Aktiivinen DI-box Klark Teknik DI 10A 1-kanavainen 48V fantomijännitteellä

The Active DI box Klark Teknik DI 10A 1-channel with 48V phantom power is a compact direct input converter designed to connect instruments and line-level sources to mixing consoles and PA systems. It converts unbalanced instrument signals to a balanced low-impedance output, provides impedance matching and accepts 48V phantom power for active circuitry. The device is intended for both live sound and studio applications where clean signal transmission and ground loop mitigation are required.

Advantages

The DI 10A offers low-noise active circuitry that preserves signal clarity across long cable runs and reduces interference. Its ability to accept 48V phantom power eliminates the need for batteries, while balanced output protects the signal from external noise. The single-channel form factor is straightforward to integrate into existing signal chains and live rigs.

Suitable for

• Connecting electric guitars, basses and keyboards to mixing consoles
• Feeding line-level sources and electronic instruments into PA systems
• Studio tracking where impedance matching and noise reduction are required
• Live sound setups that need balanced signals over long cable runs

Key specifications

• Single-channel active DI design
• Accepts 48V phantom power for internal active electronics
• Converts unbalanced instrument/line input to balanced low-impedance output
• Low-noise circuitry for clean signal transmission
• Compact enclosure suitable for stage and studio use

How to use

Connect the instrument or line-level source to the DI 10A input using a standard instrument cable. Provide 48V phantom power from the mixing console or a phantom power supply to power the active circuitry. Use the balanced output to connect to the console’s microphone/line input via an XLR cable. Ensure the mixing console’s input gain is set appropriately and check for a clean, balanced signal; adjust levels at the console rather than the DI box. For ground loop prevention, verify the system grounding and use the DI’s grounding features if available.

Recommendations

Use the DI 10A with quality instrument and XLR cables to maintain signal integrity. When possible, supply phantom power from the console to avoid battery changes. For best results in live environments, place the DI box near the instrument to minimize unbalanced cable length and route balanced runs to the console.
