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 or to any standard amplified speaker output via the supplied speaker cable. The transmitter

can also be connected to other audio outputs, such as headphone outputs, by using an appropriate

adapter. The transmitter can be adjusted to the audio level provided by the audio source via a

transmitter volume control.

Q: Does the transmitter connect to the amplified speaker output of my surround sound

receiver?

A: Yes, the transmitter can be connected directly to an amplified speaker output.

Q: Is the technology used similar to Bluetooth or MP3?

A: Even though both our transmitter / amplifier and Bluetooth / MP3 use digital audio, there is a

fundamental difference between Bluetooth and how audio is transmitted by our transmitter.

Bluetooth is only able to transmit audio data at very low data rates reliably (typically up to 200 kbps).

Therefore, only compressed audio can be transmitted via Bluetooth. A commonly used technique to

compress audio data is MP3. Our transmitter, however, does not compress the audio and transmits

the full bit rate. As a result, the audio quality is not degraded such as with MP3. Also, the audio

latency (audio delay) of MP3 compressed audio is fairly high and thus not suitable for television or

surround sound applications. Since our transmitter does not compress the audio and since only a

minimum of data buffering is used, the audio delay is minimal.

Q: What is Forward Error Correction and why is it used by the transmitter / amplifier ?

A: Occasionally, there may be some data which is corrupted during transmission. This may be the

case when there is interference, such as other transmitters, electrical sparks or if you move around

and the signal is temporarily lost. Forward Error Correction as it is used by the transmitter / receiver

can in most cases repair the data which is received to guarantee 100% correct data reception and

therefore 100% correct audio reception.

This technology is in part responsible for the high robustness of the transmission. With analog audio

transmitters you may have noticed 'clicks' or 'pops' during sparks which often occur when switching

on appliances.

Q: Can this transmitter / amplifier be used to transmit surround sound to rear speakers ?

A: Yes. In this case the transmitter needs to be connected to the two rear speaker channels of your

surround-sound decoder. You can either use a line-level audio output if available or an amplified

speaker ouput. Both outputs can be connected directly to the transmitter.
