We get the first bulk of Tronsmart vega s89 in stock,and finish this passthrough review. Here is my test device:
2 Yamaha RX-375 5.1 Receiver
3 Yamaha NS-P40 Speaker
I test different 1080p mkv, ts format local video file, and use built-in XBMC to play them!
First test the HDMI Passthrough, here is how i connect the tronsmart with receiver and TV.
I use one male to male HDMI Cable to connect tronsmart vega s89 and the yamaha receiver( use the hdmi in port in receiver) and then use another male to male hdmi cable connect the receiver with TV ( use receiver’s hdmi out port).
and on the tronsmart vega s89 setting, i change the audio output to hdmi passthrough, and enable passthrough on xbmc.
Here is the test result:
1 Dolby (AC3) 5.1 HDMI passthrough ——–OK
2 DTS 5.1 HDMI passthrough——-OK
3 DTS-HD HRA 5.1HDMI passthrough—–OK
4 Dolby True-HD 5.1 HDMI Passthrough—can’t work, receiver just show 2.1, not 5.1;
Second, let’s test the optical passthrough,here is how i connect:
use male to male hdmi cable to connect tronsmart vega s89 and the TV. and then use the optical cable to connect vega s89 with receiver.
and on the tronsmart vega s89 setting, i change the audio output to optical passthrough, and enable passthrough on xbmc.
here is the test result:
1 Dolby (AC3) 5.1 HDMI passthrough ——–OK， but with noise.
2 DTS 5.1 HDMI passthrough——–OK， but with noise.
3 DTS-HD HRA 5.1HDMI passthrough——OK， but with noise.
4 Dolby True-HD 5.1 HDMI Passthrough—same as hdmi passthrough problem, can’t passthrough 5.1.
So, seems the HDMI passthrough is working ok, but there is something problem with optical passthrough. I have reported this problem to factory, and check if they can fix it.
any questions, feel free to leave message here!
