The EMX88S/EMX68S has the following features. In order to take full advantage of the EMX88S/EMX68S and enjoy long and trouble-free performance, please read this owner’s manual carefully, and keep it in a safe place for future reference. Features • The EMX88S/EMX68S features eight input channels (EMX88S), six input channels (EMX68S) that support a wide range of audio sources, from microphones to line-level devices. The microphone input for each channel has +15 V phantom power for use with condenser-type microphones. • Two powerful main amps are built-in to deliver 400W + 400W (800W monaural when bridged). According to your needs, the output signal to the power amps can be either stereo [MAIN L-R], [MAIN (L+R)] + monitor [MAIN (L+R) - MON], or [MAIN (L+R)] (bridge connection). ■ Stereo The stereo-mixed main signal will be output from speaker output jacks A and B of the EMX88S/ EMX68S. Either one or two speakers can be connected to each set of speaker jacks. ■ [MAIN (L+R)] + monitor The monaural-mixed main signal will be output from speaker jacks A of the EMX88S/EMX68S, and the monitor signal will be output from speaker jacks B. Either one or two speakers can be connected to each set of speaker jacks. ■ [MAIN (L+R)] (bridge connection) The two power amps will be bridged, and the monaural-mixed main signal will be output from the BRIDGE jack. This allows high-volume output when using only one speaker. • Individual seven-band graphic equalizers are provided to the main and the monitor sections. In this way, you can individually adjust the volume level and frequency response of the main speakers and monitor speakers. • Two limiter circuits are built-in to prevent excessive input levels to the amp. • The 16 built-in effect types are equivalent in quality to those of the acclaimed Yamaha SPX series of multieffect units, and allow a variety of effects to be applied to add reverb or ambience to vocals or instruments. The16 types include TAP DELAY, which lets you easily adjust the delay time. less, and reduced heat generation to 35% or less (in field applications, compared to Yamaha’s previous models), and has lead to a reduction in energy cost and to less-restrictive installation requirements related to heat generation.

EMX88S/EMX68S—Owner’s Manual  10 Front and rear panel Front and rear panel Control panel ■ Channel section Use these controls to adjust factors such as the equalization, (frequency response), volume, effect and monitor output level for the input signal to each channel. 1 2 MONITOR control 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 MONITOR jacks (input/output panel 7). Note: The signal is sent to the MONITOR bus from a location before the level control (5) of each channel. This means that it will not be affected by the setting of the Level control. 3 EFFECT control 2 3 4 5 6 1 Equalizer controls (HIGH, MID, LOW) This is a 3-band equalizer that adjusts the high frequency range, mid frequency range, and low frequency range of each channel. 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: 10 kHz ±15 dB shelving type MID: 2.5 kHz ±15 dB peaking type LOW: 100 Hz ±15 dB shelving type EMX88S/EMX68S—Owner’s Manual 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 digital effect, and to the EFFECT OUT jacks (input/output panel 4). Note: The signal is sent to the EFFECT bus from a location after the level control (5) 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 PAN control (BAL/PAN control for CH7/8 (EMX88S), CH5/6 (EMX68S)) This knob adjusts the stereo image (L/R) for each channel. Adjust for equal volume on left and right with a sound source input to the CH7 and 8 (EMX88S), CH5 and 6 (EMX68S) LINE connectors (L/R). 5 LEVEL control This adjusts the output level for each channel. 6 PAD switch (1–6 (EMX88S) only, 1–4 (EMX68S) only) This switch attenuates the input signal by 30 dB.

EMX88S/EMX68S—Owner’s Manual  14 Front and rear panel Input/output panel 2 4 1 3 1 Channel input jacks (Hi-Z, Low-Z) Pin 1: ground Pin 2: hot (+) Pin 3: cold (–) Hi-Z jacks (TRS phone jacks) Sleeve: ground Tip: hot (+) Ring: cold (–) S + - GND R T GND - + Note: It is not possible to simultaneously use both the Hi-Z and Low-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 channels 1–8 (EMX88S), 1–6 (EMX68S). For this reason, devices which do not require phantom power must be connected to the Hi-Z or LINE jacks if the PHANTOM switch (control panel L) is on. EMX88S/EMX68S—Owner’s Manual 6 7 2 Super Hi-Z jacks 1–6 (EMX88S), 1–4 (EMX68S) These are the input jacks for channels 1–6 (EMX88S), 1–4 (EMX68S). By using the PAD switches (control panel 6) 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 Low-Z jacks can provide +15 V phantom power, allowing you to use condenser microphones. Both Hi-Z and Low-Z are balanced, and are compatible with microphones of output impedance 50–600Ω or line level devices of 600Ω. The nominal input level is from –40 dB to –10 dB for the Hi-Z jacks, and from –50 dB to –20 dB for the Low-Z jacks. Pin connections for the Hi-Z and Low-Z jacks are as follows. Low-Z jacks (XLR type) 5 These two phone jacks are the input connectors for input channel 5–6 (EMX88S), 3–4 (EMX68S). They 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. 3 Channel input jacks (MIC/LINE) 7–8 (EMX88S), 5–5 (EMX68S) These are the input jacks for channels 7–8 (EMX88S), 5–6 (EMX68S). Connect microphones to the MIC jacks. Connect line-level devices, such as synthesizers to LINE L (MONO)/R jacks if the devices are stereo sound sources. Use the LINE L (MONO) jack if the devices are monaural sound sources. The MIC jacks can provide +15 V phantom power, allowing you to use condenser microphones. The MIC jacks are balanced, and are compatible with microphones of output impedance 50– 600Ω. The LINE jacks are unbalanced, and are compatible with line level devices of 600Ω output impedance. Nominal input level is –50 dB for the MIC jacks and –10 dB for the LINE jacks. Note: The MIC and LINE inputs for channel 7 (EMX88S), 5 (EMX68S) can be used simultaneously but their levels cannot be adjusted separately (Same for channel 8 (EMX88S), 6 (EMX68S).)  Input/output panel 4 EFFECT OUT jack 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, its level adjusted by the EFFECT OUT control, and output from this jack. The nominal output level and impedance are +4 dB/10 kΩ. 5 FOOT SW jack 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. 6 AUX IN/2TR IN-INPUT TO MAIN jacks These are input jacks that allow the signal from an external device to be added to the MAIN output. • AUX IN jacks: Connect these jacks to the output jacks of an external effects processor. If the effects processor has a stereo output, connect it to the AUX IN L (MONO) and R jacks. If it has monaural output, use the AUX IN L (MONO) jack. Signal input to these jacks is sent to the stereo (MAIN L, R) bus. 15 7 REC OUT/MAIN (STEREO)/MONITOROUTPUT jacks These are output jacks which send line level signals from the EMX88S/EMX68S 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. The signals sent from each jack are as follows. • REC OUT jacks: The stereo (MAIN L, R) 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 (STEREO) jack: The stereo (MAIN L, R) 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 (STEREO) jacks. • 2TR IN jacks: Use these jacks to connect a stereo device, such as a cassette player or a CD player. The signals input to these jacks is sent to the stereo (MAIN L, R) bus. The nominal input level and impedance are –10 dB/ 600Ω for the AUX IN jack, and –10 dBV/600Ω for the 2TR IN jacks.

Be sure to use cables designed for the purpose when you connect speakers to speaker jacks. ■ Connecting main speakers There are three ways in which speakers can be connected to the EMX88S/EMX68S. The speaker impedance requirement varies depending on how you connect the speakers. Refer to the diagrams below to make sure the speaker impedance will not be lower than the specified value. ■ When the power amp select switch is set to MAIN L-R or MAIN (L+R)-MON: • 2-channel connections Connect either one or two speakers each to jacks A and jacks B. If the power amp select switch is set to MAIN L-R, the signals of the MAIN L and MAIN R buses will be output respectively to the speakers connected to the A and B jacks. If the power amp select switch is set to MAIN (L+R)-MON, the summed signals of the MAIN L bus + R bus and the signal of the MONITOR bus will be output respectively to jacks A and B. For either setting of the switch, use speakers with an impedance in the range of 4–8 ohms if you are connecting only one speaker to each set of outputs. A maximum output of 400W + 400W will be obtained when 4ohm speakers are used. Power amp select switch Not used or 4Ω–8Ω 4Ω–8Ω • 2-channel parallel connections If you connect two speakers to each set of outputs, use speakers with an impedance in the range of 8–16 ohms. A maximum output of 400W + 400W will be obtained when 8-ohm speakers are used.
