dbx DI4 Active 4 Channel Direct Box with Line Mixer

Yes. The DI4 functions as a 4-channel line mixer with individual volume and pan controls on the front panel; mix all four inputs to a stereo RCA pair on the back, letting you consolidate multiple sources into a single balanced output to your mixer or interface.

The DI4 includes a 20dB pad switch on each channel to handle hot signals and an earth-lift switch to eliminate ground-loop hum, so you can adapt to problem venues or noisy signal chains without degradation.

Inputs are 1/4-inch unbalanced jacks; XLR balanced outputs are on the rear for each channel, a stereo RCA pair for the line-mixer sum, and a 1/4-inch headphone jack for monitoring.

Yes. At 3.85 lbs and 1U rack depth, it's compact and road-tough; low noise floor (0.0008% THD+Noise typical), transparent tone, and rugged construction make it ideal for gigging musicians and touring engineers.

Yes. The DI4 lets you set independent mixes via its four channel faders and pan controls—send the stereo RCA outputs to your monitor console and the individual XLR outputs to the main PA, each with its own balance.
