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.
6 EMX88S/EMX68S Quick Guide EMX88S/EMX68S Quick Guide Never connect the speakers in the manner shown below. Otherwise, the EMX88S/EMX68S’s builtin power amplifier will be damaged. The following steps (1–5) explain the basic connection and operation of the EMX88S/EMX68S. Also, please read “Front and Rear Panel” and “Basic Operation” following this Quick Guide section to learn more about using the EMX88S/ EMX68S.
EMX88S/EMX68S Quick Guide Connecting a microphone Make sure that the power is turned off to the EMX88S/EMX68S. Connect a microphone to the Low-Z jack or MIC jack. 7 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 EMX88S/EMX68S Quick Guide Connecting an electric acoustic guitar or electric bass Connect an electric acoustic guitar or electric bass to the Super Hi-Z jacks. If you wish to connect multiple instruments, make a monaural connection as shown below. EMX88S (EMX68S) EMX88S (EMX68S) Electric-acoustic guitar Electric bass • If you wish to use a guitar signal processor or bass effect unit, connect them to the Hi-Z jack or LINE jack.
EMX88S/EMX68S Quick Guide STEP 3 Sound output Set the MASTER control in the MAIN section to “√ ,” then while playing an instrument connected to a channel to be checked (or while speaking to a connected microphone), adjust the LEVEL control of the corresponding channel so that the 0 LED of the peak level indicator in the MAIN section will light up momentarily. • Do not press the PAD switch if sound is input from the microphone. Otherwise, press the PAD switch on.
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).
Control panel ■ DIGITAL EFFECT section This section allows you to turn the built-in digital effect on/off and to select the effect type. 11 val between the last two presses will be set as the delay time. The specified time will be remembered even if the power is turned off. The LED beside the switch will blink in synchronization with the delay time only when the effect type is TAP DELAY.
12 Front and rear panel D 2TR IN control This adjusts the amount of signal that is sent from the 2TR IN jacks to the stereo (MAIN L, R) bus. These graphic equalizer settings affect both the MONITOR bus signal output to the speakers and the line level signal sent from MONITOR jack signal (input/output panel 7). H EFFECT RTN control E MASTER control This control adjusts the stereo (MAIN L, R) bus signal output level.
Control panel ■ POWER AMP section Here you can select the operating mode of the power amp. You can also check the operation of the limiter circuit. M 13 ■ YAMAHA SPEAKER PROCESSING O ON/OFF switch This switch enables you to compensate the low range of the speakers. The low range balance when this switch is on varies depending on the speakers. First, check the low range balance by auditioning the resultant sound, then set this switch to on or off.
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).
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.
