I buy sound card ESI Julia, would like to learn from you correct method of connection Julia to transmiter by MPX.
And also options ASIO for Julia.

You shouldn't need to do anything special, just connect one or both output channels of the Juli@ to the MPX input of your transmitter.

The only thing that's really important is to use good quality cable, and keep it as short as possible. Longer cables can cause phase shifts, which reduces the stereo separation and could introduce unwanted peaks in the signal. (The difference between a 5 m and a 10 m cheap consumer grade cable can already be heard in the audio).

Please tell me what of this conection is correct ?
Type of connection :
1- Unbalanced Part- Left unbalanced OUT > MPX IN FM Transmiter
2- Balanced Part - Left Balanced OUT > MPX IN
3 - DIGITAL PART - Coaxial OUT > MPX IN
In the technical description of sound cart i read that 192 kHz support only digital out ....
"Sampling Rate : 44.1,48,88.2,96,176.4,192KHz(176.4,192kHz only coaxial)"

Depending on your transmitter, you should use one of the ANALOG outputs - the digital output does NOT support more than 96 kHz (so your technical documentation appears to be incorrect...?!?).

Balanced is apparently better, but only supported by a very limited range of devices - so unless your transmitter supports it (which is VERY unlikely), just use the normal unbalanced output.

About other sound cards: I have never done a test to compare different sound cards, so I cannot tell you how other cards work. I have never tried the Maya - given the specs it should work, but I don't know how good it is.

I Understand that:
Left Unbalanced Output>MPX IN - is good. I Use 6 meter quality cable, it is normal ?
And Now please tell me corect settings Julia in Stereotool :

Below "Enable ASIO" select the Juli@ instead of ASIO4All.

As sample rate select either 176400 or 192000 (no difference in quality, 176400 uses a bit less CPU power so you should probably choose that).

"Bypass sound card, use ASIO channels":
- INPUT depends on your setup. 1+2 (analog input) is probably ok.
- For FM Output, use channel 1 (left), 2 (right) or channel 1 + 2.

For clarity:
- Juli@ channels 1+2 are ANALOG input/output L/R
- Juli@ channels 3+4 are DIGITAL input/output L/R. You can use these for input, and for normal or low latency output, but not for FM output.
- Channels 5+ don't exist for the Juli@ card.

RDS: You need to split this into 3 parts, so you'd get something like:
3s: TVOE/2s: RADIO/2s:101.4 FM

MPX doesn't do anything with the sound quality, it's just the name for the signal that contains stereo and RDS information.

Please read the help text: http://help.stereotool.com/fm_transmitter.shtml
