On board DI wiring help..


Recommended Posts

Hi, I've have a older overwater bass that's had the active preamp replaced with a emg system. The bass sounds great but... As a result of this, the xlr di socket (which seems to come as standard fitment on this overwater model) has been disconnected. So I've be looking to rewire the di back up but can't seems to find any info how to do this, any thoughts? Many thanks

XLR outputs generally provide a balanced line level signal that can be plugged directly into a mixing desk. The EMG preamp only delivers a standard unbalanced instrument level output. For the XLR to work properly the onboard preamp would need to have the necessary DI circuitry to provide a balanced line level output.

Or a transformer, which you might be able to drive off the normal output.

Good point, the preamp output will be low impedance which just needs a passive DI transformer. Something like a Jensen JT-DB-E - [url="http://www.markertek.com/product/jt-db-e/jensen-jt-db-e-direct-box-transformer"]http://www.markertek.com/product/jt-db-e/jensen-jt-db-e-direct-box-transformer[/url]. Here are some notes on how to build a DIY passive DI which might help - [url="http://www.diyrecordingequipment.com/blogs/news/15851820-how-to-build-a-boutique-passive-di"]http://www.diyrecordingequipment.com/blogs/news/15851820-how-to-build-a-boutique-passive-di[/url]
