Best overall: Pyle Direct Injection Box

Buy on Amazon

The look and feel of this boxes are consistent with the high quality we're used to from the rest of Pyle's lineup. The world over, the ot-2 provides superior signal isolation from local ac and rf hum, and the ultimate in impedance matching. It is built to be used with signals alike for example stereo keyboards or similar. They also come in handy hooking a guitar or bass directly into a mixer by balancing the high output of the guitar or bass into a lower input signal that the mixer can cleanly use. They also allow you to set input levels via a switch just in case your input is hot.

This device also has some ground lift switches that can prevent ground loops. It's ultra-compact and housed in a tough, road-ready metal case. These are great for a permanent installation, or for musicians who don't do a whole bunch of traveling. It's inexpensive and works great as advertized.

• Clean strong signal and versatile with ground lift and input pads
• Excellent to isolate noise and hum from external source
• A must tool for any working musician or audio tech

Best With No AUDIBLE noise: Radial Engineering Direct Injection Box

Buy on Amazon

The radial engineering direct injection box might be a relatively new release, but it's still nothing short of impressive this year. This unit produces a clean signal, is easy to use, and is just as rugged as everything else they make. It works equally well for any instrument level 1/4 inch output from guitar, bass, piano, keyboard, etc. It is quiet and clean and doesn't color the sound. They naturally smooth out the transients that sometimes sound harsh on piezos, and they can handle huge amounts of signal before distorting, so they're well suited for the Godin Multiac series of guitars.

One thing that's great with this is being able to plug a guitar tuner into the THRU connection. It is perfect for live or studio performances.

• Good sound quality, minimal coloration, handy features
• Just clean signal and playing freedom in a well-constructed, small package
• Lot of satisfied buyers

Best For Ipad: ART Direct Injection Box

Buy on Amazon

The art direct injection box should be able to handle its purpose and duties with ease. When you connect the DI Box to a PA amplifier that provides phantom power for mics, the DI box can be powered by that phantom power. It is used to power the di box and internal amplifiers. It makes it "powered" and the signal going to the mixing board is boosted or hotter. It is also good to use for having a local amp (fed from the front side passthrough jack) as well as feeding a combined PA amp.

It is running off of phantom power, and is off when the unit is inactive. It's also good to use for having a local amp (fed from the front side passthrough jack) as well as feeding a combined PA amp.
