The signal of the MONITOR bus is sent to the speakers connected to the SPEAKERS B 1/2 jacks (only if the power amp select switch is in the MAIN-MON position) and to the MONITOR jacks (input/output panel 6). MID 1 +15 –15 LOW +15 –15 MONITOR 2 0 +15 EFFECT 3 +15 0 LEVEL 4 10 0 5 PAD 1 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 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 control adjusts the level of signals routed from each channel to the MAIN bus and to the built-in power amplifier. The MAIN bus signal is sent to the MAIN jacks (input/output panel 6) and the SPEAKERS jacks on the rear panel 1. 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).

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 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 –40 dB – –10 dB for the Hi-Z jacks, and –50 dB – –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) Hi-Z jacks (TRS phone jacks) Pin 1: ground Sleeve: ground Pin 2: hot (+) Tip: hot (+) Pin 3: cold (–) Ring: cold (–) S + - GND 3 4 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 simultaneously for the Low-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 K) is on. These are the input jacks for channels 5–6. 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. Super Hi-Z 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 Super Hi-Z inputs for channel 6. 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 (control panel 3) of each channel will be sent to the EFFECT bus, and output from this jack. The nominal output level and conforming impedance are +4 dB/10 kΩ. EMX66M—Owner’s Manual  14 Front and rear panel 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. 5 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. 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 2TR IN jacks. The nominal input level and impedance are –10 dB/ 600Ω for the AUX IN jack, and –10 dBV/600Ω for the 2TR IN jacks. 6 REC OUT/MAIN/MONITOR—OUTPUT jacks These are output jacks which send line level signals from the EMX66M 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 • MAIN jack: The MAIN bus signal which has passed through the Main MASTER control and graphic equalizer • MONITOR jack: The MONITOR bus signal which has passed through the Monitor 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.

Other Powered Mixer Q&A Q: The built-in effect is not effective. A: The ON switch in the DIGITAL EFFECT section may not be turned on. Or, you have adjusted the EFFECT control in the Channel section or the EFFECT RTN control in the MAIN section. Q: The monitoring sound from the speakers is not powerful enough relative to the level of the input sound. A: The equalizer LOW control for each channel may be set to negative values. Q: The stereo output from the synthesizer has been routed to the Super Hi-Z jack of channel 6, but the monitoring sound is not stereo. A: You can use Super Hi-Z (or LINE) 1 and 2 jacks at the same time. However, they are internally routed into a mono channel, and therefore the signals from 1 and 2 jacks are output as mono signal. Q: The signal is sent from the EFFECT OUT jack to the connected effect processor. Then the effect sound is returned to the AUX IN jack. However, no signal is input to the mixer. A: The AUX IN control in the MAIN section may not be rotated to right. Q: An external powered speaker is connected to the MONITOR-OUTPUT jack. However, the signal is not sent to the speaker even when the MASTER control in the MONITOR section is turned. A: The MONITOR controls for input channels may not have been adjusted. Q: Can the Low-Z jack and the Hi-Z jack be used at the same time? A: You cannot use the Low-Z jack and the Hi-Z jack for the same channel at the same time. Q: Can a single speaker be connected to the mixer? A: Yes. Use a speaker with an impedance of 4–8 Ω.
