6 System Operation

The Conference

ONE™i Discussion System can be operated in either of the two operating modes described

below.

6.1 Manual Mode

In manual mode, each console microphone is activated by simply pressing the PTT button and deactivated
by pressing this button again. However, the number of simultaneously active microphones is limited to a
value between one and eight according to the limit set in the menu of the chairman console.

If the maximum number of active microphones is set to one, the chairman console displays the length of time
that the microphone is active.
Note: In order to avoid feedback, the overall volume is automatically reduced as the number of active
microphones increases.

Pressing the CANCEL button on the chairman console deactivates all other microphones in the system. By
pressing and holding the PRIORITY button, the chairman can temporarily deactivate all other microphones in
order to make an announcement. The lightrings on the temporarily deactivated consoles blink as long as the
priority function is active.

6.2 Automatic Mode

In Automatic mode with IntelliMix

®

-technology, each console microphone automatically activates when a user

speaks into it. The Conference

ONE™i Discussion System automatically attenuates (turns down) any

microphone not being used, greatly reducing the excess reverberation and feedback problems associated
with conventional multiple-microphone systems. When a new talker begins speaking, the IntelliMix

®

system

immediately selects and silently activates the nearest microphone, within 4 milliseconds. IntelliMix

®

signal

processing enables the Conference

ONE™i Discussion System to provide clear, natural voice pickup, and

significantly reduces the problems of “hollow” or “muddy” sound, as well as insufficient gain before feedback.

The CANCEL and PRIORITY buttons on the chairman console retain their full functions in automatic mode,
the PTT button on delegate and chairman console will function as a mute button (push to cough).

As a special feature, when you connect a Shure SCM series automatic mixer to the LINK input on the rear
panel of the power supply, it directly interfaces with the automatic regulation functions of the
Conference

ONE™i Discussion System with IntelliMix

®

circuit.

Please note that the audio signal is only transmitted from the SCM series mixers into the Conference

ONE

Discussion System and not from the Discussion System into the connected SCM series mixers.
