No internal differences.

Hi there! Is there any difference between FE and non-FE versions?

Based on the previous post I would guess not

Has anyone got a chance to compare 280 with 181?

Hi there! Is there any difference between FE and non-FE versions?

The difference between v280 and v280FE lies in the back panel and pre-gain switch.
The v280 has pre-gain switches arranged separately between the left and right XLR and RCA terminals, and has gains of -12, -6, +6, +12.
The FE has pre-gain switches grouped on the right side and has gains of -18, -6, +6, +18.
(Drop sells both v280 and FE, so it's easy to understand by comparing the back photos of each.)
The new generation violectric amplifiers have gains of -18, -6, + 6, +18, so the FE seems to have been given the same choice.

Hello Everyone. I have a v280 and was wondering if anyone is using it with the new DCA Stealth? If so how well do you think the two match up?
Thanks.

Can someone send photo where fuse placement?

From manual seemed positive and negative phase go to opamp from xlr. Do I benefit better snr thd etc if connect my dac to amp via balanced?

 

[NoNameNPC]

I cant find what opamp used in V280.

Can anybody clarify what the manual means when it says when the RCA and XLR inputs are both present, RCA has priority? I have been using the RCA as output buffers, but I'm thinking of running my RME into my V280 and the XLR inputs are already used for my Brooklyn DAC+

Does it mean when you plug cabling into the RCA jacks there is some physical mechanism that turns off the XLR input, or is it that when the amp detects signal on both inputs, it uses RCA (I hope)... thanks

If you set the rca as inputs again (from inside the unit as I understand you changed them to output/throughputs) then from what you have written (“rva will have priority) if both rca and xlr inputs have been plugged in then the rca will be the one being used by the unit

Thanks. This doesn't make sense to me but it's what I thought. So you have to unplug the RCA cables for the XLR connections to be used, even when there is no input on the RCA cables?

Actually try that out.
If you change the rca to output mode and you have the rme plugged in to the v280 but turned off then surely because no signal is being fed into the amp the xlr‘s will be operating. But i am no engineer.

it won’t hurt the amp - it’s the only way to confirm i guess

Well @Fegefeuer knows everything so I expect a clue stick is imminent

Yeah, of course I will eventually try it but it's easier if somebody knows before I pull the gear out and start switching cables around. Space is tight here...

It's a physical thing, independant of any signal being played. That's how it is. Plug in the RCA and XLR is quiet.

Thank you! I was thinking that might be it from my memories of working on (destroying) receivers in the 1970s.

So I might be looking for another desktop amp for my RME...
