\With a variety of controls at your fingertips, the Vortex EF-IR11 controller makes it easy to adjust volume, bring a telephone call into the conference, or execute custom commands. Users of Vortex voice conferencing products frequently need to move around the room. For example, a teacher in a distance learning classroom might be moving between a whiteboard and lectern, as well as walking up and down the aisles in the classroom. Users such as these benefit from simple handheld controllers such as the Vortex EF-IR11.
The EF-IR11 provides direct control of the Vortex EF2280, EF2201, EF2211 and EF2241 products. With the EF-IR11, a user can adjust volume, mute and unmute audio, activate a phone line, dial out or answer calls, or execute any of 35 macros that are user-programmed into the Vortex units. Macros could include instructions for codec controls, muting and unmuting of telephone callers or executing a preset in a Vortex unit. Dedicated buttons for two speed dial numbers (programmed into a Vortex telephone interface) make it easy to connect to frequently called locations.
