The RU-TPS4A is a four output audio sender, signal and power distributor module compatible with RDL Format-A twisted pair products. Three line-level sources may be connected to the module using the +4 dBu balanced detachable terminal block. A bank of studio-quality buffer amplifiers feed the three pairs of the four rear-panel RJ45 OUTPUT jacks at the correct operating level.

Three RDL Dual-LED VU meters are provided on the front panel of the RU-TPS4A. One meter monitors the audio level on each of the three FORMAT-A audio pairs. A GAIN trimmer adjacent to each meter allows front-panel adjustment of each audio input for optimum operating level.

The RU-TPS4A is constructed in the durable MAX RACK-UP chassis which facilitates mounting three distributors in a single rack unit. Installations requiring more than four distributed outputs are easily accommodated by mounting one or more RU-TPDA Distributors adjacent to the RU-TPS4A. A wide variety of mounting accessories are available in the RDL RACK-UP series. A power bus in each RU-TPS4A allows power to enter one module at either side of the rack. The included power jumper cable provides a simple method of interconnecting the RU-TPS4A to an adjacent distributor module, so multiple modules can be operated from a single power supply.

The RU-TPS4A is powered directly from a 24 Vdc power supply using either one of the power jacks or the detachable terminal block. Local power connected to the module is also fed to all modules connected to the OUTPUT RJ45 jacks. The power feeding each OUTPUT jack is separately protected by an automatically resetting fuse. A power LED is associated with each OUTPUT jack, facilitating identification of wiring faults. Module power is indicated by a front-panel LED.

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.
