5.8 GHz DIGITAL Wireless Headphones, Model 2500

Q: What is the difference between the Amphony 5.8 GHz Digital Wireless headphones and

current 900 MHz wireless headphones ?

A: The main difference is how the audio signal travels from the transmitter to your headphones.

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 900 MHz analog

headphones.

If you listen carefully to a CD over 900 MHz analog wireless headphones, 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 (the noise will increase locally and also the further you move away from

the transmitter).

Our headphones use 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 with corded headphones.

Because of this digital technology, these headphones are very suitable for high-quality audio, such

as music coming from a CD, DVD, digital satellite receiver etc.

Q: What is the difference between the Amphony 5.8 GHz Digital Wireless headphones and

Amphony 2.4 GHz Digital Wireless headphones ?

A: Amphony 5.8 GHz Digital Wireless headphones operate at a higher transmitter frequency than

the 2.4 GHz Wireless headphones and are recommended for situations where other 2.4 GHz

appliances, such as cordless telephones or wireless networks, may cause interference.

Q: Can these digital headphones also be used for my analog television or receiver ?

A: Yes. In addition to two digital audio interfaces, the transmitter also has an analog audio interface

which connects to the standard line output of your analog television or receiver. The analog audio is

converted to a digital signal inside the transmitter and then transmitted digitally to your headphones.

Please note that even though there is no audio degradation during transmission to your head-

phones, you will hear noise if the analog input signal is already noisy. This is often the case for

analog audio sources.
