1. CHANNEL INPUT CONNECTORS. 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.
2. AUX SEND OUTPUTS. These are unbalanced terminals and non-
inverting with respect to the inputs. Ground return is picked up from the
GND connector located between the output terminals.
3. MASTER OUTPUTS. 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.
4. AUX PRE/POST ASSIGN SWITCHES. Slide switches located inside
the FPM 44. Used to select Aux source to be Pre- or Post- input LEVEL
A/B controls. See the Assembly Diagram. NOTE: AUX ASSIGN
SWITCHES SHIPPED IN "PRE" POSITION.
5. FLEX BUS IN CONNECTOR. This input accepts bus information
from other FLEX mixer modules, such as an FMI 14, FLM 82 or another
FPM 44. This input adds to the program material connected to the FPM
44. The combined results appear at the FLEX BUS OUT jack, as well as
the terminal strip outputs.
6. FLEX BUS OUT CONNECTOR. This seven-pin DIN connector
provides output to other mixer modules, such as another FPM 44, an
FMI 14 or an FMM 42. Signals present here include the AUX of both
this FPM 44 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 IN.
7. POWER INPUT CONNECTOR. Use only a model RS 1, FRS 8, RAP
10, VC 18 or other remote AC power supply approved by Rane. The
FPM 44 is supplied with a remote power supply suitable for connection
to this input jack.
8. CHASSIS GROUND POINT. A #6-32 ground screw is used for chassis grounding purposes. See the CHASSIS
GROUNDING note on the last page for details.
9. GROUND LIFT SWITCH. On this unit, the GROUND LIFT switch is located along the bottom edge (vertical mounting),
or along the right-hand side (horizontal mounting). Since the switch's location prevents easy use once installed, it is
suggested you decide which position is required, and set it before installation. The LIFT position is when the switch is slid
toward the rear of the unit.This switch provides the ability to separate chassis ground and signal ground. Normally, this
switch should be in the lift (rearmost) position. In some circumstances it may be necessary to move it to the opposite
position to eliminate stubborn hum and buzz problems. If you are tempted to try moving this switch with your power
amplifiers turned on or turned up, don't be. Always turn your amplifier levels down before changing your grounds around
and then bring them up slowly. Put a speaker re-coner out of work today!
10. MASTER PHANTOM POWER SWITCH & LIGHT. On this unit, the MASTER PHANTOM POWER switch is located
along the top edge (vertical mounting), or along the left-hand side (horizontal mounting). Since the switch's location
prevents easy use once installed, it is suggested you decide if Phantom Power is required, and set it before installation. The
ON position lights the LED when the switch is positioned to the rear of the unit. Individual internal PHANTOM POWER
switches allow Phantom to be defeated on selected channels. See the Assembly Diagram. For line-level applications,
phantom power automatically dis-engages in the GAIN = 10dB position.
