How does the Automation Control Interface work on the 6000 Broadcast Audio Delay and 6100 Broadcast Audio Delay?
The 6000 and 6100 have four internal relays that may be independently used to control station automation events. The relay closures (outputs) are triggered by input closures that can be either manual (a momentary switch closure) or electrical (TTL logic low). When an input closure takes place the audio entering the delay at that moment is ‘tagged’. When the tagged audio reaches the output of the delay its corresponding relay closes for a time equal to the length of the input closure.
