RU-ADL2

RDL RU-ADL2 - Professional Audio Delay Processor - 0 to 135 ms

The RDL RU-ADL2 is a high-performance DSP-based audio delay processor designed for professional AV, broadcast, and sound reinforcement applications. It accepts a single mono audio input and provides two independently adjustable mono outputs, each with a delay range from 0 to 135 milliseconds in 1 ms increments.

The unit features a bright 3-digit LED display for precise delay readout and keyboard-style pushbuttons for intuitive adjustment. Each output can be configured separately, and delay settings are stored in non-volatile memory to ensure retention after power loss. A locking pushbutton allows bypassing the delay section without losing stored values.

The RU-ADL2 supports full remote control, including a lockout function to disable front-panel adjustments. Audio connections are available via XLR and barrier block terminals. A dual-LED level meter with VU ballistics provides real-time input monitoring. The unit operates on 24 VDC and can be used standalone or in parallel with other RU-ADL2 modules for multi-output delay systems.
