Nobsound NS-05P PRO Bi-Directional XLR RCA Converter User Manual

pengenalan

The Nobsound NS-05P PRO is a versatile bi-directional audio converter designed to bridge the gap between consumer Hi-Fi equipment and professional audio systems. It facilitates seamless conversion between RCA (unbalanced) and XLR (balanced) signals in both directions, ensuring high-fidelity audio transmission with minimal interference. This manual provides detailed instructions for the setup, operation, and maintenance of your NS-05P PRO converter.

Ciri-ciri Utama

• Bi-Directional RCA & XLR Conversion: Transforms RCA to XLR and XLR to RCA, offering full flexibility for various audio setups.
• True Balanced Circuitry: Converts RCA signals to true balanced XLR, effectively reducing hum, buzz, and ground loop noise for a cleaner sound.
• Dual-Path with Independent Control: Features two independent conversion paths, each with its own volume knob for precise level matching. Both paths can operate simultaneously.
• Wide Audio Compatibility: Integrates with mixers, audio interfaces, active studio monitors, power amplifiers, DACs, and more.

• Butang Kuasa: Menghidupkan atau mematikan unit.
• Volume Knob (RCA input → XLR output): Adjusts the output level for the RCA to XLR conversion path.
• Input RCA: Connect RCA source devices for conversion to XLR output.
• Keluaran XLR: Connect XLR receiving devices from RCA input.
• Input XLR: Connect XLR source devices for conversion to RCA output.
• Keluaran RCA: Connect RCA receiving devices from XLR input.
• DC 5V (≥1A) Power Interface (USB Type-C): Connect the provided USB cable to a 5V power source.
• Terminal GND: Connect to an earth ground or metal chassis of other equipment to reduce hum or noise.

Persediaan

Follow these steps to set up your Nobsound NS-05P PRO converter:

1. Sambungan Kuasa: Connect the supplied USB cable to the USB Type-C power interface on the NS-05P PRO. Connect the other end of the USB cable to a DC 5V (≥1A) power adapter (not included) or a suitable USB power source. The unit requires power to function.
2. Audio Input/Output Connections:
   • RCA to XLR Conversion: Connect your RCA source device (e.g., CD player, PC) to the RCA Input ports on the left side of the unit. Connect your XLR receiving device (e.g., active speaker, amplifier) to the XLR Output ports on the left side.
   • XLR to RCA Conversion: Connect your XLR source device (e.g., mixer, audio interface) to the XLR Input ports on the right side of the unit. Connect your RCA receiving device (e.g., preamppenguat, amplifier) to the RCA Output ports on the right side.

   Penting: The NS-05P PRO does not support RCA-to-RCA or XLR-to-XLR connections. Ensure connections are made correctly for the desired conversion path.

3. Pembumian (Pilihan tetapi Disyorkan): If you experience hum or background noise, connect a wire from the GND terminal on the NS-05P PRO to a real earth ground or to the metal chassis of another audio component in your system.
4. Hidupkan kuasa: Press the power button to turn on the NS-05P PRO.

Arahan Operasi

Once the NS-05P PRO is set up and powered on, you can begin using it to convert audio signals.

1. Pelarasan Kelantangan: Use the dedicated volume knobs for each conversion path (XLR input → RCA output and RCA input → XLR output) to adjust the audio level. These knobs act as mini-preamps, allowing for precise level matching between your connected devices.
2. Operasi serentak: The two conversion paths are fully independent. You can use both RCA to XLR and XLR to RCA conversions simultaneously without interference.
3. Gain Characteristics: Note that the maximum gain differs between modes:
   • XLR to RCA Mode: Provides a maximum gain of +5dB when the volume knob is turned to maximum, resulting in a potentially louder output.
   • RCA to XLR Mode: Provides a maximum gain of 0dB.

Penyelenggaraan

To ensure the longevity and optimal performance of your NS-05P PRO:

• Pastikan unit bersih dengan mengelapnya dengan kain lembut dan kering. Elakkan menggunakan bahan kimia yang keras atau pembersih yang kasar.
• Do not expose the unit to excessive moisture, direct sunlight, or extreme temperatures.
• Pastikan pengudaraan yang betul di sekeliling unit untuk mengelakkan terlalu panas.
• Kendalikan dengan berhati-hati untuk mengelakkan kerosakan fizikal.

Menyelesaikan masalah

If you encounter issues with your NS-05P PRO, refer to the following common problems and solutions:

• Unit is not working / No signal output:
  • Ensure the NS-05P PRO is properly powered by a DC 5V (≥1A) supply via the USB Type-C port. Check if the power supply is functional.
  • Verify that the RCA and XLR ports are connected correctly for the desired conversion path (RCA IN → XLR OUT or XLR IN → RCA OUT). Incorrect connections (e.g., RCA-to-RCA or XLR-to-XLR) will result in no signal.
• Hum or background noise:
  • Connect a wire from the GND terminal on the NS-05P PRO to a real earth ground or to the metal chassis of another piece of equipment in your audio chain. This can help eliminate ground loop issues.
  • Ensure all audio cables are of good quality and properly shielded.
• Output volume difference between RCA-to-XLR and XLR-to-RCA modes:
  • This is normal behavior due to differing gain structures. XLR-to-RCA mode has a maximum gain of +5dB, while RCA-to-XLR mode has a maximum gain of 0dB. Adjust the independent volume knobs to achieve desired levels.
