2.4 GHz DIGITAL Wireless Audio Transmitter /
Receiver, Model 1000
Q: What is the difference between the Amphony 2.4 GHz Digital Wireless Audio Transmitter /
Receiver and current 900 MHz or 2.4 GHz analog audio transmitters ?
A:
The main 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 / receiver, 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).
Our transmitter / receiver 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 receiver. 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 / receiver is very suitable for high-quality audio,
such as music coming from a CD, DVD, digital satellite receiver etc.
Q: Can the receiver connect to loudspeakers ?
A:
The receiver does not contain a power amplifier and therefore cannot be connected directly to
loudspeakers. The receiver can connect to active speakers, amplifiers and other audio equipment
that have a standard high-impedance analog audio input. For direct connection to loudspeakers, we
recommend our Model 1520 and Model 1550 transmitter / amplifiers.
Q: How does the transmitter connect to my audio equipment?
A:
The transmitter connects to any standard audio line output via the supplied stereo RCA audio
cable. In cases where no line output (RCA audio out) is available, the transmitter can also connect
to other audio outputs via appropriate adapters which are not supplied with the product. By using a
Y adapter which has either a 3.5 mm or a 6.3 mm audio plug on one side and 2 RCA plugs on the
other side, the transmitter can be connected to headphone outputs. Please note that most
headphone outputs can be adjusted in volume. It is imporant that any adjustable outputs be set
such to the level which yields the highest volume at the headphones without clipping (distortion).
