The Teach Logic ALS-960 digital time delay module can be added to a receiver to synchronize distant audio speakers with the program audio location. The digital time delay module can be installed with the receiver to delay the output signal of the receiver from 20–500 milliseconds.The LCD displays the delay time in milliseconds.

The ALS-960 transmitter also functions as a very handy 2 channel mixer by combining the aux line level input and the ¼" mic input. This allows both pre-recorded program material and a live microphone to be broadcast at an event with no additional mixing equipment required.
