The MAGELLAN intercom consists of the following components:

Client side: A microphone (MC), one or two loudspeaker (HPU) a strip for hard-of-hearing people (optional).
Agent side: A microphone equipped with control keys and pilot lamps (MAS) and one or two loudspeakers (HPU).
A central unit (UC) with integrated digital speech processing by DSP (Digital Signal Processor).
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.

For MAGELLAN the DSP uses a program based on complex algoritms to operate the intercom functions:

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.
