Gen 2 is Here
We’re excited to introduce the VANGUARD AUDIO LABS V4 gen2! 
we have upgraded key components to audiophile-grade parts, including US-made low-noise resistors. These upgrades have netted us a lower signal-to-noise ratio (even though we already had a superb reputation for low noise mics), and vastly improved sound staging.  We undertook a ground-up redesign of every mechanical component to improve the fit and finish of the final product, so not only are they world-class performers, but they look damn good while they’re doing it!
We designed V4 with certain characteristics of classic FET 
microphones in mind, while also utilizing modern technology & design
 to meet the demands of today’s recording professionals. Our ultra-thin 
3µm edge-terminated capsule diaphragms are extraordinarily sensitive, 
ensuring that every nuance and detail of the performance is faithfully 
captured.
We heard from a number of Vanguard V44S users that they loved the 
clean and full character of the V44S so much as an alternative to their 
V13 and V1 microphones, they wanted a small “mono” version of the V44S 
for travel purposes. The signal and power paths of the V4 is identical 
to a single channel of the V44S, but because we had space for an extra 
PCB and switch, we couldn’t resist adding a simple pad/rolloff combo 
switch to the rear, as well as spacing the power conversion circuit as 
far as possible from the signal path.
After hundreds of hours of listening with world-class engineers in 
environments ranging from fully-equipped major studios to bootstrapped 
home setups, we can confidently say that this microphone will vastly 
exceed the performance of other microphones in its price range, and 
rival the performance of microphones costing several times more.
