Sontronics STC-20 Pack: cardioid polar pattern

The Sontronics STC-20 Pack has a cardioid polar pattern just like the famous Rode NT-USB . As its name suggests, the directivity of this type of microphone is in the shape of a heart. It captures sound sources facing the microphone and rejects those located behind it. Sounds from the sides are also attenuated.

The STC-20 is therefore designed for recording vocals and instruments in the studio or at home. This is the ideal microphone if your home studio is not acoustically treated. Indeed, this microphone displays a directivity targeted towards the front . Therefore, it does not reproduce the approximate acoustics of your recording studio.

If you want to capture sounds all around the room, you should opt for an omnidirectional microphone like the Blue Yeti pro studio for example.

Also note that there are versatile microphones that can play the role of both an omnidirectional microphone and that of a cardioid microphone. This is particularly the case with Blue Snowball. To change the sensitivity of the microphone, simply press a button on its back. It's practical, isn't it?

The Sontronics STC-20 Pack and its practical accessories

Let's return for a moment to the accessories supplied with the STC-20 microphone. This is indeed an offer that is very rarely found on the market. The Sontronics brand spoils us with all the gadgets delivered in the same box as the microphone.

By opting for the Sontronics STC-20 Pack, you will no longer need to purchase other additional accessories to optimize the quality of your recordings .

Let's see together what the first accessory could bring us: the shock absorber . This is a spider type model. This device being very stable, it serves to eliminate noise when you manipulate the microphone . Furthermore, this support equipped with elastics also helps eliminate foot vibrations .

The pack also contains an anti-pop filter, your best ally during your vocal recording sessions. Placed between the mouth and the microphone, this custom-made device has the role of banishing parasitic noise . Among other things, it helps you obtain better recording quality when you pronounce the letters “B”, “P” or even “T”.

And the icing on the cake: the zipped protective pouch . This is useful when you are on the move. In addition, it is also very practical for keeping the microphone safe when not in use.

In addition, discover our test and review of the Austrian Audio OC18 microphone . It is a bidirectional microphone which has a fixed polar pattern and a single diaphragm. This guide presents the technical performance, sound quality, and technical characteristics of this condenser microphone.

Sontronics STC-20 Pack: a model specialized in multiple applications

From vocals to acoustic guitar to piano and many other acoustic instruments, the Sontronics STC-20 Pack can accommodate a wide range of sources . This is why it is called an all-in-one microphone.

This versatile mic can also be used to record a guitar amp . However, be careful not to place the microphone close to the amp so as not to obtain a too bright sound. As it is a condenser microphone , it is therefore very sensitive on the treble.

It would therefore be wiser to opt for dynamic microphones or ribbon microphones if you are looking for perfect sound for your electric guitar.

The STC-20 is also very popular with teachers giving online courses. Thanks to the pop filter, the microphone produces clear, noise-free sound. Enough to be easily understood by students.

Focus on the sound quality of the Sontronics STC-20 Pack

Now let's talk about sound quality, a criterion not to be taken lightly when purchasing a microphone.

First of all, note that this model is among the least expensive in the Sontronics range. Although its price is accessible to everyone, it is not deprived of quality, far from it. Indeed, the STC-20 benefits from the same care as the STC-2, a high-end model from the British brand.

The STC-20's frequency response ranges from 20 Hz to 20 kHz . It offers an excellent signal/noise ratio thanks in particular to its large membrane. It also has the particularity of effectively rejecting background noise . It provides clear sound with plenty of detail.

Our opinion on the Sontronics STC-20 Pack

For use in the studio or at home, I recommend this Sontronics microphone. This model from the British brand offers good quality recordings with a minimum investment.

The accessories supplied with the condenser microphone can significantly improve the quality of recordings. It should be noted that it is more cost-effective to purchase the Sontronics STC-20 Pack rather than purchasing a microphone, pop filter and shock mount separately.

Furthermore, you will no longer need to worry about accessory compatibility by opting for the STC-20 Pack. In fact, these are all accessories designed specifically for the microphone.

The STC-20 Pack really adapts to multiple applications, as the manufacturer specifies in its recommendations. Whether for singing, podcasting or acoustic instruments, the quality is always there. And this is an advantage that the STC-20 shares with the other high-end model from the same brand, namely the STC-2.

Given its performance and versatility, this microphone represents a good investment if you want to set up your home studio. What's more, the price-quality ratio is very interesting.
