Generation of picture signals
Generation of digital picture signals from analog picture signals to display associated screen on left rear display.
Generation of IR signals
Generation of digital IR audio signals from analog audio signals for transmission to headphones (cordless) connected via the IR interface.
Output of audio signals
Output of audio signals via following options:
- Analog:
- Headphones connected by cable to the integrated headphone socket (cable-connected)
- IR:
- Headphones connected via the IR interface (cordless)
The volume of the audio signals can only be adjusted via the remote control for headphones connected by cable to the integrated headphone socket. For headphones (cordless) connected via the IR interface, the volume of the audio signals is adjusted via the volume control integrated in the IR headphones.
