USB

The Deluge’s USB type-B connection enables several functions. This can be used as a connection to your computer as a USB MIDI device, for use in any software that supports MIDI. The Deluge may also be powered by its USB connection - either from a computer, or from a USB wall adaptor with an appropriate cable. The Deluge may draw up to 500mA from its power source. Deluge also can be used as a USB Host. This requires Deluge to be DC powered, a USB device connected and then Deluge to be powered up.

DC Power Socket (9 - 12V)

The Deluge may be powered by any centre-negative 9 - 12V DC power supply which can provide at least 500mA. It can be a shared power supply with other units in a typical daisy chained pedal configuration only if the power supply can provide adequate current. The Deluge contains circuitry to minimise ground loop noise in such a setup, although some noise may still be introduced. DC and USB power may be connected simultaneously, in which case the Deluge will draw its power from the DC power supply rather than USB.

It is important to remember that the 9 - 12V DC power supply must be centre-negative, not centre-positive. Using the incorrect power supply may cause damage to the Deluge.

Battery

The Deluge has an internal Li-ion battery, providing 6+ hours of life. The battery charges any time a power source is connected to the USB or DC power socket, regardless of whether the Deluge is switched on. The battery status LED illuminates yellow for charging, green for charge-complete, or red for low-battery.

The Deluge’s battery is an “18650” 3.7V Li-ion, and may be replaced by the user. These batteries are readily available from stores everywhere. A “protected” or “unprotected” type may be used. A battery of any mAh rating may be used - higher mAh ratings simply mean longer battery life.

Please note that your Deluge will be shipped with very little charge in the battery. You will need to plug it into a power source to use it and begin charging the battery.

SD card slot

The Deluge uses SD (or SDHC) card storage to load and record audio samples, store presets and save songs. Typically a 16GB or 32GB is recommended, but any size can be used, formatted to FAT32. The Deluge’s firmware can also be updated via the SD card.

L / MONO and R outputs

The Deluge’s main audio outputs are two quasi-balanced (that is, resistor-balanced but not differential) 1/4” connectors. They will work with non-balanced cables too. For best noise rejection, use balanced cables when connecting the Deluge’s outputs to balanced / differential inputs. Output impedance: 47 ohms.

Deluge will detect if only the “L / MONO” output has a cable inserted (but not the “R” output or headphone output), and will output all sound in mono. In this case all panning and ping-pong delay will be deactivated, and stereo samples will be condensed to mono. This allows you to work on your music on a stereo setup, but not necessarily need to change anything if you are faced with a mono setup.

Headphone output

This can drive headphones, or can be used to connect other equipment with a 3.5mm / 1/8” connector - perhaps computer speakers or a car stereo.

Line input

For recording from another device’s line output. The line input uses TRS 1/4” / 6.35mm connector, which may accept a single-ended / unbalanced signal, a differential / balanced signal, or a stereo signal. Input impedance: 4k.

Mic input

For recording with an external microphone use the 3.5mm / 1/8” jack. Gain is set via the “mic gain” switch, which also affects the internal microphone. Stereo and mono microphones are supported. 4.5V plug-in power is supplied on the tip and ring of the connector, each through a 3.9k resistor.

CV, gate, and trigger clock (“CLK IN”) connectors

These all have the signal on their “tip”, ground on their “sleeve”, and their “ring” connected to ground via a 10k resistor.
