Suggestions For Selecting The Perfect Wireless Audio Transmitter Product For Whole-House Audio Streaming
The latest series of wireless audio transmitter products claims streaming of music throughout the house without limits. We will have a look at numerous products and technologies to find out in how far these devices are practical for whole-house audio applications and what to look out for when buying a wireless system.
If your home is not wired for audio then you face quite a challenge when you want to get your music from your living room to your bed room. Often the audio source cannot be moved. Running speaker wires between rooms will be costly and consequently a lot of people are searching for alternatives. The following technologies are utilized by devices solving this problem: infrared, RF, Wireless Lan and powerline.
Infrared is restricted to line of sight since the audio signal is sent as lightwaves and consequently devices using this technology, such as infrared wireless surround sound products, are limited to a single room.
RF wireless products will send the signal as RF waves. These waves can without difficulty go through walls. RF wireless audio products either make use of FM transmission or digital audio transmission. FM transmitters are the cheapest alternative. They offer decent range but the music signal is prone to audio distortion and noise and is extremely susceptible to interference from other wireless transmitters.
Products which employ digital wireless audio transmission utilize a digital protocol. Such devices include transmitters from Amphony. In this protocol, prior to transmission the audio signal is converted to digital data. This conversion and transmission in the digital domain will ensure that the original audio quality is preserved. On the other hand, this is only the case of the data is sent uncompressed. Some wireless audio transmitters will apply some type of audio compression. Such products include Bluetooth audio transmitters. Audio compression will degrade the quality of the audio to some extent.
Wireless LAN (WLAN) products are practical when streaming from a PC but will add some amount of latency or delay to the signal since wireless LAN was not originally designed for real-time audio streaming. WLAN receivers frequently do not have built-in network access. As a result, such devices often require purchasing separate LAN cards. These cards are then plugged into every receiver.
Powerline devices utilize the power mains as a medium to broadcast the audio. These products normally offer excellent range. On the other hand, they face problems if there are several separate mains circuits in the house. In this situation the signal will have trouble crossing between these circuits. Powerline products have another challenge in the form of power surges and spikes which can cause transmission errors. To avoid audio dropouts, these products will normally have an audio latency of several seconds as a safeguard.
Now we’ll give you some tips for shopping for a wireless system: Pick a system that supports multiple wireless receivers if you plan to stream audio to a number of rooms so that you don’t have to purchase a separate transmitter for each receiver. Some products have some form of error correction built in which will help guard against dropouts in case of strong wireless interference. Digital RF audio transmitters will be able to maintain the original audio quality. If you have time-critical applications where sync of the audio is important then you should get a transmitter with a low audio latency. An audio latency of less than 10 ms would be appropriate for most scenarios.
Pick a transmitter that has all the audio inputs you require, such as speaker inputs, line-level RCA inputs etc. Get a wireless system where you can purchase separate receivers later on. You should confirm that you can get receivers for all the different applications you have. Such receivers may include amplified receivers for passive speakers or line-level receivers for active speakers. Choose a transmitter that can adjust the audio volume of the input stage. This will give you the flexibility to connect the transmitter to any kind of equipment with different signal levels. Otherwise the audio may get clipped inside the transmitter converter stage or the dynamic range is not fully utilized.
Ensure that the system provides amplified receivers with a digital amplifier to guarantee high power efficiency. This will help keep the receiver cool during operation. Also, make sure the amplifier offers low audio distortion. This is important for good sound quality. Choose a system that offers receivers that can drive speakers with the desired Ohm rating. Make sure the receivers have a small form factor and are easily mountable. This will help during the set up. Products which function in the 5.8 GHz frequency band will have less trouble with wireless interference than products using the crowded 900 MHz or 2.4 GHz frequency band.
