depending on whether it seems needed for a particular cartridge/arm
combination.
One way to determine this is to play a quiet passage of a recording at a
relatively high level with your speaker grilles off. Watch your woofers. If
they are moving in and out noticeably without there being a clearly
correlated low bass sound, you should probably engage the 20Hz HPF.
Otherwise, you are wasting both amplifier power and woofer excursion
on something you cannot hear directly; the indirect effect of modulat-
ing the woofer’s output with non-musical, sub-20 Hz information can
only be deleterious to the performance of the system.
R Load refers to the resistive load the phono preamplifier presents to
the cartridge. (Of course, any resistance in the phono cables is beyond
the preamp’s control and added to this figure.) This number is nor-
mally 47000Ω for moving magnet (MM) cartridges, and can range
from about 3Ω to 47kΩ for moving coils (MC).
Specifically, we include precision resistor values of 3.3, 5.0, 7.7, 10, 33,
50, 77, 100, 330, and 47kΩ, plus a set of terminals that may be used for
accessing some “other,” custom value of your choice. You would do so
by placing a precision resistor across these terminals located inside each
of the phono modules, tightening the screws down, and then selecting
other in the R Load menu item.
The best choice for resistive loading is whatever sounds the best with
your MC cartridge—you cannot damage a cartridge by playing at the
“wrong” resistance. With the Nº32, for the first time, you can make this
determination in real time, from your listening position, using the re-
mote control to access this menu item.
C Load refers to the capacitive load the phono preamplifier presents to
the cartridge. (Of course, any capacitance in the phono cables is be-
yond the preamp’s control and should be added to this figure.) This
number is normally 0.01µF for moving coil (MC) cartridges, and can
range from about 0pF to 350pF for moving magnets (MM).
Specifically, we include precision capacitor values of 0, 50, 100, 150,
200, 250, 300, 350pF, plus 0.01 µF.
The best choice for capacitive loading is whatever sounds the best with
your MM cartridge—you cannot damage a cartridge by playing at the
“wrong” capacitance. With the Nº32, for the first time, you can make
this determination in real time, from your listening position, using the
remote control to access this menu item.
