[. . . ] The rate of deterioration depends on the operating environment and is unavoidable. Consult your dealer about replacing defective components. MX12/6, 20/6 -- Owner's Manual 2 Front & Rear Panels Front & Rear Panels Channel Control Section Channels 1-8 (MX12/6) 1-16 (MX20/6) (Monaural) Channels 9-12 (MX12/6) 17-20 (MX20/6) (Stereo) q GAIN Control Adjusts the input level of the signal entering the mixer to an optimum level. To obtain an optimum balance between the S/N ratio and dynamic range, adjust the level so that the peak indicator w occasionally lights. -60 to -16 indicates the MIC input adjustment level, -34 to +10 indicates the LINE input adjustment level. q w w PEAK Indicator e The indicator detects peaks in the signal after it has passed the EQ. The indicator will light red when the level reaches +17dB to warn that clipping is imminent. e Equalizer r r t t Provides +/-15dB of control over high, mid and low frequency ranges at the center frequencies listed below. HIGH : 10kHz (shelving) MID : 2. 5 kHz (peaking) LOW : 100Hz (shelving) Frequency response will be flat when the knob is positioned at "G". +20 +15 y u Response [dB] +10 +5 0 ­5 ­10 ­15 ­20 20 100 1k Frequency [Hz] 10k 20k i i r AUX1, AUX2 Controls t POST Switch o Individually controls the level of the signal sent from each channel to the AUX1 and AUX2 buses. The signal taken from before the channel fader is sent to AUX1. Depending upon the POST switch setting, the signal taken from either before (POST Switch = ?) or after (POST Switch = >) the channel fader is sent to AUX2. When a stereo channel is used, L and R signals are combined and sent to the AUX1 and AUX2 buses. The MX12/6's panel is used for all following illustrations in this manual. MX12/6, 20/6 -- Owner's Manual Front & Rear Panels 3 y EFFECT Control Controls the level of the signal sent from each channel to the EFFECT bus. This control is located after the channel fader so its level will also be affected by the channel fader setting. When a stereo channel is used, L and R channel signals are combined and sent to the EFFECT bus. u PAN Control (MX12/6:CH1-8, MX20/6:CH1-16) BAL Control (MX12/6:CH9-12, MX20/6:CH17-20) The PAN control knobs set the position within the stereo field of each signal that is sent to the GROUP bus 1-2, GROUP bus 3-4 and STEREO bus L-R. The BAL control knobs set the balance between left and right channels and assigns the signals that are received at INPUT L (MX12/6:CH9, 11, MX20/6:CH17, 19) to GROUP buses 1/3 or STEREO bus L, and the signals received at INPUT R (MX12/6:CH10, 12, MX20/6:CH18, 20) to GROUP buses 2/4 or STEREO bus R. i GROUP, ST Select Switches Used to send the signal of each channel to the GROUP bus 1-2, GROUP bus 3-4 and STEREO bus L-R. A +/-12dB boost or cut is provided at each of the frequency bands 125, 250, 500, 1k, 2k, 4k and 8kHz. !0 C-R/PHONES Output and Meter Select Switch Selects the signal that is sent to the C-R/PHONES jack and the level meter. The three switches are used in combination to select TAPE IN, ST, GROUP 1-2 and GROUP 3-4 signals. Signal TAPE IN ST GROUP 1-2 GROUP 3-4 ?? !1 C-R/PHONES Control Controls the level of the signal that is sent to the C-R/PHONES jack. !2 LEVEL Meter The LEDs indicate the output level of the signal selected with the C-R/PHONES output and Meter Select Switch !0. "0" indicates a nominal level, and the PEAK indicator will light when clipping is imminent. !3 POWER Indicator The indicator will light when the main unit's power is ON. !4 LAMP Connector A BNC type lamp (AC or DC12V, 0. 5A Max) can be attached here. Refer to the Block Diagram on page 13. MX12/6, 20/6 -- Owner's Manual 6 Front & Rear Panels Connector Section e q w r t q INPUT Jacks (MX12/6:CH1-8, MX20/6:CH1-16) · MIC · LINE Balanced XLR type microphone input jacks (1:Ground, 2:Hot, 3:Cold). These input jacks are compatible with 50-600 microphones. Balanced TRS phone type line input jacks (T:Hot, R:Cold, S:Ground). These input jacks are compatible with 600 line level devices. Unbalanced phone plugs can be connected but noise may enter the signal if the cables are too long or if the location is susceptible to electromagnetic interference. NOTE: It is not possible to simultaneously use both the MIC INPUT jack and the LINE INPUT jack on any individual channel. Please use only one or the other jack. w INPUT Jacks (MX12/6:CH9-12, MX20/6:CH17-20) Unbalanced phone type and RCA pin type stereo line input jacks. [. . . ] Basically, you should set the Channel Fader close to the "0" position. <Recording> q Select the channels you want to record to the computer by pressing their "3-4" GROUP Select Switches. Also, select the channels you want to monitor by pressing their "1-2" GROUP Select Switches. * w Use the GROUP 3, 4 Faders to adjust the level of the signal sent to the computer. * Do not press the "3-4" GROUP Select Switches on the channels that carry the signal from the computer. Doing so will result in a loop which may cause feedback. <Mix Down> q Select the channels you want to send to the master recorder by pressing their GROUP Select Switches ST. Also, select the channels you want to simultaneously monitor by pressing their GROUP Select Switches 1-2. [. . . ]
