Active di box diagram.
And unlike a reamping box where a budget transformer performs admirably a direct box is a sensitive application that demands a high quality transformer.
In terms of sound quality the only component that matters in your passive di is the transformer.
Most of us as sound types know that we use a di box to interface a line level or instrument level signal with a microphone preamplifier.
Our popular di box kit is back with expanded features and three transformer options.
Bb d1 active di operation overview.
This active di does not have a negative feedback which is very beneficial for the sound quality but the downside of such approach is the necessity to sort the j fets in ranges by their idss maximum idle current and to pair with different source resistor rs values for each range.
A direct box is a must for recording studio applications or sound amplification applications when you need to interface an unbalanced audio source such as a.
Build your own boutique passive direct box.
Much obliged al brady.
The fe2 s studio quality electronics are housed in an architectural aluminum enclosure that s rugged enough for the road.
I want to output to a pa amp with an xlr cable about 3 meters long to save me from having to.
This type of di was originally designed to provide an extra gain to boost the weak output of some passive single coil pickups but the extra gain is great for driving long cable runs and many modern active dis include advanced signal.
The biggest difference between an active di and a passive di is that an active di includes a preamplifier.
The pz di is a high performance specialized active direct box designed to accommodate acoustic and orchestral instruments with a selectable input impedance that can accommodate magnetic pickups or piezo transducers and a variable low cut filter.
Active usually uses an operational amplifier integrated circuit to generate the proper plus and minus outputs or inputs and is powered by a battery or external source such as phantom power.
The active di box may still use a balancing transformer at the output as this provides better electrical isolation than electronic balancing solutions.
I m going to go for an active di box.
The new fe2 features a through jack for patching to an amp or speaker.
As shown here the di box is actually splitting the signal between the on stage amp and the pa system.
A di box i suppose a good place to start would be understanding exactly what a di box does.
However because of the relatively high cost of good transformers the majority of the more affordable active di boxes are transformerless.
