> MAGELLAN UC-AEC

MAGELLAN UC-AEC is a digital counter intercom system which allows clear and simple speech at information booth, point of sales, and receiving desks wherever glass disrupts conversation between people. This system provides Full Duplex and excellent communications through obstructions. MAGELLAN UC-AEC is the best intercom solution for applications requiring perfect voice transmission even in the most difficult acoustic conditions. The combination of this system with the induction loop antenna enables the hard of hearing people reception.

Benefits

• Clear and simple communications through glass obstructions
• Full Duplex conversations
• Anti-larsen and echo cancellation functions
• Automatic variation of the amplification level according to ambient noise levels
• Independent levels adjustments for agent and client sides

• UC-AEC – Central unit with integrated digital speech processing by DSP.

• HPU (optional) – Antivandal proof wall or desk mount loudspeaker

For MAGELLAN the DSP uses a program based on complex algoritms to operate the intercom functions:The agent has an intercom power button (ON/OFF) and a power boost button (+6 dB) with pilot lamps, in case levels are insufficient. The BMEQ induction loop for hard-of-hearing people can be adapted to all UC1 central units as an additional option.

Antilarsen function: to avert larsen effect, an echo cancellation process is used by the program to analyse and define the disturbance signal parameters and to eliminate disturbance from the usable signal. This amounts to breaking the amplification loop on one or two channels, or on both channels simultaneously.

Automatic variation of the amplification level according to ambient noise levels: the DSP measures the noise level in the hall via the client or agent microphone, and automatically adapts the gain of each channel to maintain good audibility.
Sound limiter: this reduces the sound level in the speakers when clients speak too loudly or too close to the microphone.
Level settings and sound activity detection thresholds. 

• Full Duplex
  Natural two-way communication in both directions.
• Fully Digital (DSP)
  The central unit integrates a Digital Signal Processor.
• Anti-larsen and echo cancellation functions
  To avert larsen and echo effects caused by the Full Duplex communication, an echo cancellation process is used by the program to analyze and define the disturbance signal parameters and to eliminate disturbance from the usable signal.
• Limiter
  This reduces the sound level in the speakers when client speaks too loudly or too close to the microphone.
• Automatic standby mode
  The system goes automatically into standby mode (programmable parameter) and wakes from sleep when it detects voice activity. It differentiates speech and background noise.
• Antivandal client microphones and speakers
  Client microphones and speakers are suitable for outdoor applications and sensitive areas.
• Programmable output levels
  Independent levels adjustments for agent and client sides.
• Web browser-based control
  All settings are made using the embedded web server incorporated into the central unit UC-AEC. The embedded web server is accessible via any internet browser.
