CONNECTIONS

We usually recommend that this pedal be placed at the end of your chain, after
other effects. If you are using the overdrive channel of your amplifier, this effect
should be placed in the effects loop for best results.

The POWER JACK accepts a standard (5.5 mm OD x 2.1 mm ID) center-negative
pedal power adapter (not included). The power adapter must be between 9 V and
12 V and capable of supplying 100 mA or more.

The INPUT JACKS (right side) accept inputs directly from your instrument,
amplifier eects loop output, or other eect pedals via standard 1/4” (6.35 mm)
phone connectors.

• Input 1 only accepts a mono input.

• Both Inputs 1 & 2 accept a stereo input.

• Input 2 only accepts a stereo TRS input.

The OUTPUT JACKS (left side) supply output to another eect pedal, an amplifier,
or eects loop return via standard 1/4” (6.35 mm) phone connectors. The buered
output is capable of driving long cables. If plugging into the input of an amp, you
should use the low impedance (Lo-Z) input if available.

• Output 1 only supplies a summed mono output.

• Both Outputs 1 & 2 supply a stereo output. Using both outputs creates a
stereo signal from a mono input.

• Output 2 only supplies a stereo TRS output.

The input and output connections are independent. You may—for example—use a
mono input with stereo outputs or stereo inputs with a stereo TRS output.

Important! Input/output 1 and input/output 2 should not be used with two discrete
signals (such as two different instruments).

The USB JACK allows you to plug the pedal into your Mac or PC using a standard
micro-B cable and change the effect using Expanse software, available at
neunaber.net (see the Configuration section for details).

The ExP PORT connects to an (optional) ExP controller.

The FOOT SWITCH bypasses the eect. The LED lights when the eect is active.
Bypassing the eect does not lower power consumption, because it does not turn
o power to the pedal.

Pedals have three selectable bypass options: (1) buered trails, (2) true bypass and
(3) two-stage trails/true bypass.

When using buered bypass, the signal is always buered whether the LED is on
or o. Trails bypass is implemented for those eects that support it (reverb and
echo).

Note: A knob change cannot be detected when the pedal is o. When the pedal
is powered on, it will revert to the stored state of the knob. When in doubt, turn the
knob, and it will “snap” to the current setting.

CONFIGURATION

Programming an Expanse pedal is a two-step process:

1. Load a dierent eect using Expanse software, downloadable from neunaber.net.

2. Configure the Mix Knob & Switch Behavior on the pedal itself.

These two steps are independent. For example, loading an echo eect does
not automatically enable the tap tempo functionality. This must be enabled by
configuring the Second Switch Function.

MIX KNOB & SWITCH BEHAVIOR

Dry Signal Mix, Bypass Mode, and Second Switch Function are configured on the
pedal itself and can be dierent for each eect (if you have an ExP).

DRY SIGNAL MIX - is how the Mix knob aects the dry signal. Generally, the level
increases as you turn the knob up, but there are dierent strategies and some
work better than others depending on the eect:

• Steep End Drop— The dry signal is constant until 50% Mix, then gradually

lowers until about 3 o’clock where it drops o steeply. At 100% Mix, the dry
signal is muted. This works well for reverb and echo.

• Unity Power Sum— The dry signal is lowered gradually (-3 dB at 50% Mix),
which results in a constant power sum with wet signals and an even mix at 12
o’clock. This works well for chorus.

• Unity Dry Signal— The dry signal remains constant throughout the Mix knob’s

range. This works well if you don’t want 100% wet signal. The total signal level
will increase by up to 3 dB with the knob at full.

• Split Wet/Dry— A special mode reserved for wet/dry setups.

5

BYPASS MODE - Selects the type of bypass:

• Buered— For trails bypass, select this option.

• Relay— true bypass

• 2-Stage— switches to a buered trails bypass while the footswitch is held down,

then to true bypass when released. This option allows for both trails and true
bypass, where you control the length of the trail.

Important! Buered bypass must be selected for the Infinity Hold eect.

SECOND SWITCH FUNCTION - Selects a second function for the footswitch,
which is particularly useful for certain eects like echo and shimmer:

• None— no second function

• Tap Tempo with Bypass Priority— bypass is always toggled, tap tempo is set if

footswitch pressed again within 1 second

• Tap Tempo with Tap Priority— bypass is toggled only when the footswitch is not

pressed again within 1 second. This results in a 1 second delay when bypassing
but avoids toggling bypass when setting tap tempo.

• Long Press Enables Right Knob— pressing the footswitch for greater than ½

second enables/disables the right-hand knob. “Disabling” the knob is equivalent
to turning it fully counter-clockwise.
