Thank you for viewing! This is an active direct box from Klark Teknik. I purchased it urgently for live use about twice before, but I haven't used it since, so I'm putting it up for sale. I have confirmed that it produces sound. In my opinion, there may be some minor scratches, but it's only been used a few times indoors, so it's clean. However, it's a used item, so please understand this before purchasing. The original box and manual are included. The following is automatically entered by AI: Equipped with a PAD switch, it achieves clean signal transmission. - Model Name: DI 10A - Type: Active Direct Box - Input Terminals: UNBAL, INPUT - Output Terminals: BAL, OUTPUT - PAD Switch: 0, 20, 40 - Power: ON, LIFT, POWER, EARTH
