SM 26B CONNECTION

When connecting the SM 26B 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

before damage is done to anything fragile.

As you have no doubt noticed, all Inputs and Outputs on

the SM 26B’s rear panel are ¼" connectors. The Inputs and

Outputs are active balanced on Tip-Ring-Sleeve (TRS) jacks

which allow the flexibility of connecting in either a balanced

or unbalanced fashion. If unbalanced operation is your

preference, the simplest way to accomplish this is through the

use of tip and sleeve ¼" connectors. The ring is not essential

unless balanced operation is required. You should be aware

that if you are running unbalanced and using TRS connectors

with both ring and tip, the ring and sleeve must be shorted

together. Failure to do so on the inputs results in a gain loss of

6 dB.

Balanced operation requires that TRS plugs be used. The

tip is hot (+), the ring is return (–) and the sleeve is ground.

RaneNote 110, “Sound System Interconnection” (included

here) contains some great pictures to aid your interconnect

ventures.

QUICK START

Realizing that in most areas there are laws against reading owners manuals, and that reading them under the blankets at

night with a flashlight makes you feel stupid, we therefore provide this brief, yet informative, description of how to use the

SM 26B just in case your batteries are low and your mother is about to come in the room.

To achieve a quick understanding of the SM 26B, think of it as a six channel mixer with faders and pans only. Or think

of it as a 2-to-6 channel splitter with output level controls and a mix knob (to control how much of which input goes to

which output). If you get that, you may stop here as long as you know how to hook up the power supply.

As a six channel mixer, MONO IN 1 through 6 may be placed on the Right or Left bus or both, in any amount. The

respective LEVEL knobs on the front of the unit serve as the mixer’s faders, the adjacent PAN controls place the channel’s

signal into the stereo field. As an effects mixer or line level expander for a larger mixer, set up the LEVELS and adjust the

PANS. The MASTER OUTPUT LEVEL adjusts the overall level of the mix at the Master Outputs.

As a splitter, place one or both input signals into the LEFT and/or RIGHT Inputs. Select the Input(s) to be placed at

each of the six MONO OUTs by rotating the MIX/PAN control to the proper position. Set the individual CHANNEL

LEVEL controls for proper output level. The MASTER INPUT LEVEL control on the front adjusts both Right and Left

Input signal levels together.

Never connect anthing except an RS 1 or other approved Rane AC power supply to the red thing that looks like a

telephone jack on the rear of the SM 26B. This is an AC input and requires some 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.
