A mobile studio for vocal recordings

The SC 425 USB is a complete and easy-to-use package aimed at budding audio engineers, home-studio enthusiasts, and podcasters alike. A simple USB connection and your recording voice are all you will require to get started! It also features a useful headphone output for zero-latency monitoring. The SC 425 has an even more affordable little brother, the SC 420 USB. Unlike the latter, however, the 425 is fitted with two dedicated controls for gain and output volume as well as a red LED to indicate its operating status. A foam pop filter is also included to guard against plosives, as are a suspended shock mount (to minimise vibrations and handling noises) and a round table stand. The whole package is very attractively priced, providing a professional-grade audio recording solution for the many.

Proximity effect for an enhanced sound

Large-diaphragm microphones such as the SC 425 USB are valued for their high sensitivity and accurate rendition. In addition, their proximity effect is more pronounced than that of small-capsule mics – in other words, the closer you are to the microphone when speaking or singing, the warmer your voice will become. The same effect will apply to other sound sources such as guitars and pianos. Large-diaphragm microphones are extremely versatile, and every studio should have at least one. Podcasters will also appreciate the richness and “radiophonic” quality of their sound.

Plug & play

The SC 425 USB eliminates the need for an audio interface, preamp, and all associated cables – which is ideal if you’re impatient to get started, or on the road a lot. The mic's dedicated potentiometers allow you to subtly adjust the input gain and the headphone output volume. Thanks to its plug & play functionality, the microphone works out of the box with both Windows and Mac operating systems without needing to install any drivers. The integrated headphone output allows you to directly monitor the input signal without any latency. The SC 425 USB is primarily aimed at podcasters and singers who want to record in a home-studio environment, which is why the package includes a pop filter, a table stand, and a shock mount.

About the t.bone

Since 1994, the t.bone has been one of Thomann’s in-house brands, and its name can be found on devices such as headphones, wireless systems, in-ear equipment, and various microphones and matching accessories. “the t.bone” products are made exclusively by renowned companies who also manufacture products for other well-known brands. This provides a clear advantage: Brand-quality products at very reasonable prices. And word gets around: One in seven Thomann customers has already bought at least one product from the t.bone.

A saviour in many situations

The frequency response of the SC 425 USB features a slight bump at around 10 kHz, adding a subtle yet recognizable shine to the voice that is often found in professional recordings. In addition, the SC 425 USB has a cardioid polar pattern, which effectively attenuates unwanted sounds and interference from its back and sides. Room and ambient noises are thus kept to a minimum, even if the home studio does not have the proper acoustic treatment.

Perfect microphone.
Anonymous 24.11.2022
The microphone spec. was ideal for my remote group jam sessions on Skype and Zoom. The microphone on my laptop just couldn't cope with the music side of things. The SC 425 comes in a hard case with pre-formed foam padding, so great for safe transporting. It takes just a few minutes to put together, the 2m cable plugs into the computer and requires no driver installation. It's so simple. Ordering was very straight forward, and it was shipped within a day. Text messages kept me informed of the delivery progress, as has happened with all Thomann products that I have ordered in the past. Very efficient and friendly staff. Thanks for the great service.

top notch - einfach klasse Mikro für Sprache
Fender335 09.02.2022
Einfach ein klasse Mikro.
Der Fuß, der Ständer und die Spinne sind aus Eisen und das Mikro steht wie eine Eins bzw. hängt perfekt in seiner Halterung. Der Schwanenhals mit dem Filter ist auch gut.

Sound: hier kommt die Qualität - kein Rauschen, wirklich KEIN Rauschen (ich muss es groß schreiben). Ich nutze das Mikro zum Einsprechen von Lehrvideos, Software-Doku und ähnliches und meine Stimme kommt einfach gut damit rüber. Ein Schmeichler und meine Kollegen fragen mich, wo ich so Sprechen gelernt habe - das Mikro trägt seinen Teil dazu bei.

Negativ: der Mute-Button ist unbrauchbar. Wie jemand hier schon schrieb, das Auslösen von 'mute' erzeugt einen lauten Plopp. Hätte ich Live-Zuhörer, würden die das voll auf die Ohren kriegen, in Videos nutze ich das nicht oder könnte das rausschneiden. Aber für den Live-Einsatz oder beim Podcast ist das einfach Mist. Da würde das 420er reichen mit der gleichen Technik.

Aber sei's drum, ich würde diese Mikro jederzeit wieder kaufen, die Soundqualität und die Standhaftigkeit sind Spitzenklasse.

Très bon micro de qualité
Lionel. N 22.04.2022
Après avoir testé plusieurs micro différents, j'ai utilisé le SC 425 USB.
- Super son audible et clair
- Design, boîte et packaging au top
- Une lumière bleue est émise de celui-ci, avec un bouton mute composé d'un témoin rouge. C'est vraiment sympa !

Je recommande ce site Thomann ainsi que ce micro.
