2. FEATURES
• Permits use of not only dedicated lines, but also the Internet, which greatly reduces operating costs when
transmitting audio signals to remote locations.
• Under peak conditions with no network delay, audio signals can be transmitted with a minimal delay of about
20 ms.
• Transmission of contact control data possible.
• Transmission of serial data control information also possible.
• Simultaneous bi-directional transmission of audio signals possible.
• Simultaneous transmission of audio signals to multiple locations (up to 4 locations for unicast*
1 streaming,
64 locations for multicast* 2 streaming) possible.
• Enables loss-free audio signal transmission even over congested networks such as the Internet.
• The entire system can be remotely operated or managed from a single PC (personal computer) using the
supplied software program.
• Because audio transmissions can be started and finished via the unit's contact inputs, systems can be
configured even without the use of a personal computer.
• Designed to operate on either AC or DC power source.
* 1 UNICAST: A communications method used to transmit audio data to designated addresses in a
matched ratio of 1:1. Up to 4 channels can be simultaneously transmitted.
* 2 MULTICAST: A communications method used to simultaneously transmit a single audio data source to
multiple destinations.
