2. Cartridge Type
You can choose between Moving Coil Phono Cartridges (MC) or Moving Magnet Phono Cartridges (MM).
You can choose MM setting for some MC (or other type) high output cartridges as well.
When MC setting is selected, a low noise solid state stage take care of the low level MC signal before the
tube and equaliser stages. When MM setting is selected this stage is totally bypassed.
3. Capacitance
For the MM cartridges, you can choose the desirable Input Capacitance. Try values near cartridge
manufacturer
’s recommended value to ‘’flatten’’ the response and avoid resonant peaks in higher
frequencies. However, the capacitance values are affected from the
cartridge’s design philosophy, as well
as from the connecting cables, so there is no absolutely correct setting. Therefore, experimentation is
recommended until you find a setting that suits your set-up and personal preference.
For the MC Cartridges, the setting is always suggested to be at the lower value.
4. Impedance
You can choose the desirable Input Impedance for the MM or MC cartridges. Try values near cartridge
manufacturer
’s recommended value to ‘’flatten’’ the response. However, the impedance values are affected
from the
cartridge’s design philosophy, so there is no absolutely correct setting, and experimentation is
recommended until you find a setting that suits your set-up and personal preference. As a general rule the
higher value that you load your cartridge, gives you higher response on high frequencies.
User Notes
Melto1 phono stage is perfectly designed to minimize hum and let the lowest possible noise with maximum
signal headroom. You can use any type of turntable or cartridge with this phono stage. Melto1 allows the
user to optimize the phono stage to the many different cartridges available. It is important to always ground
your tonearm on the grounding sockets of melto1.
