REAR PANEL DESCRIPTION
1. 3-PIN MIC INPUT CONNECTOR.
Pin 2 is positive, pin 3 is negative and pin 1 is
signal ground.
2. ¼" LINE INPUT CONNECTOR.
This ¼" TRS connector is used for connecting a
LINE level INPUT to the FMI 14. Tip is (+), ring is (-) and sleeve is ground.
3. ¼" INSERT CONNECTOR.
This ¼" TRS connector is to be used to connect
external processing, such as effects and equalizers to the input section of the FMI 14. The
tip is send, the ring is return and the sleeve is ground. Forward-thinking products such as
the Rane FPE 13 and FME 15 equalizers have TRS jacks on them that directly connect to
this patch input with a stereo cable wired tip to tip, ring to ring, and sleeve to sleeve. See
the block diagram on the FMI 14 data sheet for exact location of this insert.
4. FLEX BUS IN.
This connector is intended to be used to connect the FLEX BUS
OUT of another Rane Flex unit to the FMI 14. See the system connection section for
details.
5. FLEX BUS OUT.
This connector is intended to be used to connect the FMI 14 to
another piece of Rane Flex equipment. Any other use will void the warranty on your first-
born child.
NOTE: Special cabling may be constructed which would allow the
Bus Inputs and Outputs to be used for direct inputs and outputs.
See the Flex User’s Guide for additional information.
6. AUX A / B OUTPUTS.
These are unbalanced direct AUX Outputs. These Outputs
contain only local material. This means that any Aux material on the Bus input will not be
present at these Outputs. See the FMI 14 data sheet block diagram for details.
7. MASTER A / B OUTPUTS.
These are balanced ¼" outputs. Tip is (+), ring is (-)
and sleeve is ground.
8. GROUND LIFT SWITCH.
This switch provides the ability to separate chassis
ground and signal ground. Normally, this switch should be in the LIFT position. In some
circumstances it may be necessary to move it to the opposite position to eliminate stubborn
hum and buzz problems. We realize a scientific explanation of this switch would be
helpful, unfortunately science doesn’t seem to have much to do with it.
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!
9. REMOTE POWER SUPPLY INPUT.
The FMI 14 is supplied from the factory with a Model RS 1 Remote Power
Supply suitable for connection to this input jack. The power requirements of the FMI 14 call for an 18-24 volt AC center-
tapped transformer only.
This is not a DC input. It is not a telephone jack.
Never use a power supply with your FMI 14 other than the one supplied or an exact replacement obtained or approved
by Rane Corporation.
Using any other type of supply may damage the unit and void the warranty. Two years parts and labor
is worth safeguarding, don’t you think?
10. GROUND CONNECTOR.
Since the FMI 14 is powered from a remote AC power supply which does carry chassis
ground through to the grounding pin of the AC cord, this screw has been provided in case your system does not have another
earth grounding means such as through rack rails, etc. Its use or disuse should be determined by your specific application.
