3. Features
The innovative Enersound CS-300 Conference and
Discussion System is equipped with a high-quality ECM
capsule, intelligent automatic mixing technology and
integrated acoustic and mechanical design, providing a
turn-key solution and delivering consistently natural,
feedback-free audio performance in any environment.
The CS-300 Conference and Discussion System is ideal for
discussions and meetings of up to 150 people.
A CS-300 Conference and Discussion System consists of:
• (1) Control and power supply unit (CU)
• Maximum of (50) delegate or chairman units
• Peripheral audio and/or telecommunication equipment
The CU (Control Unit) is the core of the discussion system,
which controls the microphones of the chairman and
delegate units as well as the other audio input and output. It
also supplies the power for up to 50 delegate and chairman
units.
The delegate unit enables attendees to participate in a
discussion by speaking through a microphone controlled
by a microphone ON/OFF push-button and listening to the
discussion through the internal loudspeaker or external
headphone.
The chairman unit not only provides the same function
as the delegate unit, but also supports the addition of a
“priority button,” which enables the chairman to control
the discussion by temporarily or permanently overriding
and deactivating all active delegate units.
