The Concept
Three sources are connected to the matrix: the Laptop on HDMI input 1, the PC on HDMI input 2, and a Media
player on the analog audio input. On the output side three sink devices wait for the audio signals: an HDTV
on HDMI output 1, a Monitor with speakers on HDMI output 2, and an Audio Amplifier on the analog audio
output line. The video line of the Laptop is switched to HDTV and the PC is switched to the Monitor with
speakers. The embedding and de-embedding functions of the matrix allow the infinite variations to transmit
the analog and digital audio signals.
The following ways are available for the audio devices:
▪ When the sink device is the HDTV, the audio source can be the Laptop, the PC, and the Media Player.
▪ When the sink device is the Monitor with speakers, the audio source can be the Laptop, the PC, and the
Media player.
When the sink device is the Audio amplifier, the audio source can be the Laptop, the PC and the Media

The Concept
If there is no other source connecting to the matrix, only the Laptop, the source on HDMI input 3 will be
automatically switched to the HDMI output. If the Laptop and the PC are also connected to the matrix, the
source on the HDMI input 2 will be switched to the HDMI output. If the Blu-ray player is connected through
section.
the TPS transmitter, TPS input 1 will be switched to the HDMI output – independently of the presence of the
other video signals.
