Dual Channel Active DI Box – Balanced Guitar Signal Distributor
Dual Channel Active DI Box – Balanced Guitar Signal Distributor
Dual Channel Active DI Box – Professional Balanced Signal Distributor
Take your live performances and studio recordings to the next level with this Multi-functional Active DI Box Distributor. Designed for guitarists, bassists, keyboardists, and audio engineers, this dual-channel DI box converts high-impedance instrument signals to low-impedance balanced XLR outputs — delivering a clean, high-dynamic-range signal with virtually no unwanted noise or interference. Made in Mainland China.
Why You Need This DI Box
- Superior Noise Elimination: Ground isolation completely eliminates hum, while one-button attenuation clears up popping sounds and handles high-level inputs with ease.
- Universal Instrument Compatibility: Converts high-impedance (220kΩ) instrument signals to low-impedance (600Ω) balanced outputs, preventing low-frequency signal loss even over long cable runs.
- Dual Channel Expandability: Two independent unbalanced 1/4" TRS inputs split to two balanced XLR outputs. The CH2OUT (LINK) interface allows cascading multiple units to expand your channel count effortlessly.
- Flexible Dual Power Supply: Accepts both 18650 battery power and 18–48V DC phantom power — perfect for unpowered street gigs, emergency setups, or fully equipped professional studio environments.
- Studio-Grade Specs: Full 20Hz–20kHz frequency response, 109dBU dynamic range, and ultra-low 0.002% total harmonic distortion ensure transparent, faithful signal reproduction.

Frequently Asked Questions
Q: What is an active DI box and why do I need one for guitar?
A: An active DI (Direct Injection) box takes the high-impedance, unbalanced signal from your guitar or bass and converts it to a low-impedance, balanced XLR signal. This allows you to connect directly to a mixing console or PA system over long cable runs without losing low-frequency detail or introducing unwanted hum and interference. This dual-channel model handles two instruments simultaneously and can cascade with additional units for larger setups.
Q: Can I use this DI box without phantom power?
A: Yes! This active DI box supports both phantom power (18–48VDC, supplied via XLR from your mixer or interface) and an 18650 rechargeable battery. This makes it ideal for street performances, outdoor gigs, or any situation where a powered mixer isn't available.
Q: What instruments are compatible with this DI box?
A: The DI box works with any high-impedance instrument, including electric guitar, bass guitar, keyboards, acoustic-electric instruments, and more. Its 220kΩ input impedance ensures a pristine signal from virtually any instrument with a standard 1/4" output.
Q: How do I expand to more than two channels?
A: Use the CH2OUT (LINK) interface to daisy-chain (cascade) two or more DI box units together. This allows you to quickly and cleanly expand your channel count for larger live setups or multi-instrument recording sessions.
