- Will the LEDs flash directly after power-on?
Yes, the leds flash directly after the power is on.
- What happens without input signal, with unbalanced cables connected or switched to the digital input?
The leds are flashing in the same way. Nothing changes in comparison to the previous question.
Haven´t tried using (some cheap) unbalanced cables. I will try that as soon as I get back from the office)
- What happens with another balanced source?
Unforunately, I only have the v800 in my possession as a balanced source.
- What happens with no headphone connected?
With only the power cord connected, the leds HEAD and MUTE are flashing, same as all the other situations.
With the balanced cables connected as well, the same things happens too.
The first time I put the v281 on I think I heard music for about a half or maybe one second. I didn't have my headphones on, but because of the open drivers from the hd800 I could still clearly hear music playing. After one second the headphone sockets were switched off again.
I have also tried using a dedicated power outlet somewhere else in the house. This unfortunately didn't help either. Same leds flashing.
Sometimes all three leds are flashing, including the LINE led, mostly it's only the HEAD and MUTE. I can't seem to make out when it's one or the other.
Also I triple checked the balanced cables going to the right input channels, just in case. They're good
