RDL RU-ADL2 DSP Dual-Output Audio Delay

The RDL RU-ADL2 is a DSP-based dual-output audio delay for a single analog source, built for the most critical alignment work in a professional audio environment. It takes one mono input and produces two separate mono outputs, each with its own independently adjustable delay from 0 to 135 milliseconds. Time is set in 1 millisecond increments using durable keyboard-style pushbuttons on the front panel, so a technician can time-align delayed loudspeaker zones to a main cluster and lock in the numbers.

All audio connects through XLR connectors or full-sized barrier-block terminals on the rear panel. The input gain is adjustable and metered by a front-panel dual-LED level meter following standard VU ballistics, while the two outputs are fixed at nominal unity gain. The RU-ADL2 runs on ground-referenced 24 Vdc, connected either to the barrier-block terminals or through a rear-panel power jack.
