Pros: This is a good entry level microphone.
ELECTROVOICE COBALT 4 PROFESSIONAL MICROPHONE
If you have ever gone shopping for an entry level microphone, I am sure that you know that there is no shortage of contenders. But when there are so many models to choose from, the task can be a bit daunting. I hope that by reading this review, you will be able to more easily narrow down your possible choices. With this goal in mind, I shall today be reviewing the ElectroVoice Cobalt 4 Professional Microphone. The ElectroVoice Cobalt 4 lists for $149.00, but it can easily be found for a discounted price of around $49.99. As of this writing, there is a large national musical instrument chain store that is running a buy one get one free deal on this microphone for the price of $49.99. That is a real steal in my opinion.
The ElectroVoice Cobalt 4 is a Dynamic, Cardioid, microphone. Unlike a condenser microphone that requires phantom power in order for it to work correctly, a dynamic microphone, like the ElectroVoice Cobalt 4, requires no external power source for it to operate correctly. It is a microphone with a cardioid polar pattern, which means that it is most sensitive to picking sounds that it is being pointed directly at, and it rejects sounds or is less sensitive to picking up sounds that originate from the back or sides of the microphone. Obviously, this is a bit plus in a live performance situation, as one does not want to be amplifying sounds that are coming from sources other than the desired source that is being miced. A microphone with a cardioid pickup pattern is also a big plus in a recording situation, as this type of microphone is less likely to pick up extraneous sounds coming from musical instruments or other sound sources, and as such, the recorded track is cleaner. This might not seem all that important to an inexperienced person who might be reading this, but trust me, it is a very big plus. Imagine you have recorded an acoustic guitar track in a home studio, and because a home studio may not have proper sound proofing, you may have some sound leakage from the group’s bass player or from the drummer’s kick drum. Then imagine trying to boost some of the acoustic guitar’s low end frequencies during the final mix to make it sound richer or fuller. The result would be a nightmare, as doing so would also boost the volume of the bass guitar or bass drum, and the result would be an indistinct muddy mess. That is one of the many reasons why a microphone with a cardioid pickup pattern is so helpful when making home recordings, and obviously for professional recordings as well.
The ElectroVoice Cobalt 4 is a microphone that was specifically designed to record or amplify the sound of a number of types of musical instruments, such as electric or acoustic guitar, brass instruments, tom toms, snare drum, and hihat. The frequency response is fairly wide, and it is from 50 Hz. to 18,000 Hz. This would not be a good choice to consider for recording a bass guitar, upright bass, or a kick drum, as the low end frequencies and their undertones can be below 50 Hz., and as such, they will not be picked up. I would also not consider this microphone as an overhead for drums, as the crispness of the cymbals and their high overtones would also not be picked up as well as they could. Finally, although the ElectroVoice Cobalt 4 is capable of amplifying or recording the human voice, it would not be my first choice here either, as there are microphones that are specifically tailored to bring out a vocalist’s voice.
Well who is the ElectroVoice Cobalt 4 suited for? It is suited to best meet the needs of a person who needs an entry level microphone that will make acceptable recordings for a home studio situation, or for amplifying certain musical instruments in a live setting, such as a snare drum, saxophone, or electric guitar cabinet. The ElectroVoice Cobalt 4 is a good microphone for all of these above mentioned situations. It is a very good microphone for the price, and delivers a lot more quality than many other microphones in this price range. However, do not confuse it’s capabilities with a truly good dynamic microphone, such as an ElectroVoice RE20.
