The dbx Di4 is a versatile 4-channel unit designed for various audio applications. Here's a breakdown of its key features and recommended uses:



    Signal Conversion: The Di4 converts unbalanced signals into balanced outputs, making them suitable for use with mixers, PAs, recording consoles, and other professional audio equipment. It helps eliminate noise and interference commonly associated with unbalanced connections.



    Multi-Channel Stereo Line Mixer: In addition to signal conversion, the Di4 functions as a multi-channel stereo line mixer. This allows you to consolidate multiple audio sources, such as keyboards, samplers, and modules, into a single rack unit. Each channel can be adjusted independently, and the mixer provides independent XLR balanced outputs for front-of-house engineers and stage monitoring.



    Headphone Output: The Di4 also features a headphone output, providing convenient monitoring options for performers or technicians.



Recommended Uses:



    Studio: The Di4 can be used in studio setups for connecting various audio sources and ensuring balanced signals for recording and mixing.

    Tour: Its rugged construction and versatile functionality make it suitable for live touring applications where space and signal management are critical.

    Portable: The compact size and multiple features of the Di4 make it ideal for portable setups, such as mobile recording rigs or small live performances.



Usage Guidelines:



    DI Box: Connect unbalanced signals via 1/4-inch jacks to the channel inputs on the front panel. Use XLR balanced cables to connect to your destination equipment. Adjust signal strength with the 20dB pad and eliminate ground loop hum with the earth lift switch if necessary.

    Line Mixer: Mix volume and pan of all input signals to a stereo pair of RCA connections on the rear. Connect the RCA stereo master outputs to your desired destination and adjust individual volume and pan controls for each channel on the front panel.



In summary, the dbx Di4 offers flexible signal management and mixing capabilities, making it a valuable tool for various audio professionals and applications, including studio work, live performances, and portable setups.
