Cable Solutions is proud to present the Audio Authority 1177A-1 digital audio switch!
Successor to the venerable 1177A, the 1177A-1 is manufactured by Audio Authority, exclusively for Cable Solutions.
Equal or superior to those of the 1177A, the specs for the 1177A-1 ensure outstanding performance. Aside from the dash-one in the model number and a subtlety more luxurious finish on the case, appearance remains essentially identical.
The Audio Authority 1177A-1 Digital Audio Switch features an all-metal cabinet for optimal shielding and appearance and the new design includes 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 or coaxial digital audio sources.
The 1177A-1 digital audio switcher simultaneously outputs both optical and coaxial signals, seamlessly converting between the two formats. As an example, you can have a satellite receiver connected to input one via TOSLink optical cable and a CD player connected to input two via coaxial cable. The switcher monitors all inputs, waiting for a state change. So in the example above, if the satellite receiver is turned on, the 1177A-1 would automatically switch to that input. Subsequently, if the CD player is then turned on, the switcher would sense the presence of the new source, and switch to that input.
Interestingly, this works even if the first source is not turned off, which is a great feature, because some devices, like satellite and cable boxes, continue to transmit a digital audio carrier even when they are turned "off". Obviously the auto-select feature cannot work if more than one source refuses to stop transmitting a carrier, so if you have a situation like that, you might be better served by a switcher that can be controlled via IR remote.
Assuming that most of your devices actually do turn off when not in use, it works very well. And regardless of which input is active, the switcher will simultaneously output both optical and coaxial digital audio from that source. Being a digital switcher, the 1177A-1 is capable of passing SPDIF signals in just about any format or clock rate, so it supports all Dolby Digital, DTS, and PCM formats.
The included universal power supply ensures that the 1177A-1 will work just about anywhere in the world, although customers outside of the USA will probably need a passive adapter for the plug.
Like most Audio Authority products, the 1177A-1 Digital Audio Switch comes with a one year limited warranty from the manufacturer.
Multi-color LEDs on the front panel indicate "auto" mode and input selection status. A push-button switch for manual source selection is also included.
Here is a closer look at the front panel.
We have attempted to capture the subtle qualities of the finish in this back-lit photo. There is a subdued metallic appearance to the nicely textured finish. It is difficult to capture in a photo, but easy to appreciate in person.
This close-up of the back panel clearly shows four optical TOSLink digital audio inputs at the upper right, with a corresponding coaxial digital input just below. The output connectors are situated on the left side, with the power input connector just to their right.
Here are the items that are included in the box. Beginning at the upper right is the 1177A-1 unit itself. Moving in a clockwise direction, you can see a universal power supply, and an installation instruction sheet.
Here is a closer look at the labeling on the included universal power supply. This power supply will work with just about anywhere in the world, although the plug itself is intended for the USA, so international customers will need a passive adapter.
This is a typical product box.
