![]() Well, if you want the ultimate in terms of its fidelity, an active box would be better because I do not guarantee the quality of small internal transformer. When comparing the circuit inside box and what is drawn here, it seem that the capacitor was drawn wrong on this circuit diagram (should be drawn between ground and signal going to transformer in parallel with 380 ohms resistor).īecause it is a simple passive DI, it can be used reverse in replace of an (expensive) re-amp box. The capacitor has marking 473J which means 47 nF. The lower resistor divider seems to use resistance values of 100 kohms and 380 ohms. Georgeaudio Millenium DI-E page has a circuit diagram of the unit (without componenet values):įor component values the resistor highest up is 1 kohms. Here is view what is inside it (was pretty easy to open with just opening two screws on bottom). I found this picture of newer version that shows the basic wiring of the unit at Audiofanzine review: some would argue that its unnecessary and you can get away with 2 jacks and a 10k pot in a box to attenuate the level. The box supports parallel connection to the speaker of a guitar amp. The box has two switches: ground lift and a switch to toggle between instrument/linelevel or speaker level input. Using a passive DI in reverse is a little better. Of course, it doesnt cost anything to try it. A DI box converts an unbalanced signal to a balanced signal. Also, it’s important to know that this device does the opposite of what a DI box does. That becomes apparent when you want to reamp your instruments. 2) You lose the galvanic isolation that the transformer provides, resulting again in noise and a likely ground loop. The reamp box just covers the sound but the important thing is what you can do with it. A second Jack socket in parallel allows the guitarist to plug in his amp. 1) Youre feeding a line level signal into your amp, usually resulting in noisy, thin sound. It is intuitive to use: You plug the guitar (or keyboard) jack on the base, and an XLR microphone cable with symmetrical signal and lowered impedance (microphone level) is fed to the console. ![]() Everything that is most basic, an entry, a low output Impedance, output (link), two buttons is called ground lift and instrument / speaker. This DI-box is economic doing its job well. No need to put more expensive for the majority of uses. This direct box is the cheapest passive exists at Thomann’s and perhaps anywhere. guitar box)ĭimensions (W x D x H): 100 x 130 x 40 mm With integrated switchable resistor network for extremely high input level (e.g. Here is technical information from Thomann Millenium DI-E page: Id just plug it in with the output way down first, and see if that is close enough. ART Dual RDB is a reamping DI box that offers you 2 separate channels with XLR and 1/4 TRS inputs and output with a full frequency range of 20 Hz 20 kHz. IT allows you to select to use the input with either an instrument or speaker level signal. Otherwise, theres no problem using only half of a balanced signal. The unit is passive and has ground and ground lift. It is pretty much the cheapest (around 12 Euros) DI box you can find that still does it’s job acceptably.
