2 introduction thank you for purchasing the m-audio dmp3 microphone/instrument pre- amplifier. The dmp3 gives you two completely independent channels of high gain, ultra low noise pre-amps in a sturdy desktop unit. Each channel provides low impedance microphone inputs on xlr connectors with optional...

3 front & rear panels front panel 1. Gain adjustment knobs: separate gain controls for pre-amp channels a and b adjust the output volume levels independently. Full counter- clockwise is the minimum gain position, while full clockwise is maximum gain. 2. Vu meters: these vu meters show output level, ...

Output jacks a and b: these 1/4” trs jacks are the main outputs for the pre-amps. Using a trs (tip-ring-sleeve...

5 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 t...

6 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 ...

7 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. Vu meters show an average ...

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. A “low cut” switch is provided on the fro...

Balanced vs. Unbalanced outputs a "balanced" line runs the signal on two wires of opposing polarity, as a ‘twisted pair’ surrounded by a grounded shield. Doing so, it can send a ‘hotter’ signal over a longer distance with less added noise. Using a trs (tip-ring-sleeve, sometimes referred to as “ster...
