PEDAL MAP

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.
CONNECTIONS
We recommend that this pedal be placed at the end of your chain, after all other
eects. If you are using the overdrive channel of your amplifier, this eect should
be placed in the eects 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 70 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.

Important Note: input/output 1 and input/output 2 should not be used with two
discrete signals (such as two dierent instruments).
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.
The Immerse Reverberator implements a high-quality buered bypass. The signal
is always buered whether on or bypassed. We chose this type of bypass because
the last output in a pedal chain should be buered, and reverb is typically placed
at the end of a pedal chain.
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 KILL DRY switch removes the dry signal, leaving only the “wet” (eect) signal.
This should be enabled for parallel eect loops, and disabled for serial (common)
eect loops.
The TRAILS switch changes the bypass mode between normal and trails. Trails
allows the eect to naturally trail o after the pedal is bypassed. With normal
bypassing, the eect is abruptly cut o; however, normal bypassing results in
lower noise while the pedal is bypassed.
EFFECTS
Reverberation (“reverb”) gives your instrument a sense of acoustic spaciousness.
There have been various methods of simulating this eect over the years, several
of which have evolved into their own distinct sounds.

WET™
WET™ is an updated version of Neunaber’s renowned algorithm, with shorter
pre-delay, higher initial density and more balanced imaging. (See suggested
settings below.)

HALL
Hall reverb is known for its large, open sound—similar to what one may find in a
well-designed concert hall.
PLATE
A physical plate reverb uses transducers mounted to a large, suspended metal
plate. It is known for its bright, diused sound.

+ECHO
The +echo eect combines the Wet™ Reverb with an echo eect.
+DETUNE
The +detune eect combines the Wet™ Reverb with detune, which is a
chorusing-like eect that adds in a slightly detuned double of the dry signal.
