MLM 82 CONNECTION
When connecting the MLM 82 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 sixteen jacks at the Inputs of the MLM 82 are
balanced. They will also accept unbalanced connectors. Use
only shielded cable for Inputs. For best noise rejection use
two-conductor-plus-shielded wire, even for unbalanced
operation. Connect the shield at both ends to help insure
proper grounding. See the Sound System Interconnection
RaneNote included with this manual for all cable adaptations.
MONO INPUTS 1-4.
Connect up to 4 sources to these
XLR jacks. Rane follows the AES recommended practice of
pin 2 postive, pin 3 negative, and pin 1 to shield. Switch any
Input connected to a microphone to the
mic
position by the
associated “limited access” switches on the front panel (LED
off
). When connecting line level signals, switch the input to
the LINE position (LED
on
). Use a small probe such as a #0
Phillips screwdriver to actuate the switch.
STEREO INPUTS 5-8.
The ¼" connectors are line level
stereo/mono balanced/unbalanced Inputs. If the MLM 82 is to
be used with unbalanced sources (such as CD players),
QUICK START
This section is provided as a convenience for those in a rush. If you are experienced with this unit or other Rane
products, these few words will refresh your memory.
INPUTS 1
through
4
may be microphone or line level. The choice between the two is made by setting the
LINE
push-
buttons through the access holes on the front of the unit near the
INPUT LEVELS
. Follow the silk-screening on the rear
for proper wiring hookup.
Choose between
MIC
or
LINE
output levels at each of the XLR
OUTPUT
connectors. If the MLM 82 is connected
directly to a power amplifier, equalizer or recorder input, choose
LINE
level. If the MLM 82 is connected to a microphone
jack of an existing sound system, choose
MIC
level. Follow the silk-screening on the rear for proper wiring hookup.
Once Inputs, Outputs, and power are properly connected, with the
OUTPUT LEVELS
counterclockwise (
off
), set the
Input
LEVELS
as high as possible without causing the
SIG/OL
indicators to blink red more than occasionally during
extreme signal peaks. Now slowly raise the
OUTPUT LEVELS
as desired.
Never connect anything except an approved Rane power supply to the red thing that looks like a telephone jack on
the rear of the MLM 82.
This is an AC input and requires special attention if you do not have a power supply
exactly
like
the one that was originally packed with your unit. See the full explanation of the power supply requirements on page
Manual-3.
consult the Sound System Interconnection RaneNote included
with this manual for proper wiring using ¼" TRS input
connectors. Stereo Inputs use both RIGHT and LEFT jacks at
each INPUT.
INPUTS 5 through 8 also serve as mono Inputs by either
using the XLR inputs (always mono) or by plugging into only
one of the ¼" jacks. Automatic switching occurs when only
one of these ¼" jacks are used at any Input, splitting the mono
signal to both Outputs. Connect to just one of these jacks and
the MLM 82 does the rest. If you only want the signal to
come out of one channel and not the other, plug an unwired
“dummy” ¼" plug into the other channel.
OUTPUTS
The MLM 82’s OUTPUTS are balanced. The same wiring
conventions as the XLR Inputs apply. The type of device
following the MLM 82 must be considered when setting the
Output Level switch. Choose between LINE (0 dB) or MIC
(-40 dB) output levels. If the MLM 82 is connected directly to
a power amplifier input, choose LINE level. If the MLM 82 is
connected to a microphone jack on an existing sound system,
choose MIC level. For unbalanced OUTPUT connections do
not tie pin 3 (i.e. “–”) to ground.
