We also recommend that you turn all output controls (LEVEL knobs, MASTER knobs, etc.) to minimum settings before operating the switch, to avoid risk of loud noises that could cause hearing loss or device damage. Q LIMITER lamps The lamp lights up when the amplified signal being output at the corresponding SPEAKERS jack hits its maximum value. The lamp indicates that the limiter has come on. If the lamps are flashing frequently, the load on the amp is too high and there is risk of damage to your equipment. Reduce the setting of the MASTER knobs (G and M) until the lamps flash only briefly or not at all. R POWER AMP switch Selects the output that gets sent to the SPEAKERS jacks, as follows. Up (MAIN L/R): SPEAKERS jacks A1 and A2 output the signal from the MAIN L bus, and SPEAKERS jack B1 and B2 output the signal from the MAIN R bus. The MAIN section’s MASTER knob G adjusts the output level at all of the SPEAKERS jacks. Down (MAIN(L+R)/MON): SPEAKERS jacks A1 and A2 output a mix of the signals from the MAIN L and MAIN R buses. SPEAKERS jacks B1 and B2 output the signal from the MONITOR bus. The MAIN section’s MASTER knob G adjusts the level to the A jacks, while the MONITOR section’s MASTER knob M adjusts the level to the B jacks. S YS Processing switch This switch turns Yamaha Speaker Processing on or off. The processor adjusts the speaker’s bass ranges so as to compensate, for example, for lack of subwoofers. Note however that the resulting frequency balance will vary according to the speakers you are using. T STAND-BY switch This switch mutes the input to channels 1 to 8. The switch lights up to indicate that the mute has been turned on. Note that the mute does not work on channels 9 to 12. NOTE When using the mixer for live performances, you can fill in gaps in the performance by turning on the standby switch and feeding background music from a CD player or other such device into channels 9 to 12. U POWER switch and lamp This switch turns the EMX power ON and OFF. The lamp lights up to indicate that the power in on. Before turning the power ON or OFF, be sure to turn both MASTER knobs (G and M) to “0”. EMX512SC/EMX312SC/EMX212S 25 Controls and Connectors 26 EMX512SC/EMX312SC/EMX212S Rear Panel V SPEAKERS jacks Use these jacks to connect to speakers. Note that the output directed to these jacks varies according to the setting of the POWER AMP switch R. A1, B1: Neutrik NL4 Speakon outputs. Polarities are as shown below. A2, B2: Phone output jacks. W AC IN connector Connects to the included power cord. Connect one end of the cord to this connector, and then plug the other end into a standard power outlet. Please use the cord that comes with the mixer. Use of a different cord may pose risk of fire, burns, or equipment damage. X Ground Screw For maximum safety be sure to securely connect the EMX to an earth connection. The supplied power cable has a three-prong plug that will ground the unit when the plug is inserted into an appropriately grounded three-prong type AC mains outlet. If the AC outlet is not grounded, be sure to ground the unit by using this ground screw. Correct grounding will effectively eliminate hum noise and interference. W V X Neutrik Plug A1 and B1 Connectors 1+ 1– 2+ 2– 2+ 2- 1- 1+ + – Connecting Speakers Connecting Speakers s When making 2-channel and 2-channel parallel connections to the SPEAKERS jacks, be sure that the impedance of your speakers meets the conditions indicated below. Note that actual speaker impedance varies according to connection method and number of speakers. When making connections, be sure that your cables have the appropriate ratings and the correct plugs. Be sure to use dedicated speaker cables when connecting speakers to the SPEAKERS jacks. ¦ 2-channel connection When connecting by 2-channel connection, use speakers with impedance of 4 ohms to 8 ohms. 4. to 8. 4. to 8. ¦ 2-channel parallel connection When connecting speakers in parallel as shown below, use speakers with impedance of 8 ohms to 16 ohms. 8. to 16. 8. to 16. 8. to 16. 8. to 16.

The stabilizers prevent the unit from tipping over. Please detach the stabilizers when transporting the unit. ¦ How to attach the rubber stabilizers Turn the EMX unit upside down. Attach the two rubber stabilizers that were included with the unit. Push each stabilizer all the way in so that they are firmly in place. Turn the EMX right-side up.
