Yamaha 250M Folheto

Set this switch to ON to assign the 

click/metronome sounds to only the 

PHONES jack when the CLICK switch 

at the channel 7/8 is ON.

Set this switch to ON to assign the 

click (metronome) sounds that sent 

to the channel 7/8 to the PHONES 

jack, SPEAKER jack, and ST LINK 

OUT R jack, but not to the ST SUB 

OUT jacks.

Setting this switch to ON lets the 

player monitor the click (metronome) 

sounds of a sequencer or a 

synthesizer.

Determines the signal level output from the ST SUB 

OUT jacks.

NOTE:  The MASTER LEVEL control does not affect 

the signal via the ST SUB OUT control.

Determines the signal level output from the 

PHONES jack.

NOTE:  The MASTER LEVEL control does not affect 

the signal via the PHONES control.

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

Connect the included speaker (500S) to the SPEAKER jack. Connect the sources (microphone, other 

instruments) to the input jacks. For details, see “Connection Example.”

 

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.

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.

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.

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

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

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 (      ).

Use these controls to adjust the volume 

balance among the various channels.

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).

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 (      ).

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.

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.

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 (      ).

Connect the included power cord here.

For turning the power to the mixer on and off.

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).

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.

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.

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.

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.

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.

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.

The LEVEL meter shows the level 

of the output signal from the 

SPEAKER jack.

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.

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