3. Operating the Monitor
3.1 Powering On/Off
Connect the provided power cable to the monitor and a suitable power outlet. Use the power switch located on the rear panel to turn the monitor on or off.
3.2 Adjusting Sound Characteristics
The HS5I features 'Room Control' and 'High Trim' switches on the rear panel. These controls allow you to adjust the monitor's frequency response to compensate for the acoustic characteristics of your room, ensuring a more accurate listening environment. Adjust the 'Level' knob to set the overall output volume.
3.3 Acoustic Design Features
The monitor incorporates a 2-way bass-reflex bi-amplified design with a 5-inch cone woofer and a 1-inch dome tweeter. Its low resonance enclosure design, achieved through a three-way mitered-joint technique, minimizes unwanted vibrations. Advanced noise reduction techniques, including controlling vortex at the speaker port, contribute to clear and accurate sound reproduction.
