My customer has bought SX20 before. Now they'd like to integrate external audio system including echo cancellation (Biamp Nexia VC), amplifier, goose-neck microphones, wall-mounted speakers to SX20. In my opinion, this can't be implemented because there's not enough interface (only 1 audio out 3.5 mm and 2 audio in 3.5 mm for 2 mics). I wonder if SX20 can be met this requirement. If no, please recommend me the suitable model.
Thanks in advance.
Without the guarantee that it will work without any trouble; I would recommend a C40 or C60.
That said I would recomend testing if it works fine with the external sound system.
The C40/60 have an API command to disable the echo cancellation on the input port which
would most likely be required to handle the external cancellation:
Audio Input Microphone [1..2]/[1..4] EchoControl Mode Off

Hi, any one managed to connect external mic to sx20 codec ?
Trying to connect shure mxa910 using shure intellimix P300 (analogue to codec)
Using a 4pin (TRRS) 3.5mm to phoenix connector
Have tried Tip to +
R1 to -
R2 not terminated
S as shield
Have also tried to short R2 for control to fool the codec but no luck
Running on sw ver 7.3
Similar setup on Polycom gs500 works plug and play
Any assistance / advice would be really really appreciated
