Thank you for purchasing the Yamaha EMX860ST Powered Mixer. The EMX860ST has the following features. In order to take full advantage of the EMX860ST and enjoy long and trouble-free per- formance, please read this owner’s manual carefully, and keep it in a safe place for future reference.
15 dB peaking type LOW: 100 Hz 15 dB shelving type EMX860ST—Owner’s Manual Monitor controls (MONI) For each channel, this controls the amount of sig- nal that is sent to the MONI bus. The signal of the MONI bus is sent to the speak- ers connected to the MONITOR A/B jacks and to the MONITOR jacks (input/output panel 6 ).
EFFECT OUT control This adjusts the effect send level for an external effect device connected to the EFFECT OUT jack (input/output panel 3). Note: The EFFECT OUT control does not affect the level sent to the built-in digital effect. EMX860ST—Owner’s Manual...
• EFFECT RTN MONITOR Graphic equalizer The EMX860ST has a 7-band graphic equalizer for adjusting the frequency response of the MONI bus signal. This allows you to cut or boost each frequency band by a maximum of 12dB. You can use these sliders to reduce the level of fre- quency bands at which feedback easily occurs.
PHANTOM +48V POWER indicator This indicator will light when the power of the EMX860ST is turned on. PHANTOM +48 V switch This switch turns the phantom power supply on/ off for the Lo-Z input jacks of channels 1–6 and MIC input jacks of channels 7–8.
The nominal output level and impedance are +4 dB/10 k . Foot switch jack (FOOT SW) You can connect a Yamaha FC5 foot switch (sold separately) to this jack and use it to turn the built-in digital effect on and off. The Digital Effect ON switch on the front panel must always be set to ON in order to use the foot switch.

REC OUT/MONITOR/MAIN (STEREO) jacks These are output jacks which send line level sig- nals from the EMX860ST to external devices. A stereo recording device such as a cassette recorder or MD recorder can be connected to the REC OUT jacks, and a playback device such a power amp can be connected to the MONITOR and MAIN (STEREO) jacks.
Note: Do not connect anything to the SPEAK- ERS L/R jacks if you use this BRIDGE connec- tion. Power switch This switch turns the power of the EMX860ST on/off. Note: Before turning the EMX860ST on/off, turn down fully the MASTER controls of the MONITOR and MAIN section.
