with the communication interface selected. For example, uncompressed audio
can only be selected when the NET is set to IP. In the following description
these restrictions are outlined for each algorithm.
Selecting the algorithm.
For Encoder 1 the following options are available:
 AUT : Automatic Mode. This means that the Encoder adopts the same mode
as the Decoder. (This is equivalent to the automatic dependent mode of the
Pronto 3).
 PCM : Line audio without compression.
 G711 : Compatible with the telephone standard
 G722 : Low delay Algorithm appropriate for high quality voice.
 MPL2 : MPEG 1,2 Layer II.
 MPL3 : MPEG 1,2 Layer III.
 AAC2LC: AAC MPEG 2 Low Complexity.
 AAC4LC: AAC MPEG 4 Low Complexity.
 AAC4LD: AAC MPEG 4 Low Delay.
 aptX
TM
: Proprietary algorithm based on ADPCM, with very low delay.
NOTICE – RESTRICTIONS ON THE DIFFERENT NETWORKS
 PCM is only available if NET = IP.
 G711 is only available if NET = ISDN or IP.
Next there follows the parameters and restrictions associated with each
algorithm.
