Hello,

I installed the nanoAVR HDA some days ago and put it's remote function into the Harmony control
successfully.
Thank you for this equipment, it works nicely for the moment and fits most of my requirements
(2x2 channels front mains, 2x2 channels front/back subs).

The output voltage of the HDA, determined by the AK- DAC is limited to 2Vrms, which is a bit low for
power amplifiers (Hypex classD). It would be nice to have a differential/balanced output with
~5Vrms, if possible in the future.

Questions:
1.
Up to now I use an 2:1 Octava HDMI-switch in front of the nanoAVR, which switches automatically to
the last active HDMI-input.
Is there a similar configuration for the nanoAVR possible, possibly omitting the Octava? As far as I know, the HDMI input is related to the configuration setting.

2.
A remotely controlled power off- or power-down-function would also be nice.

Thanky you!
Cheers, Timo

ANS: Unfortunately I'm afraid that we don't have such feature available in the API of our chipset.. :-(

2.
A remotely controlled power off- or power-down-function would also be nice.
ANS: unfortunately we don't have control over the DC-DC section (and would require another standby ic). I'm afraid that It's not technically possible from a hardware point of view to put unit ON/OFF.. :-(

A nice to have thing regarding input selection would be to have IR commands to select them (ie, an ir command to select source 1, and a different ir command to select source 2). The current system, with only the source switch command, is not really convenient when using an harmony remote.

Do you think this could be feasible in a future firmware update ?
