The scene
School Radio · StudioThe school radio interrupts a rehearsal to announce that the concert is cancelled. The news is false, and the message came from one of the studio's three microphones.
The voices sound similar through the console's filter, so recognising the speaker is not useful evidence. The technical recording preserves a simpler detail: the physical channel through which the announcement entered.
What we know for certain
One of these three people broadcast the message from their assigned microphone. There were no changes of station, played-back recordings, remote connections or channel reconfigurations. The technical recording correctly identifies the physical source, even though the filter alters the voice.
The three accounts
Aina Soler
Presenter«I stayed in front of my microphone at the first station.»
Beto Gil
Music technician«I did not touch anyone else's microphone.»
Celia Rius
Script coordinator«I was reviewing the text, not cancelling the concert.»
Examine the evidence
0 of 5 openedOpening these five clues does not cost points.
01The technical recording
The false announcement is marked as input from channel 3. The number identifies the connected microphone, not the order of contributions.
02Aina's station
The microphone at Aina's station was connected only to channel 1.
03Beto's station
Beto's assigned microphone used channel 2 throughout the rehearsal.
04Celia's station
The microphone in front of Celia was the only one connected to channel 3.
05The unchanged console
The wiring photograph and configuration log confirm that the connections stayed the same before, during and after the announcement.
