The latest wireless audio transmitter devices allow unlimited music streaming throughout the house. The following will be a look at different technologies and devices to discover how well they work with whole-house audio systems and what you should look for.
Devices that transmit audio via infrared light are limited to direct-line-of-sight. This technology can only operate within one single room as the infrared signal cannot pass through walls. The technology is used in wireless speaker products youtube mp3 converter.
Radio-frequency wireless music devices send the music signals via radiowaves. They can pass easily through walls. It can either be done using digital or FM transmission. While FM is a low-cost option, it’s prone to noise and distortion.
Amphony and other digital transmitters of wireless audio, like Amphony devices, use the protocol. Prior to broadcasting the audio, it is converted first into digital data. This ensures that audio quality is preserved. Some transmitters, including Bluetooth transmitters will use a form of compression to reduce audio. Highest fidelity is obtained by using transmitters which do not compress the audio.
Although Wireless LAN is a great option for PC streaming, the wireless LAN technology was never designed with real-time audio in mind. WLAN receivers normally require the purchase of a separate network card that must be plugged into each receiver.
They offer a wide range and transmit the audio over the electricity mains. The main problem is that they cannot cross from one circuit to another in a home with individual circuits. The delay is designed to avoid transmission errors due to power surges.
Picking the right wireless audio is not easy. Here are a few recommendations: Choose a system with multiple wireless receivers that you can control from a transmitter. It is ideal to be able to support as many receivers as you want. This way, you do not need to invest in extra transmitters once you begin adding receivers into different rooms. Some devices are equipped with some sort of error-correction, which helps to prevent drops in cases of wireless interference. You can ensure audio quality by using a digital RF transmitter. When using real-time applications such as video, you should make sure that your audio delays are less than 10 ms.
Pick a transceiver that includes all the audio inputs needed, e.g. speaker inputs, RCA inputs etc. Consider a wireless setup that will allow you to purchase separate receivers at a later date. Verify that there are receivers available for each application. You can choose between amplified receivers or receivers that are line-level. The transmitter should be able to adjust the volume. It will allow you to use the transmitter with any equipment, regardless of the signal level. If you don’t, then the audio will be clipped or not utilized fully.
Make sure the amplified system has digital amplifiers for high-power efficiency. This helps keep the device cool while in operation. Also, check that the audio distortion is low. The sound quality will be better if you have a good amplifier. The amplified transmitter should have the capability to drive speakers that are rated at the Ohm value you want. It also needs to be compact, easy-to-mount and small for an installation that is simple. It is more likely that products operating in the lower 5.8 GHz spectrum will have fewer wireless interference issues than those using 900 MHz, 2.4 GHz or other frequencies.
