SMX System MultiMatrix Switchers
Also refer to the SMX System MultiMatrix Switchers User's Manual at www.extron.com.
There is only one audio level setting per input and one per
output on an audio plane. The audio level and volume is
shared by the left and right inputs and outputs.
Audio levels and volumes are stored in nonvolatile memory.
When power is removed or restored, settings are retained.
If the audio is set to "follow all", at initial selection (step 2)
the I/O plane and tied I/O buttons light amber. When an
input or output button is held (step 3), the plane blinks red.
Refer to the SMX Users Manual for adjustment methods
using SIS commands.
Front panel adjustment and viewing are only available
when the unit is in Lock mode 0.
