Rane FMI 14 Operating And Service Manual

QUICK START

No one likes to read manuals. Most like to plug in and turn on. That's usually OK, and with
only a very few exceptions, damage is unlikely to result from such procedures with the FMI 14.
First, determine if the input is to be microphone or line and set the MIC/LINE select switch
accordingly. If a microphone is to be used which requires phantom power, set the PHANTOM
POWER switch to its ON position. With the SENDS and MASTER levels all the way down, set
the PAD and GAIN controls so that the highest input will not illuminate the overload light. If
the SENDS are to be used, set the Aux Send selector switches to the desired position. Adjust
the A and B MASTER output levels to deliver the required amount of signal to the bus and
direct outputs.
NEVER CONNECT ANYTHING EXCEPT AN APPROVED RANE POWER SUPPLY
TO THE THING THAT LOOKS LIKE A TELEPHONE JACK ON THE REAR OF THE
FMI 14. This is an AC input and requires special attention if you do not have an operational
power supply EXACTLY like the one that was originally packed with your unit. See the full
explanation of the power supply requirements elsewhere in this manual.

SYSTEM CONNECTION

When connecting the FMI 14 to other components in
your system for the first time, leave the power supply for
last. This will give you a chance to make mistakes and
correct them before any damage is done to your fragile
speakers, ears and nerves.
INPUTS on the FMI 14 are balanced. This means that
standard 3-pin (XLR) connectors on the ends of any good
quality cable will work well with the FMI 14 and micro-
phones of your choosing. As with all Rane products, pin 2 is
used for "hot" or "+" signal polarity, pin 3 is "return" or "-"
and pin 1 is signal ground. If you are using the ¼" TRS line
input, tip is hot, ring is return and sleeve is ground. For
unbalanced inputs, drive pin 2 or tip as hot and pin 1 or
sleeve as ground. It is not necessary to short pin 3 or ring to
ground on Flex series microphone inputs. It will not hurt
anything, either. You may use either pin 1 or case for shield
ground on the 3-pin input. (See Rane Note 110 for further
information on this subject).
OUTPUTS. The FMI 14's Master outputs are balanced.
The Aux outputs are unbalanced. On the balanced outputs,
tip is hot, ring is return and sleeve is ground. If unbalanced
output is required, use only a tip-ring-sleeve connector and
leave the ring unterminated. A "mono" type ¼" (tip and
sleeve only) connector may be used on the Aux outputs.
They are unbalanced only and require no special attention.
Again, have a look at Rane Note 110 for more detail.
BUS OUTPUTS. The 7-pin DIN Bus input and output
may be used only with other Flex modules. These are not
OPERATING / SERVICE MANUAL
MIDI inputs and outputs. A
detailed explanation of the wiring
in these connectors is not neces-
sary. The only thing the user must
know is that only a DIN cable as
supplied with each module from
the factory should be used. If, for
some reason, there is not a cable in
the box with your FMI 14, you
should contact Rane for a replace-
ment. If you are in a bind and need
to make one, a 5-pin DIN may be
used instead of a 7-pin. The two
outside pins are not used on the
FMI 14 and have been included
due to possible future compatibility
requirements. All pins should be
wired "straight through" (1 to 1, 2
to 2, etc.).
A typical FLEX system using FMI 14s would be one
where several FMI 14s are used as input channels for a
mixer with one FMM 42 Master module as the termination.
In a case like this, the first FMI 14's BUS OUT would go to
the second's BUS IN, its BUS OUT to the third's BUS IN,
and so on down the line. The last FMI 14's BUS OUT would
connect to the FMM 42's BUS IN. This would sum all FMI
14s properly. See the Flex User's Guide for additional
details.
