Automatic adaptive 4-input multi-source component video, analog audio, and digital audio (coax and optical) switch. The Model 1154A is an enhanced version of the Model 1154, with improved shielding, input circuitry and signal sensor adjustment features.

Adaptive Signal Sensing AutoSelector� component video and audio switch.

Integrate multiple component video sources! If you own a receiver and/or TV with limited inputs, you can use the 1154 to add multiple A/V sources. It uses proprietary Adaptive Signal Sensing� technology to switch between two to four sources automatically.

The high bandwidth circuitry accepts Y Pb Pr component video, stereo analog audio, and digital audio in both optical and coaxial formats, and switches all audio and video signals simultaneously when a new source becomes active. Digital audio signals are converted automatically to the desired format. Up to four sources may be connected to one receiver/video display system through the 1154A.

The 1154A uses multiple criteria to decide when to switch sources, and adapts to users' activity patterns, customizing its switching behavior over time. Another feature allows the user to assign a priority level to each source. A typical example could involve both a satellite receiver and a DVD player connected to the Model 1154A. If the power on the satellite receiver is left on, its signal will be detected constantly by the 1154A. But by assigning the DVD player a higher priority, the 1154A would automatically select the DVD whenever its signal is detected, even though there is also signal present from the satellite receiver. A manual select button is provided to override the 1154A's automatic selection. Multi-color front panel LEDs indicate source availability.
