DN716 — Multiple Output Digital Delay Line

The DN716 is a 1U rackmount digital delay line with one electronically balanced input and three independently adjustable unbalanced outputs. Each output offers over 1.31 seconds of delay in 20 microsecond steps, making it well suited to multi-zone delay-tower alignment in large-venue PA work where each cluster requires its own time offset from the main system.

Delay Architecture

The single input feeds three discrete delay paths, each adjustable from zero to 1.311 seconds with 20 microsecond resolution. The architecture is built around a high-speed CPU that gives the unit lower component count and improved reliability over earlier discrete designs in the series.

Signal Path

Input and output filters are proprietary low-pass hybrid types, designed for optimum noise performance, low distortion and high reliability. The input is electronically balanced; the outputs are unbalanced, suitable for short runs to dedicated power amplifiers in delay-tower zones.

Application

Multi-zone PA delay alignment, festival main- and side-fill timing, theatre installation work where multiple speaker zones must lock to a single source. The 1.3 second per-output range covers all practical distances in commercial installations.
