For my request, the device is ideal, are connected:
- Blu Ray player via HDMI
- Amazon Fire TV via HDMI
- HD cable box, only sound via optical fiber
- IPhone or iPod via USB
- Full HD LCD TV
- 5.1 Set HKTS 9 Harman Kardon
Everything works fine, the surround modes are quickly adjusted via the remote control.
All settings are either directly accessible on the device display or a bit more comfortable with a menu screen. Here should be placed in the AV input of TV, another cable (RCA).
The sound is great, no noise or any noise can be heard (yes something is worth mentioning because in more expensive AV Reveivern Harman Kardon that is not a given!).
Allegedly, it is probably also possible the HDMI signal loop through even when power is off - this I need but then probably times by the detailed manual on the supplied CD ransack.
I would recommend this amp.
