As I have started to accumulate a number of audio tech reviews, you know that because you have read them isn't that right, searching out the experiences I can offer up I almost forgot one really important product. In quest for a decent selection of microphones I would bite the hand off any poor soul wielding a fuzzy dictaphone, I had great joy trading cash for a dozen dynamic microphones out of a church, but out of the blue I was offered a classic AKG C451 for nothing! A friend (haggard live pro moving into the chip shop career) cleared out his stuff and I appeared to be the beneficiary of an awesome tool!
So basically in summary the C451 is a pencil condenser microphone, the small diaphragm in the C1 cardioid capsule is renowned for its excellent ability to capture sources with high transients (a drum cymbal for instance). I like a greedy kid at the sweet shop put it to work as soon as possible, what a revelation! It was like a cloud concealing high frequencies were dispersed and a clear spectrum began to emerge, drums had never sounded better. On acoustic instrument the richness of the wooden bodies was transposed into pure ear candy.
But alas for every high the flaws started to creep in, I began to notice an irritating humming from the microphone once connected that intensified immeasurably at the touch of skin. This problem was solved sometimes by slightly unscrewing the cap, a solution but none the less disappointing to have to be used.
Overall it is a fabulous microphone, the humming noise most likely has occurred over the years after heavy use (its actual age is still unclear) so yes if you find a chance to buy one, and I know its mind boggling the different variations on the same thing, BUY ONE!
This little c451B is a great microphone! This is a condensor microphone manufactured by audio well knowns AKG, who also make microphones such as the C1000s and the D112!
These are sold separately or also now sold as a stereo pair for when recording ensembles for example! I personally use them in stereo pairs as overhead microphones when recording drums and they sound great!
The frequency range of the microphone is exactly the rough range of human hearing which is 20HZ to 20KHz, so it can pick up all of the frequencies we hear to give it a varied range in what it can be used for!
The microphone, just like most other condensor microphones, requires phantom power of around 48v to power it but this is standard in applications now and youll probably find that your sound card for example will offer this power to the microphone when turned on!
It features quite a focused pickup pattern which maeks it very reliable from picking up certain sounds within an ensemble for example, however as i mentioned before they can now also be purchased in a stereo pair in which two of the microphones can be placed together at 45 degrees to each other to give a much wider pickup pattern while still maintaining the quality that they offer!
For performances in which other unwanted frequencies in the low end may occur (low rumble off mic stand when recording vocals for example) the microphone has an in built bass roll of switch to 75 or 100 Hz as depicted by the user.
This microphone is a very reasonably priced one in its field and the sound quality is fantastic, these have many uses whether it be live or in the studio and are a very versatile bit of kit to have onboard!
Worth a try and you ont be unhappy with the results!
The AKG C451b is a great quality, small diaphragm condensor microphone. It is phantom powered and has the popular used cardioid polar pattern.
This little, but popular mike is idea for the most sensitive situations. With a good wide frequency range 20Hz to 20,000Hz, exactly what is meant to be a humans hearing range.
The frequency response of the microphone is fairly flat, apart from a slight increase from around the 10KHz to the 15KHz mark. This however is a bonus, as it emphersizes the 'airy' sound that the microphone is famous for creating.
There are filters and pads built into the microphone. It can be set to 0dB, -10dB and even -20dB for some extreme cases. The filters included are a bypass of nil, 75Hz and 150Hz, once again making this mike even more adjustable for any situation.
With such a wide frequency and good lift for air in the 15KHz range, this microphone is perfect for almost all acoustic situations. Whether its acoustic guitar to pick up the shine and ring of the chords, or a piano to pick up every last note from the bass to the top. This microphone suits all. It is perfect for drum kit hi-hats and overheads with such a high frequency response. With a 75Hz and a 150hz pad it also can filter out any unwanted drum noise from things such as the tom-toms and the kick drum.
This microphone however, has been used in other situations by many famous producers. This includes using, taped to an SM57 to the snare drum. With the -10dB or -20dB pad on, it can pick up the brightness of the snare, and when mixed with the recording of the SM57 it can give an unbelievable sound. This is a technique I have used myself and is fantastic to experiment with.
This microphone comes at around the £200 mark, although I managed to get mine at £179 when the prices were slightly cheaper. This is very cheap compared to many mikes used professional in the thousands of pounds range. You can also purchase this microphone with a matched pair, making it perfect for stereo miking, whether its XY or coincedental. The pair will also make perfect use for two drum overheads.
Although the beginning producer or engineer may see this microphone as a little to steep in price compared to cheaper models avaliable, it is definately a purchase that can last a lifetime!
Why not try it yourself!
The C 451 B is an excellent tool for accurately capturing signals rich in transients such as drums, instruments with a percussive sound, acoustic guitar, or for overhead miking.
