Hi guys. I have a RS151 since yesterday and I love it so far.
At the output menu of the RS151you can setup the pre-out level for your amp. My amp is a my Naim Supernait 3. And I will use his RCA unbalanced input
I can choose for 1000mv 1500mv 2000mv 2500mv or 3000mv. Does anybody know what to choose? I have no idea.
No idea if it can damage your amp when you pick the wrong one…
Hope one of you guys can help me out with this one
I have both RS130/RD160 and on the RD160 I also have to set the output for the input of my preamp/amplifier.
I read on the manufacturer’s data sheet, NAIM:
Line-level input (RCA/DIN): Impedance 47 kΩ, 2 V, Input sensitivity: 130 mV
On RS151’s documentation you can choice output level in the first lines : 100 or 300 mV :
Try the minimum output on RS151 and turn your amplifier to the lowest volume, gradually increasing it…
Hopefully, there won’t be any audible distortion.
Thanks for your response. This is what my menu tells me…
So would you start at 250 ? And rise after that till distortion comes? Doesn’t that Damage the Naim.
Did you change the output yourself ?
Hello everyone!
Until yesterday, I had a Rose RS250A HiFi set to 1000mV (500mV per channel), and with my PrimaLuna EVO300 Hybrid, I’ve never had a problem. Starting today, I’m starting to use a Rose RS151 HiFi, and for now, I have it set to 1000mV. I feel like the volume is a little low, and I’m hesitant to change it to 2000mV (1000mV per channel).
Yes, I can tell you that the audio is impressive compared to my RS250A, which was already spectacular.
As for the FIR Interpolation Phase Filter , I just set it up the same as the RS250A, Minimum Phase Slow Roll-off Filter and it’s crazy, awesome! Everything sounds very analog.
Good luck and go all out.
It seems that it does not work at all at my place. When I choose one of the options I hear no difference and when I go back to output settings the function is back to off ?!!!
I also do not see the Minimum Phase Slow Roll off filter (see my picture). Can you tell me how you did change the settings at your place? Maybe I am doing something wrong …
I just did find out that you only can change these settings in the menu of the player and not in the app. The input Sensitivity of my Naim is 130 mV. So I have set the pre-out to the lowest setting of 250 mV. It seems to go ok this way and now I also could change the FIR settings. I do not know if i should go any higher with the pre out settings …
The naim site says this: Line level input (RCA) Impedance 47k, 2.0 V Typical, Input Sensitivity 130mV
What do you or anybody else think? Thanks for trying to help me out. Much appreciated 
Naim says 2 V typical and 2 V (or 2000 mV) is very typical for a pre-out setting, so I would suggest starting there.
100% agree. I just upgraded my RS151 from 1000mV to 2000mV, and my PrimaLuna volume is at 9:45 AM, if you think of it like a clock.
Filter Minimum Phase Slow Roll Off Filter, It will give you a warmer, more interesting audio with an analog audio feel.
I’m sharing a photo so you can see how I had it configured on the RS250A, which worked perfectly. I set the same setting on the RS151, but instead of 1000mV, I changed it to 2000mV.
If you see the specs of the Naim (see pic) they are talking about 2.0V typical and input sensitivity of 130 mV. What is the setting to aim for. In the meantime I Tried 1000 and 2000 and both work. Of course the volume is louder with the last setting but no clipping so far.

That’s all very interesting to me. Should I also start with 1000 mV? Do you have any suggestions for a good starting point?
Considering my amplifier has the following specifications:
Input sensitivity: 1.66Vrms
Input impedance: 22KΩ
Signal to noise ratio: 124.6dB
Dynamic range: 124.7dB
THD distortion: 0.0020%
THD+N distortion: 0.0097%
Sounds good to me, 1000 mV It works at my place …
I understand what you’re saying. Look, if 1000mV works for you, then go ahead and set it to 1000mV. In my case, I’m going to leave it at 2000mV, given that compared to my PrimaLuna Evo 300 Hybrid, the 2000mV setting sends a signal with less noise, and using the volume at 8:45 a.m. (think of the knob as a clock), I don’t experience distortion or anything like that.
I am going to experiment with that. 8.45 is also my normal volume. Thanks for the input
You’re not making it sufficiently clear whether you believe that voltages are summed across channels, or just have no clue what balanced vs. unbalanced means.
Sure, let’s kill the frequency response in the treble. Not that you would be able to tell one filter from another in any case.
What would you do Boris if it was up to you. I see that you do not agree with JMBARG.
What mV setting and what filter would you suggest?.
2V (2000mV) is more or less the standard for unbalanced (and 4V for balanced) connections, so I would start there. If it gives you sufficient output volume and there’s no noise, it should be good enough.
If you want to tweak it more, get a track with digital silence or better yet -120db tone. Set the output level to the point where there is no noise coming from the speakers even at the maximum volume, and, if using the test tone, you can just hear it from the speakers.
Note that not every preamp/amp has enough gain to actually make -120db signal audible. If you can’t hear anything, leave it at around 2V, as long as there’s no noise.
Boris, thanks for existing! What would we do without you?
You probably would be sticking a fork into the wall socket.
He guys come on !!! No fights here. We are out here to help each other
