INTRODUCTION
The Immerse Mk II represents the very best in pedal reverberation — with studio-
quality algorithms, high-fidelity circuitry, heavy-duty components and construction
— all in a small footprint. The Mk II is a monumental step forward and features
completely-redesigned circuitry and upgraded algorithms:
• Mix adjustable from 100% dry to 100% wet
• Increased headroom
• New W3T reverb algorithm
• New Sustain eect
• Various improvements to most eects
• Easier-to-read graphic layout
The Mk II implements a high-quality buered bypass. The signal is always buered
whether engaged 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.

Q: Where do you place this eect? A: Reverb sounds best at the end of the chain.
EFFECTS LOOP
Using the drive channel of your amp? Connect reverb in the eects loop.
Note: Enable kill dry for parallel FX loops only.

CONNECTIONS
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 80 mA or more.
The Input Jacks accept inputs directly from your instrument, amplifier eects
loop send, or other eect pedals via standard 1/4” (6.35 mm) phone connectors.
Inputs 1 and 2 should not be used with two discrete signals, such as two dierent
instruments.
The Output Jacks supply output to another eect pedal, an amplifier, or eects
loop return via standard 1/4” (6.35 mm) phone connectors. The output is buered
and capable of driving long cables.
SWITCHES
The Footswitch engages the eect, and the LED lights when the eect is active.
There are two mini-switches next to the Power jack:
• Kill Dry removes the dry signal, even when bypassed. This should be enabled
for parallel eect loops and disabled for serial (common) eect loops.
• Trails allows the eect to naturally trail 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.

W3T™ Version 3 of the WET algorithm — our flagship reverb. Smoother
decay and more three-dimensional sounding, it enhances what
you play without covering it. Adjustable pre-delay further
separates the dry signal and reverb up to an additional 200
milliseconds (ms).
Plate A physical plate reverb uses transducers mounted to a large,
suspended metal plate. It is known for its bright, diused sound.
Adjustable pre-delay further separates the dry signal and reverb
up to an additional 200 ms.
Hall Hall reverb simulates the sound of a well-designed concert hall.
The Mod knob controls the modulation depth — try increasing it
for a lush, modulated hall reverb.
Spring A physical spring reverb uses metal springs suspended between
transducers and produces a distinctive “twerp.” The Mod knob
increases the modulation rate — try increasing the modulation
rate for a classic vibrato-spring reverb sound.
EFFECTS

EFFECTS
Sustain Built on our W3T reverb, Sustain is a magical eect that can be
configured as a sustain eect or virtually infinite reverb. What you
play is recycled in an infinite loop during a ”hold” phase, then
decays out during a “release” phase. The Time knob adjusts the
hold time, while the Depth knob adjusts the release. The Mod
knob controls the modulation depth.
Echo This eect adds echo and reverb. The Time knob adjusts the
echo time, from 50 to 700 ms. Depth controls both the reverb
decay and echo repeats. Blend controls the mix between the
reverb and echo eects.
↓tune Detune is a an eect that pitch-transposes a signal slightly
downward. This eect adds detune to a detuned reverb to
produce a thick, chorus-like eect. The Blend knob controls the
mix between the reverb and detune eects.
Shim Shimmer is a reverb eect reminiscent of a synth pad that follows
what your instrument plays. The Blend knob controls the mix
between the reverb and shimmer eects.

CONTROLS
Mix The Mix knob adjusts the blend of dry (unaected) signal to
eect and ranges from 100% dry to 100% eect.
Eect The center knob selects the reverb eect. The knobs below
may change function depending on the selected eect.
Depth The Depth knob controls the reverb depth (also called decay
time). When the Echo eect is selected, it also controls the
number of repeats (regeneration).
Time
Tone
This knob adjusts the eect tone except as follows:
• Sustain, knob controls Hold time
• Echo, knob controls the Delay time

Mod
Blend
This knob controls the reverb-to-eect blend except as follows:
• W3T and Plate, knob controls pre-delay
• Hall and Sustain, knob controls modulation depth
• Spring, knob controls modulation rate
