OPERATORS MANUAL SM82S
STEREO MIXER
QUICK START
No one likes to read manuals. Everyone likes to just start pushing buttons and turning knobs until the desired results magically
emerge. at’s usually OK, and with a very few exceptions, damage is unlikely to result from such procedures with the SM82S.
is product is quite obvious: Input LEVEL controls make Inputs louder or not, the stereo SENDs make things happen at the
LOOP SEND outputs, and so on. No real magic there. You should be aware, however, that if you want to connect a mono source to
the SM82S, use only the LEFT Input of a channel so that the mono source will drive both the Left and the Right channels.
Set the levels of the mixer so that the red lights stay o. If they come on, you are overdoing it and distortion will result.
SM82S CONNECTION
When connecting the SM82S to other components in your
system for the rst time, leave the power supply for last. is will
give you a chance to make mistakes and correct them before any
damage is done to your fragile speakers and ears.
If you are making your own cables, or experience any hum
problems after hookup, please refer to the RaneNote, “Sound
System Interconnection” (supplied with this manual and avail-
able at rane.com).
INPUTS
e SM82S’s Inputs are unbalanced. is means that standard
¼" connectors on the ends of any good quality cable will work
well between your signal sources, signal processing and ampli-
cation. For best rejection of nasty things like hum and RF,
keep input cables under 10 feet (3 meters) in length.
Most sources give you the choice of stereo or mono output.
e mixer gives you the same choice. You will note that nomen-
clature has been placed beneath the input jacks indicating which
is RIGHT and which is LEFT (MONO). If a source is plugged
only into the Left jack and not into the Right, both Right and
Left channels will be fed with the Left Input. is allows the use
of either stereo or mono sources.
OUTPUTS
e SM82S oers balanced main outputs only. is means that
you may use them as either balanced or unbalanced, the choice
being made by the way the connectors are wired. It’s a good idea
to always use a TRS or stereo connector in the outputs no matter
which mode you are using. If a “mono” connector is used, insert-
ing it into the output will short the ring (–) to ground and could
conceivably cause a small amount of distortion to be placed on
the tip (+). While this is not destructive, it may be signicant
enough to be audible. Balancing therefore requires that both tip
(+) and ring (–) be wired to the following device. Unbalanced
requires only tip and sleeve connected, leaving the unused ring
open.
EFFECTS DEVICES
External devices which might be used could be either mono in
and out, while some may be mono in and stereo out, while still
others may be stereo on both ends. e SM82S easily accom-
modates all of these varieties. If your eect is mono on both
ends, connect its input to the SM82S LEFT LOOP SEND and
the eect’s output to the SM82S LEFT LOOP RETURN. is
conguration will sum Right and Left Loop Outputs to the
mono eect input and will sum the mono eect output to the
Left and Right Input buses. A mono-in stereo-out device would
connect to the loop outputs in the same way; however the stereo
outputs connect to the respective LEFT and RIGHT LOOP
RETURNS.
EXPANDING
Connecting two or more SM82Ss together to achieve more than
eight stereo Inputs requires that a stereo cable (tip, ring, sleeve)
be connected between the MAIN EXPAND OUTPUT of the
rst mixer and the MAIN EXPAND INPUT of the second.
All 32 inputs will then appear at the main OUTPUT of mixer
number two. Only the rst sixteen Inputs will be available at the
main Outputs of mixer number one. Should you wish to have all
Loop buses tied, connect the LOOP SENDS of mixer one to the
LOOP EXPAND INPUT of mixer two. All sixteen stereo sends
will then become active at the LOOP SENDS of the second mix-
er. e expand Inputs and Outputs are unbalanced signals, so to
prevent hum, keep expand cables under 10 feet (3 meters) in
length.

FRONT PANEL DESCRIPTION
1Input LEVEL controls: are rotary stereo attenuators that adjust the amount of both Left and Right signals applied to an Input.
Outputs are summed for mixing with all other Inputs. e unity gain position of this control is located at “7.5.”
2Input OverLoad indicators: glow red whenever its corresponding Input’s output exceeds a level 4 dB below clipping, letting you
know it’s a good idea to turn this Input down a bit.
3Input PAN controls: operate as ‘PAN’ with a mono signal, and ‘BALANCE’ with a stereo signal.
PAN: When a mono input is used (no plug in the RIGHT Input jack), the signal ‘moves’ from the Left to Right channels. At the
“L” extreme top of travel the sound source is heard from the Left output; at the other “R” extreme bottom it is heard only from the
Right output. In the middle, the sound is heard equally from each output, but is reduced in level by 3 dB relative to its original
value. is guarantees that as the sound is panned from one side to the other, it maintains equal loudness (power) for all positions.
BALANCE: In its center detent, Left and Right signals to each channel are allowed to pass at their original relative levels, there-
fore preserving the stereo image from devices connected to both of the Inputs. When the control is moved vertically toward the
“L” position, the Right channel level is decreased while the Left channel level is maintained. e opposite occurs if the control is
moved from the detent down toward the “R”.
4Input SEND Level controls: determine the amount of Post-Fade stereo Input is fed to the Loop Send buses. Each Input’s stereo
SEND is summed on this bus and is available at the respective LEFT and RIGHT LOOP SENDS on the rear of the mixer.
5RETURN LEVEL control: is a rotary stereo attenuator that controls the amount of Return which is to be added to the Main
Output. e unity gain position of this control is located at “7.5."
6RETURN OverLoad indicator: glows red whenever the return levels exceed a level of 4 dB below clipping.
7RETURN PAN control: is a vertical slider that controls the eect or source connected to the LOOP RETURN in the same way
the Input PAN controls work (see 3above).
8OUTPUT LEVEL control: is a rotary stereo attenuator that controls the nal signal Level at the main OUTPUT jacks. e
unity gain position of this control is located at “7.5".
9OUTPUT OverLoad indicator: glows red any time the output level exceeds 4 dB below clipping.
qOUTPUT PAN control: is a vertical slider that operates in the same fashion as the PAN control described in item 3above. It
however, determines the relative levels of the LEFT and RIGHT MAIN OUTPUTS only.

REAR PANEL DESCRIPTION
1Channel Input jacks: consist of eight pairs of unbalanced ¼" tip-sleeve jacks, used to connect any line-level signal source to the
SM82S. As indicated, only the LEFT is to be used if the Input is mono and should therefore appear in both Left and Right chan-
nels, depending on the position of the front panel PAN control.
2MAIN EXPAND INPUT: A ¼" TRS stereo Input jack may link two or more SM82Ss together, or accept the output from
another mixer. is may also be used to sum any xed-level stereo signal into the Main Outputs, producing a ninth stereo Input
when added with 1. A stereo Tip-Ring-Sleeve cable must be used here. e Left input is on the Tip, Right is on the Ring and the
Sleeve is ground.
3LOOP EXPAND INPUT: Another ¼" TRS stereo Input, expands the stereo Loop buses of two SM82Ss so they share the same
eects loop. A stereo Tip-Ring-Sleeve cable must be used here. Connect the LEFT and RIGHT LOOP SENDS (4)of the rst
unit to the LOOP EXPAND INPUT of the second SM82S. (Tip = left; Ring = right.)
4LOOP SEND: is pair of ¼" jacks may drive an eect or similar device which is to be returned to item 5below. If a mono
device is used, both the Left and Right Send channels of the SM82S are summed together and presented at the LEFT Output if
nothing is inserted in the RIGHT Output.
5LOOP RETURN: ese ¼" aux returns may connect the output of a reverb or other eect unit to the Loop bus of the SM82S.
If no eect is used, they can be used as a tenth stereo Input to the mixer in addition to those described in 1 and 2. As with the
other stereo Inputs, mono signal may be connected to the LEFT input to obtain two-channel mono operation.
6MAIN EXPAND OUTPUT: is ¼" TRS stereo (Tip = left, Ring = right) Output jack connects one SM82S to another for the
purpose of expanding the number of Inputs available. Use only a stereo plug in this jack — a mono jack or cable will cause loss of
Right channel signal and possibly distortion to the Left channel. is Output also serves as a xed pre-fader level useful as record
outputs or other applications. A send/return cable can be ideal for this output to drive a second amplier or recorder. See the dia-
gram below.
7Main BALANCED OUTPUT: ese balanced Tip-Ring-Sleeve jacks connect the main Outputs of the SM82S to a power am-
plier or to additional signal processing. As is the AES standard with all Rane balanced outputs using ¼" TRS jacks, the Tip is (+),
the Ring is (–) and the Sleeve is ground.
8 Power connector: e internal universal switching power supply operates on any AC mains 100 to 240 VAC, 50 or 60 Hz (most
places in the world). All that is required when traveling is the appropriate IEC line cord.

OPERATING INSTRUCTIONS
CIRCUIT DESCRIPTION
Learning to operate the SM82S might be a bit easier if you
glance at the Block Diagram below. All eight stereo Inputs
operate in exactly the same way. Signal applied to the Inputs is
acted on by a radio interference lter (we have assumed that local
broadcasts should not be a part of your music) and is then routed
to a stereo LEVEL control. If you are using a mono source, con-
nect it only to the LEFT Input to send this mono signal to both
the Left and Right sides of the input circuitry. e output of the
Level control sections is applied to a unity gain buer to prevent
the LEVEL control from adversely interacting with downstream
circuitry. e Input overload sensor monitors here to alert the
user via LED to any possible Input overload conditions. Left and
Right audio is then subjected to the channel PAN control to al-
low the user to place the stereo image of the source as desired to
the Left and Right Outputs. A stereo SEND control adjusts the
amount of each Input routed to the Loop Output.
All eight stereo Inputs are simultaneously adjusted for stereo
placement by the OUTPUT PAN control. e resultant signal is
added together and fed to the OUTPUT LEVEL control, which
has it’s own Overload indicator. e main Outputs are fully
actively balanced, allowing the use of correctly wired long cables.
EFFECTS LOOP
e LOOP SENDS receive their audio from the Send bus which
is the sum of all the Inputs as determined by the Input SEND
controls. is Output may be used to drive a stereo eects pro-
cessor. e output of the eect device is returned to the SM82S
through the LOOP RETURNS. e level of the returned eect
is determined by the RETURN LEVEL control on the front
panel. e return section also provides a BALance control for
image placement.
PAN / BALANCE CONTROLS
ese operate as ‘PAN’ with a mono signal plugged in the LEFT
input only, and ‘BALANCE’ with a stereo signal (both jacks
plugged in). ese do not increase the level of either Left or
Right signal. As the controls are moved toward one channel, the
level of the other channel is only reduced.
HIGH NOISE IMMUNITY
One of the most unusual features of the SM82S is its inher-
ent immunity from noise. All eight of the stereo inputs may be
turned all the way up without increasing the internal noise of
the mixer. is is critical due to the wide variation in output
levels found in musical instruments and tape devices. A fairly
low-level guitar may be combined in the same system with a
high level synthesizer without any undesirable side-eects. e
SM82S eliminates the concerns normally associated with mixing
so-called -l0 dBV units with +4 dBu types.
