Their broad versatility and plentiful complement of control features make them ideal for sound reinforcement, recording, theater and production applications. Further, state-of-the-art design and technology has made it possible to offer such exceptional flexibility and performance at significantly reduced cost. Your MC-series mixer should provide you with years of trouble-free performance. To make the most of all the features and performance it provides, however, we recommend that you read this operating manual thoroughly before use.

The PAD switch inserts a 20 dB pad ahead of the head amplifier, and the GAIN control continuously adjusts the sensitivity of the head amplifier between - 20 and - 60 dB. The PEAK LED lights whenever the channel’s post-EQ, pre-fader signal comes within 3 dB of clipping, warning the operator of impending channel overload. 0 HIGH, MID FREQ/MID and LOW EQ controls These continuously variable controls allow ± 15 dB of equalization in the following frequency ranges: HIGH.................................................................................10 kHz shelving. MID/FREQUENCY..............................................................350 Hz—5 kHz peaking. LOW..................................................................................100 Hz shelving. Response is flat at the center position. busses which feed the FB 1 and FB 2 outputs, respectively. These busses would normally be used for stage foldback or monitor speaker systems. Internal P.C. board jumpers are provided for changing the foldbacks to post EQ and fader for use as additional echo/effect sends. This modification can be made at any Yamaha Service Center. Post fnsert I/O Pre EQ Post EQ Pre Fader Post Fader FB 1.2 FACTORY SET O O ECHO 1.2 O O FACTORY SET O ECHO 1 and ECHO 2 controls Adjusts the amount of post-EQ, post-fader signal fed from that channel to the ECHO 1 and ECHO 2 busses, which feed the ECHO 1 and ECHO 2 outputs, respectively. The echo busses may be used to feed outboard effect devices or as additional foldback/monitor sends. 2 0 PAN control and Group 1-2/3-4 Assignment Switches The PAN control assigns the channel fader output to group busses 1 -2 and/or 3-4 according to the setting of the buss assignment switches. When group assignment switch 1 -2 is engaged, the signal is panned between busses 1 and 2. If 3-4 is engaged the signal is panned between busses 3 and 4. Both switches can be engaged, in which case the signal is panned between group busses 1 -3 and 2-4. Panning left delivers more signal to busses 1 and 3, while panning right delivers more signal to busses 2 and 4. © CUE button Pressing the CUE button on any channel permits monitoring of only the selected channel signal via the headphone output. All other outputs are not affected. If more than one channel is “cued”, their signals are summed and fed to the headphone output. O CH ON button The CH ON button turns the respective channel ON or OFF. This is handy for rapid punch-ins or punch-outs, or for temporarily killing a channel without disturbing the mix fader level. Q Channel Fader These set the mix level of each channel. These smooth linear faders also provide a good visual indication of the overall mix levels. Rated output (nominal) level is achieved with the fader set at “6” ( ► -4 ) on the scale. 448V 3 Echo Return and Group Out Sections 0 * 10 ECHO RETURN 1 □ GROUP 1 O Echo PAN control and 1-2/3-4/S...
