AC LINE

The TRM10.1 /TRM12.1 operate from a 115 VAC/60Hz power line. The TRM10.1SCE/TRM12.1SCE operate from a 230 VAC 50/60Hz power line. Connection is made by a 16-gauge, IEC Type 320, grounded line cord. For safety considerations only a properly grounded (earthed) receptacle should be used. If a grounded circuit is not available, do not break off the ground pin; use the proper adapter plug for a two wire receptacle with the grounding plug suitably connected to earth ground.

IMPORTANT: The power line fuse is mounted on the rear panel. If this fuse blows, replace it only with the same type and rating as indicated in the parts list.

LED INDICATOR

Amplifier operation is monitored internally and has a status LED. This indicator can be used for system troubleshooting. The LED will illuminate GREEN if signal is present at the subwoofer's input. The LED will turn off and the amplifier will go into sleep mode if signal is not present.

We recommend initially breaking in the subwoofer for approximately 8 hours with musical information to establish the mon- itor's natural bass response. To achieve the best sonic performance and image stability from the internal amplifier, we recom- mend letting it warm up for 1 hour before beginning any critical listening.

CLEANING & MAINTENANCE

There is no requirement for regular maintenance on the electronic components of the monitor. If the cabinet or woofer becomes soiled, it can be cleaned using a damp, soft cloth. If the monitor is located in a particularly dusty environment, clean- ing the inside with compressed air or vacuuming every 18 to 24 months is sufficient.

TRM12.1, TRM10.1 specifications

The Hafler TRM12.1 and TRM10.1 are professional studio monitors engineered to deliver exceptional sound reproduction within various audio environments. As part of Hafler's prestigious legacy in audio equipment, these monitors cater to audio professionals seeking durability, accuracy, and an impressive performance for mixing, mastering, and high-fidelity playback.

One of the standout features of the TRM12.1 is its 12-inch woofer, which provides a deep and powerful bass response, ensuring that low frequencies are rendered with clarity and precision. This is especially important in genres that emphasize bass, such as electronic music and hip-hop. The TRM10.1, on the other hand, is equipped with a slightly smaller 10-inch woofer, making it an ideal choice for smaller spaces or for users who prefer a more compact solution without sacrificing sound quality.

Both models utilize advanced drive technologies and high-quality components. The tweeter in each speaker is designed for wide dispersion and low distortion, allowing for a balanced high-frequency response that is essential for detailed mixing tasks. This design ensures that the monitors provide a natural and transparent sonic experience, making it easier for audio professionals to make critical listening decisions.

The unique enclosure design of the TRM series minimizes resonance and acoustic interference, which helps to achieve a cleaner and more precise sound stage. The cabinets are constructed from high-density materials to reduce vibration, providing a stable platform for the drivers to perform optimally.

Connectivity is another strong point of the TRM12.1 and TRM10.1. Both monitors feature a variety of input options, including balanced XLR and TRS connectors, making them versatile for integration into different studio setups. This flexibility allows users to connect the monitors to various types of audio interfaces and mixers easily.

User control is facilitated by adjustable rear bass and treble EQ controls, empowering users to tailor the sound to better fit their room acoustics. This feature is particularly useful in situations where room reflections may affect sound quality.

In conclusion, the Hafler TRM12.1 and TRM10.1 studio monitors represent a blend of advanced technology, robust construction, and user-friendly features. Whether in a professional mixing environment or a home studio, these monitors provide the fidelity and reliability that audio professionals depend on to bring their creative visions to life. With their impressive performance and thoughtful design, the TRM series continues to uphold Hafler's tradition of excellence in audio engineering.
