4. FUNCTION OVERVIEW

INPUT (1)

 - Connect your instrument to the input of the Super Pro DI Box. Before making connections, make sure all volume levels are set 

to zero and the audio system is turned off. This will avoid any loud pops in your system that could cause damage. The Super Pro DI Box is a 
passive direct box: it does not require any power at all and will ignore the phantom power from your mixer, if activated.

THRU (2)

 - Connect to your on-stage amplifier, or a second mixer, recording apparatus, or powered monitor.

XLR TO MIC INPUT (3)

 - The balanced XLR output allows you to connect your Super Pro DI Box directly to a mixing console or sound card 

interface (either in live situations or in a recording studio). Simply connect a standard XLR cable from this output to the soundboard/mixing 
console/interface, or a snake connected to the board/console/interface..

GROUND LIFT SWITCH (4)

 - Occasionally when you’re playing live and using the XLR LINE OUT (3), the soundman will detect a hum from 

your amp’s signal. This is almost always due to a grounding problem related to your power source; you will likely eliminate this hum simply 
by flipping the GROUND LIFT (4) switch.

SPEAKER OUT / LINE SWITCH (5)

 - The Super Pro DI Box also allows you to send the amp’s output signal (instead of the instrument signal) 

to the PA or recording system, by placing the DI between the head and cabinet. Set the Speaker Out/Line Switch to “Speaker Out” and con-
nect the amp’s speaker output to the Input (1), and connect the Thru (2) output to the cabinet’s input. Before making this connection, make 
sure the amp is switched off, and check that the DI is switched to “Speaker Out” if you need to reduce the input level to prevent distortion 
from ultra-high output devices. 
Switch the DI to “Line” when connecting your instrument directly to the DI, or when connecting lower signal output devices to the Super 
Pro DI Box.
