摘要： The public address system 1 comprises a transmission medium 4 having a loop shape and a plurality of loudspeakers 3. The transmission medium 4 transmits a transmission signal therethrough in a first direction and in a second direction opposite to the first direction. The transmission signal includes a communication signal having a predetermined frequency range and an audio signal having a different frequency range than the communication signal. The public address system 1 further comprises a first filter unit 51 connected to the transmission medium 4 that is configured to filter the transmission signal to attenuate the communication signal and output the audio signal. The first filter unit 51 is connected to the transmission medium 4 such that the communication signal is prevented from transmission in the first direction while the communication signal and the audio signal are transmitted in the second direction.

摘要： The public address system 1 comprises a transmission medium (4) including a main transmission path (4-1) and at least one branch transmission path (4-2) branching from the main transmission path (4-1), a plurality of loudspeakers (3) connected to the transmission medium (4), a first branch monitoring device (10a), and a second branch monitoring device (10b). The second branch monitoring device (10b) only transmits a transmission signal (S-2) from the main transmission path (4-1) into the branch transmission path (4-2) when the second branch monitoring device (10b) has detected that there is no transmission of the transmission signal (S-1) from the branch transmission path (4-2) to the second branch monitoring device (10b).

摘要： The public address system (1) comprises a transmission medium (4) configured to transmit a communication signal, a plurality of loudspeakers (3), and a plurality of communication controllers (10) arranged in parallel on the transmission medium (4) so as to correspond to the loudspeakers (3) respectively. Each of the communication controllers (10) includes a first filter unit (11) configured to prevent passage of the communication signal, a receiver (15a) arranged so as to receive the communication signal before the first filter unit (11), a controlling unit (13) configured to determine whether to transfer the communication signal received by the receiver (15a) onto the transmission medium (4), and a transmitter (16b) configured to transfer the communication signal received by the controlling unit (13) onto the transmission medium (4) according to the determination by the controlling unit (13).
