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.
