Control functions:
Input Selector Switch:
Selects between line level input (phono connector) and
high level input (jack socket). Both inputs may be
connected at the same time. Only the selected input will
be passed through the DSP circuit.
Filter Level Selector Switch:
The 8 position rotary switch selects the amount of DSP
processing. Level 0 is the minimum, and level 7 the
maximum. The selected level can be seen in the small
cutout in the switch knob.
Noise Cancellation LED:
Indicates if noise cancellation is on/off.
Noise Cancellation On/Off Switch:
Selects noise cancellation on/off.

Sets the input level into the NEIM1031. This adjusts the
audio signal level through the DSP for optimum
performance.

These give a visual indication of the input signal level.
No LED:
Signal level too low
Green LED:
Signal level correct
Red LED:
