USER INTERFACE
1. Effect Type Selector Switch
Selects between the chorus or flanger effect.
2. DC Power Jack
Connect the specified Harman power supply (sold separately) to this jack. Be sure to use the proper
power supply for your area’s mains line voltage. See 'Specifications' on page 9 for power supply
model information. The Nautila can only be powered using the external power supply.
3. Drift Knob
Varies the shape of the modulation sweep. This is a continuously variable, 360° control which
allows for morphing between triangle, log/asymmetrical, and sine wave shapes.
4. Emphasis Knob
This knob works differently depending on whether the chorus or flanger effect is selected. When
chorus is selected, this knob provides a tone control for the chorus effect signal. Turning the knob
up past the 12 o'clock position will enhance high frequencies in the effect signal, and turning the
knob below the 12 o'clock position will reduce high frequencies in the effect signal. When flanger
is selected, this knob will control the regeneration (the amount of effect signal fed back into itself),
which dramatically enhances the flanger’s harmonics during its sweep.
5. Voices Knob
Selects the number of effect voices. At the minimum position a single voice is used. The maximum
position provides 4 voices for the flanger effect or 8 voices for the chorus.
