OPERATING / SERVICE MANUAL FMM 42
MASTER MODULE
QUICK START
Operating Manuals! You can’t live with them; you can’t live without them. If you don’t
read them, the damn thing never works right; and if you do read them, you get so confused you
never get it turned on! For you, we present the famous Quick Start section. Read this, and you
get dessert.
If you are using the FMM 42 as a master mixing module, connect the FLEX BUS OUT of
the last mixing module to the FLEX BUS IN on the FMM 42 using the 7-pin DIN patch cable
supplied. Aux bus program is routed through the AUX BUS level controls and then the AUX
BUS LOOP jacks and into the MASTER A/B outputs. Insert your reverb, or any other signal
processing unit, into the BUS LOOPS, by means of the tip=send, ring=return jacks. In addition
to the BUS input, the FMM 42 has a MIC/LINE 1 input and a STEREO LINE 2 input. The
MIC/LINE 1 input is equipped with a Ducking (attenuating) feature, allowing its use as a
priority paging input. This allows voice or other signals to override or attenuate (duck) all other
program routed through the FMM 42. The BUS THRU jack allows routing of the unaltered
Flex bus material to another FMM 42 or other Flex bus equipped module. The FMM 42 may
also be used stand-alone, without any bus inputs, as a straightforward background music/paging
system or the like. In this case the AUX BUS LOOP jacks may be used as additional line inputs
by using special ¼" TRS cables with tip left open, ring as signal hot and sleeve as ground.
NEVER CONNECT ANYTHING EXCEPT AN APPROVED RANE POWER SUPPLY
TO THE RED THING THAT LOOKS LIKE A TELEPHONE JACK ON THE REAR OF
THE FMM 42. 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 FMM 42 to other components in
your system for the first time, LEAVE THE POWER
SUPPLY FOR LAST. This gives you a chance to make
mistakes and correct them without damage to your fragile
speakers, ears and nerves.
INPUTS. The MIC-LINE 1 INPUT on the FMM 42 is
balanced. This means that standard 3-pin (XLR) connectors
on the ends of any good quality cable work well with the
FMM 42 and a microphone of your choice. In compliance
with American, British and International standards, pin 2 is
used for “hot” or “+” signal polarity, pin 3 is “return” or “–”
and pin 1 is signal ground. For unbalanced inputs, drive pin
2 as hot and pin 1 as ground. It is not necessary to short pin
3 to ground on Flex series microphone inputs; however, it
will not hurt anything, if you do. 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). If you are using
the ¼" STEREO LINE 2 input, tip is Channel A, ring is
Channel B and sleeve is ground.
OUTPUTS. The FMM 42’s Master Outputs are bal-
anced. On these outputs, pin 2 is hot (+), pin 3 is return (-)
and pin 1 is signal ground. If unbalanced output is required,
use pin 2 as hot and pin 1 as ground. Do not short any pins to
any others. This is not a transformer balanced output.
BUS INPUTS. The 7-pin DIN
bus connectors are used primarily
with other Flex modules. These are
not MIDI connectors. Use only the
supplied DIN cable. If for some
reason there is not a cable in the
FMM 42 box, please contact Rane
for a replacement. If you are in a
bind, a 5-pin DIN may be used
instead of a 7-pin. The two outside
pins are spares on the FMM 42 and have been included for
possible future compatibility reasons. All pins on the DIN
cable should be wired straight through, i.e., 1 to 1, 2 to 2,
etc.
A typical Flex system using FMM 42s would be where
several FMI 14s are used as input channels, possibly mixed
with a FPM 44 program mixer, all combined with one FMM
42 as the master termination module. In a case like this, the
first FMI 14’s BUS OUT goes to the second’s BUS IN, its
BUS OUT to the third’s BUS IN, and so on down the line.
FPM 44s, FPM 42s, and FLM 82s connect the same way.
The last BUS OUT connects to the FMM 42’s BUS IN. This
sums all input modules properly. See the Flex Users Guide
for additional details.
