AVM-T-MIX
User Handbook Version Three
2.9.3
Physical Sources
Touchmix has a total of 64 available physical sources available taken from SDI, AES and Analog
connections, of which 48 are available at any given time. Each pair can be selected as a stereo or
left only, right only input and routed to any physical output using the routing procedure described
later in this document.
2.9.4
Choosing the active SDI input
In previous versions of the Touchmix SD operating system the user could only access one of the
physical SDI connectors and hence only a single video source could be wired to the box. In the
latest release (from June 2014 onwards) the user is given access to an onboard 2x1 SDI switch
and can choose to de-embed either of the physical SDI ports.
An additional menu has been added to the product to enable this exclusive selection and can be
accessed via the following commands
Setup>SDI> SDI 1A or SDI 1B
The selected SDI input chooses between physical BNC inputs labelled SDI 1 and SDI 2 however to
avoid confusion with the AVM-T-MIX 2SD product, the menu refers to the inputs as SDI 1A and 1B.
Which input is chosen will be routed to the de-embedder and therefore available to the routing
system exclusively for any given User Preset.
2.9.5
Physical Outputs
As previously described in an earlier section regarding the default routing setup, the Touchmix
comprises a total of 26 physical output ports. 16 AES channels (8 pairs) are presented on two D25
connectors, 8 analog channels are presented on a further D25 connector and an additional analog
pair appears on two XLRs.
