FRONT PANEL CONTROLS 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

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. The AUX controls can be used to determine the amount of signal from the corresponding input channel sent

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. 5

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 con- trols 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. These controls should b

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 talkbac

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. CUE/PHONES Control and PHONES Jack The CUE/PHONES control adjusts the level of the
