OPERATION:
Connect your inputs as the silk screening indicates. Connect the output XLR to a
microphone level input on the unit you are sending the mixed signal to. Adjust the level
control to the appropriate level for the source signals (RCA or 3.5mm) to match the
microphone level as desired. Switch the desired signals to be sent out of the DB227.
- You can use both the RCA and 3.5mm inputs at the same time, but please be aware
that you will not be able to attenuate the signals independently.
- The ground lift has no proper setting it will be dierent for every application. Choose
the setting that generates the best results (least amount of noise).
- The level control is designed to control only the level of the source input (RCA or
3.5mm). To match the level of the microphone that is passing thru the DB227.
