Passive pickups on a guitar emit a high-Z signal, whereas gear that receives this signal such as mic preamps and mixing desks require a low-Z signal. The signals need to be at low-Z for recording and live purposes, thus the DI box ensures you get the right level signal for recording and the PA system.
What is a DI input?
Direct boxes are often referred to as “DI” boxes. This stands for “Direct Injection” as their main purpose is to convert unbalanced and/or high impedance instrument signals into a format suitable for direct connection to a mixing console’s mic input – without the use of a microphone.
Is Hi Z the same as DI?
A nice onboard Hi-Z input is a good substitute for an inexpensive (vanilla) DI box. It’s not a substitute for a specialty DI box that significantly enhances the signal. This is so very true.
What is the purpose of using a DI box?
The primary function of a direct box is to convert the unbalanced high-impedance signal from an instrument to a balanced low-impedance signal that is compatible with a P.A. or recording system.
What does Hi-Z mean?
high impedance
Hi-Z (or High-Z or high impedance) refers to an output signal state in which the signal is not being driven. The signal is left open, so that another output pin (e.g. elsewhere on a bus) can drive the signal or the signal level can be determined by a passive device (typically, a pull-up resistor).
What is HI-Z used for?
The Hi-Z switch raises the impedance of the line input to be suitable for passive guitar and bass. This feature only works when the Line switch is engaged. Pressing HI-Z without LINE will have no effect.
What’s the point of a DI box?
How does a passive DI box work?
A passive DI uses an internal transformer and requires no power source for it to work. Just plug the instrument into the input of the direct box and a mic cable into the output; the mic cable then connects to the mixer’s XLR mic preamp inputs.
Can I plug my amp into my audio interface?
Summary. Yes, you can plug an amp in an audio interface, provided the amp has a line out. It is advisable to connect the line out to the line input on the audio interface. Also, keep the speaker cabinet connected if you are using an amp head.
When to use a DI box for recording?
DI boxes are used when you need a direct connection of a guitar or a bass to professional recording equipment via the microphone input. Quality DI boxes can make a night and day difference in recording quality sometimes. So, it is worth to give one a try.
What are the inputs and outputs of a di?
At their most basic, DIs are equipped with at least one input and two outputs; one being a thru-put for an instrument amplifier, and the other for input to a PA system. The output of a DI is mic level, which allows it to be connected to the microphone inputs of a mixer.
Why do you need a passive DI box?
The result is that signal is both impedance matched for a standard mic pre and free from ground hum originating at the input stage. Passive DIs are ideal for instruments with strong outputs, and both their low cost and durability make them the most popular kind of direct box.
Why does DI box attenuate the signal level?
The latter functionality explains why DI box attenuates the signal level. The balanced cables are normally plugged into the microphone inputs. They are very sensitive and a signal level from a guitar pickup can easily clip the console input. Thus, in order to stay on the safe side, the direct box attenuates the signal.
