Sound Pure's Take

With so many microphone builders poring over technical drawings and schematics of 50-year-old Neumann and AKG condenser designs, David Josephson is constantly pushing the envelope rather than regurgitating. The C617 is a prime example of this effort. A far cry from the KM84s, C28s, or KM54s of yesteryear, the C617 delivers a clarity, depth, and level of definition that feels supernatural, yet more musical than other hyper-clean SDC options. Most notable to the C617 is the mic body, designed to be powered by 48V phantom, but capable of applying a mind-blowing 200V to the capsule.

The DRS-8 developed by Phoenix Audio UK is an 8 channel, Neve influenced, preamp designed with Class A discrete technology with both the professional and home studio artists in mind. Modeled after Phoenix's other famous preamps, the DRS-1 and DRS-2, the DRS8 uses a transformer less, Class A, discrete mic input which gives you a "valve-like" sound. The Phoenix Audio DRS-8 is extremely versatile complimenting an array of instruments including acoustic guitars, electric guitar, percussion instruments, vocals, horns, and keyboards. The cost-per-channel is also unbeatable for a preamp of this quality. Please contact our experts, here at SoundPure, with any questions 919.682.5552 or 888-528-9703.

The D2H VN from Collings is a beautiful square-shouldered 14-fret dreadnaught, the most popular steel-string acoustic guitar body shape in the world. Although its bass response makes the dreadnought ideal for vocal accompaniment, Collings versions are also often employed by bluegrass flatpickers who must compete with inherently louder instruments such as banjos and fiddles. The wide range of woods and neck sizes offered allow dreadnought fans to find a Collings model ideally suited to their playing style and tonal preference. The D2H brings new tonal clarity, depth and warmth that is usually associated with these large body guitars. If you have any questions regarding this guitar or any others from Collings contact us here at Sound Pure. 919.682.5552 or 888.528.9703

This powerhouse guitar offers warmth and richness, pronounced in the lower-mids, yet still produces a lot of volume and an overall balanced warm tone. The Madagascar Rosewood is about as close as you can get to the old Brazilian Rosewood. The XP, or extra presence option, is a slightly enlarged sound hole.

From Josephson Engineering


The Josephson C617 is the second generation of our high voltage metal diaphragm omnidirectional microphone, suitable for the most critical sound recording and measurement applications. It operates from standard P48 phantom power yet provides full 200 volt polarize potential for a lab grade standard "half inch" microphone capsule. The C617SET is supplied with a Microtech Gefell MK221 capsule. The dynamic range is dependent on the inherent noise of the microphone capsule and the limits of P48 phantom power. The Josephson cascode FET front end circuitry introduced in the C606 is further refined in the C617, combined with our traditional balanced bipolar class-A symmetrical output stage.

For music recording, the Josephson balanced symmetrical circuitry together with a sub- micron thickness metal diaphragm capsule translate to the purest, most open sound possible. Pickup of sound pressure alone results in no proximity effect, very low sensitivity to wind noise, and phase accuracy that cannot be obtained with directional microphones. Spot-miking applications or overall stereo pickups using spaced pairs take on a new level of detail and precision not possible with other types. The small capsule size results in a nearly perfect omnidirectional pattern for accurate pickup of the whole acoustic environment.
