Tema AD615/S digital IP PoE Encoder converts an analog audio signal from any external source into digital audio streaming in Multicast channels for audio signal distribution over LAN. Tema AD615/S is ideal to generate background music on the LAN in any environment (offices, establishments, public places and outdoors) with the possibility to make announcements.

FM radio tuner, CD-DVD player, MP3 player, Smartphone and Tablet, Sound Blaster Sound Card output, etc. can be connected to the device to convert the analog audio into digital audio streaming. AD615/S also has an input for connecting an external microphone with which it is possible to launch an announcement in a Multicast general call on all IP speakers connected in the network.

Audio Streaming Codec
AD615 / S offers the possibility to choose the most suitable Codec according to the audio quality and LAN bandwidth required. The following codecs are available: G711, G722, Linear at 16KHz / 24KHz / 32KHz for maximum audio quality.

AD611-AD612 manage up to 5 Multicast channels in LAN at priority levels to allow the diffusion of background music on the loudspeaker network. The generation of music programs in audio streaming can be managed from a PC of the LAN / WAN network with specific software or from specific Encoders.
