Music Without Cable Clutter? - The Latest Generation Of Wireless Audio Transmitter Devices
A large number of wireless audio transmitter products have emerged over the years. They claim to eliminate the cables to your audio equipment. We will take a look at recent products to see if they can deliver on their promise to eliminate the cable clutter and we’ll investigate how changing technology has influenced performance of these products.
The first form of wireless audio transmission was in the form of AM and FM radio stations. FM radio is still popular until today even though some modern technologies such as satellite radio and digital radio formats such as HD radio and DAB radio have begun to replace traditional FM radio. Today's wireless consumer devices such as wireless speaker kits, baby monitors, Bluetooth audio transmitters and wireless microphones eliminate the cord.
Many homes which are not wired for audio are ideal for using wireless audio to distribute music throughout the home. The technologies used today all have pros and cons as we will examine.
One of the most traditional technologies is FM broadcasting. Audio is transmitted via a radio-frequency signal which is modulated (changed in frequency) with an audio signal. This technology is called frequency modulation or FM. It is fairly simple to implement. Thus FM transmitters are very cost-effective. In addition, FM transmission offers high range. As a consequence, most of today’s 900 MHz wireless headphones utilize FM transmission. However, FM has some major drawbacks.
The FM signal will pick up hiss. Therefore there will be noticeable background noise. The amount of static will depend on the location of the transmitter and radio. FM radio waves are often reflected by walls and obstacles. This will cause several components to cancel each other out as a result causing a varying signal quality in different locations. This phenomenon is known as multipath fading. One method to cope with this problem is utilizing two antennae instead of one. Products utilizing this technique are called diversity receivers. FM radios will easily pick up interference from other consumer devices which is another problem.
Bluetooth based audio transmitters have gained popularity lately. Bluetooth is a popular wireless protocol which was designed primarily as an interface between computer peripheral products. Bluetooth will convert he audio into a digital format. This data is then broadcast via the Bluetooth wireless protocol. While offering high robustness against wireless interference, Bluetooth has several pitfalls in regard to audio transmission since it was never designed with the purpose of transmitting audio. The first disadvantage is the limited range which typically would be 30 ft or less. The second drawback is the fact that Bluetooth does not have sufficient space to transmit CD-quality audio and for that reason the audio is compressed first. Due to the compression, the audio quality will be degraded in comparison to the original. Bluetooth will cause a delay or latency to the audio signal which is a problem for surround sound and video applications because the wireless loudspeakers will be out of sync with the remaining speakers and video.
Satellite radio and digital terrestrial radio technologies offer high range but use extensive audio compression leading to degradation of the audio signal and have an audio delay of several seconds.
The technology used in Amphony's wireless audio transmitters sends audio in a digital format without audio compression. The signal will keep the original quality by eliminating audio compression. The audio latency of this technology is less than 1 ms. As a result it can be used for real-time applications such as wireless speaker kits in home theater setups.
By using error correction, this technology can cope with interference from competing wireless products which is key in today’s noisy environment. Rather than utilizing the crowded 900 MHz and 2.4 GHz frequency bands, Amphony products operate at 5.8 GHz and thus offer high reliability. In contrast to Bluetooth, any number of wireless receivers can operate from a single wireless audio transmitter which is a consideration when sending audio to several rooms within a house.
What chord do i need to hook up a condenser mic to an audio interface.?
I just recently bought a Creative E-mu usb 404 audio interface and a perception 120 condenser mic. What cable do i need to buy to hook both of them up to it. The audio interface has 2 Mic/hi-z/line inputs. 2 S/pdif, a midi in and out and a speaker output. any help?
You need a 3 pin XLR Balanced Microphone cable (cord). And you'll need to turn the Phantom Power on on the interface. Any decent pro-audio shop should be able to sell you one. Go for a good quality one - don't buy cheap.
SitRep: Battlefield 3 (Game Informer)
Battlefield 3 launched to critical praise from game journalists, but as with
most online-based games, once the public jumped into the fray several issues
surfaced. EA's servers had trouble accommodating the heavy demand, and many
people decried the new web-based Battlelog service. Now that the game's been
patched a couple times, we checked in to see how the game is performing.
**Triumphs**
* **Big Battles:** Ask PC players what Battlefield 3's best feature is, and
most will respond with "64-player conquest." Given how long DICE made the fans
go without large-scale skirmishes (the 2005 release Battlefield 2 was the last
modern military game in the series that accommodated this many people), this
response wasn't a surprise. This is the way the game is meant to be played.
* **Controls:** As an 11-year veteran of the genre, DICE knows controls.
Everything from the smallest handgun to the largest missile launcher feels
great and responds well. The ground vehicles are easy to use, and the air
support options are justifiably more difficult to control but not impossible
to learn if you put in the time.
* **Audio:** I don't think a shooter ...
