Nastavení

The Behringer MicroHD HD400 is a passive device, meaning it does not require external power. Its setup involves integrating it into your audio signal chain to eliminate ground loop hum and noise.

Kroky připojení:

1. Identify the Source of Hum: Determine which part of your audio setup is introducing the hum. This is typically a ground loop issue between two connected devices.
2. Připojení vstupu: Take the 1/4" TRS output cable from the device that is feeding the signal (e.g., mixer, instrument, loop station) and connect it to the "INPUT 1" or "INPUT 2" jack on the HD400. For stereo signals, use both "INPUT 1" and "INPUT 2".
3. Připojení výstupu: Connect a 1/4" TRS cable from the corresponding "OUTPUT 1" or "OUTPUT 2" jack on the HD400 to the input of the next device in your audio chain (e.g., amplifier, PA system, recording interface). For stereo, use both "OUTPUT 1" and "OUTPUT 2".
4. Ověřte připojení: Ensure all cables are securely connected. The HD400 will automatically isolate the ground loop and convert unbalanced signals to balanced if necessary.

The compact size and passive nature of the HD400 allow for flexible placement within your setup, such as on a pedalboard or near the problematic audio connection.

Návod k obsluze

The Behringer MicroHD HD400 is a plug-and-play device with no user-adjustable controls. Once correctly integrated into your audio signal path, it operates automatically to eliminate hum and noise.

• No power supply is required for operation.
• The device functions as a passive ground loop isolator and signal balancer.
• Ensure proper cable connections as described in the "Setup" section for optimal performance.

The HD400 is designed for transparent operation, meaning it should not color or degrade your audio signal while effectively removing unwanted noise.

Údržba

The Behringer MicroHD HD400 requires minimal maintenance due to its passive design and robust construction.

• Čištění: K čištění vnější strany jednotky používejte měkký, suchý hadřík. Nepoužívejte abrazivní čisticí prostředky, rozpouštědla ani vosky, protože by mohly poškodit povrchovou úpravu.
• Skladování: Pokud přístroj delší dobu nepoužíváte, skladujte jej v suchém a bezprašném prostředí.
• Zacházení: While rugged, avoid dropping the unit or subjecting it to excessive force, which could damage internal components or connectors.
• Podmínky prostředí: Nevystavujte jednotku extrémním teplotám, vlhkosti ani přímému slunečnímu záření.

Odstraňování problémů

If you experience issues with your Behringer MicroHD HD400, refer to the following troubleshooting steps:

• Persistent Hum/Noise:
  • Ensure the HD400 is correctly inserted into the signal path between the two devices causing the ground loop.
  • Check all cable connections for looseness or damage. Try different cables if possible.
  • Verify that the hum is indeed a ground loop issue. The HD400 is designed for ground loop isolation, not other types of noise (e.g., RF interference, faulty equipment).
  • If using multiple devices, try isolating them one by one to pinpoint the exact source of the ground loop.
• Žádný zvukový signál:
  • Confirm that the input and output cables are connected to the correct jacks on the HD400 (e.g., Input 1 to Output 1, not Input 1 to Output 2).
  • Check the integrity of all audio cables.
  • Bypass the HD400 temporarily to see if the audio signal returns. If it does, the issue might be with the HD400 unit itself or its connections.
• Signal Degradation (Loss of Highs/Lows):
  • The HD400 is designed to be transparent. If you notice significant signal degradation, ensure you are using high-quality 1/4" TRS cables.
  • Verify that the input signal level is appropriate. While passive, extremely low or high impedance mismatches could theoretically affect performance, though this is rare for a ground loop isolator.

If these steps do not resolve the issue, contact Behringer customer support or a qualified technician.
