Fire or electrical shock may result. • Connect this unit’s power cord only to an AC outlet of the type stated in this Owner’s Manual or as marked on the unit. Failure to do so is a fire and electrical shock hazard. • Do not scratch, bend, twist, pull, or heat the power cord. A damaged power cord is a fire and electrical shock hazard. • Do not place heavy objects, including this unit, on top of the power cord. A damaged power cord is a fire and electrical shock hazard. In particular, be careful not to place heavy objects on a power cord covered by a carpet. • If you notice any abnormality, such as smoke, odor, or noise, or if a foreign object or liquid gets inside the unit, turn it off immediately. Remove the power cord from the AC outlet. Consult your dealer for repair. Using the unit in this condition is a fire and electrical shock hazard. • Should this unit be dropped or the cabinet be damaged, turn the power switch off, remove the power plug from the AC outlet, and contact your dealer. If you continue using the unit without heeding this instruction, fire or electrical shock may result. • If the power cord is damaged (i.e., cut or a bare wire is exposed), ask your dealer for a replacement. Using the unit with a damaged power cord is a fire and electrical shock hazard. • Do not remove the unit’s cover. You could receive an electrical shock. If you think internal inspection, maintenance, or repair is necessary, contact your dealer. • This unit has ventilation holes at the rear to prevent the internal temperature rising too high. Do not block them. Blocked ventilation holes are a fire hazard. • Clean the contacts of the phone plug before connecting it to the SPEAKERS jack of this unit. Dirty contacts may generate heat. • Use only speaker cables when connecting speakers to amplifier outputs. Using other types of cables is a fire hazard. Hold the power cord plug when disconnecting it from an AC outlet. Never pull the cord. A damaged power cord is a potential fire and electrical shock hazard. • Do not touch the power plug with wet hands. Doing so is a potential electrical shock hazard. • The digital circuits of this unit may induce a slight noise into nearby radios and TVs.

Response is flat when the knobs are in the ▼ position. Rotating it toward the right will boost the corresponding frequency band, and rotating it toward the left will cut it. The base frequency (or center frequency), range of boost or cut, and equalizer type of each band are as follows. HIGH: 12 kHz ±15 dB shelving type MID: 2.5 kHz ±15 dB peaking type LOW: 80 Hz ±15 dB shelving type EMX660—Owner’s Manual For each channel, this controls the amount of signal that is sent to the MONITOR bus. The signal of the MONITOR bus is sent to the speakers connected to the POWER AMP 2 A/B jacks (only if the power amp select switch is in the MAIN-MONITOR position) and to the MONITOR jacks (input/output panel 6). +15 MID 5 2 Monitor controls (MONI) Note: The signal is sent to the MONITOR bus from a location before the level control (4) of each channel. This means that it will not be affected by the setting of the LEVEL control. 3 Effect control (EFFECT) For each channel, this controls the amount of signal that is sent to the EFFECT bus. The signal of the EFFECT bus is sent to the builtin effect and to the EFFECT OUT jacks (input/ output panel 3). Note: The signal is sent to the EFFECT bus from a location after the level control (4) of each channel. This means that the amount of signal that is sent to the EFFECT bus will be affected not only by the setting of the effect control, but also by the setting of the level control. 4 Level control (LEVEL) This adjusts the output level for each channel. 5 Pad switch (PAD) (Channel 1–4 only) This switch attenuates the input signal by 30 dB. When connecting a line level device to channels 1–4, or if the mic input is distorted, turn this switch on (the pressed-in position).  5 Control panel ■ DIGITAL EFFECT section ■ MONITOR section This section allows you to turn the built-in digital effect on/off and to select the effect type. This section allows you to adjust the tone and volume of the MONITOR bus, and specify the mix level of the built-in effect and the external input signals. 8 VO. ECHO 1 VO. ECHO 2 VO. REV. 1 VO.

The indicator of the selected effect type lights up. 7 DIGITAL EFFECT ON switch and indicator When this switch is on (pressed), the indicator lights up and the built-in digital effect can be used. In that case, the signal processed by the digital effect will be sent to the MAIN/MONITOR bus. The mix level of the effect sound is adjusted by the EFFECT RTN control of the MAIN and MONITOR sections. This is a 7-band graphic equalizer that allows you to adjust the frequency response of the MONITOR bus signal, providing a maximum of ±12 dB of cut/boost for each frequency band. You can use these sliders to reduce the level of frequency bands at which feedback easily occurs. Frequency response is flat when a slider is in the center position. Moving a slider in the positive direction will boost, and in the negative direction will cut. This graphic equalizer affects both the MONITOR bus signal that is output to the speakers and the line level signal which is output from the MONITOR jack (input/output panel 6). 9 EFFECT RTN control This controls the level of the effect sound which is returned from the built-in digital effect to the MONITOR bus. 0 TAPE IN control This controls the level of the signal routed from the TAPE IN jack to the MONITOR bus. A MASTER control This adjusts the final level of the MONITOR bus. It affects both the MONITOR bus signal which is output to the speakers and the line level signal which is output to the MONITOR jack (input/ output panel 6). B Peak level indicator This indicator allows you to monitor the level of the signal which is output from the MONITOR jack (input/output panel 6). Note: To avoid distortion, adjust the MASTER control (A) so that the 0 indicator lights occasionally.

Microphones can be connected to the MIC jacks, and stereo line level devices (such as synthesizers or rhythm boxes) can be connected to the LINE jacks. The MIC jacks are balanced, and are compatible with microphones of output impedance 50– 600Ω. The LINE 1 & 2 jacks are unbalanced, and are compatible with line level devices of 600Ω output impedance. These two input jacks can be used simultaneously. Nominal input level is –50 dB for the MIC jacks and –10 dB for the LINE jacks. INST 1 & 2 jacks are unbalanced, can be used simultaneously, and their high input impedance makes them ideal for use with instruments such as electric-acoustic guitar and electric bass. They can also be used with line-level sources, such as synthesizers and drum machines. Nominal input level is –30 dB. Note: It is possible to simultaneously use both the MIC and LINE inputs for channel 5, and the MIC and INST inputs for channel 6. + Note: It is not possible to simultaneously use both the Hi-Z and Lo-Z inputs of a given channel. For each channel, use only one of the inputs as appropriate for the input source. Phantom power is switched on/off in simultaneously for the Lo-Z jacks of channels 1–4 and the MIC jacks of channels 5–6. For this reason, any devices other than condenser microphones must be connected to the Hi-Z or LINE jacks if the PHANTOM switch (control panel L) is on. EMX660—Owner’s Manual 1 2 MIC, LINE, INST input jacks These are the input jacks for channels 1–4. By using the PAD switches (control panel 5) you can connect any of the jacks to a wide range of sources from mics to line level devices (synthesizers or rhythm boxes etc.). The Lo-Z jacks can provide +15 V phantom power, allowing you to use condenser microphones. Both Hi-Z and Lo-Z are balanced, and are compatible with microphones of output impedance 50–600Ω or line level devices of 600Ω. The nominal input level is –40 dB – –10 dB for the Hi-Z jacks, and –50 dB – –20 dB for the Lo-Z jacks. Pin connections for the Hi-Z and Lo-Z jacks are as follows. Lo-Z jacks (XLR type) EEEngine 1 3 Effect output jack (EFFECT OUT) The input of an external effect such as a delay or echo can be connected to this jack. The signal adjusted by the EFFECT control of each channel will be sent to the EFFECT bus, and output from this jack. The nominal output level and impedance are +4 dB/10 kΩ. 4 Foot switch jack (FOOT SW) A separately sold Yamaha FC5 foot switch can be connected to this jack. If a foot switch is connected to this jack, you can use your foot to switch the built-in digital effect on/off.  Input/output panel 9 5 External input jacks (AUX IN/TAPE IN) These are input jacks that allow the signal from an external device to be added to the MAIN output. Monaural output devices such as external effects can be connected to the AUX IN jack, and stereo output devices such as cassette recorder or CD players can be connected to the TAPE IN jacks. The nominal input level and impedance are –10 dB/ 600Ω for the AUX IN jack, and –10 dBV/600Ω for the TAPE IN jacks. 6 External output jacks (REC OUT/MONITOR/MAIN) These are output jacks which send line level signals from the EMX660 to external devices. A stereo recording device such as a cassette deck, DAT 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 jacks. The signals sent from each jack are as follows. • REC OUT jacks: The MAIN bus signal before it has passed through the MASTER control and graphic equalizer • MONITOR jack: The MONITOR bus signal which has passed through the Monitor MASTER control and graphic equalizer • MAIN jack: The MAIN bus signal which has passed through the Main MASTER control and graphic equalizer The nominal output level and impedance are –10 dBV/10 kΩ for the REC OUT jacks, and +4 dB/10 kΩ for the MONITOR/MAIN jacks. EMX660—Owner’s Manual  10 Front and rear panel Rear panel 2 POWER ON / OFF 1 Speaker output jacks (POWER AMP 1 A/B, POWER AMP 2 A/B, BRIDGE) Speakers can be connected to these jacks. The EMX660 contains a two-channel power amp, and there are three ways in which the speakers can be connected to the EMX660. At this time, use the power amp select switch J on the control panel to select a signal sent to the correct jacks. ■ When the power amp select switch is set to MAIN-MONITOR or MAIN-MAIN: • Two-channel connection Two 4–8Ω speakers can be connected to the A jack or B jack of the POWER AMP 1/2 (maximum output 300W+300W). • Two-channel parallel connection Two 8–16Ω speakers can be connected to the POWER AMP 1 A/B jacks and two more to the POWER AMP 2 A/B jacks, for a total of four speakers (maximum output 300 W+300 W). ■ When the power amp select switch is set to MAIN-BRIDGE (Bridge connection) • One 8–16Ω speaker can be connected to the BRIDGE jack (maximum output 600 W).

EMX660—Owner’s Manual Normally, connect speakers to the jacks on the rear panel. If more speaker outputs are needed, use the MAIN (STEREO) jacks for stereo output and the MONITOR jack for monaural output.  Basic Operation 13 Basic Operation This section explains basic operation of the EMX660. Connecting microphones and instruments 1 Before connecting mics or instruments, make sure that the power of all equipment (where applicable) is turned off. Also make sure that the level controls of each channel of the EMX660 and the MASTER control of the MAIN section are turned down. 2 Connect cables to your mics and instruments, and insert the other end of the cable firmly into the appropriate Lo-Z/HiZ jack (channels 1–4) or the MIC jack (channels 5–6), LINE jack (channels 5), INST jack (channels 6). Note: When connecting a line level device to channels 1–4, turn on the PAD switch. You cannot use a channel’s Lo-Z and Hi-Z jacks at the same time. The MIC and LINE jacks, or the MIC and INST jacks, however, can be used at the same time. 3 Turn the power on in the order of peripheral devices ➞ EMX660. Note: When turning the power off, reverse this sequence. 4 Set the MAIN section MASTER control to the √ position. 5 While speaking into the mic (while playing the instrument), adjust the channel LEVEL control so that the 0 LED of the MAIN section peak level meter lights occasionally. Repeat this step for each channel. 6 If you wish to adjust the tone of each channel, rotate the equalizer controls as desired. 7 Use the MAIN section graphic equalizer to adjust the tone. 8 Use the MAIN MASTER control to adjust the overall volume. Monitoring By connecting a powered monitor speaker to the MONITOR OUTPUT, you can create a monitor mix independent of the MAIN mix, since the input channel MONI controls are not affected by the LEVEL controls. 1 Set the MONI MASTER control to the √ position. 2 While speaking into a connected mic, or playing a connected instrument, adjust the MONI control of the input channel that you want to monitor. Repeat this procedure for each channel. 3 Use the MONI MASTER control to set the overall level of the monitor mix. Using the digital effect The EMX660 has a built-in digital effect, allowing reverberation or ambiance to be added to vocals or instrumental sounds. 1 Press the DIGITAL EFFECT ON switch of the DIGITAL EFFECT section. 2 Use the effect select switches of the DIGITAL EFFECT section to select the effect type. VO.ECHO 1, 2 .....Echo appropriate for vocals. VO.REV. 1, 2........Reverb appropriate for vocals. HALL 1, 2 .............Reverb typical of a hall. ROOM ..................Reverb typical of a room. PLATE .................Plate echo-like reverberation 3 Set the MAIN EFFECT RTN control to the √ position. 4 Raise the EFFECT control of the channels to which you wish to apply the digital effect. 5 Use the MAIN/MONITOR section EFFECT RTN control to adjust the level of the sound processed by the effect. Note: If the effect sound is distorted even if the EFFECT RTN turned all the way down, lower the EFFECT controls of each channel.

In this example, the monitor speakers are being sent a mix that is independent of the MAIN speaker mix. An external effect such as delay or reverb is also being used. Connections Note: Set the power amp select switch of the POWER AMP section to the “MAIN MONITOR” position. If you are using an external effect, we recommend that you turn down the EFFECT RTN controls of the MAIN and MONITOR sections. If the external effect has a stereo output, it is possible to connect its output jacks to the LINE jacks of channels 5. However in this case, be sure that the EFFECT controls are turned all the way down for the channels into which the effect sound is being input. If the EFFECT controls are raised, feedback will occur, and your speakers may be damaged. • Connect mics or instruments, such as keyboards, to the channel input jacks 1–6. • Connect the main speakers to the POWER AMP 1 A/B jacks, and connect the monitor speakers to the POWER AMP 2 A/B jacks. • If you will be using an external effect such as delay or reverb, connect the EMX660’s EFFECT OUT jack to the input jack of the external effect, and connect the output jack of the external effect to the EMX660’s AUX IN jack.

Although this example shows an external effects processor and footswitch, which is used to turn on and Footswitch off the built-in digital effects process(YAMAHA FC5) or, connected to the EMX660, in practice, only one effects processor, internal or external, will be used at a time, so the footswitch is not required when using external effects. EMX660—Owner’s Manual  16 Example setups Sending an independent mix to the monitor speakers 1 Set the MONITOR section MASTER control to the √ position. 2 Raise the MONI controls for the channels that you wish to hear from the monitor speakers. Note: The MONI controls are not affected by the level settings of each channel. This allows you to create a mix that is independent of the MAIN section. 3 Use the graphic equalizers and MASTER controls of the MAIN/MONITOR sections to adjust the overall volume and tone. EMX660—Owner’s Manual Using an external effect 1 Raise the EFFECT controls for the channels to which you want the external effect to be applied. 2 Adjust the input level of the external effect so that the sound is not distorted at the input of the external effect. 3 Use the MAIN section AUX IN control to adjust the level of the sound processed by the effect.  Troubleshooting 17 Troubleshooting The following table describes the possible malfunctions of this device, and the appropriate actions to be taken in each case.
