You Need The RU-AVX4!

The RU-AVX4 is part of the group of versatile RACK-UP products from Radio Design Labs. RACK-UPs feature the
advanced circuitry for which RDL products are known, combined with accessible, user-friendly controls and displays.
The ultra-compact design permits high-density installations, with three products mounted in a single rack unit!
Optional surface mounting brackets and rack-mount adapters (RU-RA3HD) are available.

APPLICATION: 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. The next source selection may be
made from either the front-panel buttons or from a rear-panel terminal. Because the remote control terminals require
a momentary closure to ground, the RU-AVX4 may be controlled from a variety of RDL wall mounted remote
controls. It also may be connected as a slave from other RDL 4-input modules, or from other switching circuits.
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, whether the input was selected from
the front panel or by remote control. The RU-AVX4 operates from 24 VDC which may be connected either through
the DC power jack or the terminal block. An internal automatically resetting fuse protects against damage if the
power terminals are accidentally shorted while power is applied through the DC jack.

Wherever low noise and low distortion audio coupled with professional quality video switching is required for
consumer format signals, the RU-AVX4 is the ideal choice. Use the RU-AVX4 individually, or combine it with other
RDL RACK-UP or STICK-ON
