YAMAHA MC-Series Mixing Consoles Operating Manual
Congratulations! You are the proud owner of a Yamaha MC-series Mixing Console. Whether you chose the 8, 12 or 16-channel model, your Yamaha mixing console is a high-quality product that will give you superior performance in a wide range of applications.
PRECAUTIONS 1. AVOID EXCESSIVE HEAT, HUMIDITY, DUST AND VIBRATION Keep the unit away from locations where it is likely to be exposed to high temperatures or humidity–such as near radiators, stoves, etc. Also avoid locations which are subject to excessive dust accumulation or vibration which. could cause mechanical damage. 2. AVOID PHYSICAL SHOCKS Strong physical shocks to the unit can cause damage. Handle it with care. 3. DO NOT OPEN THE UNIT OR ATTEMPT REPAIRS OR MODIFICATIONS YOURSELF 5.
FRONT PANEL CONTROLS Input Channels PAD Switch This switch attenuates the signal applied to the corresponding rear-panel HI-Z or LO-Z input by 20 dB prior to the head amplifier and input gain control. The PAD switch effectively increases the range of input signal levels that can be handled by the mixer, preventing overloading of the input circuitry when receiving high-level signals. GAIN Control This control adjusts the input sensitivity of each input channel between –60 dB (0.775 mV) and –20 dB (77.
AUX Controls (1,2 & 3) The MC-series mixing consoles have three independent AUX busses which are fed by the corresponding AUX controls on the input channels. Each AUX control determines the level of the signal sent from that channel to the correspondingly numbered AUX mixing buss, which in turn feeds the correspondingly numbered AUX SEND control and AUX SEND jack on the console’s rear panel.
Channel Fader This is the main level control for each input channel. It determines the level of the signal sent from the corresponding input channel to the master stereo buss. The settings of the input channel faders determine the "mix" or balance of sound levels between the instruments or other sources connected to the inputs. * If a channel is not being used, its fader should be set to the minimum position to prevent unwanted noise from being added to the main program signal.
Master Control Section AUX SEND (1, 2 & 3) Controls & CUE Switches These adjust the overall output level of the auxiliary "mixes" set up using the AUX 1, AUX 2 and AUX 3 controls on the input channels. AUX SEND 1 sets the overall level of the AUX 1 mix signal appearing at the AUX SEND 1 jack, AUX SEND 2 sets the overall level of the AUX 2 mix signal appearing at the AUX SEND 2 jack, and AUX SEND 3 sets the overall level of the AUX 3 mix appearing at the AUX SEND 3 jack.
Talkback ON Switch Pressing this switch activates the talkback microphone plugged into the talkback mic connector, allowing voice communication from the console operator to the STEREO, AUX 1, AUX 2 or AUX 3 busses according to the setting of the talkback assignment switches. TB (Talkback) Level Control Adjusts the level of the talkback signal sent to the selected buss. Talkback Microphone Connector This female XLR type connector accepts just about any standard 50 ~ 600 ohm microphone for talkback pickup.
VU Meters and METER Assign Switches (AUX1/AUX2/AUX3/CUE) The MC-series mixing console feature three VU meters with built-in LED peak indicators for monitoring signal levels. The rightmost meter pair (L ST R) continuously monitors signals on the main stereo program buss. The AUX/CUE meter can be switched to monitor signals on the AUX 1, AUX 2, AUX 3 or CUE busses by pressing the corresponding METER assign switch.
STEREO Master Faders The STEREO master faders independently adjust the level of the left and right channel main stereo program buss signals appearing at the STEREO OUT connectors.
POWER Switch Flip up to turn power ON, and down to turn power OFF. The VU meter lamps will light when the power is ON. PHANTOM MASTER Switch Turn this switch ON to apply +48 volts DC to the LO-Z XLR input connectors when using phantom-powered condenser microphones. * NEVER turn the PHANTOM MASTER switch ON when applying line-sources to the LO-Z inputs.
APPLICATION EXAMPLE In the system shown below the MC1602 is used as the main console in a sound reinforcement system. Three vocal microphones, six drum microphones, a microphone from the guitar amplifier and another from the bass amplifier are connected to 11 of the 16 available LO-Z inputs. The line-level stereo outputs from an on-stage keyboard mixer and the stereo outputs from an electronic percussion system are fed to four HI-Z inputs.
