5. Acoustic Tuning:
The rear panel features "ACOUSTIC TUNING" controls (HIGH and LOW) to adjust the frequency response to your room acoustics. Experiment with these controls to achieve the most balanced sound for your environment.
Operating
1. Power On/Off:
Use the POWER switch on the front panel of the main speaker to turn the monitors on or off. A blue LED indicator will illuminate when the speakers are powered on.
2. Volume Control:
Adjust the overall output volume using the VOLUME knob on the front panel. Start with a low volume and gradually increase it to a comfortable listening level.
3. Input Selection:
The monitors automatically detect active inputs. If multiple inputs are connected, the last active input will be prioritized. For Bluetooth, ensure your device is paired and playing audio. For wired connections, ensure the source device is active.
4. Headphone Output:
A 3.5mm headphone jack is available on the front panel. Connecting headphones will mute the speaker output, allowing for private listening.
Maintenance
Cleaning:
Wipe the exterior of the monitors with a soft, dry cloth. Do not use abrasive cleaners, waxes, or solvents as they may damage the finish. Avoid spraying liquids directly onto the speakers.
Storage:
If storing the monitors for an extended period, disconnect them from power and store them in a cool, dry place, preferably in their original packaging to protect them from dust and physical damage.
