Signal-Sensing AutoSelector Digital Audio Switch

The
totally redesigned 1177A retains all the features of the
original 1177, but adds an attractive, all-metal cabinet, and a
new circuit board layout. The 1177A features both digital
coaxial and digital optical inputs and outputs, and
automatically outputs the selected audio source in both formats
simultaneously.
Audio
Authority Digital Audio switch provides a solution for consumers
who need multiple digital audio sources to sound systems with limited audio inputs.
The Model 1177A is a compact switching system which allows the output of 4 digital audio
sources to be connected to the digital audio input of a home theater receiver or
amplifier. Additionally, the 1177A accepts both optical signals (TosLink) and coax
signals (S/PDIF RCA) and automatically converts them to provide both types of outputs
simultaneously to
the sound system, thereby eliminating compatibility problems between products with
differing digital connections.
The model 1177A also incorporates proprietary
circuitry to monitor the 4 sources connected to it for the presence of a digital signal,
and selects the active source automatically. A manual select button is provided to
override the 1177A's automatic selection.
