Advanced information

4.3.1 IP Audio Module

The configuration of this module is via standard web

pages. Using a WiFi device accesses the console as

follows:

1. Connect   the   cable-bridge   joining   the   RJ45

"Ethernet streaming" to "LAN 3G".

2. Turn on the console MX2400

3. Enable   the   "streaming"   button   on   the   front

panel.

4. Using a Laptop, look for WiFi networks:

5. Connect to the "MX2400" network (password:

streaming)

6. Open a Web browser and enter 192.168.0.90

(fixed IP of the default console). The following

screen appears:

It presents the state of the streamer module MX2400.

The most important parameters are: 

•

The audio level, updated each 3 seconds.

•

The state (transmitting or stand by).

At right, a brief  help.  Once admitted to the general
screen, press the button  

[Configuration]  

to indicate

the  destination  address.   Here   you  can   access   to   2

options: 

[Basic Settings]  [Advanced Settings]

4.3.2

Audio

Set   the   audio   quality.   Available   options   are:  

PCM,

uLaw, MPEG 1 (layer 3)

 and 

MPEG 2 (layer 3)

. Mono

or stereo.

Allowing different transmission qualities (mono/stereo,

44.1/32/22   KHz,   etc.)   according   to   available

bandwidth.

The   recommended   are  

MPEG   2   (layer   3)

  at   any

sample   rate.   As   more   faster,   better   frequency

response, but requires more bandwidth.

It is also possible to choose between mono and stereo

transmission. 

We recommend 'mono' to conventional transmissions. Stereo only
applies to special broadcasts such as music or sports events of 
great importance where necessary to transmit more impact and 
realism of the environment. 

 

When you select MPEG, it is possible to define an
extra parameter called  

'quality'

  that  

determines the

bitrate 

of transmission. The encoding is of variable bit

rate (VBR). The examples listed below can be heard

on our website www.solidynepro.com 

MPEG2/Mono/16KHz/Quality=0  

generates   a   VBR

between 24 kbps and 32 kbps, preferably by the rate

of   24   kbps.   It   is   appropriated   for   transmission   of

human voice.

MPEG1(MP3)/Stereo/32KHz/Quality=4  

generates   a

stream of 96 kbps, stereo.
