Klark Teknik DN7204 Delay

These units show signs of heavy wear but are in good working condition.

Designed to meet and exceed the needs of the recording, broadcast, installation and live sound industries, the Klark Teknik DN7204 Programmable Delay Line is a high quality, 2-input, 4-output configurable audio delay line that combines state-of-the-art DSP performance with ease of use. With flexible input-to-output routing, each output can be fed from either input, making it easy to build practical configurations such as stereo delay distribution, dual mono zones, or a single input feeding multiple timed outputs for speaker alignment and multi-room installs.

Flexible Routing for System Alignment

The DN7204 supports multiple routing layouts, including Stereo 1-in, 2-out; two independent 1-in, 2-outs; 1-in, 3 out + 1-in 1-out: 1-in, 4-out. This configurability is well suited for time-aligning front fills, delays, and zones in installed systems, as well as managing timing relationships in broadcast and live sound rigs.

Per-Output EQ for Clean, Controlled Results

To further extend the flexibility of the Delay line, the unit also incorporates two bands of parametric equalization and a variable high frequency shelf on each output, allowing you to fine-tune each destination independently. This is useful when different speaker types, placement, or room acoustics require output-specific tonal correction.
