The Kopul high-performance passive direct box converts an unbalanced, high-impedance source to a balanced, low-impedance signal for mixers, audio interfaces, sound cards, and PA systems. It is designed for single-channel guitar, bass, keyboard, and DJ mixer applications in live-sound and recording environments.
- Flexible routing: Connect the source to the 1/4-inch TS input, route the parallel 1/4-inch thru to an amplifier, and send the balanced 3-pin XLR output to a mixing console or audio interface.
- Level matching: Select 0, -20, or -40 dB attenuation to accommodate instrument signals and hot DJ mixer outputs.
- Noise control: Engage the ground-lift control to help reduce hum and noise caused by ground loops.
- Passive operation: Solid-state circuitry requires no battery, phantom power, or AC adapter.
- Durable compact housing: Metal construction supports dependable stage, studio, rehearsal, and mobile use.
- Signal direction: The XLR connector is an output for feeding a mixer or audio interface and is not intended as an input for re-amping.
The Kopul high-performance passive direct box converts an unbalanced, high-impedance source into a balanced, low-impedance signal for connection to a mixing console, audio interface, sound card, or PA system. Its single-channel design is suited to electric guitar, bass, keyboard, and DJ mixer setups, with a 1/4-inch TS input, parallel 1/4-inch thru for an amplifier, and 3-pin XLR balanced output. Selectable 0, -20, and -40 dB attenuation helps manage different source levels, while the ground-lift control helps minimize hum caused by ground loops. Passive solid-state operation requires no battery or external power, and the compact metal housing supports live, studio, rehearsal, and mobile recording use.
