Hi,
has anyone a Transrotor Turntable with a MC Merlo cartridge?
It is my first MC device and it is standing here with me being afraid to test it as it is without properly configuring it in the D220 configurator.
maybe someone can help here?
Regards
Kian

I agree with Axel and daved. With an MC cartridge you normally want to phono stage capacitance to be as low as possible, so set to zero. Some people would go as far as trying to re-wire tone arms with low capacitance cable for use with MC's, but simply setting the Devialet to 0pF works well with MC cartridges and is a lot easier!

hmm, I do not feel comfortable to just do something without understanding why:
what does load capacitance do and in how far does it impact the sound or cartridge?
why do you say to put it to 0 whereas the official manfucturer specifies a range of 100-500pF?
And:
1. What is uVRMS?
2. What impact does uVRMS have on sound and cartridge?
3. What differences can I expect when choosing a value between 0 - 5000uVRMS?

what does load capacitance do and in how far does it impact the sound or cartridge? ->
Load capacitance makes little difference to MC cartridges - Try changing it and see if you notice a difference.
why do you say to put it to 0 whereas the official manufacturer specifies a range of 100-500pF? ->
Because the tonearm cable has some capacitance (usually more than 100pF) and any load capacitance is added to this.
1. What is uVRMS? -> micro Volts RMS - this is the output voltage of your cartridge 0.5mV = 500uV
2. What impact does uVRMS have on sound and cartridge? -> it determines the gain for the phono input, too high gain on the phono stage (i.e lower uVRMS value) will cause the ADC to clip (Bad!), too low and you'll lose signal to noise ratio (not so bad as you have 24bit dynamic range to play with, Hence start at around the stated output for the cartridge + a bit to ensure you don't clip (i.e. 550-600uV)
3. What differences can I expect when choosing a value between 0 - 5000uVRMS? -> (see above) ~0 = loud and distorted, 5000 = very quiet!
Cheers
