Thanks Lewm, I didn't mean to sound snarky, Below is the best that I could copy and paste from the phono stage manual. By the way, there are no separate inputs for MM & MC, just the way it's put together. As a side note, I've always had a basic understanding that low output cartridges tended to sound better than high output cartridges. Yes, the idea here is to see whether or not my phono stage and tonearm are a good match for a particular cartridge.
3.0 Adjusting the ASR Mini-Basis
Before you do any adjustments inside the ASR Mini-Basis please disconnect the power cord from the AC outlet.
a) to adjust the ASR Mini-Basis, please remove the cover of the main unit. Please use a 3 mm allen wrench to loose the four screws
b) inside the main unit you find four DIP switches to adjust the ASR Mini-Basis
c) in input resistance can be adjusted at the 10 pole DIP switches
d) the gain can be adjusted at the 6 pole DIP switches
d) the DIP switches have two different settings: ON or OFF; be sure, that the switches are correctly set (when set correctly, you will hear a slight klick)
c) please set the DIP switches exactly the same for the right and the left channel
3.1 Adjusting the input resistance
The ASR Mini-Basis can be perfectly adjusted to bring out the best sound out of every cartridge you may ever use. Adjustment of the input resistance can be made from 47 kOhms for MM cartridges to 12 Ohms for low output MC cartridges.
We know from experience that if you are using an adjustment with a lower input resistance the ambiance is improved with limited dynamics, with a higher input resistance the overall performance is brighter and more dynamic, but definition and precision are limited.
You can easily find out the perfect setting for you: make an adjustment and listen to the system.
The adjustment you like best is the one you should choose!


3.2 U Adjusting the input capacity
The input capacity can be adjusted on DIP switch No. 10: position Off = 50pF, On = 150pF.
You can easily determine the value for your cartridge by using the cartridge manufacturers recommended value and subtract the capacity of the phono cable you are going to use
the result is the value you have to adjust in your ASR Mini Basis.
3.3 Adjusting the gain
The gain can easily be adjusted on the 6 fold DIP switches Gain Adjust. The switches can be combined to get higher gain. The minimal gain of +30 dB is obtained with all Dip switches in OFF, the Maximum gain of +72 dB is obtained by putting all DIP switches to ON.
To know the adjusted gain please add the following values to 30 dB :
switchNo.ON none 6 5 4 3 2 1 All1-6 Gain 0dB +6dB +12dB +18dB +24dB +30dB +36dB +42dB
Please set the DIP switches exactly the same for the right and the left channel (only exception from this rule: your cartridge has different output from the right and left channel).
