Selecting Mix-Points; Signal Routing - Extron electronics DMP 128 User Manual

Selecting Mix-Points

A mix-point contains a level control and a routing control that mutes or unmutes the signal
path from the input mix-point to the output. Each mix-point in figure 100 on the previous
page has an individual address to identify it for SIS commands (see
table 4 on page 178, and
For example, to view the current status of the input 1 to output 1 mix-point the SIS
command is:
To view the current status of SIS address: 20000) enter:
E
M20000*AU
The response from the DMP 128 is:
DsM20000*1AU
E
M20000*0AU
The command to view the current level setting of a mix-point is:
E X6)
G AU
Looking at the same input 1 to output 1 mix-point (20000), enter:
E
G20000AU
The response is:
DsG20000*1948

-10 dB.

Signal Routing

Mix-point routing is achieved by unmuting the mix-point. To select a mix-point, use the
tables starting on page 176 to find a specific mix-point. In the following example, input 1 is
routed to output 1.
Connecting a mix-point input to an output requires the mix-point be unmuted. Using the
command from the previous examples where X6) is the mix-point, to unmute any processor
or mix-point:
E X6)
M *0AU
The input 1 to output 1 mix-point address, according to
making the correct formula
To break the signal, use the mute formula:
E X6)
M *1AU
In this manner any mix-point can be selected and a connection can be made or broken
between an input and output.
