Level matching
To compensate the various level differences between all your audio sources, “The Grail” gives
you the possibility to change the amplification factor.
This amplification factor variation is also meaningful, if you use a quite “super-low”output
voltage MC cartridge, or your high output voltage MC system is just at the “low side” of it's
kind and you would like to use it at the MM input of “The Grail”.
Also conceivable: your complete audio chain has a quite low amplification factor and you use
speakers with low sensivity.
In all this cases it is meaningful to adjust the amplification factor of your phonograph
preamplifier.
With “The Grail” this is easy done. Simply remove the four Allen key screws of it's top plate.
Remove the top plate and take a look inside of the preamplifier: you will find 2 small switches,
in form of a single DIP-switch, one for each channel. Please take a look at the pictures below,
they explain the procedure (color of the switch may be red or blue in your amplifier).
Simply choose the desired amplification factor by pushing the respecting levers to the “on”
position.
Basically: the higher the “dB” figure, the higher the amplification factor and as a result the
louder the music signals will be.
In general: always set switches equal on both channels
