Auto TURN-ON / Sleep Mode, Input Sensitivity

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.

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.
