SEM-02 Specification, Deeper Explanation

For those of you who have SEM-01 microphones and have upgraded to SEM-02, you know the difference, right? Physically, they are very different. Or those who are still curious can read our previous posts here.

But can you tell the difference between the specifications?

Well, here we will discuss more of the specifications of the SEM-02, which on paper is superior to its predecessor, the SEM-01.

1.Ultra-high sensitivity
The SEM-02 uses an ultra-high sensitivity electret condenser microphone (-33 dB@ 1 kHz), so soft sounds can be captured clearly without the need to raise the input gain too much. Automatically, the accumulated noise from the connected devices (audio interface, mixer, cable, etc.) will be minimized so that the noise floor of SEM-02 is much smaller than that of SEM-01.

2.Higher maximum SPL up to 116 dB
With a maximum SPL of up to 116 dB, it makes the SEM-02 more capable for miking instruments with high SPL such as snare drums, timpani, cymbals, kick drums, etc. without worrying about peaks.

3.Higher dynamic range up to 100 dB!
Thanks to its high signal-to-noise ratio (78 dB) and coupled with a higher SPL input reception capability (116 dB), the SEM-02 has a wide dynamic range (acoustic) of up to 100 dB!*. It makes soft sound well captured clearly and when we play a fortissimo tone (very loud) it will not peak/distort. This also applies to speech/dialogue, soft voices and shouts will be captured well too.

*The dynamic range calculation is obtained from the acoustic overload point (116 dB) minus EIN (Equivalent Input Noise). The EIN of SEM-02 is 16 dB which is obtained from 1 pascal (94 dB) minus SNR (78 dB).
