UNiKA PRO TWO - Passive two-channel DI Box

UNIKA PRO-TWO

UNiKA PRO-TWO is a professional passive two-channel DI box designed to connect electronic devices with line-level outputs such as keyboards, drum machines, Drum Pads and DJ Equipment to balanced low impedance inputs such as those from mixers, external microphone preamps, active speakers and sound cards. Since PRO-TWO is a passive device, no batteries or other power supplies are required. Note: For instruments and devices without line-level output, please use UNiKA PRO-148 or PRO-248.

UNiKA PRO-ONE and UNiKA PRO-TWO can be used to safely connect and electronically isolate a variety of audio devices. For additional safety, PRO-ONE and PRO-TWO pass no phantom power (48V) and can also be used "in reverse" for unbalanced line outputs with a suitable inverse XLR adapter.

PRO-TWO has a pair of built-in UNiKA-PRO™ EI30A10E 1+1: 1+1 isolation transformers, which have a special copper foil layer and a dedicated grounding layer, enabling this device to restore high signal-to-noise ratio and dynamic sound and eliminate unnecessary losses due to high-frequency interference, grounding interference and potential differences can be avoided.
