First, connect it to the mixer’s AC IN connector, then
to a power outlet.
6
Turn the mixer’s LEVEL controls
(white knobs) and MASTER LEVEL
control (red knob) to the minimum
(zero). Also, set the equalizer controls
(green knobs) to the center “D” or
“MUSIC” position.
7
Set the MIC/LINE switch to the MIC (N)
position for microphone connection, and to
the LINE (O) position for connection of an
instrument or audio device.
8
Turn on the power of the connected sound
source (if applicable), then the mixer.
The POWER LED lights.
9
Set the MASTER LEVEL control to the “D” position.
10
While playing your instrument or singing into the microphone, use the
LEVEL control to adjust the volume of the corresponding channel.
11
Use the MASTER LEVEL control to adjust the overall volume.
If you hear the sound and the volume seems appropriate, setup is complete. If not,
please refer to the check list in the “Troubleshooting” section on the back of this booklet.
NOTE To avoid any loud, unexpected noise from the speaker, first turn off the power to the mixer, then the
connected sound source (such as an instrument or audio device).
Equalizer
Mixer Controls and Functions
1Mic/Line input jacks (channels 1-4)
Connect microphones, guitars, electronic musical instruments or audio equipment. Channels 3
and 4 provide combo jacks that support both XLR and phone plugs.
2MIC/LINE switches (channels 1-4)
For low-level signals (including microphones), set the switch to the MIC (N) position. For high-level signals (including electronic
instruments and audio equipment), set the switch to the LINE (O) position.
3Hi-Z switch (channel 4)
This switch is used when connecting a device directly to the mixer without a DI (direct box)—for example, instruments with passive
pickups, such as an acoustic-electric guitar or electric bass without battery. This function is effective only for the phone jack input.
4Line (stereo) input jacks (channels 5/6, 7/8)
Connect line-level devices such as electronic instruments, acoustic-electric guitars, CD
players, and portable audio players. These jacks support phone, RCA-pin, and stereo-mini
plugs.
NOTE For the channel 5/6 input, if both phone and RCA-pin jacks are used at the same time, the phone jack will take priority. For the channel
7/8 input, if both phone and stereo mini jacks are used at the same time, the stereo mini jack will take priority. The signal from the device
connected to another jack will be muted. The music signals from iPod/iPhone (9) are always mixed to channels 7/8.
XLR phone
RCA-pin stereo-mini
5MONITOR OUT jacks
These are for connection to a powered
speaker for monitoring purposes,
and output a mix of the signals from
channels 1 to 7/8. You can adjust the
output level using the MONITOR OUT
control (!). If only the L (MONO) jack
is used, the signals from the L and R
channels are mixed and output.
6|SUBWOOFER OUT jack
This is for connection to a powered
subwoofer, and outputs a mono
signal. If this jack is in use, the low
frequencies below 120Hz to the
SPEAKERS L/R jacks will be cut. The
output level is linked to that of the
MASTER LEVEL control (C).
7REVERB FOOT SW jack
This is for connection to an unlatched-
type footswitch such as the Yamaha
FC5—useful for solo performers, since
you can toggle the reverb on and off
as needed with your foot.
8SPEAKERS L/R jacks
Use the included speaker cables to
connect the dedicated speakers.
9USB connector
Connect your iPod/iPhone using a USB
cable to play music and charge the
iPod/iPhone. Use the LEVEL control
of channels 7/8 to adjust the volume,
since the music signals are mixed
to those channels. This connector
supplies 5V power to the connected
USB device. This connector does not
support digital playback from USB
devices other than the iPod/iPhone.
For playback of such devices, use
appropriate stereo mini or RCA pin
connectors.
Caution
• Use a genuine Apple Dock Connector
USB Cable for the iPod/iPhone
connection.
• Please do not use a USB hub.
NOTE If you connect an iPhone,
incoming calls or emails may
cause a notification sound to be
output. In order to prevent this, we
recommend setting the iPhone’s
Airplane mode to “on.”
DVents
These are the vents for the cooling fan
inside the mixer. Do not block the vents
when in use.
EAC IN jack
Connect the included power cord here.
F(power) switch
For turning the power of the mixer on (O) and off (N).
Caution
Rapidly turning the unit on and off in succession may
cause it to malfunction. After turning the unit off, wait for
about 5 seconds before turning it on again.
Making optimum volume settings
When the volume is too loud
Turn the LEVEL control to the minimum (zero). Set the MIC/LINE
switch to the LINE (O) position, then slowly raise the LEVEL
control until the desired volume is reached.
When the volume is too soft
Turn the LEVEL control to the minimum (zero). Set the MIC/LINE
switch to the MIC (N) position, then slowly raise the LEVEL control
until the desired volume is reached.
^ST/MONO switches (channels 5/6, 7/8)
Setting the switch to ST (STEREO) (N) will assign the signals from the L and R channels to
each left and right speaker and output each signal. Setting the switch to MONO (O) will mix
the output of different L and R sources to output the same signal to both the left and right
speakers. For keyboards with mono output, guitars, or other non-stereo sound sources,
when the switch is set to MONO, the stereo jacks can be conveniently used as multiple
mono jacks. BMASTER EQ (equalizer) control
Use this control to adjust the overall sound frequency balance. The center position “MUSIC” is a basic
setting and if you turn the control counterclockwise, this creates an optimum setting for speech, cutting
unneeded low range frequencies. If you turn the control clockwise, it creates an optimum setting for
playback of sound sources, since the low range is boosted. If you turn the control clockwise further, the
LED lights indicating that the bass boost function turns on, giving you even more powerful bass tone.
CMASTER LEVEL control
Determines the volume of the signal output from the SPEAKERS L/R jacks. This allows you to adjust the
overall volume without changing the relative volume balance among the various channels.
Applying Reverb
The STAGEPAS 400i features a built-in reverb processor that is in the same league as our famed
SPX effect processor series. This reverb lets you simulate the acoustics of different performance
environments, such as concert halls and small clubs, and add warm, natural ambience to your
vocals or instrument performance.
1
Press down the REVERB switch to turn it on.

2
Position the REVERB TYPE/TIME control to the desired
reverb type and time (length).
Turning the control toward the right lengthens the time of the selected reverb type.
3
Use the REVERB control to adjust the reverb amount of the corresponding
channel.
If necessary, repeat steps 2 and 3 to determine the optimum reverb setting.

)PHANTOM (CH1/2) switch /LED
When this switch is on, the LED lights indicating that phantom
power is available for channels 1 and 2. Turn this switch on to
supply power to condenser microphones or a DI (direct box).
Caution
Follow the important precautions below, in order to prevent
noise and possible damage to external devices and the unit
when you operate this switch.
• Be sure to leave this switch off if you do not need phantom
power, or when you connect a device that does not support
phantom power to channels 1 or 2.
• Do not connect/disconnect a cable to/from channels 1 and 2
while this switch on.
• Turn the LEVEL control of the channels 1 and 2 to the
minimum before operating this switch.
!MONITOR OUT control
Determines the signal level output from the MONITOR OUT
jacks (5). The MASTER LEVEL control does not affect the
MONITOR OUT signal.
#REVERB switch/LED
When this switch is on, the LED lights indicating that you can
apply reverb. This switch is off when you turn on the mixer. (Unlike
other switches, this switch cannot be locked.)
$REVERB TYPE/TIME control
Determines the reverb type and its length. Turning the control
toward the right lengthens the time of the selected reverb type.
HALL: Simulated reverb of a large space, such as a concert
hall.
PLATE: Simulated metal plate reverb, producing a more hard-
edged and bright sound.
ROOM: Simulated acoustic ambience of a small room.
ECHO: Echo effect suitable for vocals.
%REVERB controls (channels 1-4)
Determines the amount of reverb for each channel when the
REVERB switch (#) is on.
@Equalizer controls (HIGH, LOW)
This two-band equalizer adjusts the channel’s high and low
frequency bands. Setting the control to the “D” position
produces a flat response in the corresponding band. Turning the
control clockwise boosts the selected band. If you start getting
feedback, turn the control back slightly.
ALEVEL controls
Use these controls to adjust the volume for each channel. To reduce noise, set any LEVEL controls on
unused channels to the minimum.
&LEVEL meter
The LEVEL meter shows the level of output signal from the SPEAKERS L/R jacks.
Caution
If used at a high volume so that the LIMITER LED flashes continuously, the internal power
amplifier section is being excessively overloaded and may malfunction. Reduce the output level
with the MASTER LEVEL control so that the indicator flashes only briefly on the highest transient
peaks.
*POWER LED
This LED lights when the power is turned on by pressing the power switch.
(FEEDBACK SUPPRESSOR switch/LED
When this switch is on, the LED lights indicating that feedback is automatically suppressed.
(This utilizes a seven-band notch filter. When this switch or the power switch is off, the notch
filter will be reset.)

Troubleshooting
Power does not turn on.
 Did you rmly and securely connect the
power cord?
Power shuts down suddenly.
 Are the vents of the mixer blocked?
Since inadequate ventilation can result in
overheating the mixer, the power may be
turned off automatically to protect from
overheating. Secure the ventilation for
cooling, then turn on the power again.
No sound is heard.
 Did you connect the mixer’s SPEAKERS
jacks and the speakers’ input jacks
using the proper speaker cables?
 Did you rmly and securely connect the
speaker cables?
 Is a speaker other than the included
speaker (MODEL 400S) connected to
the mixer’s SPEAKERS jacks?
Please connect the included speaker
(MODEL 400S).
 Did you use the included speaker
cables?
If you use a commercially-available
speaker cable with a metal-housing
connector, the cable will be shorted
when the connector touches other metal,
resulting in no sound being produced.
 Is the POWER LED ashing at intervals?
There may be a short in the speaker cable
or the connection may be faulty. Check
that the speaker cable is not scratched
and is connected properly to the mixer,
then reapply the power.
 For channels 5/6, are both phone and
RCA-pin jacks connected at the same
time? Or, for channels 7/8, are both
phone and stereo mini jacks connected
at the same time?
The phone jack has priority for channels
5/6 and the stereo mini jack has priority for
7/8.
 Is the POWER LED ashing
continuously?
If the internal power amplifier section is
excessively overloaded, the amplifier will
be muted for protection. The mixer will
automatically reset itself after a while.
Sound is distorted or noise is
produced
 Are the LEVEL controls of all relevant
channels and/or the MASTER LEVEL
control set too high?
 Is the MIC/LINE switch of the
corresponding channel set to MIC?
If the input level from the source is high,
setting the MIC/LINE switch to MIC may
result in distorted sound. Set the switch to
LINE position.
 Is the volume of the connected device
too high?
Lower the volume of the external device.
 Is the speaker cable or the power cord
located near the input cables?
Please keep it away from the input cables.
Sound is not loud enough
 Are the LEVEL controls of all relevant
channels and/or the MASTER LEVEL
control set too low?
 Is the MIC/LINE switch of the
corresponding channel set to LINE?
Turn the LEVEL control to the minimum
(zero). Set the switch to the MIC position,
then slowly raise the LEVEL control.
 Is the volume of the connected device
too low?
Raise the volume of the external device.
 Is the PHANTOM switch set to on when
using a microphone that requires
phantom power?
The high sounds and low
sounds are unbalanced.
 Are the equalizer controls raised or
lowered too much?
Set the equalizer controls to the center
position.
 Is the speaker properly outputting the
high-frequency range signals?
If not, check the “Protective circuit (poly
switch)” note in the Notice section.
iPod/iPhone is not recognized
 Is your iPod/iPhone charged?
If your iPod/iPhone has not been charged,
it may take some time to be recognized by
the mixer. Make sure that your iPod/iPhone
is connected to the mixer and wait until it is
sufficiently charged.
