Professional Headphones 15 % Off Sale at Sonic Electronix

Professional Headphones Promotion

If you are looking for an upgrade in the field of home, DJ, or studio Professional Headphones now is the time to act. For a special limited time only Sonic Electronix will be offering a 15% discount on all of our Professional Headphones. As the holiday season comes around the corner now is the perfect time to purchase those high quality headphones you have always wanted. With manufacturers like Audio Technica, Grado, Sennheiser, Kicker and many more you are sure to find exactly what you want and need.

Professional Home Headphones

The want for high-quality sound reproduction is what sets the true audio listener apart from your average every day listener. Headphones like the SR60i and SR80i from Grado offer a fuller sound reproduction that is almost never seen in your standard pair of headphones. Here you will get cleaner, crisper and more accurate highs, mids, and lows. Kicker’s HP541 headphones also provide that higher-quality that makes listening to music a whole new experience.

Professional DJ Headphones

With professional DJ style headphones not only is sound quality important but aside from that they must feature some sort of swivel of the ear-cups and extreme flexibility. Pioneer’s HDJ-500K, and HDJ-1000 offer unique folding housing and joint movement that allow for flexibility during performance which allow for easier use when mixing. The same goes for the Shure SRH750DJ and SRH550DJ headphones. These headphones excel in low and mid frequency reproduction which is essential to a good DJ. A DJ is only as good as his equipment, and these DJ style headphones will allow for true artistic presentation.

Professional Studio Headphones

Studio monitoring headphones are a complete different ballgame in the professional headphone category. These headphones will pick up a very wide range of frequencies which is needed for proper monitoring and mixing. Audio Technica’s ATH-M50, Sony’s MDR-V600, and Sennheiser HD 280 Pro headphones all offer a very dynamic sound reproduction and are able to reproduce frequencies that are not always heard but play a significant role in the overall sound quality and production. Studio monitoring and mixing professional have a great sense of hearing but even they need a reliable pair of professional studio headphones to get the job done as accurate as possible.


Demystifying Microphones

Samson Gtrack

An Introduction to TransductionShure SM57

Microphones are how we convert sound into audio, or more specifically electrical impulses that represent sound waves using an analogues wave form where the various peaks and troughs of a sound wave are represented in both frequency and amplitude by an electrical signal.   This process, as well as any process in which one form of energy is converted into another form of energy, is called transduction. In fact this is the exact opposite of how loud speakers work.

Different Kinds of Microphones

The key component of a microphone is the transducer which is commonly referred to as the capsule.   In music production there are two basic microphone designs.  These types are based on the type of capsule they use.

Dynamic MicrophonesDynamic Microphone

Dynamic or moving coil microphones such as the Shure SM57 (pictured above) use electromagnetic induction to recreate the electrical signal interpreted as audio.   Sound Waves from your voice or guitar amp come contact with a mylar diaphragm which is attached to a coil suspended over, on, or around a magnet.    The intended frequency response and polar pattern is the direct result of the size and type of magnet being used being ferrite or neodymium and the orientation of the coil.

Condenser MicrophonesCondenser Microphone

Condenser Microphones condenser mics such as the Audio Technica AT2020 (pictured below) operate a little differently.   Sound waves still contact a diaphragm in the same fashion but instead of being directly attached to a moving coil the diaphragm serves as one of two metallic plates suspended with an electrical charge between them.  The diaphragm plate is free to move in direct correlation with the sound waves that contact it while  the fixed back plate  remains stationary in relation to the diaphragm. Audio Technica AT2020 The electrical charge between the two plates exhibits a variable level of capacitance.  As the plates move closer and further apart with the sound waves, a bias signal directly modulated by the capacitance is interpreted as audio.  Because the transducer as well as the bias signal requires an electrical charge to operate, an external power supply is needed and is most commonly found in the form of Phantom Power.  Phantom Power is +48V of DC power typically supplied by a microphone preamp, although sometimes condenser microphones are powered by internal batteries as well as AC power supplies.

Less physical energy is needed to move the diaphragm of a condenser microphone therefore they can be much more sensitive. For this very reason dynamic microphones are used more frequently in live sound reinforcement as open air monitors tend to cause condenser microphones to feedback. Dynamic microphones are favored on drums as their simpler circuitry results in a faster more articulated response as well as high SPL tolerances.
