Overview

The RU-ADL2 is a DSP based dual-output delay for an analog audio source. It provides exceptional audio performance for the most critical applications in a professional audio environment. The RU-ADL2 accepts a single monaural audio input and provides two separate monaural outputs. The time delay on each output is individually adjustable from 0 to 135 mS. A large, bright 3-digit LED numeric display on the front panel shows the time delay set for each of the two outputs. A locking pushbutton switch selects the output to be displayed and adjusted. Time adjustment is made in 1 mS increments using durable keyboard style pushbuttons on the front panel. If a button is held, the time will first ramp slowly, then more rapidly permitting easy course and fine adjustment of the time delay. A locking pushbutton permits the user to completely bypass and return to the DSP time delay section without losing the stored delay values. Time delay values are stored in a non-volatile memory so the RU-ADL2 returns to the correct settings following any interruption of power.

Rear panel terminals provide full remote control of the RU-ADL2 including a LOCKOUT terminal to disable the operation of the front-panel time adjustment buttons. All audio connections are made through XLR connectors or on full sized barrier block terminals provided on the rear panel. The INPUT GAIN is adjustable and is equipped with a front-panel dual-LED LEVEL meter that follows standard VU ballistics. A green LED illuminates at 15 dB below +4 dBu, becoming progressively brighter with increasing audio level. The adjacent red LED illuminates when the audio level exceeds +4 dBu. The output levels are fixed at nominal unity gain. The RU-ADL2 operates from ground-referenced 24 VDC power, connected either to barrier block terminals or through a power jack on the rear panel. The RU-ADL2 may be used as a standalone delay, or its input may be connected in parallel with multiple RU-ADL2 modules to provide additional delayed outputs.
