Interrupting audio source
NOTICE
This feature allows another audio source to be connected
in parallel. Its signal takes priority over the audio signal from MAIN input
sockets (F). The signal from the MAIN input sockets (F) source becomes
inactive whenever there is an input from the interrupting audio source.
NOTICE
Once the interrupting audio source becomes inactive,
it takes around 6 seconds for the main audio source to resume the
transmission.
Connect the interrupt audio source via standard RCA to RCA cables
or an 1/8" (3.5 mm) Stereo to RCA Cable (cables not included) to the
INTERRUPTING INPUT sockets (E).
