One thread that runs quite regularly through the PC-based recording newsgroups I monitor involves mic preamps. Not, so much pertaining to "which ones sound the best?" but more often- "uh, what do they do and why do I need one?" Desktop recording these days is increasingly made up of people who have little knowledge of basic recording practices (then again, maybe it's indicative of the sites I frequent). In any case, I see an obvious need for what I would term entry-level pre-amps designed for PC-based studios. M-Audio/MidiMan is addressing this opportunity with two, relatively low-cost, 2-channel models that merit your consideration if you're looking for basic improvement of your mic signal input situation. The 'baby' of this duo is the Audio-Buddy ($100)- a really diminutive unit approximately the size of a 'Walkman' style cassette player. I would call this more of a direct- box plus. With two pairs of line/mic inputs and switch-able phantom power it meets the minimum requirements for handling various input sources. The construction quality appears pretty high. I tested it with a Shure KSM32 large diaphragm condenser microphone and spun off a few vocal takes. It provides clean, mostly uncolored output but I detected a trace of harshness in the upper-mid frequencies. It's sibling is the DMP-2; ($200) same basic configuration but about the size of a paperback book with the added features of a phase reverse switch and a low-cut filter. The DMP-2 is a definite step up in sonic quality though. The vocal takes I A/B'd with the Audio Buddy demonstrated excellent clarity across the spectrum with just a hint of extra presence or 'liveness' that was most pleasing. I compared both Midiman units to my Joe Meek VC-3 Pro-channel which while slightly pricier is nonetheless aimed at roughly the same market segment. The VC-3 is actually a pre-amp/compressor/tonal enhancer. For the test I ran the VC-3 with no compression and all 'enhancement' controls turned to nominal. Running identical vocal takes through all three units I found that the DMP- 2 scored best in my "un-tampered clarity and presence" criteria. I also found that its output was considerably higher than the VC-3.

Many of you may be wondering who Moon Professional is and why you should pay any attention to another company making mic preamps. These too were my first questions when their first product was...
