The Donner Special-I is a compact passive direct box that is perfect for connecting unbalanced sounds sources, like guitars, basses, and keyboards directly to mixing consoles or other XLR devices. It is small enough to fit inside your gig bag or instrument case.
The design of this DI Box is simple. Connect your unbalanced signal to the parallel input. Attach the parallel output to your on-stage amplifier if desired. The XLR balanced output can then be fed to the mixing board directly without having to mic your amplifier. You can also choose not to plug into an amplifier and use the sound directly through the mixing console. The signal conversion is done by the custom-made Donner LAB-S1 transformer, which performs the impedance matching and balances the signal.
- Input (1/4in TS): Unbalanced, Hi-Z input connection for musical instruments.
- Parallel Output(1/4in TS): Connects the instrument to an on-stage amplifier if desired.
- OUTPUT (XLR): Balanced mic-level output. Connect this to your audio interface or a mixing console using a high quality XLR cable.
- GND LIFT(ground lift) switch: Reduce hum and buzz caused by ground loops if any occur. Otherwise, disengage the switch or you may lose sound.

CUSTOM MADE LAB-S1 TRANSFORMER
The Donner LAB-S1 transformer is magical in its ability to handle extreme signal levels with a natural compression that is pleasing to the ears. The transformer also helps eliminate hum and buzz caused by ground loops by isolating the input from the output. This is made even better with a ground lift switch that lifts pin-1 on the XLR for quiet, professional results.
High Sound Quality & Low Noise
Plug your musical instruments into the Special- I and it will smooth out the peaks and warm up your tone with a vintage vibe. The compact design makes it perfect for traveling between gigs. Send the thru signal to your amp and the output to the PA system. Transformer isolation eliminates nasty hum and buzz caused by ground loops.
