The new series of wireless transmitter devices promise unlimited streaming music in the entire home. This article will explore the various technologies and products to see how they can work for whole house audio and to learn what to watch out for.
The use of infrared audio wireless devices is limited to applications that require line-of-sight. Infrared wireless audio devices can only work within one room, because they send the signal as an infrared beam that cannot penetrate walls. This technology is commonly found in wireless speakers kits.
These devices transmit music via radio waves. The radio waves are able to pass right through the walls. This signal can be broadcast by FM transmission, or digital transmission. It is a cheap transmission but it can be susceptible to distortions, interference and static youtube mp3 converter.
Amphony products, which are digital audio transmitters that transmit wirelessly, follow a protocol. Audio is first transformed into digital data and then broadcast. Using this method, the audio quality can be guaranteed to remain intact. Some transmitters, like Bluetooth transmitters for example, use some type of audio compression that will cause the audio quality to be degraded. Uncompressed audio transmissions will provide the best fidelity.
Because wireless LAN wasn’t designed to stream audio in real time, it will introduce some delay or latency. WLAN receivers usually require that a separate LAN-card be purchased and plugged in to each receiver.
These products transmit audio through the mains power and have a long range. These products have issues in houses with multiple mains circuits because they can’t cross-over into another circuit. They also include a delay in order to prevent transmission errors when there are power spikes or surges. However, this can make them unsuitable for applications that require the wireless speaker audio to match other speakers and video.
For the optimal wireless audio system, here are some suggestions: Look for systems that allow you to run multiple receivers wirelessly from one transmitter. The ideal system should support an infinite number of receivers. You won’t be required to buy additional transmitters as you add more receivers. Some devices include error correction to help protect against dropped audio in the event of a strong wireless disturbance. To ensure that audio quality will be preserved, choose a digital radio frequency audio transmitter. You should ensure that the audio delay for a real-time video or other application is less than 10ms.
You should choose a receiver that offers all audio inputs, such as RCA or speaker. speaker inputs, RCA inputs etc. Buy a system that allows you to buy additional receivers in the future. It is important to confirm you will be able to get receivers that work with all your applications. Receiver types include receivers with amplifiers, receivers at line level for active or passive speakers. You should choose a receiver that allows you to control the volume. The transmitter can be connected to various equipments with different signals levels. If not, the audio might be clipped at the converter stage in the transmitter and the dynamic range will not be utilized.
To ensure maximum power efficiency, check that the amplifiers are digital. The receiver will remain cool when operating. As well, ensure that your amplifier produces low levels of audio distortion. For good sound, this is crucial. It is important to ensure that your amplified speaker receiver has the ability to drive the speakers you prefer. Also, it should be small enough and mountable easily for easy installation. The 5.8GHz frequency is usually less congested than the 900 MHz and 2.4GHz bands, so products using this band are less susceptible to wireless interference.
