Extended AD615/SIP Encoder Application
The picture below shows a more complete scenario of possible realization of a plant.
Starting from a musical sound source like a CD player or other, the analog signal enters the audio input jack of the
AD615/SIP (the one used for the ambient music broadcast). The signal must be of "line" level like a typical output
of a non-amplified stereo player. The volume is adjusted in the external music source.
WARNING
: do not connect to this input outputs from amplifier equipment or devices that directly pilot a speaker,
the levels would not be adequate for the correct operation of the system and you may get poor quality audio quality
or you can damage the device.
By moving the system lever from the center (no transmission) to the top position, AD615/SIP begins to encode the
audio from the jack input and transmit it to one of the selected channels for LAN broadcast.
At the RJ45 proprietary input (the one used to connect a microphone base), is taken instead the audio of an
electret microphone, to be used for the transmission of announcements by an operator. The microphone is
powered directly from AD615/SIP (note that it is not a Phantom power, suitable for commercially available
microphones, then it is necessary to have the accessories provided by Tema for generating announcements
messages).
To broadcast the message (which AD615/SIP will send on the second address/channel that has priority over
music) it is necessary to move the system lever down and keep it in this position for the duration of the
announcement. With the microphone base, instead, use the suitable control buttons.
The various AD600 systems connected to the network and set to receive the streaming audio encoded by
AD615/SIP will reproduce the sound from the sources on the various loudspeakers set up in the room to be
sonorized.
