Radial JDI Duplex Passive Stereo Direct Box
The JDI Duplex is a high performance 2-channel passive direct box designed for enhanced connectivity for any application, with numerous input connector types and premium Jensen transformers for exceptional audio performance.
Features:
- Jensen transformer equipped passive DI
- Eliminates hum and buzz from ground loops
- 1/4″, 3.5mm, RCA, and XLR inputs to connect to any source
- Exceptional signal handling and noise rejection
- Turns the input & thru jacks into a passive mixer to sum stereo signals to mono
- Reduces the input sensitivity to allow high output signals from keyboards to be connected without distortion
- Mini TRS provides easy interface for laptops, tablets, smart phones and iPods
- Stereo inputs for -10dB consumer level devices such as CD players and other hifi devices
- Reverses pin-2 and pin-3 on the XLR output to help phase align the stage sound with the PA system
- Lifts the audio ground (pin-1 on the XLR output) to help reduce hum and buzz caused by ground loops
- Activates the +4dB line level balanced XLR input and disconnects the ¼" & RCA jacks
