Pre-out level setting; mV < ——which setting?

#1

I have a question about the eight options in the pre-out level settings expressed in millivolts. When connecting to a power amp I’ve noticed pleasant sonic qualities when I go to the upper limit of the settings around 500 mV. I’m connecting to an Boyuurange A-50 MKIII 300b tube power amplifier with an input voltage of 750 mV.

Is it best to shoot under with the 500 mV of the rose? Or is it safe to choose according to sonic taste?

I’m wondering if there is an upper limit where I might be damaging or otherwise running the power amplifier too hard.

Thank you

Hello.
The input sensitivity of the amplifier is a condition for the amplifier to produce the maximum output.
When the input sensitivity of the Amplifier is 600mV…

If the level of the source is less than 600mV, the amplifier will not produce the maximum output. Conversely, even if a signal with a level greater than the input sensitivity is input, the amplifier’s amplification level is reduced and there is no problem in use.
However, if you put in an input greater than 600mV and raise the volume of the amplifier to the maximum, clipping will come out, so just be careful about this.

In general, amplifiers have a device in case of receiving an input greater than the input sensitivity, but it is recommended to check as there may be differences between models.

Thanks, If I am interpreting your reply you’re saying that I can go ahead and choose outputs above the rated input (of 600mV) and choose Rose devices’ 1000, 2000 and 3000 mV, as long as I am mindful of distortion in setting overall volume.

That the various input voltages cannot damage the power amplifier, if used with common sense.

Is this correct?

Can You help me to choice correct setting for my esoteric f-05?

I’m sorry for the late reply.
Pre-out level setting can be set according to the input value of the amplifier you are using.

Thank you

For reference, my AVR (x4500h) has an input sensitivity of 200mv. Setting the preout level to 200mv is far too low a volume range. I have mine set on 5000mv which is comfortably loud at medium volume.
