User manual CREST AUDIO LM

[. . . ] CENTURY SERIES LM OWNER'S MANUAL Congratulations on your purchase of a Century Series console. All of us at Crest Audio in Paramus, New Jersey, USA, support your decision, knowing your console contains the finest combination of design and manufacture in the industry. While your new Century Series console is one of the most feature-packed available, great effort has been put into making it simple to operate. This manual explains the functions of your new console, how they operate and how they relate to each other. [. . . ] 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. (this send can be internally selected post fader) 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. Output 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. EQ IN Switch Inserts the EQ section into the output channel signal. An associated LED illuminates when the switch is down. Output Fader Controls the final output signal level High Pass Filter Switch Inserts the High Pass Filter into the output signal. Rear Panel Connections (L & R) Balanced Out This XLR connector carries the post-fader output signal from the associated output module. 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. 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. Return Level Controls Adjusts the level of return signals 1 and 2 in the output. These signals come from the Master Section. The center knob adjusts level while the outer knob adjusts panning within the stereo image. See Returns 1 & 2 on the Master Section description for more information. 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. Sub Input Controls Adjusts the level of cross-mix in the output from mono outputs 11 and 12. The center knob adjusts while the outer knob adjusts panning within the stereo image. Mono Switch Depressing this switch mixes the left and right pre-insert signals together onto the Left Insert Send jack. The Left Insert Return is switched to both Left and Right Returns. This allows for a mono processor to be used, but affect both channels. 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.

LM Output 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. Output Meter Monitors the post-fader output signal via two ten-segment LED arrays. 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 gain or cut. This single set of knobs controls both channels A & B. Output Faders Controls the final output level of each signal (a & b). Rear Panel Connections (L & R) 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. This single knob controls both channels A & B. Return Level Controls Adjusts the level of return signals 1 and 2 in the output. These signals come from the Master Section. The center knob adjusts "level A" while the outer knob adjusts "level B. " 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. [. . . ] LM-8+4 · The first eight controls are dual concentric and they determine the amount of signal sent to the first eight stereo outputs. The center knob controls level while the outer knob is a PAN control. The last four knobs adjust the level of signal sent to outputs 9-12. LM-20 · The first eight controls are dual concentric and they determine the amount of signal sent to the first sixteen outputs (1a/1b . [. . . ]
