Help with Dip Switches

[PaulX101]

Hi what would you recommend setting the Dip switches when coupled to a Ortofon Quintet Red MC Cartridge,probably unnecessary but the deck is a Proj-ect Evo Classic, A Nad C700 Streamer,a pair of focal 906 speakers & BK P10 150 Gem Sub.
Many thanks

Gain - S3 on
Loading - S2 on, or possibly S3 on, try each and see.

Red MC
Internal impedance, DC resistance 7 Ohm
Recommended load impedance >20 Ohm

Ortofon Quintet Red (Low-Output MC):
Input impedance 20-50-70 ohms
Input gain 60dB

So which dip switch settings should he use??

You took the words out of my mouth

What makes it worse is that the manual also offers
Loading:
Dips 1&2 on = 1.1nF / 33 ohms
Dips 1&3 on= 1.1nF / 100 ohms
Dips 1&4 on= 1.1nF / 1K ohms

Odd, because that's different to what it says on the base, or maybe not....
I would ignore switch 1
However, once you have Gain set correctly, you play with Loading and choose what seems best.

Ok thanks Al ears, I shall give your 1st suggestion a go, and see how that sounds, If not I will play around with it and see what happens

Worth a try. Usually loading is only a recommendation.
First time I have seen nF used on a phono stage....

Loosely speaking the ‘loading’ switches turned on to the right is what MC needs, while turned off to the left is for MM. [Your pic shows it set for a low output MM]

S1 represents the capacitance, while S2, 3, and 4 represent the impedance. The former is measured in fractions of a Farad; the latter in Ohms. (Nano is a billionth, hence a lot more than Pico which is a trillionth!)

As Al says, play around as you cannot harm anything. But turn the volume down when switching in case it generates a click or thump.

Ortofons seem to like low impedance, so I’d begin at Dips 1&2 on = 1.1nF / 33 ohms. And S3 for gain, unless that’s too quiet, when S2 will be louder.

Enjoy!
