Yamaha STAGEPAS 150M Owner's Manual

Introduction
Thank you for your purchase of the Yamaha PORTABLE PA SYSTEM STAGEPAS 150M. The STAGEPAS 150M
is a versatile, compact PA system consisting of a speaker and a mixer.
In order to get the most out of your new STAGEPAS 150M and its sophisticated functions, we suggest you
read through this manual thoroughly. Also keep it in a safe place for future reference.
Features
● Two-way, 8-inch (20 cm) speaker system
The built-in speaker delivers high-quality powerful sound from an exceptionally compact cabinet.
The scratch-resistant speaker is rugged enough for outdoor use.
● Powered mixer
The powered mixer is a convenient, high-performance all-in-one unit that includes EQ and reverb. With two
monaural inputs and three stereo inputs, the STAGEPAS 150M can be connected to a wide range of
instruments and devices.
● Convenient storage
The STAGEPAS 150M can be used in even the most cramped quarters, inside or outside, since the mixer is
built into the speaker cabinet.

Troubleshooting Troubleshooting Troubleshooting
Power does not turn on
• Is the included power cord correctly connected to a power outlet?
Power shuts down suddenly
• Is the volume set at high for an extended period of time?
If the mixer is used at a volume beyond the permissible level, the protection circuit automatically turns the
power off. Turn on the power again only after the mixer cools, since it cannot be turned on until the internal
temperature goes down. Reduce the volume with the MASTER LEVEL control so that the LIMITER indicator
flashes only briefly in response to the highest transient peaks.
• Is the vent on the top panel of the mixer blocked?
Since inadequate ventilation can result in overheating the mixer, the protection circuit may come on
automatically and the power may be turned off. Turn on the power again only after the mixer cools, since it
cannot be turned on until the internal temperature goes down.
No sound is heard
• Are external instruments (including a microphone) or speakers correctly connected to the mixer?
• Are the LEVEL controls of all relevant channels and/or the MASTER LEVEL control set to appropriate levels?
• Is the SPEAKER jack connected to the included speaker (300S)?
• Is the POWER indicator flashing? There may be a short in the speaker cable or the connection may be
faulty. Check that the speaker cable is correctly connected to the mixer and reapply the power.
• Is the CLICK switch (for headphones) set to OFF?
• If sound is not still output, contact your Yamaha dealer.
Sound is distorted or noise is produced
• Are the LEVEL controls of all relevant channels and/or the MASTER LEVEL control set to appropriate levels?
• Are the MIC/LINE switches of each channels set appropriately?
• Are both XLR type and phone type jacks on channels 1–2 being used (connected) at the same time?
Please connect to only one of these jacks on each channel.
• Is the input signal from the connected device set to an appropriate level?

Outputting the signal to a main mixer
• Connect a main mixer to the ST SUB OUT jack. The ST SUB OUT jack outputs the signal prior to routing
through the MASTER LEVEL control. Adjust the level of output signal from the ST SUB OUT jack with the ST
SUB OUT control. The ST SUB OUT control does not affect the MASTER LEVEL control. If only the L (left)
ST SUB OUT jack is used, the mixer mixes the left and right signals and sends them to the jack.
