The 4 channel Earthworks 1024 Microphone Preamp is based on the philosophy that extended frequency response and faster cleaner time domain performance, will yield more life-like results. The unit is housed in a 1U rackmount chassis.

Earthworks was formed by David Blackmer, the inventor of dbx, to realize his vision of upgrading the entire audio chain to new standards of sonic realism. To that end, the unit is currently the quietest preamp available, particularly evident when high gain is used in recording classical music.

Any change that an electric signal undergoes as a result of passing through electronic components is referred to as distortion - clipping heavy-metal guitar signals being an extreme example - but is not limited to clipping alone. For the audio purist, the goal is to have as little distortion as possible affecting the audio signal.

The 1024 with its Zero Distortion Technology (ZDT) delivers immeasurable amounts of all forms of distortion, with a frequency response that is flat and wideband. Further, the preamp provides the recording engineer with the ability to accurately capture sound exactly as it happens in any sonic environment. This still allows for making sonic coloration and textural choices at a later stage, while retaining the original, life-like recording.

    Comments about Earthworks 1024 Microphone Preamp:

    The resolution and detail that this preamp presents is simply stunning. I have used and A/B tested many other 'clean' preamps such as the Grace m801, Millennia HD-3D, and the Benchmark MPA1. The Earthworks rises above all of these in terms of soundstage, dynamics and clarity. On A/B comparison with other mic pres the 1024 presents a much wider and deeper image. The recorded source takes on a holographic characteristic rather than just a clean 'flat' one that the others present. This is a special piece and it achieves a sonic level above all others that I've heard. I have put many sources through this unit including keyboards and two channel stereo tracks. No matter what I pumped through this thing it improved the sound 100%. In fact, even using it live as the first stage before going into my Presonus StudioLive 24, the sound was drop-dead amazing compared to the Xmax pres. I was in the market for the finest 'price-no-object' mic preamp and I found it. What a fitting legacy left to us by the great sonic renegade David Blackmer.
