POWER

Plug one end of the supplied AC cord into the standard IEC power connector on the Sub Phatty’s left-

side panel. Plug the other end into an AC outlet. The Sub Phatty’s universal power supply will operate

with 50 or 60Hz AC power sources ranging from 100 to 240 volts. Flip on the power switch located

next to the power connector.

NOTE: It may take as long as 60 seconds for the Sub Phatty to warm up before oscillator tuning has

stabilized if you’ve left it outside on a cold night. (Although its oscillators are surprisingly stable, the Sub

Phatty is an analog synthesizer, after all.)

AUDIO OUT

With the MASTER VOLUME turned all the way down, plug one end of a 1/4 inch instrument cable into

the Sub Phatty’s unbalanced AUDIO OUT jack and the other end into an ampliﬁed speaker or mixing

console input. Adjust the level by slowly turning the MASTER VOLUME knob clockwise while playing

the keyboard.

If you’ll be using headphones, plug them into the headphones jack (on the front panel’s bottom-right

corner) with HEADPHONE VOLUME turned all the way down. Adjust the level by slowly turning the

HEADPHONE VOLUME knob clockwise while playing the keyboard. Note that MASTER VOLUME must

be turned up as well.

EXTERNAL AUDIO IN

Located just above the AUDIO OUT jack, the jack labeled EXT IN allows the Sub Phatty to shape and

ﬁlter external sounds. This is an unbalanced input that accepts a line-level signal. You can adjust the

audio level using Shift mode (see page. 25) or the plug-in editor.

NOTE: You must press a key to pass external audio through the Sub Phatty. You also can use a Moog

FS-1 footswitch, or any 1/4” cable to open the gate. Simply connect to the 1/4” Gate jack.

USB

To use the Sub Phatty with a computer, connect one end of a USB cable to the Sub Phatty’s USB port

and the other end to an available USB port on your computer. The Sub Phatty supports MIDI I/O over

USB, but not audio data.

MIDI

Using the Sub Phatty with an external MIDI device requires one or two MIDI cables. To use the Sub

Phatty as a MIDI controller, connect one end of a MIDI cable to the Sub Phatty’s MIDI OUT jack and the

other end to another device’s MIDI IN jack.

To control the Sub Phatty from an external MIDI controller, connect one end of a MIDI cable to the Sub

Phatty’s MIDI IN jack and the other end to an external controller’s MIDI OUT jack. By default, the Sub

Phatty is set to transmit and receive MIDI data on MIDI Channel 1.

CONTROL VOLTAGE IN

The PITCH CV, FILTER CV, and VOL CV inputs each accepts an expression pedal (such as the Moog

EP-2) or a control voltage signal from 0 to +5 volts. If you connect an expression pedal to VOL CV,

you can use your foot to control the Sub Phatty’s output level. If you connect an expression pedal to

FILTER CV, you can sweep the ﬁlter cutoff in the same manner. The PITCH CV and FILTER CV inputs

are calibrated so that a one-volt change in the control voltage will result in a one-octave change in

frequency.

The KB GATE input accepts a +5 volt signal, which causes the Sub Phatty’s envelopes to trigger.
