    Low-Cut filter for the associated channel. Pressing and releasing to the ‘Out’ position disengages the filter. 7. Main Power LED: When the proper power supply is applied to the DMP3 and the Main Power switch is switched to the ‘On’ position, this LED will light, indicating that the unit is powered up.

    “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.
  • Page 6: Setting The Gain

    Setting the Gain The DMP3 provides up to 66dB of gain on the XLR and 1/4” high impedance inputs. Microphones and guitar pickups typically emit a low signal level, requiring a "pre-amp" such as the DMP3. Other instruments, such as keyboard sound modules, may also benefit from a little bit of punch from the DMP3.
  • Page 7: Vu Meters

    VU Meters The VU meters on the DMP3 are there to provide a visual reference to the signal at the output of the DMP3. They are, however, calibrated to correspond more closely to the level you will see on a recording device that has digital peak meters to show input level.
  • Page 8: Low-Cut Rumble Filter

    When foot movements, mic stand noise, or other low frequency sounds are unwanted, use the DMP3 Low-Cut filter to reduce or remove them. The DMP3 uses a 3-pole filter, attenuating the signal 75Hz and below at the rate of 18dB per octave.
  • Page 9: Balanced Vs. Unbalanced Outputs

    +4dB (nominal level) operating level, you should use TRS plugs on the outputs. An unbalanced line on the DMP3 outputs connects to a 1/4” TS (tip positive, sleeve ground) plug on a shielded cable with a single conductor, and is appropriate to use when your sound card or sound system accepts a 1/4”...
