DMP3 Operation

A preamp is a necessary component of any signal chain, when a microphone, guitar pickup or other instrument needs an increase in gain to “line level.” The DMP3 will perform that role in your signal chain. The drawing below shows the DMP3 in use with a computer sound card, which in this case is the Delta 66 from M-Audio.

It is conceivable that once the DMP3 is attached to your system and powered up, you will be plugging and unplugging different microphones and instruments. Follow this simple procedure, making sure that the gain controls on the DMP3 are at their lowest levels when attaching or changing mics or instruments.

1.Plug in the 9v "wall wart" power supply into the wall receptacle, and the other end into your DMP3 9v power jack.

2.Make the necessary connections from the outputs of the DMP3 to the inputs of your computer sound card, mixer (use the line level inputs), or sound system’s power amp. NOTE: If your target device accepts a balanced signal either on a 1/4” TRS or XLR jack, use a TRS plug (tip-ring-sleeve, typically a stereo plug) on the outputs of the DMP3. If your target device accepts only an unbalanced line in, then use a ‘TS’ plug (tip-sleeve, i.e. a standard guitar cable). Check the documentation of your sound card or other receiving device if you are unsure. When possible, always use the balanced outputs as this will provide a quieter and hotter signal.

3.With all volume controls at their lowest settings, turn on your DMP3, then your sound system.
