Thank You and congratulations on your purchase of the HAFLER TRM8 reference monitor, the world's finest brand
in professional audio equipment.
The
TRM8
(

onitor) is a bi-amplified, two-way near field monitor offering unmatched
quality and performance in a truly professional grade product. The TRM8 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.

The TRM8 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 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 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 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 8" (200mm) diecast 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 1.5" diameter voice coil on an anodized, aluminum
former with an extended vented 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
firing radiused Exoport for reduced turbulence. The outside features a semi-gloss finish and includes a rubber pad
on the underside to control vibration.
