7.3. MM Capacitive Load
MM Cartridges often give the optimum performance when loaded with a capacitive load.
The
Evo Phono 3
allows for setting the MM input capacitance to 0pF, 100pF, 220pF or
320pF. To set the capacitance value, press the two right buttons together until the desired
value is indicated by the 2 LED’s to the upper right of the front panel.
As this setting is only relevant for MM input, these two LED’s are off when the MC input is
selected.
7.4. Subsonic filter
Warped records and turntable resonances may, under certain circumstances, drive the
power amplifier to overload, even at normal listening levels, due to low-frequency
oscillations which, while inaudible, cause the power amplifier to deliver high power to the
speakers.
In order to attenuate this phenomenon, the
Evo PHONO 3
is provided with a 16Hz high
pass filter which strongly reduces the infrasonic signal from the cartridge, while allowing
the full content of the music program to be amplified and passed to the preamplifier.
The subsonic filter can be independently set for MM and MC inputs by using the related
gain button with a long press.
