Bolanle DI/LI Passive Direct Box / Line Isolator

Some signal problems are not “EQ problems”, they’re routing problems. The Bolanle DI/LI is a passive direct box / line isolator designed to help you handle both high-impedance instrument signals and low-impedance line-level signals, with a switchable mode for each job.

With transformer-isolated balanced output, ground lift, pad, and DI/LI mode switching, it’s a practical utility box for stage rigs, studios, playback systems, and instrument setups where you need cleaner signal transfer and less hum.

Features

• Passive DI / LI switchable design (Direct Injection or Line Isolator mode)

• Transformer-isolated output for cleaner signal transfer and lower hum risk

• Converts 1/4" unbalanced input to balanced XLR output (DI use)

• -15dB pad (DI mode) for hot input signals

• Sum switch for combining left/right thru signals to a single amplifier (per listing)
