New Man



For Hi Fi enthusiasts, nothing says becoming a new man, more than following in John Atkinson's footsteps, and making your own mobile recording.

For us, there is no microphone more suitable for this, than Neumann. We've had our share of Earthworks, and keep a Blue Yeti Pro, which is rather Neumann-esque, handy, but nothing says Neumann, other than the real thing.

The Stereophile Test CD 2 was the bait that got us to leave the magazine stand, and sign up as a subscriber to Stereophile. For only a few dollars more than the cost of the CD, one could have a full year's subscription to the magazine, along with the CD itself.




Here's a DPA 4041, similar to the B&K 4006 used in the recording.


We followed in rapt attention to Stereophile's Concert recording notes, featuring a local musician of little interest, Robert Silverman. John Atkinson used a pair of B&K 4006 Omnidirectional microphones along with the EAR 824M microphone pre-amplifier. What's notable about the B&K 4006 is that it's available as a 130V phantom powered unit, and as such, has some solid specification.

Also of interest is the Rens Heijinis microphone preamplifier.



B&K Microphones, like Neumann, are legendary, and are presently available under the DPA (Danish Pro Audio) brand. The DPA HMA 5000 DPA Microphone Pre-Amplifier is the unit to look for, should you select this high-end (130V) recording option.

Those monitoring on headphones may choose the ... Headphone Pre-amplifier which also has a high-voltage specification.

Perhaps the easiest microphone to use on the Neumann road is the KU100 bin-aural head. Going in on the cheap, we've had the Sennheiser MKE 2002 substitute, rather than the original KU81, but there is no substituting the sound of a genuine Neumann "Kunstkoff" head, KU100, KU81, or the KU80, which started it to begin.

It does a respectable 20 Hz to 20 kHz recording, allowing 145 dB SPL with pre-attenuation. This will match both the human ear and the latest in DA converter capability.

Those with a penchant for fun may instead choose the Neuman USM 69i condenser, which allows for X/Y and M/S recording.



It's a monster of a microphone which will satisfy those looking to experiment safely out of the limits of their super-tweeter.

Sink in a few more $, and you'll be taking a look at the Sanken CO-100K.

For a recording device may we recommend humbly the Korg MR-2000 and the DSDx2 specification for your masters.
