Start by selecting the nearest lower value of gain for the desired cartridge. As gain settings are applied directly
(after a 10 second mute), one may also set the gain (by ear), to offer a similar loudness as a line level source. Once
the selection has been made, press the
button on the front panel (F3) or on the remote control (RC6) to confirm
the selection and continue to the next item.
4.4 Individual EQ Settings
The 2
nd
line of the display depicts the EQ selected.
Use the front panel
/
buttons (F2) or on the remote control (RC7) to adjust the EQ curve that is used when
this input/cartridge is selected. This is very useful if a cartridge is dedicated to playing only certain types of records
such as a Mono cartridge for Mono LP’s. Changes to the EQ curve happen in real-time with a brief mute.
Once the desired selection has been made, press the front panel
button (F3) or on the remote control (RC6) to
confirm and continue to the next item.
When the specific EQ curve has been selected, whenever that particular input is used, the PH-77 will always start
with the user-selected curve. It will automatically cycle through only the respective Stereo or Mono curves.
