The Digiflex DSPDI Stereo Passive Direct Box is a rugged dual‑channel DI designed to convert unbalanced stereo signals into isolated balanced outputs, making it ideal for connecting keyboards, audio interfaces, mixers or other line‑level sources to professional consoles while eliminating ground loops and noise. Key Features: Accepts stereo inputs via dual ¼″ jacks, RCA connectors or a 3.5 mm mini‑TRS, offering flexible connectivity. Dual balanced XLR female outputs with full transformer isolation (1:10) to reject common‑mode noise and hum. Stereo/mono sum switch allows combining channels into one mono output when needed. Ground lift switch helps eliminate hum caused by ground loops in live or installed setups.
