2.3 Room Correction

The KH 750 AES67 is designed to work seamlessly with Neumann's Automatic Monitor Alignment (MA 1) software. This software, often bundled with the subwoofer, uses a measurement microphone to analyze your room acoustics and apply precise DSP corrections to optimize the subwoofer's frequency response. This process ensures a flat and accurate listening environment.

1. Connect the measurement microphone to your system.
2. Run the MA 1 software and follow the on-screen instructions for acoustic measurement.
3. The software will calculate and apply the necessary corrections to the subwoofer's DSP.
4. Once applied, these settings are saved directly to the subwoofer, eliminating the need for continuous software operation.

3. Operacinis

3.1 DSP Functionality

The integrated DSP allows for fine-tuning of the subwoofer's performance. This includes fourth-order DSP crossovers for seamless integration with your main monitors and various acoustical controls to adapt to different room characteristics. These settings are typically managed via the MA 1 software during the room correction process.

3.2 Bass Manager

The unique 2.0/0.1 Bass Manager provides flexibility for various system configurations. It allows you to manage how the low-frequency content is routed between the subwoofer and your main stereo monitors, ensuring optimal bass extension and clarity without muddying the overall sound.

3.3 Nuotolinis valdymas

The KH 750 AES67 can be controlled remotely, offering convenience for adjustments without needing to access the unit directly. Refer to the specific remote control instructions for pairing and functionality.

4. Priežiūra

To ensure the longevity and optimal performance of your Neumann KH 750 AES67 subwoofer, follow these maintenance guidelines:

• Valymas: Use a soft, dry cloth to clean the exterior surfaces. Avoid abrasive cleaners, solvents, or waxes.
• Vėdinimas: Užtikrinkite pakankamą oro srautą aplink įrenginį. Neužblokuokite ventiliacijos angų.
• Aplinka: Operate the subwoofer in a stable environment, away from extreme temperatures, humidity, and direct sunlight.
• Galia: Disconnect the power cable from the wall outlet before cleaning or if the unit will be unused for an extended period.

5. Problemų sprendimas

If you encounter issues with your KH 750 AES67 subwoofer, refer to the following common troubleshooting steps:

• Nėra galios: Check the power cable connection and ensure the power outlet is functional. Verify the power switch on the subwoofer is in the 'On' position.
• Nėra garso: Confirm all audio cables (analog or digital) are correctly connected. Check the input source and volume levels on your audio interface/monitor controller. Ensure the subwoofer's volume is not set to minimum.
• Iškraipytas garsas: Reduce the input level to prevent clipping. Check for loose cable connections. If using room correction, ensure the calibration is up-to-date.
• Uneven Bass Response: Re-run the Automatic Monitor Alignment (MA 1) software to recalibrate the subwoofer to your room acoustics. Adjust subwoofer placement if necessary.
• Connectivity Issues (AES67/Dante): Verify network cable connections. Check network settings and ensure proper IP configuration. Consult your network audio device manuals for specific troubleshooting steps.

If problems persist after attempting these steps, contact Neumann customer support for further assistance.
