[. . . ] The green LED constantly displays the level of signal activity by varying in intensity. Output Meter Monitors the post-fader output signal via a ten-segment LED array. Output Fader Controls the final output signal level. Output EQ Controls the the equalization of the output mix signal through three bands, via six controls. The upper knob of each band determines the center frequency (high-1kHz-20kHz, mid300Hz-8kHz, low-40Hz, 1kHz), while the lower knob adjusts the amount of boost or cut. Rear Panel Connections Balanced Out This XLR connector carries the post-fader output signal from the associated output module. EQ IN Switch Inserts the EQ section into the output channel signal. An associated LED illuminates when the switch is down. Output Insert Send This 1/4-inch TRS balanced jack carries the send signal of the output insert loop to the external effect or signal processor. High Pass Filter Switch Inserts the High Pass Filter into the output signal. Output Insert Return This 1/4-inch TRS balanced jack accepts the return signal of the output insert loop from the external effect or signal processor. HPF Frequency Control This knob adjusts the high pass filter frequency from 20Hz to 400Hz. The filter operates at a -12 dB per octave rate. Return Level Controls Adjusts the level of return signals 1 and 2 in the output. These signals come from the Master Section. See Returns 1 & 2 on the Master Section description for more information. Sub Input Controls Adjusts the level of cross-mix in the output from mono outputs 11 and 12. Polarity Reverse Switch Inverts the polarity of the output. Insert On Switch Turns on the insert loop for the output signal. If a complete insert loop is not present depressing this switch will mute the output. TB Enable Switch Injects the talkback signal from the master section into the group output. DIM Switch Introduces a -6dB drop to the output signal. This is a push on/push off switch, not momentary. MUTE Switch with LED Mutes the output. This switch does not affect the PFL switch or the Peak and Signal Present LED indicators. Output PFL Enables Pre Fader Listening of the output signal. (this signal can be internally selected post fader) PAGE 13 FA1201 100 40 200 CENTURY SERIES OUTPUT +9 +6 +3 0 -3 -6 -9 -12 -15 -18 20 400 RETURN 4 3 2 1 0 4 3 2 1 0 10 56 7 1 8 9 10 56 7 8 9 2 5 3 10 15 SUB INPUT 4 5 6 11 3 7 2 1 0 10 5 6 12 7 8 9 0 10 4 3 2 1 1K 20K O+ 8 9 HF 8 8 16 1K 600 16 3 5 MN OO 300 O+ 8 8K MID 8 Ø 16 150 100 16 300 6 1K O+ INSERT O N 40 LF 8 TB ENB BAL OUT LEFT 8 16 16 DIM EQ IN MUTE INSERT SEND HPF 80 40 200 100 PFL PEAK 20 400 INSERT RETURN SIG RETURN 4 3 2 1 0 4 3 2 1 0 10 56 7 1 5 BAL OUT RIGHT 8 9 10 56 7 8 9 0 2 INSERT SEND 5 10 SUB INPUT 4 5 6 11 3 7 2 1 0 4 3 2 1 0 10 INSERT RETURN 20 8 9 10 5 6 12 7 8 9 30 40 MN OO Ø PAGE 14 CENTURY SERIES FA1201-8+4 Output Module The FA1201-Stereo group output module is the primary output module on the discontinued FA1201-8+4. FA1201 MUTE Switch with LED Mutes the output. This switch does not affect the PFL switch or the Peak and Signal Present LED indicators. Output Meters Monitors the post-fader output signal via two ten-segment LED arrays. Output PFL Enables Pre Fader Listening of the output signal. If a complete insert loop is not present depressing this switch will mute the output. TB Enable Switch Injects the talkback signal from the master section into the group output. DIM Switch Introduces a -6dB drop to the output signal. This is a push on/push off switch, not momentary. MUTE Switch with LED Mutes the output.

FA1201 Output 11 Talkback Enable Injects the talkback signal from the master section into the group output. Output Meter Monitors the post-fader output signal of group 11 via a tensegment LED array. Output 11 Dim Switch Introduces a -6dB drop to the output signal. This is a push on/push off switch, not momentary. Monitor Level A Adjusts the output level of local monitors A. Output 11 Mute Switch Mutes the output. This switch does not affect the PFL switch or the Peak and Signal Present LED indicators. Monitor Mute A Mutes local monitor A. Output 11 PFL Switch Enables Pre Fader Listening of the output signal. (This can be internally selected to post fader) Sub 11 Post Switch Switches the subgroup send between pre and post fader. Sub 11 On Switch Switches the subgroup send on and off. Output 11 Peak & Signal LEDs The red LED indicates that the output is within 3dB of the clipping point. The green LED constantly displays the level of signal activity by varying in intensity. Lamp Dim Control Controls the brightness of any 12 volt lighting devices attached to the XLR connectors on the light bar. Output 11 100mm Faders Controls the final signal level of outputs 11. Power Indicators Shows the status of the four voltages used by the console. Rear Panel Connections Output 11 Bal Out This XLR connector carries the post-fader output signal from the output group 11 Phantom Master Switch w/LED Switches +48V phantom power on and off for the entire console. Insert Send This 1/4-inch TRS balanced jack carries the send signal of the output insert loop to the external effect or signal processor. Input/Output PFL Indicators These LEDs indicate what type of signal (input or output) is PFL'd at any given time. Input PFL always gets priority over output PFL. Insert Return This 1/4-inch TRS balanced jack accepts the return signal of the output insert loop from the external effect or signal processor. Input Fader Mix Switch Sums all input mixes and assigns the summed signal to the Monitor A output. This output is stereo when stereo signals are present. This signal is post fader. Monitor A Out (L&R) These two connectors deliver local monitor A `s balanced output signal. Return Master Peak & Signal LEDs The red LED indicates that the output is within 3dB of the clipping point. [. . . ] The internal 1kHz oscillator is defeated when a plug inserted. LINE Switch Selects the input signal source between the Balanced XLR Microphone Input connector and the Balanced Line Input 1/4" TRS connector. Output Insert - See Insert Output EQ - See Equalizer Controls (Output) Line Input This jack accepts balanced and unbalanced line level inputs and delivers it into the associated input channel. PAD Switch Introduces a -15 dB drop to the mic input signal. Microphone Input This connector accepts balanced microphone inputs for the associated input channel. PEAK LED Indicator Illuminates RED when any of the points monitored come within 3db of the clipping point. Signal is sampled after the input preamplifier stage, after the EQ section, and after the fader. This LED also serves as a PFL ON indicator, but at a much lower intensity than when it is used to indicate clipping. Microphone Output This connector is in parallel with the Balanced Mic In connector and allows easy connection of the monitor board to the FOH console. PFL Indicator This LED illuminates when the signal on meter 12 is a PFL or AFL signal Mix Sends Every FA1201 console has twelve (12) send controls. Each FA1201 model deals with these twelve controls differently: FA1201-12 · Each of the twelve knobs determine the amount of signal sent to each of the twelve outputs. [. . . ]
