The 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.

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. The ability to change the logic level of a trigger’s “on” state can solve installation-specific 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.

The max volume screen allows you to establish a maximum volume setting for your system. This scale runs from 0 to 100, with 100 indicating that you do not want any artificial limit placed on the maximum gain your preamplifier can provide.

This setting is interactive. You can set the value to something less than 100, and then adjust the volume to see whether it is appropriate.
