Audio Authority 1154B Digital / Analog Audio Switcher - Up-scale Design with AutoSelect and IR Remote Control Options

If you've been searching for a great digital audio switcher that is made in the USA, you may have heard about the Audio Authority 1177A.  It has been, arguably, the best and most reliable digital audio switcher in its class for a number of years.  If you've been searching for one, you may have also come to realize that the 1177A has been discontinued.

When we found out, we actually bought all of the remaining inventory that Audio Authority had available, but sadly, even that cache is nearly depleted.  The 1177A was so good at what it did that we have been having some trouble finding a worthy replacement.  But then it dawned on us - the same technology and features that the 1177A was famous for are also included in Audio Authority's own 1154B!

As far as we know, no one has ever marketed the 1154B as an audio switcher, but the fact is that it does essentially the same things that the 1177A did and more.  It has the same digital audio specifications, it has  AutoSelector functionality, and has the added bonus of also handling analog stereo audio.  And it has one other feature that the 1177A never had - it has an IR remote control!

The 1177A's AutoSelect feature did a surprisingly good job of picking the right input, and this switcher has that same feature, but there have always been some cases (with both models) where AutoSelect was less than ideal.  For example, some components continue to transmit a digital audio carrier signal even when they are "off", so that makes it pretty hard for any auto-switching logic to know when to switch.  The reality is that, as good as the 1177A was, there were times when it would have been nice to just be able to choose the source manually.  With the 1177A, one could do that by pressing the Manual Select button on the front panel, and this switcher has that same functionality, but with the 1154B, one also has the option to use the included IR remote control to select the input from a distance.

The Audio Authority 1154B can be thought of as the evolution of the legendary 1177A, bringing enhanced performance and new features in an elegant satin finished all-metal case design.  The front panel features touch-sensitive controls, including discrete buttons for each input. The 1154B retains Audio Authority's excellent AutoSelectâ„¢ feature, for the ultimate in source switching convenience, but also adds discrete IR remote control for even greater flexibility and control. Discrete IR input commands make it easy to control the 1154B with universal remote control macros.

The sleek metal casing encloses all-new electronics, featuring even higher bandwidth without signal degradation. All inputs are AC coupled to prevent DC offset problems.

With it's streamlined jack arrangement for the rear panel, the 1154B switches your choice of coaxial or optical TOSLink digital audio, analog stereo audio, and component video, for up to four sources. The 1154B can expand the capacity of any audio system.  The 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 CD player connected to input two via coaxial digital audio cable. No matter which input is active, the switcher will always output both optical and coaxial formats from that source. Please notice that while the 1154B does convert between optical and coaxial digital audio, it does not convert analog to digital, nor digital to analog.  Supports all Stereo, PCM, Dolby Digital, and DTS formats. 

Put Audio Authority's thirty-plus years of A/V design and manufacturing experience to work in your own system with the high-performance, high-class 1154B!

Like most Audio Authority products, the 1154B comes with a one year limited warranty from the manufacturer.
