Several Guidelines To Help Choose A Cordless Surround Sound Package The newest series of wireless surround sound transmitter devices promises streaming of music throughout the home without limits. We will have a look at various products and technologies to find out in how far these devices are useful for whole-house audio uses and what to look out for when purchasing a wireless system.
Getting audio from your living room to your bedroom can be quite a problem in particular in buildings which are not wired for audio. Products which solve this difficulty are mostly based on the following technologies: infrared wireless, RF wireless, wireless LAN or powerline.
Getting audio from your living room to your bed room can be quite a challenge especially in houses which are not wired for audio. The following technologies are used by products solving this problem: infrared, RF, wireless LAN and powerline.
Infrared products broadcast the audio as lightwaves. Light cannot go through walls. Consequently products using infrared, such as wireless surround sound kits, are restricted to a single room. RF wireless products broadcast the music as RF waves - either by using FM transmission or digital transmission - and can for that reason without difficulty transmit through walls. FM transmitters are the cheapest option. They offer decent range but the audio signal is prone to audio distortion and hiss and is very susceptible to interference from other wireless transmitters.
WLAN products are useful for broadcasting audio from a PC. However, wireless LAN was never designed for real-time audio streaming. As a consequence, products using WLAN will introduce some amount of delay to the signal. Also, some products require to buy separate wireless LAN modules that are plugged into each audio receiver.
Powerline devices use the power mains as a medium to broadcast the audio. These products usually offer excellent range. On the other hand, they face trouble if there are a number of separate mains circuits in the home. In this situation the signal will have difficulty 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.
Powerline products use the power mains to distribute audio and offer great range but run into trouble if there are individual mains circuits in the house in terms of crossing between circuits. Also, these products build in a delay of several seconds to safeguard against transmission errors during power surges and spikes which prevents their use in applications where the audio from wireless speakers has to be in sync with other non-wireless speakers or video.
Pick a transmitter that has all of the audio inputs you require, e.g. speaker inputs, RCA inputs etc. Pick a system where you can add receivers later on which offer all of the necessary outputs, e.g. amplified speaker outputs, RCA outputs etc. Pick a transmitter that can regulate the audio volume of the input stage. This will give you the flexibility to connect the transmitter to any type 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.
Select a transmitter that has all the audio inputs you need, such as speaker inputs, line-level RCA inputs etc. Get a wireless system where you can buy separate receivers later on. You should verify 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. If you go with a digital audio transmitter, choose one with an input audio level control knob to prevent the audio signal from clipping inside the transmitter audio converter. This will ensure optimum dynamic range regardless of the signal level of your equipment. For high amplifier power efficiency and greatest sound quality, verify that the amplified receiver has a built-in low-distortion digital amplifier. Make sure the receivers can drive speakers with your preferred Ohm rating. Selecting a product where the wireless receivers have a small footprint and easy mounting options will help during the installation. 5.8 GHz wireless devices typically have less trouble with interference from other wireless transmitters than devices working at 900 MHz or 2.4 GHz.
