The RU-AVX4 is the ideal choice in installations where a single set of audio/video signals needs to be selected from up to 4 consumer format (phono jack) video and audio sources. Video signal quality, audio performance and pushbutton durability are equal to that found in professional switchers. Audio and video source selection uses all solid-state switching. High quality audio and video line driver amplifiers feed the module's output.

The RU-AVX4 has four separate inputs and a single output on the rear panel. The inputs and output provide one video phono jack and two associated (left and right) audio phono jacks. When power is first applied to the module, input 1 (default) is automatically selected. Four keyboard style long-life pushbuttons on the front panel are used to select one of the inputs at a time. When a button is pushed, the corresponding video and audio input is fed to the output of the RU-AVX4 and any previously selected source is shut off. Only one source may be selected at a time.

The RU-AVX4 rear-panel terminal block provides four connections to remotely control the module. A momentary external closure to ground on an input terminal will select the associated input. Continuous remote closures will select inputs while disabling source selection by the front-panel buttons. An LED indicator above each front-panel button shows which input is selected.

RACK-UP SERIES

RACK-UPs are the original 1/3 rack width 1RU rack-mountable modules for the A/V, recording and broadcast industries. Module functions include mixing, switching, pre-amplification, power amplification, distribution, gain control, equalization and more. Some RACK-UP modules are constructed in solid encapsulated durable industrial black plastic enclosures; MAX RACK-UPs are assembled using heavy duty extruded aluminum and steel panels. The rear panels feature clear bold white lettering for the terminal blocks and connectors. Reverse-printed front-panel polycarbonate laminates provide an attractive, durable finished appearance for rack-mounted or free-standing use.

Since RDL first originated 1/3 rack width modules, RACK-UPs have led the industry in economical, high-performance and cost-effective long life solutions in system designs. Multiple RACK-UP modules may be interconnected, or may be connected with other RDL modules to form all or part of an A/V system. Certain RACK-UP modules are often used free standing; all RACK-UPs may be rack mounted. A complete range of mounting options is available for systems comprised of multiple modules.

RACK-UP modules provide input, output and control connections through terminal blocks and connector (or both) according to common usage in professional installations. Front panels are equipped with connectors, user controls and LED metering, as appropriate.

Functions and features provided by RACK-UPs, since their introduction, are still available today. This continuity in product offering and support makes RACK-UP modules a preferred long-term resource for system design solutions. RACK-UP SERIES modules are designed and manufactured in the U.S.A.
