  • Page 5: Introduction

    1. INTRODUCTION. 1.1. General description. AEQ PHOENIX ALIO is a stereo IP audiocodec for mobile applications. It is easy to configure and operate, and integrates a digital mixer with 4 analog inputs. It features independent bass and treble control for each input, adapting the characteristics of each speaker’s voice, or correcting the defects of external signals.

  • Page 6: Available Encoding Algorithms

    AEQ also offers two SIP servers free of charge as a standard service for the users of Phoenix ALIO. One of them is configured as main and the other is provided as a backup. More information can be found in Appendix B.

  • Page 7: Block Diagram

    1.4. Block diagram. 1.4.1. Internal diagram. The unit’s internal design is organized in several functional modules that make Phoenix ALIO audiocodec a complete IP communications platform. The unit is provided with a professional quality analog audio input and output system and a versatile audio matrix with processing capabilities.
