A Glimpse At Some Of The Hottest Wireless Audio Toys
Latest-generation wireless audio products such as iPods, iPhones and wireless surround sound products promise to cut the cord while delivering crystal-clear audio. I will examine whether or not these products keep their claim to deliver perfect-quality audio. Furthermore, I will examine the underlying technologies.
Products can be categorized into devices with built-in and those with optional wireless ability. Streaming audio devices will often have a plug-in slot for adding a wireless LAN card. Newest generation iPods and mobile phones already come with built-in WiFi and Bluetooth support.
The Bluetooth protocol is a fairly low-cost option. However, its limitations have an impact on high-quality audio applications and are often ignored.
1) Limited range
Bluetooth devices normally only have a 30-foot range which restricts Bluetooth to single-room applications.
2) Small data rate - audio compression
Bluetooth offers a maximum reliable data rate of around 1 Mbps only. This rate is not high enough to broadcast uncompressed CD-quality audio. Consequently Bluetooth wireless devices utilize audio compression. This is less critical though for compressed audio such as MP3 audio but excludes Bluetooth from use in high-quality audio applications.
3) Signal latency
The signal transmitted via Bluetooth will bear a slight delay of no less than 10 ms. This is mostly due to the audio compression. While being uncritical for MP3 players, this delay may be a problem for video and other real-time applications.
4) No support of multiple headphones
Bluetooth can't stream to multiple headphones at the same time. This might be a dilemma in cases where a number of people want to listen to the same Bluetooth transmitter.
Uncompressed audio streaming is supported by WiFi. WiFi is a very widespread protocol. Yet, WiFi also has pitfalls in terms of simultaneous transmission to several receivers. As a result of the fairly high power consumption it is hardly ever used in wireless headphones though. WiFi is convenient for streaming audio from a PC however since almost all PCs have WiFi access.
Wireless speakers and wireless amplifier products for home theater speakers typically employ their own proprietary protocol. Entry-level wireless headphones and speakers generally still use FM transmission which offers low cost but is prone to noise and audio distortion.
More recent wireless audio protocols are based on digital transmission. This eliminates audio degradation. Some protocols also incorporate error correction to cope with interference from other wireless devices.
Latest-generation wireless amplifiers utilize uncompressed audio transmission. Latest protocols also permit streaming to an unlimited number of receivers. This allows whole-house audio distribution.
Some of these protocols support low-latency audio transmission which ensures that the audio of all speakers will be in sync in a multi-channel application. Wireless audio transmitter products typically work at 2.4 GHz or sometimes in the less crowded 5.8 GHz frequency band such as Amphony's wireless audio devices.
These wireless amplifiers also differ in regard to amplifier output power, standby power consumption and audio quality. A high-quality audio amplifier is critical for optimum sound quality. Digital amplifiers generally offer a power efficiency of no less than 80% and standby power consumption of less than 5 Watts which keeps them cool during operation and helps save energy. However, some Class-D amps have fairly high audio distortion. Audiophile wireless amplifiers offer an audio distortion of 0.05% or less.
what can i do this with an rca ending with a audio plug?
what is it for?
it looks like this but without red rca

whats it for?
It goes from a PC or headphone output to an audio RCA input or from an RCA stereo output to a PC-like audio input
Wicked Audio's Solus headphones let you listen like a DJ at the flick of a switch (Engadget)
For what it's worth, Wicked Audio has a habit of producing egregiously loud
headphones -- looks-wise, that is. Hence our surprise, when we glanced at its
latest red and black offering in our Gmail inbox. The Solus, "Latin for be
yourself" as we're told, doesn't look like much more than a basic set of cans,
but the inline volume control on its braided cable serves a unique function
for all you budding record-spinners out there. With a flick of this puppy's
"DJ switch," you'll be able to rattle both of your ears in stereo, or have an
easier time listening with just one of 'em when it comes time to crossfade
into your next track. No word on specs (not that we'd expect any), but letting
go of a Benjamin will snag you the Solus when it officially releases at CES.
_Wicked._
**Update:** A representative for the company has sent over some specs for
cans:
* 40mm "high performance" drivers
* 106 dB SPL
* 20-20,000 Hz
* 32 ohms
* 4 ft cord
* gold plated plug
