11.2.2. Subsonic filter
Warped records and unfavorable pickup cartridge/pickup arm combinations can cause major low-
frequency interference that impairs bass reproduction. These low-frequency levels can be attenuated
with the switchable subsonic filter. The corner frequency is outside of the audible range at 15 Hz.
Condition on delivery: Subsonic filter on.
Phono frequency response with and without subsonic filter
The frequency range without subsonic filter is very linear and extremely low (red graph). With the
subsonic filter (cyan graph), bass reproduction is not limited by the low corner frequency (-3 dB at
15 Hz).
