It is equipped with a graphic equalizer, reverberation unit and monitor circuit which extend the mixer's application range from ordinary public address (PA) to business use. Please read this instruction manual carefully before you start to use it so that you can obtain its long life and best possible service.

When wiring, please refer to p. 5 for correct connections and make sure that the power switch is set to OFF. • As to the speaker impedance, the acceptable speaker load is from 8 to 16 ohms for USA and Canadian models and from 4 to 16 for general models. Do not connect a speaker system with a total impedance of less than 8 ohms in case of USA and Canadian models and 4 in case of general models. • Do not set the controls to the following positions. INPUT LEVEL controls —50 for all channels Channel controls Max. for all channels LOW-EQ, HIGH-EQ controls Max. for all channels GRAPHIC EQUALIZER Max. for each frequency PROGRAM master controls Max. Although any of the above settings can't be expected in ndrmal use, please remember that if you inadvertently set the controls to the positions given above and if it coincides with certain conditions of the equipment connected to the input connectors or the load speakers, oscillation may occur and result in damage to the speakers. • When the power switch is set to ON, it takes a few seconds before anything is heard from speakers. This is simply because the circuit to control the speakers is at work to prevent the shock noise at the time of turning the switch to ON and OFF, and therefore is not any trouble at all. • Clean panels etc. with a soft dry cloth only. Never use paint thinner and such, for the color of the panels may change. 1 K> BLOCK DIAGRAM CONTROL PANEL OPERATIONS ©YAMAHA • TED M------------- 1 INTEGRATED MIXER EM SERIES MODEL & 0 Ô Ô 0 0 Ô ft Ô Ô Ô Ô Ô 0 '# 0 Ô & Üfc •Ô H O n # O O B: 4XH HIF 4XF 4XP LQJJ Cs^ CH-1 CH-2 OH-3 CH-4 OH-5 CH-6 O VOLUME controls These are mixing volume controls to select the sound volume of each channel, so that volume levels are in good proportion. As to the unused channel, make sure to keep its VOLUME control set to "0". '9 © INPUT LEVEL controls These are used to select the input levels of the channels. Switch them to one of MIC, INST, and LINE in accordance with the output signal of the equipment connected to the INPUT connectors of the rear panel. Proper setting of the input levels not only prevents the overdrive of the head amplifier which causes distortion of the sound but also is the key to create a clear and agreeable sound for ears. The table below lists the general settings. Set the controls to the proper level in accordance with the intended application. INPUT LEVEL control setting Input source MIC —50dB General dynamic type microphone, condenser type microphone INST —35dB Electric or electronic musical instrument such as electric guitar LINE —20dB General audio equipment such as tape deck or tuner © LOW-EQ controls These are used to control the sound quality in the low range of each channel. The low frequency of 100Hzcan be controlled within the range of ±15dB, and a flat response can be yielded at "0" position. 3 ©e© O HIGH-EQ controls These are used to control the sound quality in the high range of each channel. The high frequency of 10kHz can be controlled within the range of ±15dB, and a flat response can be yielded at "0" position. © MONITOR 2 PRE-VOL. & EQ controls These are the MONITOR 2 channel controls and they are used to control the signal level which is fed out from the pre-stages of the channel controls and equalizer and sent to the MON OUT 2 jacks. They are also used as foldback (stage monitor) mixing controls for performers. ©MONITOR 1 (REV/ECHO) POST-VOL. & EQ controls These are the MONITOR 1 channel controls and they are used to control the signal level which is fed out from the post-stages of the channel controls and equalizer and sent to the reverberation circuit, and to each of the MON OUT 1 and ECHO SEND jacks. These controls perform the fo...
