The Klark Teknik model DN7103, a single input, three output user configurable digital delay line with 1.4 seconds of total delay time, offers a host of features whilst maintaining the ease of operation for which Klark Teknik products are renowned. The primary purpose of the DN7103 is for synchronisation of sound paths in multiple signal distribution systems and multiway loudspeaker systems in theater and public address installations and touring sound reinforcement systems, although it will also prove useful in delaying audio for video in post productionf suites and synchronisation of audio for satellite transmissions.
