EarthQuaker Devices Grand Orbiter OPERATION MANUAL

The Grand Orbiter™ is a 4 stage OTA-based phaser with a diverse feature set that can go from stationary and resonant to slow and mellow and on through fast and swirly. It has three way toggle switch to select between the ranges of modulation: Rate 1 is slow sweep mode, Rate 2 kills the LFO and allows

you to use the Grand Orbiter as a xed resonant lter and Rate 3 is fast sweep mode. The master Rate control ne tunes the speed of the LFO in each of these modes and the ashing red LED acts as a

visual indicator, even when the effect is in bypass

mode. The Depth control blends the shifted signal

in with the dry signal and controls the intensity of the effect. The Sweep control governs the peak frequency of the phased signal’s tone, turned full clockwise the sweep is lively and intense, whereas turning counter clockwise yields a darker, more laid back peak. The Resonance provides a wide range of control over regeneration and at higher settings adds a more pronounced and resonant tone. You can also use the Grand Orbiter as a true pitch vibrato with the “Phase/Vibrato” switch. When in “Vibrato” mode, the dry signal is removed and the

Depth controls acts as a volume control. This pedal

is 100% analog, true bypass and built by entirely by hand in beachy Akron, Ohio.

Controls

Depth: Controls the amount of phase effect

mixed with dry signal. Clockwise for more

intense phasing, counterclockwise for less. In “Vibrato” mode, this acts as a volume control.

Rate: Controls the speed of the LFO. Faster clockwise, slower counter clockwise.

Phase/Vibrato: Cuts the dry signal to create a vibe/vibrato effect depending on the setting of the other controls. Vibrato is created by turning the resonance down low.

Flexi-Switching

This device features Flexi-Switch

This relay-based, true bypass switching style allows you to simultaneously use momentary and latching style switching.

• For standard latching operation, tap the footswitch once to activate the effect and then tap again to bypass.

• For momentary operation, hold the footswitch down for as long as you’d like to use the effect. Once you release the switch the effect will be bypassed.

Since the switching is relay based, it requires power to pass signal.

Technology!

Power

The Grand Orbiter can be powered by a standard

9-volt DC power supply with a 2.1mm negative

center barrel. We always recommend pedal-

specic, transformer-isolated wall-wart power

supplies or multiple isolated-output supplies.

Pedals will make extra noise if there is ripple or

unclean power. Switching-type power supplies,

daisy chains and non-pedal specic power supplies do not lter dirty power as well and let through unwanted noise. Do not run at higher

voltages!

Sweep: Controls the frequency peak of the sweep. Higher peak clockwise, lower peak counter clockwise.

Resonance: Controls the regeneration of the phased signal. More resonant clockwise, more subtle counter clockwise.

Rate 1,2,3: Changes the range of the speed control. Rate 1 is slow mode, rate 2 is LFO kill

to use the Orbiter as a xed resonant lter, rate 3 is fast mode.

Current Draw: 45mA

Input impedance: 1M

Output impedance: <1K
