REAR PANEL DESCRIPTION

1

 Channel 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.

2

 MAIN EXPAND INPUT: 

A ¼" TRS stereo Input jack may link two or more SM82Ss together, or accept the output from 

another mixer. This may also be used to sum any fixed-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. The Left input is on the Tip, Right is on the Ring and the 

Sleeve is ground.

3

 LOOP EXPAND INPUT: 

Another ¼" TRS stereo Input, expands the stereo Loop buses of two SM82Ss so they share the same 

effects loop. A stereo Tip-Ring-Sleeve cable must be used here. Connect the LEFT and RIGHT LOOP SENDS (

4

)

 of the first 

unit to the LOOP EXPAND INPUT of the second SM82S. (Tip = left; Ring = right.)

4

 LOOP SEND: 

This pair of ¼" jacks may drive an effect or similar device which is to be returned to item 

5

 below. 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.

5

 LOOP RETURN:

 These ¼" aux returns may connect the output of a reverb or other effect unit to the Loop bus of the SM82S. 

If no effect is used, they can be used as a 

tenth 

stereo Input to the mixer in addition to those described in 

and 

2

. As with the 

other stereo Inputs, mono signal may be connected to the LEFT input to obtain two-channel mono operation.

6

 MAIN EXPAND OUTPUT: 

This 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. This Output also serves as a fixed pre-fader level useful as record 

outputs or other applications. A send/return cable can be ideal for this output to drive a second amplifier or recorder. See the dia-

gram below.

7

 Main BALANCED OUTPUT:

 These balanced Tip-Ring-Sleeve jacks connect the main Outputs of the SM82S to a power am-

plifier 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.

Power connector:

 The 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.

ALL INPUTS ARE UNBALANCED
