AMX TDS (Television Delivery System)
For small installations, where possibly only one or two satellite feeds are necessary and a multiswitch has
already been installed it is possible to generate and inject the required DC voltage and tone as shown in
FIG. 99 below.
If ‘high’ band frequencies are not required, the 22khz tone inserter can be removed, however a 13V or 18V DC
voltage are always required to switch the multiswitch outputs.
