DI Box

Dual-Channel Active Direct Box
The ADI-2 is a high-performance dual-channel active DI (Direct Injection) box designed for guitars, basses, keyboards, electronic instruments, and stereo audio sources. Equipped with a ultra-low-noise analog amplification circuit, it ensures pristine, transparent impedance matching and signal balancing when feeding signals into mixing consoles, audio interfaces, and professional PA systems. The ADI-2 features two 1/4" inputs, two 1/4" parallel Thru outputs, and two balanced XLR outputs, making it versatile for both stage and studio applications. It operates entirely on +48V phantom power without the need for batteries. Comprehensive controls include a -15 dB input attenuation switch (PAD), an 80 Hz high-pass filter (HPF), a Ground Lift switch, and a side-mounted 180° polarity reverse switch for the right channel.

Passive Dual-Channel Di Box
The PDI-2 is a dual-channel passive DI box designed for instruments, keyboards, electronic instruments, and stereo audio sources. Built with a transformer-based passive circuit, it converts unbalanced signals into balanced XLR outputs for connection to mixers, audio interfaces, and professional sound systems. With 2 × 1/4" inputs, 2 × 1/4" Thru connections, and 2 × XLR outputs, the PDI-2 supports practical signal routing for stage and studio setups. It requires no battery, phantom power, or external power supply, and features a 0 dB / -15 dB input pad and Ground Lift switch for flexible operation.

Single-Channel Active DI Box
The DI-108 is a single-channel active DI box designed for live sound and studio recording. It converts high-impedance, unbalanced audio signals into low-impedance, balanced outputs, helping reduce noise interference over long cable runs. A built-in output isolation transformer, combined with a Ground Lift switch, helps minimize ground-loop hum for reliable connections between audio devices. Equipped with 1/4" and XLR inputs, the DI-108 accommodates electric guitars, basses, keyboards, DJ mixers, and other audio sources. Two -20 dB attenuation switches provide up to -40 dB of input attenuation to help prevent distortion from high-level signals. The 1/4" parallel LINK output allows simultaneous connections to a mixing console and an instrument amplifier or monitoring system, offering flexibility for different stage and studio setups. The DI-108 supports 18–48V phantom power or 9V battery operation, featuring a battery ON/OFF switch and automatic power switching when phantom power is available to conserve battery life. Battery operation also enables use with equipment that does not provide phantom power. A rugged metal housing makes it suitable for stage and studio environments.
