User manual RANE FPM 42

[. . . ] Set the A and B LEVEL controls on each input for the desired level. The MASTER A/B output level controls affect only the signal level at the direct outputs of the unit. They have no affect on the main output added to the BUS OUT. NEVER CONNECT ANYTHING EXCEPT AN APPROVED RANE POWER SUPPLY TO THE RED THING THAT LOOKS LIKE A TELEPHONE JACK ON THE REAR OF THE UNIT. [. . . ] The Aux source is selected from either pre- or post fade via internally located switches. 4. OVERLOAD INDICATOR This red LED comes on anytime the input amplifier exceeds a level of 4 dB below clipping. 5. These concentric knobs set the signal output level of the Master A output (inner knob) and the Master B output (outer knob). Their range is from Off to +10 dB. 6. Indicates power, as indicated. REAR PANEL DESCRIPTION 1. Use these 3-pin connectors for either microphone or line level inputs. Connect balanced sources to pin 2 ("+"), pin 3 ("­") and pin 1 (GND) terminals. Unbalanced inputs connect only to pin 2 ("+") and pin 1 (GND). When an unbalanced input is used, pin 3 ("­") may be left open or shorted to GND. If balanced operation is your choice, use both jacks as indicated by the graphics printed to the right (or top) of the jacks. One is MASTER A output, and the other is MASTER B output. These are optional unbalanced outputs programmed by changing jumpers inside the unit. Refer to the graphics found to the left (or bottom) of the jacks, and to the silkscreened word "AUX" found on the printed circuit board. Lift the jumper header up and reposition one pin over and slide back down (covering the word "AUX"). FLEX BUS IN CONNECTOR This input accepts bus information from other FLEX mixer modules, such as an FM1 14, FMM 42 or another FPM 42. This input adds to the program material connected to the FPM 42. The combined results appear at the FLEX BUS OUT jack, as well as the terminal strip outputs. FLEX BUS OUT CONNECTOR This seven-pin DIN connector provides output to other mixer modules, such as another FPM 42, an FMI 14 or an FMM 42. Signals present here include the AUX of both this FPM 42 as well as any AUX sends generated by other FLEX mixer modules connected to the FLEX BUS IN above. The Master A and B signals are also available, which are the sum of this module and any other modules connected to the bus input. Slide switches located inside the FPM 42. Used to select Aux source to be PRE- or POST- input LEVEL A/B controls. [. . . ] For further system connection possibilities, please refer to the Flex Users Guide. As noted elsewhere in this manual, NEVER USE A POWER SUPPLY WITH YOUR FPM 42 OTHER THAN THE ONE SUPPLIED FROM THE FACTORY OR AN EXACT REPLACEMENT OBTAINED FROM RANE CORPORATION. This unit's power supply input is designed for an AC supply, delivering 18-24 volts, from a center-tapped transformer capable of supplying at least the current demanded by this product. Using any other type of supply may damage the unit and void the warranty (which at two years parts and labor is worth safeguarding, don't you think?). IMPORTANT NOTE CHASSIS GROUNDING Rane Flex Series modules are supplied with either a rear, or a bottom/side mounted ground-lift switch. [. . . ]
