Not disturbing others while watching TV at night is likely still the main use of wireless headphones. Wireless headphones in particular are enjoying a high popularity by not being tied to a cord. Traditional wireless headphones could however never match corded headphones in terms of sound quality and realiability. The main culprit would be the wireless transmission itself which would be prone to noise and interference. New advances in wireless technology promise to remedy these drawbacks. We will review two models of wireless headphones which utilize the latest transmission technology to find out how these products compare to traditional corded headphones.

The two review models are the Sennheiser RS180 and the Amphony Model 2500. Both models use the latest digital audio transmission technology. This means that prior to transmission of the audio signal by the transmitter, the signal is first converted to a digital data signal which then gets transmitted. Inside the digital wireless headphones, the signal is then converted back to an audio signal. Using this digital transmission, none of the two models showed any hissing or distortion that we are used to from previous wireless models. Both headphones claim to transmit true CD quality audio.

Looking at the headphones, we immediately noticed that the Sennheiser headphones are designed as open headphones which means that sound from the transducers can easily penetrate to the outside while the Amphony headphones are closed. Choosing between an open and closed design is a matter of preference and there is no way to state that any particular design is better than the other. A closed model will tend to reduce the sound level heard by others which is useful when listening at loud volume. At the same time a closed design will tend to attenuate exterior noise more. Both models are equipped with soft velours ear cushions and fit snugly.

When not in use, the RS180 headphones can be suspended from the transmitter which acts as a support base. The RS180 transmitter offers a regular analog audio input but no digital audio input. The Model 2500 transmitter offers one analog audio input, one coaxial digital audio input and one optical digital audio input. The digital inputs are useful when connecting the transmitter to a plasma TV for example which normally don’t have analog audio outputs anymore. The Model 2500 transmitter will automatically switch to the correct audio input by detecting which audio input has a valid signal.

Comparing both models in terms of sound quality, the RS180 has a light sort of quality and excels at the midrange but is low on the bass. As such the RS180 is most suitable for listening to vocal racks and light music. The Model 2500 has a more pronounced bass response, but in no way aggressive and is well balanced. The wireless transmission no longer has the problems of older headphones and the sound quality of both models rivals corded headphones. The only limitation is the fact that wireless headphones are powered by batteries and thus will never be able to blast the same volume as corded headphones connected to a good headphone amp. However, both models were able to achieve reasonably loud levels, the Model 2500 more so than the RS180.

The RS180 transmits it’s signal at 2.4 GHz. Up to four headphones can operate simultaneously per transmitter. The Model 2500 transmits at 5.8 GHz and supports an unlimited number of headphones. The operating range of the RS180 is specified by Sennheiser at 300 ft. During our indoor testing we were able to get a clean signal up to around 100 ft with both models which should be sufficient for most users. The Model 2500 transmitter comes with an extension port though that allows connection of secondary transmitters for cases where you really need to have reception all over the house.

Battery life is 15 hours per charge for the RS180 and 30 hours for the Model 2500. The RS180 wireless headphones sell for around $300 and the Model 2500 for around $200.

I need to give a shout out to the homey Drake. I was in N. Y filming this past week and spent a large amount of time in the auto listening to the radio. Hot 97 was playing 'Over' once an hour, as well as 'Say Something,' his collusion with Timberland. What I was most impressed with nonetheless was being in the center of Bedford Stuyvesant in Brooklyn and hearing his single blasting out of apartment windows and each passing automobile with oversized edges. To have a legion of 13 year old female fans and simultaneously have your music being played in the hood displays an incredible range that is a recipe for lasting success. But why is it that so few people in the States mention that Drake is from Canada? Even better why is it that Canada only welcomed this home grown product after he began to blow up south of the border?

Drake isn't shy about repping his home and local land, but the sad truth is that before he signed with money money, a lot of Torontonians were hating on Jimmy from Degrassi's new hobby. He ain't real, he's's from Forrest Hill, he is's soft, are two phrases I heard. Generally, and excluding Vancouver which supports the shit out of their local talent, Canadians only seem prepared to embrace their own when our neighbours from the south give their mark of approval. Maybe its our self-depreciating humour and way of looking at the world that reaches to hating on home grown talent and products. Or maybe its the indisputable fact that we import the bulk of our culture from the States, I don't truly have a solution. My best guess would be a mix of the above, joined with the incontrovertible fact that our population numbers only 30 million, compared with three hundred million, which makes it tricky for any person to get big in Canadian hip hop industry as literally the entire country would need to be listening to them. What I know for sure is this country breeds lots of accomplished folks in the entertainment industry, and when those people become 'successful' they move to, or at the very least work in, America.

E-40 sold 100,000 tapes out of the trunk of his vehicle in the Bay Area alone. That would NEVER happen in Canada. Birdman claims to have accumulated 50 million dollars when he was twenty-one years old from travelling across Louisiana and neighboring states distributing monthly mixtapes in local record stores. Whether or not that could be a evil boost and he only made 1,000,000, that would NEVER happen in Canada. Down south, indie hip hop artists are supported by their community, a community that's pleased with its local product and thus helps that artist gain a bigger audience. In Canada, for some unknown reason we wait for authorization this is in fact 'good' or 'real' before we embrace our own. Drake has reached an amount of rap superstardom that no Canadian before him has acheived. Maybe this will be an important point where we take pride in, and embrace our talent** so helping them to gain a wider audience rather than impedeing them with our shortage of support. But perhaps not, because after all , I did not write this post six or eight months back before Best I Ever Had got huge, and it took me going down to Manhattan and hearing it everywhere to validate his greatness in my mind. Generally Canadian.

DJ Equipment Speakers

Loudspeakers are, of course, an extremely critical portion of any DJ's set up, hence you have to very carefully give some thought to your choices. And you will never find any kind of shortage of possibilities. Internet vendors stock just about all the leading makes and varieties, and you'll typically learn quite a bit by simply searching the on-line descriptions. Needless to say, if you have any associates who are DJs you will get a lot of tips from them.

First off, there are two types of dj equipment speakers: active and passive. Active speakers have got amplifiers built-in, which means that all you do is deliver a signal from your mixer to each speaker. Obviously, you need to adjust the speakers prior to your event, and there exists the matter of getting electrical power to each speaker meaning extra wires run to wherever you locate your speakers. But many DJs have a preference for this system as well as simplicity it provides.

Passive speakers don't have any built in amplifier, therefore you will need to have either an external amp or a powered mixer that will feed your speakers.

I have a preference for passive speakers connected to an external amplifier. But this is a topic of personal inclination.

DJ Equipment Mixers

DJ Equipment Mixers are at the center of any DJ's set up. For the brand-new DJ the options could be somewhat bewildering, but they need not be. A mixer is simply that - a component that lets you combine two or more inputs into a single output that generally feeds your amplifier and then your speakers. It really is a lot more that merely a "switcher" that permits you to choose inputs, even though sometimes that is what it's used for. And it's more than just a volume control, even though, once again, it does that, too. However it does a good deal more.

DJ equipment mixers allow you to have all those amazing fades from one particular input to the other. Some mixers feature built-in effects so you can transform your audio in incredible ways. Most all mixers have got EQ controls which allow you to contour the sound arriving from the different channels by fine-tuning the bass, mid-range, and highs.

One other thing a mixer does for you is it allows you to utilize a pair of headphones to listen to just one channel at any given time, or to listen to the whole mix. You will discover this to be particularly useful.

The DJ doesn't have to have some huge console mixer with 24 or even more channels. Generally four channels will adequate. Stick with one of the top brands and truly learn to use your DJ equipment mixer and you will be off to a superb start.

Summary

The main thing is that your entire gear - from DJ equipment speakers to your DJ mixer to headphones and microphones all operates together properly so that you get excellent audio - and happy customers.

Mingl ing his West Indian vocal dub style with a solid grounding in traditional American R&B, 17-year old Aaron Fresh, the latest addition to the growing Teen Island roster, is storming pop and rhythm radio formats with his debut single, “Spending All My Time.” The track is New & Active this week at #52-bullet on the Top 40 Mediabase chart, over 3 million strong . Upon impact the single was added to 50 stations across the pop and rhythm radio formats.

Born in the U.S., Aaron Hinton-Marshall (aka Aaron Fresh) wanted to sing by age 7 ; at 8 when he was sent to live with his grandmother in Port-Au-Spain, the tiny capitol city of the republic of Trinidad and Tobago. At a crucial time in his development, he gained a sincere appreciation for calypso, reggae and dub , especially listening by Jamaican stars Buju Banton and Sizzla. In middle school, Aaron started entering talent shows and trying out for agencies. “Any opportunity where I could showcase my talent,” he says, “I was there.”

After graduating from Holy Names Prep School in Trinidad, Aaron returned to the States to live with his mother in Southern California. During a vocal rehearsal at a friend’s house, Aaron was overheard by a producer. The chance meeting led to an introduction to Nick Cannon, whose instant reaction was “Let’s get it started” and quickly signed the young star to his recording label, NCredible Entertainment.

“My music genuinely portrays me as a person,” Aaron says, “because I’m American but have a Caribbean background. I have no musical preference, I like everything as long as you can feel the vibe through your soul.” The young vocaliser (and occasional songwriter) has been working closely with Nick Cannon every step of the way. “He’s totally involved in everything I do … I admire the guy, and he treats me like a little brother, so that’s a good feeling.”

If you have a vinyl collection, you’ll understand  what I mean when I say that current digital media just can’t yield the same natural sound as a vinyl can. The typical vinyl sound is partly produced by  the slight imperfections in each groove. Yet, even if you are extremely cautious  about handling and storing your vinyls, time will slowly fill the grooves with dust and grease. Not only does this alter the quality of the sound you’ll be getting, it will also decrease the life of your precious record collection; something that can’t be replaced easily or cheaply!

Cleaning a vinyl compilation can eat up your time and if you do it regularly  it will eventually use up the record’s surface. Currently ultrasonic cleaning provides a cheap alternative which is not only a time-saver, but is a lot gentler to use.

Ultrasonic cleaning was initially developed about half a century ago for cleaning surgical instruments and equipment in biomedical centers. Nowadays, it is also extensively used by heavy and hi-tech manufacturing, and by hobbyists as well.

So how does ultrasonic cleaning work? To begin with, an ultrasonic cleaner is a container filled with water and often with a mild detergent as well. Attached to the vat is an ultrasonic generator which turns mains electricity to high frequency ultrasonic energy, and an ultrasonic transducer which then changes this to ultrasound. As the ultrasound travels across the liquid in the tank it causes microscopic bubbles to implode and send out tiny shockwaves; these are what do the actual cleaning.

For cleansing the grooves on vinyl records, ultrasonic cleaning gives an outstanding alternative to manual cleaning.They produce tiny bubbles and shockwaves that they will simply get right into the grooves,  gradually lifting the grime out without being abrasive to the vinyl exterior. Although this process implies words like “ultrasonic” and “shockwave” it is an enormously mild form of cleaningversus manual cleaning. Sure there are shockwaves, but they’re so minute that they won’t ruin your vinyl. 

There's a wide selection of ultrasonic cleaners on the market, varying from ones which will only accommodate limited vinyls in at a time to serious bulk cleaning machines. In this size rangelook for something that  will easily fit on a work-surface or on the garage floor. Furthermore, ultrasonic cleaners in this day and age are well within the price range of the usual vinyl collection-owner.

Remember , still, that you begin  the cleaning gently and use a mild detergent; it is adequate to use washing up liquid or even tap water. A great initial step would be to test it out with a record that you won’t miss. Once you are done with ultrasonic cleaning make sure to rinse your vinyl in clean water and let it dry out before packing it away. Totally, an ultrasonic cleaner will not only save you time but will allow you to take better care of your vinyls than you would using the usual cloth.
