5.8 GHz DIGITAL Wireless Audio Transmitter /
Amplifier, Model 1550
Q:What is the difference between the Amphony 5.8 GHz Digital Wireless Audio Transmitter / Amplifier and current 900 MHz or 2.4 GHz analog audio transmitters ?
A:There are 3 major differences:
1)Digital transmission: The first difference is how the audio signal travels from the transmitter to the receiver. Almost all of the current wireless systems on the market use a method called FM (Frequency modulation) which is very similar to the operation of your FM radio. The major drawback ist that this type of modulation is ‘analog’ which is the reason for the poor performance of analog transmitters.
If you listen carefully to a CD over an analog wireless audio transmitter / amplifier, you will notice significant noise/static, low signal dynamics and low channel separation. Also, the signal quality will vary when you move around the room between the transmitter and receiver (the noise will increase locally and also the further the receiver is moved away from the transmitter).
The transmitter uses something which is called ‚digital' modulation. The same way music is recorded on a CD using 1's and 0's, it is transmitted as 1's and 0's to the headphones. The result of this technology is that there is no audio quality degradation during transmission, i.e. you will hear the exact same audio quality as you would if the equipment was connected by a cord.
Because of this digital technology, our transmitter / amplifier is very suitable for
2)Transmitter frequency: The second difference is the higher transmit frequency of 5.8 GHz. This frequency avoids possible interference from other appliances working either in the 900 MHz or 2.4 GHz range, such as cordless telephones or wireless LANs.
3)
Q: Can the amplifier connect to loudspeakers ?
A:Yes, the amplifiers each provide a speaker output and connect directly to regular loudspeakers.
