Encod./Quality 0 1 2 3 4 5 6 7

MPEG1 48kHz 88 96 104 120 144 160 176 192

MPEG2 16kHz 35 38 44 48 56 64 80 96

The above table shows only the average bit rates for 16

kHz and for 48 kHz. As the “stereo” adds about 20 to 30 percent when compared to “mono” other

sampling frequencies can be calculated using the previous “mono” table.

Advanced Encoder Settings

These following settings are for advanced users only. Detailed information about the Encoder

Settings can be found in the Micronas MAS3587 MP3 encoder data sheet.

A/D ampliﬁer gain

Choose the desired gain (“-3” up to “19.5” dB) for the line input A/D ampliﬁer.

Note: The line input sensitivity has changed from 2 Volts peek to peek on legacy devices to 4 Volts

peek to peek on the new “Instreamer 100” (less sensitive).

MP3 Frame CRC

If set to “enable”, the encoder will include the CRC-16 in each MP3 frame.

MP3 Bitreservoir Mode

The “Bitreservoir” is used to compensate the differences between the predeﬁned frame sizes. If set

to “used”, the encoder will use the bitreservoir. Leave the setting to “kept empty” if you use RTP

streaming or need low latency on the transmission.

MP3 Channel Mode Extension

“Enable” or “disable” the MS-Stereo encoding (for stereo only). When set to “disable MS-Stereo

encoding” only mono will be encoded and therefore the bandwidth used is minimized.

MP3 Copyright Protection

“Enable” or “disable” the copyright protection bit in the MP3 stream.

MP3 Stream Type

Select between a “copy” or an “original” in order to set the appropriate bit in the MP3 stream.

MP3 Emphasis

Select emphasis “none”, “50/15 us” or “CCITT J.17”.

3.3 Streaming settings

These settings adjust the streaming mode, parameters and destinations.
