STO-2          Add to cart


The STO-2 is a pressure transducer. So are your ears. No Coincidence.
We started out looking for a natural sounding mic and this is what we came up with.

Sold in matched pairs, (two ears right?) the STO-2’s are perfect for capturing instruments that need no flattery.
With a matched pair, stereo is no problem – Jecklin disk or spaced pair – it will sound like you are standing there.


Transducer Type 0.25″ Electret condenser pressure
Polar Pattern Omni-Directional
Output Level 5.25 (mV/Pa)
Frequency Response 20 Hz – 20 kHz (+0/-2 db)
Equivalent Noise (A-weighted) 28 dB
Maximum SPL 145 dB (with 48V powering)
Output Impedance 20Ω (load ≥ 1kΩ )
Power Requirements P48 phantom power (~6 mA)
Weight 3.6 oz (100 g)

The graph looks a bit bumpy until you check out the scale. Mics are matched to within 1/2 dB difference in sensitivity.
Then every set of mics goes through a final listening test

Check out our applications section for more ideas.

Made in the USA from solid aluminum, the mics are built to withstand the rigors of the studio or the road.
At only 5″ long and 1″ around they are easy to position and fit in standard mic clips.
