A setting of 45 dB is shown in Figure 4.
Please note that the gain settings recommended for the various cartridge outputs
will vary somewhat depending on the sensitivity of other components in your
system. These are “typical” settings and are a good starting point. If you feel like
you want a bit more or less gain try the setting above or below the value in the
table.
Bypassing the internal phono section –
If you have an external phono preamp or
you wish to bypass the internal phono so that it can be used a line level input,
simply move the two shunts from the arrow up position to the arrow left position
(see Figure 3). Please note that the direction of the shunts must follow the
direction of the arrow. If you are using an external phono or a line level device on
this input be sure to turn all the loading switches to the off position.
