User manual RANE CM 86

[. . . ] When using the AUX A/B level controls, remember to set the desired take-off location using the PRE/POST switches. PRE takes this signal before the Channel LEVEL controls, allowing independent operation of both. POST takes this signal after the Channel LEVEL controls, allowing the LEVEL controls to turn the Aux levels up/down simultaneously. Set the OUTPUT SELECT to assign each input channel to the desired output. [. . . ] Selecting POST takes the AUX Level after the Channel LEVEL controls, thereby allowing the LEVEL controls to affect all outputs. Separate controls for mixing the input channel into the AUX A and AUX B Output (Send) signals. A three-position slide switch that selects routing of this input channel. Choosing either "A" or "B" puts all of this signal into only the A or B outputs. Concentric controls used to set the amount of signal mixed into the MASTER A and B outputs. Three rotary controls that set the amount of the Tape, Tuner, or CD input signals mixed in with the AUX A, AUX B or MASTER outputs. Concentric knobs that control the amount of AUX signal coming into the AUX OUT/IN jacks (on the ring). Often the return path from an effects box in the AUX OUT/IN LOOP; or alternatively, it may control a separate AUX input. Concentric knobs that control the amount of AUX signal coming out of the AUX OUT/IN jacks (on the tip). Often the send path for an effect box in the AUX OUT/IN LOOP; or alternatively, it is the AUX output level. LED indicators monitoring the four critical summing stages (Master A/B and Aux A/B). A three-position slide switch used to choose between MASTER 1A/1B, MASTER 2A/2B or AUX A/B outputs for monitoring by the OUTPUT METERS and HEADPHONE circuits. A yellow LED that lights whenever proper power is applied to the CM 86. Standard wiring convention is followed, i. e. , Tip=Left ear= Channel A, and Ring=Right ear=Channel B. A two-channel 6-segment peak responding LED meter accurately calibrated in dBu units. REAR PANEL DESCRIPTION 1. This red LED is identical to one on the front panel and monitors all critical input nodes. A rotary control used to set the correct gain required by your microphone. Pin 2 is positive, pin 3 is negative and pin 1 is signal and shield ground. This jack allows any outboard unit to be patched in-series with the input signal. A pair of UNBALANCED 1/4" TRS jacks used for either AUX OUT alone, or as a Send/Receive (Out/In) effects loop for recording and other applications. [. . . ] The unbalanced TAPE OUT RCA jacks should be treated similarly, i. e. , restrict their IMPORTANT NOTE CHASSIS GROUNDING The CM 86 is supplied with a rear mounted LIFT (ground-lift) switch. The Flex Bus allows you to expand the CM 86 using either another CM 86 or any of the Flex bus modules. The bus carries four signal lines (Master A & B and Aux A & B) and two spare. The signal lines come into the CM 86 via the FLEX BUS IN connector, sum with all local inputs and exit via the FLEX BUS OUT connector. [. . . ]
