35、d (follow mute is default). mono input module monitor features 8-segment channel meter Monitors a pre or post fader signal level as determined by a Master Global POST switch within the master section of the console. Normally, a pre fader signal is monitored. When the Global master switch is depresse

36、d,ALL channel meters switch to a post fader monitor position to prevent confusion between pre and post channel metering. The 8 seg- ments include a dynamic signal present LED indicator which varies in intensity to indicate the presence of any audio signal, and increases in intensity until it reaches

37、 full brightness. When signal level reaches -15dB, an additional LED will illuminate. Additional LEDs indicate at channel sig- nal levels of -6dB,-3dB,0dB,+3dB and +8dB. The top red segment samples signals at a pre EQ position,post EQ posi- tion,and a post fader position. When any of these points ap

38、proach 3dB of clipping,this led will illuminate RED. This LED is NOT affected by the posi- tion of the Global Post Fader monitor switch. VCA-level LED This LED glows green to indicate the amount of control voltage applied to the channel VCA; the greater the control voltage, the brighter the LED. Oft

39、en,a channel may be assigned to more than one VCA master,and it is easy to overlook an assignment and wonder why a channel isnt on.This LED gives the operator a quick reference to the state of the channel VCA; if there is no LED indication,there is no VCA control voltage.The LED will turn from green

40、 to red when the control voltage limit of +20dB is reached as detailed above.This alerts the operator to unusual or incorrect gain set- tings and prevents any additional fader boost from being applied. solo switch Will illuminate when manually selected in one of the consoles many Solo modes. Control

41、s within the master section determine if this switch will sample signal pre fader or post fader/post pan pot. Additional switches will determine the operating characteristics of the Solo system. These may be selected from within the master section to be NORMAL (cumulative), LAST PRESSED (Only one sw

This Solo switch will also Solo and illuminate automatically if the VCA master group that the channel may be assigned to is put i

43、nto SOLO. The SOLO system displays selected channels on individual Solo Left and Solo Right meters. The signal also appears on separate Headphone and Monitor output channels. The solo signal may also be routed to the Alternate A/B and C/D outputs within the master section. write-on strip In the area
