input jack of the mixer.

Refer to the illustration on the mixer shown below or the connection example of the cover

panel of the accessory compartment.

Getting sound out of the system

Connect the included power cord.

First, connect it to the mixer’s AC IN connector, then

to a power outlet.

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 “ ” or D

“MUSIC” position.

Set the MIC/LINE switch to the MIC ( ) N

position for microphone connection, and to

the LINE ( ) position for connection of an O

instrument or audio device.

Turn on the power of the connected sound

source (if applicable), then the mixer.

The POWER LED lights.

Set the MASTER LEVEL control to the “ ” position.D

While playing your instrument or singing into the microphone, use the

LEVEL control to adjust the volume of the corresponding channel.

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).

Mixer Controls and Functions

1 Mic/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.

2 MIC/LINE switches (channels 1-4)

For low-level signals (including microphones), set the switch to the MIC ( ) position. For high-level signals (including electronic N

instruments and audio equipment), set the switch to the LINE ( ) position.O

3 Hi-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.

4 Line (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.

RCA-pin stereo-mini

5 MONITOR 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).

7 REVERB 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.

8 SPEAKERS L/R jacks

Use the included speaker cables to

connect the speakers.

9 USB 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.”

D Vents

These are the vents for the cooling fan

inside the mixer. Do not block the vents

when in use.

E AC IN jack

Connect the included power cord here.

F (power) switch

For turning the power of the mixer on ( ) and off ( ).O 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 ( ) position, then slowly raise the LEVEL O

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 ( ) position, then slowly raise the LEVEL control N

until the desired volume is reached.

^ ST/MONO switches (channels 5/6, 7/8)

Setting the switch to ST (STEREO) ( ) will assign the signals from the L and R channels to N

each left and right speaker and output each signal. Setting the switch to MONO ( ) will mix O

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. B MASTER 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.

C MASTER 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.

Press down the REVERB switch to turn it on.

The LED lights when REVERB is on.

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.

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.

Long

) 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 “ ” position D

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.

A LEVEL 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.)
