Products can be categorized into merchandise with engineered-in and those with optional wireless capability. Streaming audio products will typically have a plug-in slot for adding a wireless LAN card. Latest generation iPods and cell phones already return with built-in WiFi and Bluetooth support.
Bluetooth is a fairly low-price solution however has some drawbacks that are often overlooked.
1) Limited vary
Bluetooth devices usually only have a thirty-foot range which limits Bluetooth to single-room applications.
2) Low knowledge rate - audio compression
Bluetooth reliably supports knowledge transmission rates of around one Mbps only that isn't enough for uncompressed CD-quality audio. So Bluetooth applies audio compression. This is often less important though for compressed audio like MP3 audio however excludes Bluetooth from use in high-quality audio applications.
3) Audio latency
Because of audio compression, Bluetooth can introduce an indication delay of at least 10 ms which will cause the audio to be slightly out of sync in case of video and real-time applications. This is again less of a drawback for MP3 players.
4) No multiple headphone support
Bluetooth does not support any number of headphones which might be a downside if you have a bigger range of individuals who wish to listen to headphones from one transmitter device.
WiFi is another widely used wireless protocol that's also appropriate for audio streaming. WiFi does support uncompressed audio however can have issues transmitting to a large range of wireless receivers simultaneously. Thanks to the fairly high power consumption it's rarely utilized in wireless headphones though. WiFi is convenient for streaming audio from a PC however since nearly all PCs have WiFi access.
Wireless speakers and wireless amplifier products for home theater speakers sometimes use their own proprietary protocol. Entry-level wireless headphones and speakers usually still use FM transmission that offers low price however is at risk of noise and audio distortion.
Additional advanced wireless protocols are based on digital formats which eliminate audio degradation and incorporate advanced options such as error correction to address interference from competing wireless devices.
Advanced wireless amplifier devices support uncompressed digital audio streaming to preserve the first audio quality. A number of these protocols enable streaming to a vast variety of wireless amplifiers that is convenient for whole-house audio distribution.
The audio latency ranges from below one ms to up to 20 ms. A little latency is vital for wireless surround sound applications. These wireless audio transmitters typically work at 2.four GHz. There also are some product which work at 5.8 GHz. Product that operate at 5.8 GHz have less competition from alternative wireless devices than those using the crowded 2.four GHz frequency band.
These wireless amplifiers also differ in terms of amplifier output power, standby power consumption and audio quality. A high-quality audio amplifier is important for optimum sound quality. Digital amplifiers usually provide an influence potency of a minimum of eighty% and standby power consumption of less than five Watts which keeps them cool throughout operation and helps save energy. However, some Category-D amps have fairly high audio distortion. Audiophile wireless amplifiers offer an audio distortion of 0.05% or less.
