GND
Low Pass Filter: This control determines the upper end of the
frequency range reproduced by the Temblor T10. If you have
enabled the onboard highpass filter, set the Low Pass Filter
control to the same value. Otherwise, set the Low Pass Filter
control to the lowest frequency that your main studio monitors
can reliably reproduce. Note that this control only affects the
signal going to the internal amplifier and the Sub Out output
and does not affect the main outputs. If you daisy-chain two
T10s, set the second one's lowpass filter to its highest setting,
130 Hz, to make sure it reproduces everything it gets
from the first T10.
Ground Lift Switch: In the "Lift" position, this switch adds 1 kΩ
resistance to the ground for the balanced inputs. The Ground
Lift switch doesn't affect the AC mains safety ground for the
power supply.
Power User Tip: Enabling the ground lift can help to reduce
ground loop noise in your audio system. Ground loops can be
caused by running audio cables with power cables, by older
buildings with improper wiring, or by equipment that generates a
lot of RFI, such as computers, laptop power supplies, and the like.
