The P561 Audio Encoder features MPEG-4 Advanced Audio Coding (MPEG-4 AAC) and MPEG Layer II encoding capabilities. All of the common bit rates and sample rates are offered to enhance the IP delivery of audio.

The P561 is an audio encoder for up to eight stereo channels (encoder channels). The unit is built in a compact 19” 1 U housing. It is DSP-hardware based and highly energy efficient (< 2W per stereo channel). The P561 is capable of transporting elementary streams over IP and DVB-compliant MPEG-2 transport stream output via IP or ASI. Several configurations are available to adapt the audio input configuration to the network requirements in a flexible way.
