Audio Authority 1154A
4x1 Component Video and Audio AutoSelector Switch
Audio Authority 4x1 Component Video and Audio AutoSelector Switch
The front panel has multi-color LEDs for power and input selection status, as well as a push-button switch for manual source selection. The recessed areas below the source LEDs may be used to label your sources. Labels are included.
The Audio Authority 1154A adaptive signal-sensing electronic switcher provides high-performance automatic switching for HDTV Component Video, as well as digital and analog audio sources!
The 1154A is an updated version of Audio Authority's well-regarded model 1154. By comparison, the 1154A has improved EMI shielding, for even lower noise and more reliable switching. In addition, input selection criteria is now user adjustable via DIP switches, adding even greater flexibility. It's a great update to what was already a class-leading product!
This innovative switcher expands the input capacity of any receiver, pre-amp, processor, or HDTV, providing four sets of automatically switched inputs for Y/Pb/Pr video, stereo analog audio, as well as digital audio. It automatically selects the active input, and also includes a switch for manual override.
As a bonus, the device also provides seamless conversion of the digital audio medium so optical or coaxial digital sources may be used interchangeably and transparently.
Audio Authority's exclusive Adaptive Signal Sensing™ technology uses multiple criteria to decide when to switch sources, and adapts to your activity patterns, customizing its switching behavior over time.
The 1154A has undergone a minor internal change, replacing obsolete TOSLink jacks with a newer parts, so the official designation is now 1154A1. The high-bandwidth circuitry ensures high-performance switching for your high-bandwidth Y/Pb/Pr HDTV format component video. The 1154A has plenty of bandwidth to handle all consumer video formats, including (but not limited to) 480i, 480p, 720p, 1080i and 1080p. It also switches stereo analog audio, and digital audio in both optical and coaxial formats. When a new source becomes active, it simultaneously switches the audio and video signals to that input. Multi-color front panel LEDs indicate source availability. The physical size of the device is 8.5" x 5.5" x 3.25".
As an added bonus, the 1154A works equally well with both composite video and S-Video.
Like most Audio Authority products, the 1154A comes with a one year limited warranty from the manufacturer.
Included items
The 1154A comes complete with the device itself, a power supply, rubber feet, mounting screws, adhesive labels for the inputs, and documentation, as shown in the picture to the right.

Overview
Consumers who own a receiver and/or TV with limited inputs can use the 1154A to add multiple A/V sources. Its exclusive Adaptive Signal SensingTM technology uses multiple criteria to decide when to switch sources, and adapts to users’ activity patterns, customizing its switching behavior over time. The high bandwidth circuitry accepts HDTV component video (YPbPr), 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. A manual select button is provided to override the 1154A’s automatic selection. Multi-color front panel LEDs indicate source availability.
