phono gain
Th e phono gain menu is only active if the optional phono module is installed;
otherwise it is grayed out. When it is installed, the CP-500 will automatically
recognize it, rename the line 1 input to phono, and activate the input on the
main menu.
Setting the phono gain is simple enough: choose low gain for most moving
magnet cartridges, and for high output moving coil cartridges; choose high
gain for low output moving coil cartridges. Your Classé dealer can assist you
in determining what type of cartridge you have, and which setting is most
appropriate.
triggers Each of the CP-500’s trigger outputs may be programmed as to its “logic level,”
which is to say, whether its voltage is low (essentially 0V), or high (approximately
12V) when the trigger is activated. Th
e ability to change the logic level of a
trigger’s “on” state can solve installation-specifi c problems that otherwise require
external devices that add to both the cost and complexity of your system.
If this seems an obscure point, that’s okay. It is a feature designed to solve
problems you may not even have, but your installation professional appreciates
being able to easily solve such problems when they occur.
max volume
Th e max volume screen allows you to establish a maximum volume setting for
your system. Th is scale runs from 0 to 100, with 100 indicating that you do
not want any artifi cial limit placed on the maximum gain your preamplifi er can
provide.
Th is setting is interactive. You can set the value to something less than 100, and
then adjust the volume to see whether it is appropriate.
