INTRODUCTION

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.

TRM12S, TRM10S specifications

The Hafler TRM12S and TRM10S are two standout models in the world of professional studio monitors, designed to meet the demands of sound engineers, audiophiles, and music producers. Known for their exceptional performance and clarity, these monitors are integral to contemporary studio environments.

The TRM12S is equipped with a robust 12-inch low-frequency driver, ensuring deep bass response. This model has been tailored for larger spaces, delivering an impressive output that doesn't compromise on precision. It handles low-end frequencies adeptly, making it ideal for electronic music production, film scoring, and any genre where bass fidelity is paramount. The wide dispersion pattern of the TRM12S allows for a consistent listening experience across different positions in the room.

In contrast, the TRM10S features a slightly smaller 10-inch low-frequency driver, which is perfect for smaller studio setups or for users who prefer a more compact design without sacrificing sound quality. Despite the size difference, the TRM10S still offers profound bass response, making it versatile for various applications, from mixing to casual listening.

Both models utilize Hafler's proprietary technologies, including advanced, high-efficiency amplifiers that provide clean, high output with low distortion. This enables the monitors to produce a wide dynamic range, making it easier for sound engineers to make critical mixing decisions. The integrated DSP (Digital Signal Processing) allows for precise tuning of the audio output, which compensates for any deficiencies in the acoustics of the space.

Another key feature of the TRM series is the adjustable room compensation settings. This functionality empowers users to tailor their monitor settings based on room dimensions and placement, ensuring the optimal playback environment.

Moreover, both the TRM12S and TRM10S are built with durability in mind, featuring rugged enclosures that minimize resonance and vibration, resulting in a clearer audio reproduction. Their sleek design ensures they blend seamlessly into any studio décor, while providing professional-grade sound quality.

Overall, the Hafler TRM12S and TRM10S are designed for professionals seeking reliable, accurate monitors that excel in delivering unparalleled sound fidelity. Their combination of advanced technology, thoughtful features, and solid performance makes them a worthy investment for any serious studio setup.
