The TXS25-4 Evaluation Kit is a complete amplifier
evaluation system for the TXS25-4 digital amplifier module.
Audio system designers can quickly evaluate all of the
features and functions of the TXS25-4 design with this
system.
This system offers the ultimate in configurations,
digital/analog I/O and power supply connection. It offers
headers for all digital audio inputs and outputs so that the
system designer can quickly and easily "wire-wrap" into the
2
board. This enables any I S/Left-Justified digital audio
source to be delivered from any digital audio source such as
an HDMI™ receiver or a Media Networking Processor and
input into the TXS25-4 amplifier with minimum effort. A
header is also offered for the control communication bus
(2-wire interface), which enables fast connection of a system
microcontroller for rapid prototyping.
The D2Audio Canvas GUI software simplifies system design
with an intuitive, audio-centric user interface with
"point-and-click" options on a Windows™ PC. Organized
processing blocks are included for audio input selection,
Tone Control, Crossovers, Parametric Equalizers, Adjustable
Time Delay, Signal Limiter/Compressor, Volume Control,
Loudness Contour, and Independent Level Control.
