Know before you buy
No, the DJDI is a passive device. It does not require batteries or external power, making it a simple 'plug-and-play' solution for your audio setup.
The ground lift switch is used to eliminate unwanted hum or buzz caused by ground loops. If you hear a persistent low-frequency noise in your signal, toggling this switch often resolves the issue.
Yes, the DJDI is perfect for that. It converts the unbalanced 1/4-inch signals from your consumer devices into balanced XLR signals, which allows you to run long cables to a mixer without picking up interference.
The volume control acts as an attenuator, allowing you to lower the input signal level before it hits the mixer. This is particularly useful if you are plugging in high-output devices that might otherwise cause clipping or distortion.
Absolutely. The DJDI is built with a sturdy steel housing designed to withstand the wear and tear of live sound environments and frequent transport.
