Operation
1. Power On/Off
Locate the power switch on the rear panel of the monitor. Flip the switch to the "ON" position to power on the monitor. Flip to "OFF" to power down. It is recommended to power on your monitors after your audio source and power them off before your audio source.
2. Volume Adjustment
The volume knob on the rear panel allows you to adjust the output level of the monitor. Start with a low volume setting and gradually increase it to a comfortable listening level.
3. Acoustic Adjustments
The Classic 5 features High Frequency (HF) and Low Frequency (LF) level adjustment controls on the rear panel to tailor the monitor's response to your listening environment and personal preference.
- HF Level Adjust: Adjusts the high-frequency output. Options typically include -2dB, -1dB, FLAT, and +1dB.
- LF Level Adjust: Adjusts the low-frequency output. Options typically include -2dB, -1dB, FLAT, and +2dB (KRK Bass Boost).
Experiment with these settings to achieve the most accurate sound for your room. The "FLAT" setting provides the most neutral response.
Maintenance
Cleaning
To clean the monitor's plastic enclosure, use a soft, dry, lint-free cloth. For stubborn dirt, a slightly damp cloth with mild soap can be used, followed by drying with a clean cloth. Avoid using abrasive cleaners, solvents, or waxes, as these can damage the finish. Do not spray liquids directly onto the monitor.
Storage
If storing the monitors for an extended period, place them back in their original packaging in a dry, temperature-controlled environment.
