclosure, that may be of suffi-
cient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to
alert the user of the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.

INTRODUCTION
Thank you and congratulations on your purchase of the HAFLER TRM10.1/TRM12.1 reference monitor, the world's finest
brand in professional audio equipment.
The TRM10.1 (Trans•ana Reference Monitor) is an amplified 10" subwoofer monitor. The TRM12.1 is an amplified 12"
subwoofer monitor. Both models offer unmatched quality and performance in a truly professional grade product. The
TRM10.1/TRM12.1 are 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 TRM10.1/TRM12.1 monitors utilize a specially designed amplifier featuring our innovative trans•ana circuitry.
This topology, with its unique input-to-output configuration (derived from our patented trans•nova circuit), employs
MOSFETs in both the power supply and output stages that result in superior sound quality.
The amplifier features an auto turn-on/off circuit that eliminates the need for a conventional power switch. Input sig-
nals can be fed into the amplifier via Balanced XLR jacks (where long cable runs are used) or into standard unbal-
anced RCA jacks (where short cable runs are used). Each pair of inputs is combined into a mono-summed signal
before being fed into a 4th order Linkwitz-Riley low-pass crossover, variable from 40Hz–140Hz. If selected, the signal
is then fed into the Phase Warp that allows the phase of the signal to be adjusted at 90˚, 180˚, or 270˚increments.
The TRM10.1 features a 10" (254mm) low frequency transducer with a cone made from cellulose fibre. A santoprene
rubber surround that is immune to temperature fluctuations controls woofer damping and reduces 2nd harmonic dis-
tortions for a very wide and flat frequency response. The transducer also features a 2" (51mm) 4-layer copper voice
coil wound on an aluminum voice coil former and is driven by a 30-oz. magnet. The TRM12.1 features a 12"
(305mm) low frequency transducer made with the same cellulose fibre cone and santoprene rubber surround. The 12"
transducer features a 2.5" (63.5mm) 4-layer copper voice coil wound on an aluminum voice coil former driven by a

Both the TRM10.1 and TRM12.1 are downfiring subwoofer models and are vented using a radiused Aerovent for
reduced turbulence. The cabinet is made from acoustically dead 19mm MDF material and is internally packed with
damping material to eliminate internal resonance.

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
allows us to squeeze more watts per cubic inch from every output device as well as provide consistent thermal
stability.
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 tran-
sistors. 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: ther-
mal 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,
MOSFETs can deliver the midrange clarity without the limitations of transient response 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.

Woofer
Santoprene Rubber Surround
Santoprene is a very durable and temperature tolerant material which provides the consistent support necessary for the
linear motion of the speaker cone. In addition, the damping capabilities eliminate the transmission of sonic disturbances
between the cone and the frame of the speaker. This greatly improves the accuracy of the woofer's low frequency
response.
THE RESULT: Improves woofer's low frequency response.
Aluminum Voice Coil Former
The transducer's voice coil former is black anodized aluminum for highly efficient thermal transfer. Another method of
producing voice coils is with Kapton®formers. Although this material is very resistant to heat, any heat generated by
the transducer is "trapped" on the copper voice coil windings. HAFLER uses aluminum voice coil formers because alu-
minum acts like a "heat sink" and helps dissipate heat away from the voice coil. This allows winding high temperature
copper wire in multiple layers for improved efficiency.
THE RESULT: Improves power handling by efficiently dissipating heat.
Subsonic Filter
The TRM series uses a Subsonic Filter to prevent the woofer from reproducing inaudible frequencies. Subsonic
frequencies (known as infrasonic frequencies) are signals below the normal human hearing range and are generally
considered to be below 20Hz. The subsonic filter reduces the energy of these frequencies and restrains the woofer
from operating outside its optimum linear excursion. This type of electronic control eliminates the mechanical distor-
tion caused by a woofer traveling beyond its XMAX, improves power handling, increases reliability and improves sonic
performance.
THE RESULT: Improved power handling, increased reliability and improved sonic performance.
Phase Control
The Phase Control is used to align the arrival time of the sub-
woofer's low frequency information with high frequency informa-
tion produced by additional reference monitors. Aligning both sig-
nals will insure that both low and high frequencies arrive at the lis-
tening position at the same time. This eliminates the possibility of
acoustical cancellation and improves the reproduction of transients.
THE RESULT: Eliminates phase cancellation and improves transient
response.

LOCATION
The acoustic properties and size of the listening environment can drastically influence the SPL (Sound Pressure Level) and f3
(-3dB roll-off) of the subwoofer. However it's important to note that large or small acoustic spaces have little to no effect on
the subwoofer cone excursion & box "Q." For the most part, we'll discuss the optimum location for two different installation
methods: Studio Installation and Home Theater Installation.
STUDIO INSTALLATIONS
In studio installations, damping material is usually used on the walls and ceilings make the room “acoustically dead.”The
main monitors are typically located 3' to 6' from the mixing console and therefore considered a near field (close field) appli-
cation. In this type of anechoic environment, the subwoofer will tend to experience minimal "Boundary Loading" effects.
For studio installations, HAFLER recommends experimenting with different locations within the studio that minimizes rattles
or vibration of other equipment. You can fire the subwoofer downward (FIG. 1) or fire the subwoofer directly facing for-
ward (FIG. 2). In either application keep the subwoofer cabinet at least 5" (12.7 cm) away from any wall.

HOME THEATER INSTALLATIONS
Home Theater installations are typically medium sized
living rooms or game rooms that have large flat, uncov-
ered walls. Acoustics in this type of installation can have
a big effect on the SPL and f3of the subwoofer because
the walls are very reflective. The only elements in these
installations that acoustically "absorb" sounds are
furniture and carpet. Dramatic "Boundary Loading" can
be achieved by locating the subwoofer under a table,
next to a wall or in a corner (FIG. 4), thus increasing SPL
and lowering the f3of the subwoofer system. Locating
the subwoofer in the middle of the room or in a large
open area where there are few reflective surfaces will
cause a decrease in SPL and an increase in f3.
Experiment with different locations in the room to deter-
mine which type of bass response works best in your
home theater.

XLR WIRING CONFIGURATIONS
Using the XLR Balanced Input is recommended for installations where long cable runs are used or when the potential for stray
electromagnetic fields from other wires exists. There are balanced and unbalanced methods in which the XLR inputs can be
used. The first method is an XLR Balanced Input using 3-conductor cable with signal carried on the first and second conduc-
tors, equal in amplitude and opposite in phase, and the third conductor being a ground "drain". In this configuration, noise
common on both phases of the signal is 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 lengths to prevent residual ground noise.
INPUT SWITCH
The unbalanced input uses a conventional RCA phone jack. Move the input switch to RCA UNBALANCED 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 to XLR BALANCED to use this jack.
Unbalanced Input

OPERATION
AUTO TURN-ON / SLEEP MODE
The TRM10.1/TRM12.1 subwoofers automatically turn on when they sense an input signal. When the signal being fed to the
TRM10.1/TRM12.1 is turned off, the subwoofer's amplifier will turn off and go into "sleep mode." This feature eliminates the
inconvenience of operating a mechanical switch.
INPUT SENSITIVITY (GAIN)
The Input Sensitivity is used to match the TRM10.1/TRM12.1 with signal levels from a variety of mixing consoles. The Input
Sensitivity uses a variable potentiometer to match input levels over a 30dB range and is variable from 0dBu to -30dBu. The
numbers listed on the back panel indicate the input in dBu required to produce an output of 100dB SPL @ 1 meter. When the
control is set to its full CLOCKWISE position the monitor is matched to 0dB input level (the input circuit is less sensitive to the
amplitude of the input signal). When the control is set to its full COUNTER CLOCKWISE position the monitor is matched to
-30dB input level (the input circuit is more sensitive to the amplitude of the input signal).
LOW-PASS CROSSOVER
The Low-Pass Crossover is used to set the electrical cutoff
point of the subwoofer enclosure. The Crossover uses a vari-
able potentiometer to set the cutoff point anywhere between
40Hz and 140Hz. When the control is set to its full CLOCK-
WISE position the cutoff frequency is set to 140Hz Low-Pass.
When the control is set to its full COUNTER CLOCKWISE
position the cutoff frequency is set to 40Hz Low-Pass.
It is important to match the Low-Pass crossover point of the
subwoofer with the High-Pass crossover point of the high fre-
quency reference monitors. Mismatching the crossover points
can cause peaks or dips in the acoustical response.
Overlapping the crossover points (i.e., subwoofer at 60Hz
Low-Pass & high frequency monitors at 50Hz High-Pass) will
cause a peak between 50Hz and 60Hz. Underlapping the
crossover points (i.e., subwoofer at 40Hz Low-Pass & high fre-
quency monitors at 70Hz High-Pass) will cause a dip between
40Hz and 70Hz.
*This graph was generated by setting the variable crossover to
40Hz, 50Hz, 60Hz, 70Hz, 80Hz, 90Hz, 100Hz, 120Hz & 140Hz.
