This is a very good stereo direct box, it features a quite flat response curve and some useful additional functions: indeed a -20dB pad for attenuating strong line signals, a ground lift switch in case of ground loops, but also the possibility to send one mono source input to two balanced outputs, or to sum the two input channels. Inputs may either be 2 mono jack 6.35mm, 2 XLRs, or one 3.5mm stereo jack.
It has a two LEDs indicating that correct phantom power is present for each channel. Sturdy enough, withstanded any scene that we encountered as of today. It is not the cheapest DI box, but in our opinion, its excellent quality is worth the price.
