Field Report: 25-Seven Systems PLM
The PLM can be used on the fly in a broadcast to squeeze in a news brief or a promo. To do this, route the live show through the PLM. When the news brief or promo needs to be inserted, press the buffer button. Now input audio is held (recorded) in the PLM buffer, and the inserted audio can be aired. Once the inserted audio is finished, press play and the show resumes from where it left off. The remainder of the show will now be shrunk to fit the allotted show time. You can adjust the rate at which the show will be shrunk with the up and down arrows.
The PLM will enable our show producers to not have to worry as much about hitting an exact time on their pre-recorded shows and focus more on the content of the show. In its short time here at Radio Free Asia we have had the opportunity to use it on air for two different language services shows. In one case, we were asked to insert a three-minute music piece into a program that was already 60 minutes, its allotted time. We were able to shrink the program in real-time so that the 63-minute source program was able to fit in the allotted time slot. In the other case, a 60-minute program was almost 3 minutes short. We expanded it in real-time to a full 60 minutes as it was being broadcast.
