If the channel Fader is set at -10 dB, and is assigned to two VCA Masters, each set at -10 dB, then the channel level will be -30 dB (-10 + (-10) + (-10) = -30). If the channel Fader is set at +10 dB, and is assigned to two VCA Masters, one of which is set at +10 dB, and the other at -20 dB, then the channel level will be 0 dB (+10 + (+10) + (-20) = 0). When an input Fader or an assigned VCA Master Fader is pulled all the way down to “infinite” attenuation position, the voltage is sensed in the input module, and the channel on/off relay opens to completely kill the output from the VCA. The channel ON lamp will remain active, however, indicating that any pre-fader channel outputs are still “live." If the console is set to the “SLAVE” rather than the “MASTER” mode with the rear-panel VCA SLAVE/ MASTER switch [111], then the console’s VCA MASTER Faders will have no effect. Instead, any DC control signals applied to the VCA/MUTE CONTROL connector [129] will affect correspondingly assigned input channels. Page 2-16 The Stereo Master Module This module controls the output of the stereo bus and the two aux stereo busses. Figure 2-4a. PM4000 Stereo Master Module (upper portion of module) AUX 2 STEREO SEND MASTER SECTION 48. BAL/LEVEL R and LEVEL/LEVEL L (rotary controls) This pair of rotary controls’ functions depends on the setting of the BAL/LEVEL switch [49]. With the switch disengaged (not illuminated), the upper control serves as a balance control, increasing the level in the left in the left output and decreasing the right output level of the Aux 1 stereo output as the control is rotated counterclockwise from center, or vice-versa as it is rotated clockwise front center position. The lower control then serves as a master level control that simultaneously affects both sides of the Aux 1 stereo output With the switch engaged (illuminated), the upper control serves as a master level control for the mono signal feeding the Aux 1 Right output connector, and the lower one as the master level control for the Aux 1 Left output connector. 49. BAL/LEVEL (locking switch) This switch determines whether the pair of rotary controls above and below it serve as separate level controls for the Aux 1 left and right outputs (switch engaged and illuminated) or as balance and level controls for the Aux 1 outputs (switch up, LED off). 50. INSERT (Aux 1 Stereo insert) The Aux 1 Stereo output circuit has a pair of insert Out/In patch points (L & R) located just before its master level and balance controls. The OUT jacks are always active. If this switch is engaged (LED illuminated), the L & R IN jacks become active. Thus, engaging the INSERT switch can insert a stereo signal processor (or a pair of mono processors) in the aux channel, or it can substitute an external line-level input instead of the mixed aux signals. NOTE: The Aux Stereo Sub In jacks apply signal to the aux mix ahead of the insert point, so aux sub-in program will be fed to the aux insert out jacks. 51. CUE (Aux 1 Stereo cue) Pressing this switch part-way down causes momentary contact; pressing it further locks it down. When the CUE switch is illuminated, the aux 1 master cue mix signal (post insert point, pre master control) replaces any other signal in the Cue output and the Phones output unless an input CUE switch is engaged. (Bus cue signals are overriden by input cue.) The aux 1 stereo cue signal is stereo. Page 2-17 ON (Aux 1Master On) Engaging this locking, illuminated switch turns on the Aux 1 master output. When the output is turned off, the feed to the VU meter is also off, although the signal may still be previewed with the adjacent CUE switch [51]. 53. AUX 2 STEREO SEND MASTER SECTION This cluster of controls and switches functions identically to the Aux 1 Stereo Send Master Section [48-52], except they affect the Aux 2 Stereo Output. Figure 2-4b. PM4000 Stereo Master Module (lower portion of module) STEREO MASTER SECTION 54. STEREO-TO-MTRX Engaging this locking switch assigns signal from the Stereo Output (ahead of the Stereo ON switch) to all L and R rotary mix controls in the matrix. The switch is illuminated when the stereo signal is assigned to the matrix. NOTE: The signal is routed to the matrix via an internal switch in the module. The switch is preset so the feed to the matrix comes after the Stereo Master Fader; the switch may be moved to obtain a pre-Stereo Master Fader feed. Refer to Section 6 for more information on this optional function. 55. INSERT (Stereo master insert) The Stereo master output circuit has a pair of insert Out/In patch points (L & R) located just before the master faders. The OUT jacks are always active. If this switch is engaged (LED illuminated), the L & R IN jacks become active. Thus, engaging the INSERT switch can insert a stereo signal processor (or a pair of mono processors) in the stereo master output, or it can substitute an external line-level input instead of the mixed stereo signals. NOTE: The Stereo Sub In jack...
