UNIKA PRO-ONE
UNiKA PRO-ONE is a professional passive DI box designed to connect electronic equipment 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-ONE 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.
