Excerpt: I use 2 DI400P boxes for my keyboard to improve sound quality Pros: Low cost, good sound quality, which is significantly better than without DI boxes. Metal case. Cons: TS jack. Will attempt to replace them with good Neutrik jacks in the future

Pros: Accurate Controls, Compact, Easy To Use, Excellent Sound, Versatile
Excerpt: We use this for live sound for a local church. We use a few direct boxes for our sound. We needed another one since we have had a few musicians that needed them for instruments. This direct box works fine and does what you need a direct box to do.
Pros: Compact, Easy To Use, Lightweight, Versatile
Excerpt: I use it to change an unbalanced signal to a balanced signal, or in other words, a 1/4 inch cable into an XLR cable. A balanced cable carries signal much better than an unbalanced cable, especially over long distances.
Pros: Clear Sound, Compact, Easy To Use, Lightweight
Excerpt: We got ten Behringer DI-400P direct boxes for use at our international school in Thailand, and they are great! We use them for guitars, keyboards, hooking in computer audio, and converting long audio runs to low impedance. We often use the loopback jack to get a cleaner signal from the bass.
