AC-22LX Eect Parameter List
CHORUS
Chorus is an eect that creates a beautiful tonal spaciousness and depth
by adding a slightly modulated sound.
Type Explanation
MONO This chorus eect outputs the same sound from both the L and R
channels.
STEREO 1
This stereo chorus uses spatial synthesis, with the direct sound
output to the L channel and the eect sound output to the R
channel.
STEREO 2 This is a two-phase stereo chorus eect that adds dierent chorus
sounds to the L and R channels.
2x2 CHORUS
The frequency bands are divided to produce two dierent choruses,
one for low frequencies and one for higher frequencies. This makes
the chorus sound more natural.
MONO, STEREO 1, STEREO 2 parameters
Parameter Value Explanation
RATE 0–100 Adjusts the rate of the chorus eect.
DEPTH 0–100 Adjusts the depth of the chorus eect.
PRE DELAY 0.0–10ms
Adjusts the time needed for the eect sound
to be output after the direct sound has been
output.
WAVE FORM
SIN
Produces a deeper sense of modulation.
TRI
Produces a typical chorus eect.
LOW CUT FLAT, 20.0Hz–
20.0kHz
Sets the frequency at which the low cut lter
begins to take eect. When “FLAT” is selected,
the low cut lter has no eect.
HIGH CUT 20.0Hz–
20.0kHz, FLAT
Sets the frequency at which the high cut lter
begins to take eect. When “FLAT” is selected,
the high cut lter has no eect.
EFFECT LEVEL 0–100 Adjusts the volume of the eect sound.
DIRECT MIX 0–100 Adjusts the volume of the direct sound.
Setting this to 0 cuts the direct sound.
2x2 CHORUS parameters
Parameter Value Explanation
LOW RATE 0–100 Adjusts the speed of the chorus eect for the
low frequency range.
LOW DEPTH 0–100
Adjusts the depth of the chorus eect for the
low frequency range. To use this as a doubling
eect, set this to “0”.
LOW PRE DELAY 0.0–40.0ms
Adjusts the delay of the eect sound in the
low-frequency range. Extend the pre-delay
to produce the sensation of multiple sounds
(doubling eect).
LOW LEVEL 0–100 Adjusts the volume of the chorus sound in
the low-frequency range.
XOVER FREQ 100Hz–
4.00kHz
This sets the frequency dividing the low- and
high-frequency ranges.
DIRECT MIX 0–100 Adjusts the volume of the direct sound.
HIGH RATE 0–100 Adjusts the speed of the chorus eect for the
high frequency range.
HIGH DEPTH 0–100
Adjusts the depth of the chorus eect for
the high frequency range. To use this as a
doubling eect, set this to “0”.
HIGH PRE DELAY 0.0–40.0ms
Adjusts the delay of the eect sound in the
high-frequency range. Extend the pre-delay
to produce the sensation of multiple sounds
(doubling eect).
HIGH LEVEL 0–100 Adjusts the volume of the chorus sound in
the high-frequency range.
REVERB
This eect adds reverberation to the sound.
Type Explanation
PLATE
Simulates plate reverberation (a reverb unit that uses the vibration
of a metallic plate). Provides a metallic sound with a distinct upper
range.
ROOM Simulates the reverberation in a small room. Provides warm
reverberations.
HALL Simulates the reverberation in a concert hall. Provides clear and
spacious reverberations.
MODULATE This reverb adds the wavering sound found in hall reverb to provide
an extremely pleasant reverb sound.
REVERB parameters
Parameter Value Explanation
REVERB TIME 0.1–10.0s Adjusts the length (time) of reverberation.
PRE DELAY 0–500ms Adjusts the time until the reverb sound
starts to output.
LOW CUT FLAT,
20Hz–800Hz
Sets the frequency at which the low cut
lter begins to take eect. When “FLAT” is
selected, the low cut lter has no eect.
HIGH CUT 630Hz–12.5kHz,
FLAT
Sets the frequency at which the high cut
lter begins to take eect. When “FLAT” is
selected, the high cut lter has no eect.
DENSITY 0–10 Adjusts the density of the reverb sound.
EFFECT LEVEL
GUITAR/INST 0–100 Adjusts the volume of the reverb sound for
GUITAR/INSTRUMENT.
EFFECT LEVEL MIC 0–100 Adjusts the volume of the reverb sound
for MIC.
NS (NOISE SUPPRESSOR)
This eect reduces the noise and hum picked up by acoustic instrument’s
pickups or a microphone. Since it suppresses the noise in synchronization
with the envelope of the sound (the way in which the sound decays over
time), it has very little eect on the sound of the acoustic instrument or
the microphone, and does not harm the natural character of the sound.
Parameter Value Explanation
GUITAR/
INSTRUMENT OFF, ON Turns NS for GUITAR INSTRUMENT on/o.
MIC OFF, ON Turns NS for MIC on/o.
THRESHOLD 0–100
Adjust this parameter as appropriate for the
volume of the noise. If the noise level is high, a
higher setting is appropriate. If the noise level is
low, a lower setting is appropriate.
* High settings for the threshold parameter may
result in no sound when you play with your
instrument’s volume turned down.
RELEASE 0–100 Adjusts the time from when the noise suppressor
begins to function until the noise level reaches “0”.
FOOT VOLUME
This is a volume control eect.
Parameter Value Explanation
SIGNAL
ASSIGN
GTR/INST, MIC,
MASTER Selects the signal to be controlled.
VOLUME MIN 0–100 Sets the volume when the heel of the EXP Pedal
is depressed.
VOLUME MAX 0–100 Sets the volume when the toe of the EXP Pedal
is depressed.
LEVEL 0–100 Sets the volume.
* Use the EV-1-WL (sold separately) to control the LEVEL.

EV-1-WL Connection Guide
This guide explains how you can use BLE MIDI to wirelessly pair (connect) the EV-1-WL and AC-22LX.
* The Bluetooth Audio MIDI Dual Adaptor (Model: BT-DUAL, sold separately) is needed when wirelessly pairing the EV-1-WL with the AC-22LX.
See the Owner’s Manual for how to attach the adaptor.
What is “BLE MIDI”?
“BLE MIDI” is the technology used to transmit and receive MIDI
messages wirelessly via Bluetooth® LE.
This is ocially known as “MIDI over Bluetooth Low Energy”.
Connecting the AC-22LX, EV-1-WL and
AC-22LX Editor at the Same Time
Connect the units in the order shown below.
Connection 1: Connect the AC-22LX and the EV-1-WL

Connection 1: Connect the AC-22LX and the EV-1-WL
1. Turn the AC-22LX on.
The Bluetooth indicator on the BT-DUAL blinks. If the indicator is
unlit, press the BT-DUAL pairing button to make it blink.
2. With the EV-1-WL turned on, place it nearby.
3. Make sure that the Bluetooth indicator on the EV-1-WL is
blinking white.
If the indicator is blinking blue or is lit up white, operate the device
as shown below to make the indicator blink white.
Blink blue Quickly press the EV-1-WL’s [Bluetooth] button twice.
Lit white
The device is connected to a dierent device (product).
Long-press the [Bluetooth] button on the EV-1-WL to
disconnect the unit from that device (product).
4. Press the EV-1-WL’s [Bluetooth] button.
The Bluetooth indicator on the EV-1-WL rapidly blinks white, and
pairing begins.
The Bluetooth indicator on the EV-1-WL stops blinking and remains
lit white when pairing is nished, and the AC-22LX and EV-1-WL are
now connected.
When the devices are correctly connected, their respective statuses
are as follows.
BT-DUAL Bluetooth indicator Lit blue
EV-1-WL Bluetooth indicator (*1) Lit white
*1 To check the indicator status, quickly press the Bluetooth button on the EV-1-WL
twice. The color switches between white (lit up) and blue (blinking).
Connection 2: Connecting the AC-22LX and AC-22LX
Editor
Connect the AC-22LX to the AC-22LX Editor. Follow the steps in “Launching
the AC-22LX Editor” (p. 1) to connect.

device after connecting to the AC-22LX, or when turning o
the power while the Bluetooth indicator is blinking white
(not connected), or when doing a factory reset of the EV-1-WL,
the device does not pair automatically. In this case, go back to
“Connection 1” to congure the settings.
¹When using Bluetooth audio from a mobile device, rst connect
the AC-22LX and the mobile device via Bluetooth audio, and then
connect the EV-1-WL to the AC-22LX.
