Rane FPM44 Rackmount program mixer

FRONT PANEL DESCRIPTION


1. INPUT LEVEL CONTROLS. These concentric level controls set the level of each
input to be routed to the Master A/B outputs and buses. The inner knob controls the level to be sent to A, the outer knob controls the signal applied to B. Rotating the knobs together creates a "pan centered" effect. Leaving one off and increasing the other emulates a fall pan to one side.

2. GAIN SELECT SWITCH. 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 l0dB mode is suitable for line level inputs. Phantom power is automatically defeated in the 10dB position.

3. AUX SEND LEVEL CONTROL. 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 A and B Aux 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.

4. OVERLOAD INDICATOR. This red LED comes on anytime the input amplifier ex-
ceeds a level of 4dB below clipping.

5. MASTER A & B LEVEL CONTROLS. 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 + l0dB.

6. POWER INDICATOR. Indicates power, as indicated.
 

REAR PANEL DESCRIPTION

1. CHANNEL INPUT CONNECTORS. These barrier strip points are used for either mi-
crophone 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. Internal Aux pre/post switches determine Aux program.

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.

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, FMM 42 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 input.

7. POWER INPUT CONNECTOR. USE ONLY A MODEL RS 1, FRS 8, 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. Consult the factory for replacement or substitution.

8. CHASSIS GROUND POINT. A 6-32 threaded hole, used for chassis grounding pur-
poses. 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 to 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.

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 pahntom power switches for each channel are internal. For line level applications, phantom power automatically disengages in the GAIN l0dB position.
