Unbalanced to Balanced Research - This website explain how to create a DI box, and some of the principle of converting an unbalanced signal to a balanced one. However I need to convert a balanced signal to an unbalanced input (unfortunatly). - Notes about ground loops and audio conections - more about balanced wiring. - possible solution

PRE-AMP Research

When i first realise i would need a preamp to get the microphone signal to line level for my interface (Behringer UCA202),  I initially thought i would use a LM358. However upon more research i found that although this would be adequate a more appropriate intergrated circuit would be the NE 5532, which is a high performance low noise operational amplifier.

Low noise integrated circuit:

Old Circuit Design -
New Circuit design with NE5532 8 pin DIL IC -

Consideration to the potential of need two preamps with phantom power to support condenser microphones:

-power supply-


This is my blog for my final year project at the university of the west of england, and its main purpose is to aid in my research for the project.

My aim for my project is to build a drum trigger hardware module accomp
anied with software that is completely usable in a studio situation.
The target user of my project would be for someone who wants to record a usable drum track but does not have the acoustic environment in which to record to an acceptable standard (e.g. a home studio situation).
