Reference Front & Rear Panels 6 GAIN Control Adjusts the input signal level. To achieve the best balance between S/N ratio and dynamic range, adjust the level so that the PEAK indicator 9 lights only occasionally and briefly on the highest input transients. The -60 to -16 scale is the MIC input adjustment range. The -34 to +10 scale is the LINE input adjustment range. 7 Switch (High Pass Filter) This switch toggles the HPF on or off. To turn the HPF on, press the switch in ( ). The HPF cuts frequencies below 80 Hz (the HPF does not apply to the line inputs of stereo input channels 3). 8 COMP Control Adjusts the amount of compression applied to the channel. As the knob is turned to the right the compression ratio increases while the output gain is automatically adjusted accordingly. The result is smoother, more even dynamics because louder signals are attenuated while the overall level is boosted. NOTE Avoid setting the compression too high, as the higher average output level that results may lead to feedback. 9 PEAK Indicator The peak level of the post-EQ signal is detected, and the PEAK indicator lights red when the level reaches 3 dB below clipping. For XLR-equipped stereo input channels (5/ 6 and 7/8), both the post-EQ and post-mic-amp peak levels are detected, and the indicator lights red if either of these levels reaches 3 dB below clipping. 0 Equalizer (HIGH, MID, and LOW) This three-band equalizer adjusts the channel's high, mid, and low frequency bands. Channels 9/10 and 11/12 have two bands: high and low. Setting the knob to the ▼ position produces a flat response in the corresponding band. Turning the knob to the right boosts the corresponding frequency band, while turning to the left attenuates the band. The following table shows the EQ type, frequency, and maximum cut/boost for each of the three bands. Band HIGH MID LOW Type Shelving Peaking Shelving Frequency 10 kHz 2.5 kHz 100 Hz Maximum Cut/Boost ±15 dB A AUX (AUX1) Control Adjusts the level of the signal sent from the channel to the AUX (AUX1) bus. The knob should generally be set close to the ▼ position. On stereo channels, the signals from the L (odd) and R (even) channels are mixed and sent to the AUX (AUX1) bus. NOTE To send the signal to the buses set the ON switch to on ( ). B AUX PRE Switch Selects whether the pre-fader or the post-fader signal is fed to the AUX (AUX1) bus. If the switch is on ( ), the mixer sends the pre-fader signal (the signal immediately prior to the Channel fader I) to the AUX (AUX1) bus, so that AUX (AUX1) output is not affected by the fader. If the switch is off ( ) the mixer sends the post-fader signal to the AUX (AUX1) bus. C EFFECT (AUX2) Controls Adjusts the level of the signal sent from the channel to the EFFECT (AUX2) bus. Note that the signal level sent to the bus is also affected by the Channel fader I. On stereo channels (5/6, 7/8, 9/10, or 11/12), the signals from the L (odd) and R (even) channels are mixed and then sent to the EFFECT (AUX2) bus. D PAN Control (1 to 4) PAN/BAL Control (5/6 and 7/8) BAL Control (9/10 and 11/12) The PAN control determines the stereo positioning of the channel signal on the REC L and R buses or on the Stereo L and R buses. The BAL control knob sets the balance between left and right channels. Signals input to the L input (odd channel) go to the REC L bus or to the Stereo L bus; signals input to the R input (even channel) go to the REC R bus or the Stereo R bus. NOTE On channels where this knob provides both PAN and BAL control (channels 5/6 and 7/8), the knob operates as a PAN control when input is received via the MIC jack or L (MONO) input only, and as a BAL control when input is received via both L and R inputs. E ON Switch Turn this switch on to send the signal to the buses. The switch lights orange when on. F PFL (Pre-Fader Listen) Switch This switch lets you monitor the channel's pre-fader signal. Press the switch in ( ) so that it lights to turn it on. When the switch is on the channel pre-fader I signal is output to the PHONES and MONITOR OUT jacks for monitoring. G REC Switch This switch assigns the channel's signal to the REC L and R buses. NOTE To send the signal to the REC bus engage the ON switch ( ). H ST Switch This switch assigns the channel's signal to the Stereo L and R buses. NOTE To send the signal to the Stereo bus engage the ON switch ( ). I Channel Fader Adjusts the level of the channel signal. Use these faders to adjust the balance between the various channels. NOTE Set the fader sliders for unused channels all the way down to minimize noise. MW12CX/MW12C Owner's Manual 17
