User manual RANE FPM 44

[. . . ] OPERATING / SERVICE MANUAL QUICK START This section provides for those with limited reading patience, and/or a high level of technical expertise. It familiarizes you enough with the FPM 44 to allow operation without wading through the rest of the text. You owe it to yourself to read at least this section to ensure reasonable operation of the unit. They are to be connected to the terminal strips on the rear. [. . . ] These switches set the maximum gain of the input stages in each of the four input sections. The 60dB mode is normally used for most microphones. The 40dB mode would be used for high level microphones or very weak line level inputs. The 10dB mode is suitable for line level inputs. Phantom power is automatically defeated in the 10 dB position. There is only one of these for both the AUX A and B sends. It controls the amount of channel input fed equally to the AUX SEND A and B OUTPUTS. This control's range is from off to 0dB, i. e. , there is no additional gain after the input stage. The Aux source is selected from either pre- or post fade via internally located switches. See "4-In 4-Out Modification" to dedicate any input to only one Aux Output. This red LED comes on anytime the input amplifier exceeds a level of 4dB below clipping. These concentric knobs set the signal output level of the MASTER A output (inner knob) and the MASTER B output (outer knob). Indicates power, as indicated. REAR PANEL DESCRIPTION 1. These terminal strip points are used for either microphone or line level inputs. Connect balanced sources to "+", "­" and GND terminals. Unbalanced inputs connect to "+" and GND only. When an unbalanced input is used, the "­" may be left open or shorted to GND. These are unbalanced terminals and noninverting with respect to the inputs. Ground return is picked up from the GND connector located between the output terminals. These "+" and "­" terminals supply a balanced direct output of Master A/B. If balanced operation is your choice, use both terminals. If an unbalanced line is required, use "+" and one of the GNDs located nearby. [. . . ] The module may also be used with the FMM 42 Master Module which features Auxiliary Bus Outputs, which also may be mixed with the A and B Main Outputs for effects mixing. The possibilities are staggering and we shall attempt to describe them, so you may fully understand the range of talent provided by the FPM 44. As an independent 4-input to 4-output mixer, the FPM 44 is a reasonably straightforward device. The 4 Inputs are mixed to either, or both, of two Master buses, A and B, as well as to both Auxiliary buses via the AUX SEND control on the front of the unit. [. . . ]
