sensitivity
(Sensitivity)
The outer rotary switches are used to set the desired input sensitivity for
the left and right channels as shown in Table 3. The input sensitivity can
be adjusted in 8 steps with and 8 steps without subsonic filter. The
information about the requirements of your cartridge will be included in
the
manufacturer’s specification for the pick-up system you intend to use.
Select the value which
is closest to the manufacturer’s stated figure. If
you do not have access to the
manufacturer’s specification, a good
starting point for sensitivity is position 4 (330 - 460 mV). This is the
factory default setting.

It is essential to set the same value for both channels.

The subsonic filter attenuated rumble and low frequency noise below the
hearing band. This helps to avoid excessive excursions of the woofers.
To switch on the subsonic filter, please select one of the input
sensitivities (1...8) in the region marked 'SUBS ON'.
