INTRODUCTION Welcome How to Use This Manual Congratulations on your purchase of the Vortex EF2211/EF2210! This is a reference manual for your EF2211/EF2210. Information specific to the EF2211 or EF2210 will be noted as such. The major difference between the EF2211 and the EF2210 is that the EF2210 does not have a phone interface. This manual is structured to provide the information you need quickly and conveniently. The following is an overview of each section: · · · · Introduction Pre-Installation includes information about the contents of the box, tools needed for installation and front and rear panel descriptions. Installation covers connections of inputs/outputs and calibration of inputs of the EF2211/EF2210. Integrating the Unit Into Your System describes adjustments to take into consideration when integrating the EF2211/EF2210 with surrounding equipment in your system. LCD Menu Structure describes an overview of the LCD menu structure and also gives a system overview of features and options available. Troubleshooting helps to debug problems with installation. Technical Specifications provides the technical specifications of the EF2211/ EF2210. Conference System Design gives suggestions on topics to consider when designing your system. EF2211/EF2210 Block Diagram shows the inside of the EF2211/EF2210. Connector Pinouts shows pinout diagrams for EF2211/EF2210 input and output connectors. Warranty Information Definition of Terms explains terms used in this manual, as well as terms used in our technology of echo cancellation, noise cancellation, and audio conferencing. · · · · · · · · About the EF2211/EF2210 The EF2211/EF2210 features industry-leading acoustic echo cancellation technology, which keeps received audio from being re-transmitted to its original location, and patented noise cancellation algorithms which dramatically reduce ambient noise in the audio sent to other sites without affecting speech quality. Also included in the microphone input is a neural network Automatic Gain Control that reacts only to valid speech patterns to bring voices within desired levels. AGC controls are user-adjustable, as are settings for the 5-band parametric EQ offered on all input and output channels in the EF2211/EF2210. The EF2211 includes a telephone interface with ambient noise cancellation, which can dramatically improve the receive audio quality on phone calls. The EF2211/EF2210 may be programmed directly from the front panel, or through our Conference Composer software (included), which programs the unit via RS-232. The unit may additinally be controlled via external RS-232 devices.
