The A-Designs Audio 500 microphone preamp series is comprised of five different 500 series-compatible mic/line pres. We have meticulously voiced each one with a specific sonic functionality in mind. The A-Designs EM Blue 500-Series Preamp Module is equipped with a nickel custom-wound output transformer for accentuated highs. The EM-Blue is the brightest sounding of the EM Series.
It produces an airier, more top-end oriented tone than its EM-Series brothers and sisters. Many aspects of recording can be counter-intuitive; and, in many cases, you would want to pair opposites.
For example, when used with a dark-sounding microphone or an alto vocalist, the brighter EM-Blue can open the sound up. This pre is also useful for providing a crisp ‘crack’ when recording a snare drum. If you use the direct input, you just might fall in love with how an electric guitar sounds going thru its nickel transformers. The EM-Blue has a -20dB pad that enables you to get down and dirty with an electric guitar – just switch in the pad and crank the gain for a slight growl.
The main features of the A-Designs EM Blue 500-Series Preamp Module include:
- Nickel wound output transformer
- Accentuated high tones and harmoincs
- Perfect addition to any recording chain
These units are physically compatible with any API or VPR Alliance mounting device. Also it meets the precise power rating requirements necessary to function perfectly from the moment you plug them in.
The electronics behind the A-Designs 500-Series Preamps
We want to help you select the proper module for you, and then it can be beneficial with a basic understanding of the electronic components.
Knowledge on how the different components and their inherent physical qualities affect sound is helpful when deciding on the proper module for the right application.
Our transformers occupy a key position in the circuit design due to their ability to affect timbral quality. Apart from the utilitarian task of electronic isolation for noise-free operation, the alloys used for the transformer’s winding, along with the number of windings, will impart a distinct sonic quality. For instance, a nickel-wound transformers provides a more transparent sound with an airy high end. While steel can impart a thick “Neve-like” midrange or low-end “API growl”.
To give each preamp in the A-Designs Audio EM-Series its own unique character, each has custom-wound transformers using proprietary A-Designs alloys. All have been painstakingly tested to produce the perfect sound for the right application. This means that the decades of collective experience between A-Designs Audio and highly respected audio professionals have taken the guesswork out of finding the right preamp for the job. Think of each of the EM series preamps as the master of a specific domain in the frequency spectrum.
For example, the EM- Silver is stunning on the lower frequencies thanks to its steel-wound transformer, making it a perfect choice for bass or kick drum. While the EM-Blue’s nickel transformer provides the clarity needed to bring out the “crack” on snare drums, or to gently coax the highs from ribbon mics…
