An Audio Standard for Going from Instrument to Mixer
The direct box is an essential tool for musicians and sound engineers: it converts an instrument signal into a balanced XLR output, better suited for long cable runs and mic/line inputs on a mixer or interface. With its Thru output and ground lift, this model aims for easy integration in live and studio setups.
Who Is It For and What Are Its Uses?
This DI is intended for guitarists and bassists who want to send a reliable signal to the front of house, a recorder, or an audio interface, while retaining the ability to feed an amp via the Thru output. It is also useful whenever you need to secure the level and reduce unwanted noise in a stage setup.

True to description and use.
I use it with a passive guitar and bass... each connected to an effects pedalboard (so it becomes an active source).
It does what is intended: maintaining the level up to the console and isolating the ground loops.Automatically translated

Good surprise, extraterrestrial quality/price ratio. After going to the bench, I confirm that I bought passive DIs that were much more expensive and not as efficient. 5 stars excluding minimum taxes.

Questions frequently asked
Is the Mackie MDB-1P suitable for connecting a bass to a mixer?
This direct box features a 6.35 mm jack input and a balanced XLR output to send a bass signal to a mixer, recorder, or interface. The Thru output on a 6.35 mm jack allows maintaining a connection to an amplifier.

The -15 dB pad reduces the input level of high-output sources to preserve headroom before clipping. It can be engaged when the signal from a guitar or bass is likely to overload the DI input.
How can ground hum be eliminated with this DI?
The ground lift breaks a ground loop that may cause hum. The balanced XLR output also helps reject interference on long cable runs.

The instrument input is a 6.35 mm jack. A 6.35 mm jack Thru output and a main balanced XLR output are available.
