Audio Authority 1177A Digital Audio Switch
Electronic switcher for coaxial and optical digital audio sources
Audio Authority 1177A Digital Audio Switch / AutoSelector
Following in the footsteps of the highly respected model 1177, the Audio Authority 1177A brings an all-metal cabinet for improved shielding and appearance. But this is more than an 1177 in a metal box - the all-new design also offers new circuit board architecture for superior performance.
This high-performance digital audio switch can expand the digital audio capacity of any audio system. It automatically selects the active audio input and it can convert optical and coaxial signals automatically and transparently so you can connect any combination of optical TOSLink and coaxial digital audio sources.
The 1177A digital audio switcher outputs both optical and coaxial signals simultaneously, converting seamlessly between the two formats. For example, you can have a satellite receiver connected to input one via TOSLink optical cable and a DVD player connected to input two via coaxial cable. No matter which input is active, the switcher will always output both optical and coaxial formats from that source. Supports all Dolby Digital, DTS, and PCM formats.
Like most Audio Authority products, the 1177A Digital Audio Switch comes with a one year limited warranty from the manufacturer.

The front panel has multi-color LEDs to indicate "auto" mode and input selection status, as well as a push-button switch for manual source selection.
This picture shows the back panel. If you zoom in, you can see four optical TOSLink digital audio inputs at the upper right, with a corresponding coaxial digital input below each optical input. The output connectors are on the left side. The power input connector is located between the input and the output connectors.
Shown here is the product box and the included contents. Starting at the upper right, moving in a clockwise direction, you can see the box, an installation instruction sheet, some adhesive labels, a universal power supply, and the 1177A unit itself.
Here is a closer look at the included universal power supply. As you can see, this will work with just about any power system. The plug itself is intended for the USA, so if you are in a different country, you will need a passive adapter.
