Configuration Wizards
Auto-setup button
The Auto-Setup function will help you configure your system and then run the Auto-EQ and Auto-Feedback
wizards.
MODE parameter
The SETUP Wizard starts with configuring the Inputs and outputs. You can choose mono or stereo input
operation and the number of outputs used. i.e. 2x3 means stereo input with a three way crossover using all 6
outputs. Setting the mode to 1x4 configures the unit as a mono input ("A") with 4 outputs. After this step, click
on the Next parameter to advance to the next menu item.
Out 1...Out 6 parameters
The next step is to choose the stored speaker data to use for each output. Stereo operation will group the
outputs into even and odd pairs (1&2, 3&4 etc).
Note: If you choose 2x2+1 mode, the Auto-setup wizard assumes that OUT5 will be used for the mono
subwoofer output 1 .
Note: When using a sub-woofer you will have to adjust the High Pass filter frequency and slope of the low
frequency speaker to match the upper cutoff frequency of the sub-woofer.
As each speaker is assigned, it is followed up by assigning a Power Amp to the same output. After the power
amps are assigned, you can re-name each output using up to 6 characters. Once you have completed the first
output the process repeats for the next output until all are completed.
The unit is not actually configured until you hit Next when prompted. Since this takes some time to complete,
a "Loading Please Wait" message appears in the LCD display while the unit works to retrieve the info.
When the SMS226 is fully configured, you have the option of running the Auto-EQ wizard by clicking on the
Next parameter, or Exiting.
Auto-EQ button
The Auto-EQ function of the SMS226 requires an APEX 220 instrumentation mic plugged into the
front panel XLR jack.
The unit generates pink noise and sends this to all of the outputs. The external mic allows the unit to
measure the response of the system and to make corrections using the internal 1/3 octave EQ. This process is
automatically repeated a number of times to obtain the best results.
Push Auto-EQ to start. Note that every sub-menu now offers the Exit function. Exit will return you to the
Configuration screen with no changes to the EQ.
Push the encoder knob to adjust the Set EQ flat or rotate to Setup, Run, or Exit. Push the encoder knob to
proceed.
Setup will allow adjustment of how the Auto-EQ operates. Most of the parameters have suitable defaults and
you should not have to modify them. You should at least review the low band limit and set it to the low
frequency cutoff of your system.
You can set the number of times to repeat the process (Default = 10), the Precision, the Target curve (adjust
each of the 31bands + 4dB), the extreme bands to limit the process
2
, and the Mode (the averaging can be set
to either absolute or mean).

If this is a problem, you can manually configure the unit using the output function switch.
