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.

Active di box diagram.

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. The new fe2 features a through jack for patching to an amp or speaker. The biggest difference between an active di and a passive di is that an active di includes a preamplifier. 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.

As shown here the di box is actually splitting the signal between the on stage amp and the pa system. Our popular di box kit is back with expanded features and three transformer options. Much obliged al brady. 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.

The active di box may still use a balancing transformer at the output as this provides better electrical isolation than electronic balancing solutions.

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.
