Product introduction
INTRODUCTION
TigerANC-II Lite is a portable standalone active controller without the need of a host PC. All control parameters can be set through an embedded touch screen where the control status also can be viewed. The hardware mainly includes a high-end float-point DSP, which is in charge of the core control algorithms, and an ARM chip, which is in charge of the human-machine interface. The controller also benefits from the ultra-low latency of AD/DA conversion, which makes it possible to realize a compact ANC system for many latency critical applications.
OVERVIEW
Fig 1. TigerANC-II Lite
TigerANC-II Lite is an off-the-shelf equipment which can help users establish an active noise control (ANC) system efficiently with other peripheral devices provided by Antysound. TigerANC-II Lite supports up to 4-channel centralized control and 3-channel decentralized (mono-channel) control.
