EMX66M Quick Guide Connecting a CD player, MD player, and/or cassette deck Connect a CD player or MD player to the 2TR IN jacks. Refer to the operation manual of the corresponding device for more information on the input and output of the device.
8 EMX66M Quick Guide STEP 2 Power on STEP 4 Applying built-in effects 1 Turn on the power to all external devices connected to the EMX66M. 2 Make sure that the MASTER controls in the MONITOR section and the MAIN section are set to “0,” then press the POWER switch on the EMX66M to turn on the power. 1 Turn on the ON switch in the DIGITAL EFFECT section. The ON switch indicator lights up. 2 Select one of eight effect types, then press the switch.
Front and rear panel 9 Front and rear panel Control panel ■ Channel section In this section, you can adjust equalization (frequency response), volume level, effect and monitor output levels for the input signal of each channel. 1 HIGH +15 –15 2 Monitor control (MONITOR) For each channel, this controls the amount of signal that is sent to the MONITOR bus.
10 Front and rear panel ■ DIGITAL EFFECT section ■ MAIN 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 MAIN bus, the mix level of the built-in effect, and the mix level of the external input.
Front and rear panel ■ MONITOR section ■ POWER AMP section 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. D This section allows you to select the signals that will be input to the built-in two-channel power amplifier.
12 Front and rear panel ■ PHANTOM switch and indicator PHANTOM K ON OFF K PHANTOM switch and indicator This switch turns the phantom power supply on/ off for the Low-Z input jacks of channels 1–4 and MIC input jacks of channels 5–6. When the switch is turned on, the indicator lights up. Turn this switch off if you do not use it. ■ YAMAHA SPEAKER PROCESSING L ON/OFF switch This switch enables you to compensate the low range of the speakers.

There are three ways in which speakers can be connected to the EMX66M. 1 A 2 1 2 AC IN socket Connect the included power cord to this socket. Connect the plug of the power cord to an AC outlet that meets the requirements stated in the specifications in this document.
16 Installation/Connection Installation/Connection Installation The EMX66M uses a forced cooling system with intake on the bottom of the rear panel and exhaust on the top of the rear panel to avoid blocking the heated air flow. Front 15cm or less NO NO Exhaust Intake Front Connection When connecting various devices, be sure to use cables and plugs of the appropriate standard. Use dedicated speaker cables to connect the speakers to the speaker jacks.
Installation/Connection 17 ■ When the power amp select switch is set to MAIN BRIDGE • Bridge connection One 8-16Ω speaker can be connected to the BRIDGE jack.

Basic Operation 19 Basic Operation This section explains basic operation of the EMX66M. 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 EMX66M and the MASTER control of the MAIN section are turned down.
20 Example setups Example setups This section provides some ways in which the EMX66M can be used, and explains connections and operation. As a conference PA system/installed sound system Here is an example of using the EMX66M as a conference PA system or as an installed sound system.
Example setups 21 As a band PA Here is an example of using the EMX66M as a small PA for a band. 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 MON” position. If you are using an external effect, we recommend that you turn down the EFFECT RTN controls of the MAIN and MONITOR sections.
22 Example setups Sending an independent mix to the monitor speakers 1 Set the MONITOR section MASTER con√” position. trol to the “√ 2 Raise the MONITOR controls for the channels that you wish to hear from the monitor speakers. Note: The MONITOR 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.
Installing an optional rack mount kit 23 Installing an optional rack mount kit You can rack-mount the EMX66M using an optional rack mount kit (RK-88). Rack mount kit RK-88 Installing the rack mount bracket 1 Remove the carrying handle by loosening and removing four screws. • Bracket × 2 • Screw × 6 Before you rack-mount the EMX66M, make sure that sufficient ventilation will be maintained. (Never install the unit in a sealed rack.
