b. Input sensitivity (Gain)
It is important to match the input sensitivity of the
Phono equaliser
to the output value of the cartridge
in use. Only this will ensure the maximum S/N ratio
and will prevent distortion.
The Gain has three settings:
-
High:
for cartridges with an output signal
between 250 µV and 750 µV.
-
Mid:
for cartridges with an output signal
between 750 µV and 1,5 mV.
-
Low:
for cartridges with an output signal
between 1,5 mV and 15 mV.
The Gain is set with switches 1 and 2 of the large
red ‘switch blocks’ (one for each channel).
Using the value of your cartridge (as marked in the
table), move the switches to the correct value
according to one of the following pictures.
c. Input capacity (MM)
This setting is specifically for MM cartridges. The
standard value is 47-pF, but some cartridges need a
value of 147-pF for optimum results.
Note
: This setting has no influence on the MC
settings.
The standard value is ‘LOW’ (47-pF).
You select the HIGH value by moving switch 3 to the
upper (ON) position.
