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, calibrated to correspond to digital peak meters, where 0 VU is approximately 3dB to 6dB below clipping.

3.Clip LEDs: The Clip LED will light when that input signal is too strong and is about to distort, or “clip” (4dB below clipping). If this LED remains lit for more than a few moments, reduce the gain adjustment knob setting.

4.Low Cut LEDs: The "Low Cut" LED, when lit, indicates that the Low Cut Filter switch has been engaged for the corresponding channel.

5.Hi/Lo Gain Switch: This switch will set the “gain range” (or, amount of gain possible) for the corresponding input channel. Once the gain range is set, gain is adjusted via the Gain Adjustment Knobs. In the “Out’ position, the gain range is 32dB to 66dB (Hi gain). In the ‘In’ position, the gain range is 6dB to 36dB (Lo gain). See sections, “Setting the Gain” and “Hi/Lo Gain Switches” for more information.

6.Low Cut Filter Switch: Pressing and locking this switch to the ‘In’ position engages the 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.

8.Phantom Power LED: When lit, this LED indicates that phantom power has been switched on for both of the mic pre-amp channels.

9.Main Power Switch: This switch, when pressed and locked to the ‘In’ position, switches the DMP3 power on.

10.Phantom Power Switch: When this button is pressed and locked to the ‘In’ position, phantom power (48v) will be sent to both XLR In 1 and XLR In 2.

DMP3 specifications

The M-Audio DMP3 is a compact and versatile dual microphone preamp designed to elevate audio recording quality, making it a popular choice among musicians, podcasters, and audio engineers. Known for its affordability and robust performance, the DMP3 offers features that cater to both entry-level users and professional audiophiles.

At the core of the DMP3 are its two high-quality preamps, which utilize discrete transistor technology to deliver an impressive dynamic range and low distortion. This results in clear, high-fidelity recordings that preserve the nuances of any sound source. The preamps boast a gain range of up to 60 dB, providing ample amplification for various microphones, including dynamic, condenser, and ribbon types. The unit supports phantom power, making it compatible with condenser microphones that require additional voltage for operation.

One of the standout characteristics of the M-Audio DMP3 is its exceptional headroom and low noise floor, which allows for capturing clean audio without interference or hiss. The preamps also include a useful -20 dB pad switch, which can be engaged to avoid clipping when recording loud sound sources, such as drums or amplified instruments. This feature ensures versatility in various recording scenarios, from studio setups to live performances.

The DMP3 features balanced XLR output, which minimizes signal degradation and noise interference over long cable runs. This output is particularly useful when connecting to other audio interfaces, mixers, or recording devices. Moreover, the unit is housed in a rugged metal chassis, ensuring durability and portability for those who might be on the go.

The design of the M-Audio DMP3 is user-friendly, with clearly labeled knobs for gain adjustment and easy-to-read indicators for signal presence and clipping. This intuitive layout means users can quickly set up their equipment without getting overwhelmed by complex controls.

In summary, the M-Audio DMP3 combines high-performance microphone preamping with essential features, making it an excellent choice for musicians and audio professionals looking to enhance their recording quality. Its robust design, versatile compatibility, and high-quality output make it a reliable tool for capturing sound with clarity and precision. Whether in a studio or on the road, the DMP3 stands as an essential component in any audio setup.
