PHONES control

Determines the signal level output from the

PHONES jack.

NOTE: The MASTER LEVEL control does not affect

the signal via the PHONES control.

Getting sound out of the system

Using the included speaker, set up the system and try it out.

1 Connect the included speaker and your instruments to the mixer.

Connect the included speaker (500S) to the SPEAKER jack. Connect the sources (microphone, other instruments) to the input jacks. For details, see “Connection Example.”

Before connecting any devices, make sure to turn off the power for all devices (including microphones).

Also, before turning the power on or off, set the volume levels on all devices to minimum.

NOTE: For best results when connecting an electric guitar or bass guitar to the mixer, use a direct box, preamp

(guitar amp), or amp simulator.

Set the mixer’s LEVEL controls and MASTER LEVEL control to the minimum (zero).

3 Depending on the device used, set the MIC/LINE switch to MIC ( ) or LINE

( ) as appropriate.

For low-level signals (such as that of microphones), set the switch to the MIC ( ) position.For high-level signals (such as keyboard instruments and audio equipment), set the switch to the LINE ( ) position.

NOTE: When using a condenser microphone, set the PHANTOM switch to ON.

4 Turning the power on

First, turn on the power to any connected devices, then turn the STAGEPAS 250M power on.If you’ve connected powered speakers to the mixer, turn on the power of the mixer first, then the powered speakers.

To avoid any loud, unexpected noise from the speakers, first turn on the power to those connected

devices that are closest to the sound source.

Example: Sound source (CD player or instrument) → STAGEPAS 250M → (Power amplifier) When turning off the power to the system, reverse the order described above.5

Set the MASTER LEVEL control to the optimum position (indicated by the arrow).

6 While playing your instrument or singing into the microphone, adjust the

LEVEL control of the corresponding channel.

Adjust the LEVEL Control of the corresponding channel so that the “0” LED lights up momentarily.

7 Use the MASTER LEVEL control to adjust the overall volume.

If the LIMITER indicator flashes continuously, the internal power amplifier section is being

excessively overloaded and may malfunction.

Applying reverb or echo to the sound

Reverb recreates the warm ambience of an actual performance space, such as a concert hall or a night club.

1 For each channel you want to apply reverb, set the corresponding REVERB

switch to ON ( ).

2 Use the REVERB control to adjust the overall reverb.

Caution

¡ SPEECH/MUSIC switch

Set this switch to SPEECH ( ) to optimize

the mixer settings and sound quality for

speech purposes and announcements.

Set this to MUSIC ( ) to optimize the mixer

for musical performance. The switch lights up

in yellow when it is set to MUSIC ( ).

* LEVEL control

Use these controls to adjust the volume

balance among the various channels.

To reduce noise, set any LEVEL

controls on unused channels to

the minimum.

( MASTER LEVEL Control

Determines the volume of the signal output

from the SPEAKER jack. This allows you to

adjust the overall volume without changing

the relative volume balance among the

various channels (made with the LEVEL

controls) or the tone settings (made with the

Equalizer).

Caution

% REVERB switch

Set this switch to ON to recreate the rich ambience

of various performance environments, such as a

concert hall or a night club. The switch lights up in

green when REVERB is ON ( ).

^ REVERB control

Determines the overall level of the reverb or echo

that is applied to the output signal. For best results,

this level should not be set very high, to avoid

possible feedback and to prevent the sound from

becoming “muddy” with too much reverb.

$ Equalizer

HIGH:

Determines the level of the high frequency band

for each channel. Rotating the knob clockwise boosts

the high frequencies and produces a clearer, crisper

sound. If you start getting feedback (a high-pitched

squealing sound) or you want to make the sound softer

and less harsh, turn the knob counterclockwise slightly.

LOW:

Determines the level of the low frequency band

for each channel. Rotating the knob clockwise boosts

the low frequencies and produces a deeper, warmer

sound. If you start getting feedback or you want to make

the sound less boomy, turn the knob counterclockwise

slightly.

# LIMIT/COMP switch

Set this switch to COMP ( ) to apply compression, or set it to LIMIT ( ) to apply limiting. By compressing excessive peaks of input signals and bringing up the level of overly soft parts, compression raises the overall volume without introducing distortion. Compression can be used to make a mix sound louder and have more punch. The Limiter is used to suppress excessive input signals and bring them down to an adequate level. The switch lights up in yellow when it is set to COMP ( ).

1 AC IN jack

Connect the included power cord here.

Be sure to use the included power

cord. Use of other cords may result

in malfunction, heat generation, or

fire.

2 POWER switch

For turning the power to the mixer on and off.

3 SPEAKER jack

(for included speaker 500S only)

This outputs the mixed monaural L+R signal

channels from 1 to 9/10 and the level is adjusted

with the MASTER LEVEL control. Connect only the

included speaker (500S).

4 ST LINK OUT R jack

This outputs signals from R (even) channels only.

When inserting a plug to this jack, only signals from

the L (odd) channels are supplied to the SPEAKER

jack. The output level is adjusted with the MASTER

LEVEL control. Used with the SPEAKER jack, this lets

you output the signals in stereo from the speakers.

PHONES jack

This outputs the mixed signal channels from 1 to

9/10, and the level is adjusted with the PHONES

control. Connect a set of headphones here.

ST SUB OUT L (MONO) / R jacks

These output the mixed signal channels from 1 to

9/10, and the level is adjusted with the ST SUB

OUT control. You can use these jacks, for example,

to connect a main mixer. These impedance

balanced jacks allow a longer cable to be

connected with the use of a balanced cable.

9 Channel input jacks (CH 1, 2)

For connecting a guitar, microphone, keyboard or other instrument/device. Set the MIC/LINE switch to MIC

or LINE for channels 1, 2, depending on the level of the input signal.

XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).

NOTE: On any given channel, you may use either XLR or phone jack, but not both. Please connect to only one of

these jacks on each channel.

) Stereo channel input jacks (CH 3/4, 5/6, 7/8, 9/10)

Input the left and right channels of a stereo signal into the respective odd and even channels of the mixer.

These inputs are intended mainly for use with instruments and equipment having stereo outputs, such as a

synthesizer or CD player.

NOTE: The channel 9/10 input provides two sets of jacks—both phone jacks and RCA-pin jacks. Either one of these

jacks may be used, but not both at the same time. Please connect to only one of these jacks on each

channel.

! MIC/LINE switch

Set this switch to MIC or LINE for channels 1, 2, depending on the level of the input signal. For low-level

signals (such as that of microphones), set the switch to the MIC ( ) position. For high-level signals (such

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

To avoid damage to speakers, be sure to turn off amplifiers (or powered speakers) before setting

this switch to MIC or LINE. We also recommend that you turn the MASTER LEVEL control to the

minimum setting before operating the switch, to avoid excessively loud noises that could cause

hearing loss or device damage.

™ LEVEL meter

The LEVEL meter shows the level

of the output signal from the

SPEAKER jack.

If the LIMITER 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 indicator

This lights when the POWER switch

is ON. When the indicator flashes,

the protection circuit is operating.

Check that the speaker cable is

correctly connected to the mixer

and reapply the power.

@ PHANTOM switch

If you set the switch on, the mixer supplies phantom power on to the XLR mic input jacks on the channels 1, 2.

• Be sure to leave this switch OFF if the device or instrument that you are using does not require

phantom power.

• When using phantom power, do not connect any devices other than condenser microphones to

the XLR input jacks. Other devices may be damaged if connected to phantom power. This

precaution does not apply to balanced dynamic microphones, however, as these will not be

affected by phantom power.

• To avoid damage to speakers, be sure to turn off amplifiers (or powered speakers) before

turning this switch on or off. We also recommend that you turn the MASTER LEVEL control to

the minimum setting before operating the switch, to avoid excessively loud noises that could

cause hearing loss or device damage.
