Thank You and congratulations on your purchase of the HAFLER TRM10s/TRM12s reference monitor, the world's finest
brand in professional audio equipment.
The TRM10s (Trans• ana Reference Monitor) is an amplified 10" subwoofer monitor. The TRM12s is an amplified 12"
subwoofer monitor. Both models offer unmatched quality and performance in a truly professional grade product. The
TRM10s/TRM12s 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 TRM10s/TRM12s 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
signals can be fed into the amplifier via Balanced XLR jacks (where long cable runs are used) or into standard Un-
Balanced 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 TRM10s 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
distortions 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 TRM12s features a 12" (305mm)
low frequency transducer made with the same cellulose fibre cone and santoprene rubber surround. The 12" trans-
ducer features a 2.5" (63.5mm) 4-layer copper voice coil wound on an aluminum voice coil former driven by a 102 oz.
magnet.
Both the TRM10s and TRM12s 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
(MaximumEfficiencyHeatSink Application)MEHSAis aproprietaryprocess thatyieldsup to5times betterheattransfer
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 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, 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 a 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 aluminum
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 distortion
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 subwoofer's
low frequency information with high frequency information pro-
duced by additional reference monitors. Aligning both signals will
insure that both low and high frequencies arrive at the listening
position at the same time. This eliminates the possibility of acousti-
cal 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)
application. 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
forward (FIG. 2). In either application keep the subwoofer cabinet at least 5" (12.7 cm) away from any wall.
INSTALLATION
FIG. 1
Downward Firing FIG. 2
Forward Firing
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 f3 of 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 f3 of 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 determine which type of
bass response works best in your home theater.

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 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 conductors, 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.

OPERATION
AUTO TURN-ON / SLEEP MODE
The TRM10s/TRM12s subwoofers automatically turn on when they sense an input signal. When the signal being fed to the
TRM10s/TRM12s 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
The Input Sensitivity is used to match the TRM10s/TRM12s with signal levels from a variety of mixing consoles. The Input
Sensitivity uses a potentiometer to match input levels over a 30dB range and is variable from +1dBu 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 +1dB 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 variable
potentiometer to set the cutoff point anywhere between 40Hz
and 140Hz. When the control is set to its full CLOCKWISE
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
frequency reference monitors. Mismatching the crossover
points can cause dips or peaks 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
frequency 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.
