Bolanle Passive DI Box — 1-Channel (DB1) or 2-Channel (DB2), 1/4" to XLR

Send your guitar, bass or keyboard cleanly to the mixer or PA with the Bolanle passive DI box. It converts an unbalanced 1/4" instrument signal to a balanced XLR output for long, noise-free cable runs, and the ground-lift switch kills hum and buzz from earth loops. No power needed.

Highlights

• Instrument to XLR: converts unbalanced 1/4" signals to balanced XLR for clean, long runs.
• Ground lift & phase: ground-lift kills hum; a 0/180° phase switch fixes cancellation.
• Attenuation switch: 0 / -20 / -40 dB pads for instruments, line gear or speaker outputs.
• Thru / parallel out: feed your amp and the PA at the same time.
• Choose 1 or 2 channels: DB1 (single) or DB2 (stereo / dual).
