The syntax for setting a special function is __ * X? # where __ is the function number and X? is the value.
To view a function’s setting, use __#, where __ is the function number. In the following table the values of
the
X? variable are different for each command/function. These values are given in the rightmost column.

(host to switcher) (switcher to host) and additional descriptions
Delay times
Set the RGB delay (Triple-Action Switching). 3 * X? # RGBDly* X? 0 = 0.0 seconds (default), 1 = 0.5
seconds, 2 = 1.0 seconds,
... in ½ second steps up to
10 = 5.0 seconds
Example: 3*7# RGBDly*07 Example: 3.5 second RGB delay.
Audio settings
Set the preamp output mode. 18 * X? # PreAmpMod* X? Set the Audio Out (fixed and
variable) connectors’ output to
be either mono or stereo signals.
1 = mono
2 = stereo (default)
Enable/disable the Effects Return. 19 * X? # EffectIn* X? This setting of for the
MLS 506MA and MLS 506SA
only.
0 = disabled (default)
1 = enabled
Set the left-right audio balance. 22 * X? # Balance* X? Set the attenuation applied to
the left and right audio
channels.
0 = attenuate the left audio
channel 100% (mute the left,
scroll bar is at the right)
...
20 = 0dB attenuation for both
channels
...
40 = attenuate the right channel
100% (mute the right, scroll bar
is at the left)
Select the stereo output speaker load 23 * X? # SpkrLoad* X? Tell the MLS 506SA the total
impedance of speakers that are
attached to the stereo amplified
output.
1 = 4 ohm total load (default)
2 = 8 ohm total load
• If the Effects setting is disabled, the
Effects Send connector still outputs an
audio signal, but the Effects Return
connector will be internally disabled so
any audio signal present there will not
reach the Audio Out or amplified output
connectors.
• If the Effects setting is enabled, any
audio signal input via the Effects Return
connector will be output via the Audio
Out connector and the amplified output
(if applicable).
If mono is selected, the audio signal will
be the same on both the left and right
channels. If stereo is selected, the
switcher will send out different (stereo)
signals on the left and right channels.
