Description
The RMDA series of 19” rack mount amplifiers are completely self-contained broadband distribution amplifiers, designed specifically for signal distribution systems requiring the low distortion characteristics only available using hybrid CATV integrated circuits. Useful either in systems which use a “cable drop” as a signal source or as the launch amplifier in a headend, these amplifiers are available in various gain versions with four different bandwidths, 47 to 550 MHz, 47 to 750 MHz, 47 to 860 MHz or 47 to 1000 MHz.
These amplifiers are available with one or two hybrid amplifier gain blocks. The use of two gain block units with interstage controls provides superior noise performance along with an extended range of gain and slope. The single gain units provide good electrical performance at a modest price. The combination of these two architectures in the RMDA line results in models with a wide range of performance features to satisfy simple or stringent applications.
The series provides flat operating gain which can be reduced with a variable attenuator. Gain and slope controls are located on the front panel for fast set-up and adjustment.
Two 20 dB test points are provided to permit testing without interruption of service.
Hybrid IC modules enable the RMDA to operate at high output levels while retaining low distortion characteristics.
The aluminum chassis is designed to provide excellent heat dissipation, thus allowing operation at high ambient temperatures with no degradation of performance or reliability.

NOTE TO CATV SYSTEM INSTALLER
This reminder is provided to call the CATV System Installer’s attention to Article 820-40 of the NEC that provides guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entry as practical.
IMPORTANT SAFETY INSTRUCTIONS
1.Read these InstructionsAll the safety and operating instructions should be read before this product is operated.
2.Keep these InstructionsThe safety and operating instructions should be retained for future reference.
3.Heed all warningsAll warnings on the product and in the operating instructions should be adhered to.
4.Follow all instructions-All operating and use instructions should be followed.
5.Do not use this apparatus near water-for example, near a bath tub, wash bowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool, and the like. Refer to individual instruction manuals included with products designed for indoor use only. Do not expose these products to rain or moisture.
6.Clean only with a dry cloth-Unplug this product from the AC power outlet before cleaning.
7.Do not block any ventilation openings-Install in accordance with the manufacturer’s instructions.
8.Do not Install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.
9.Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the third prong are provided for your safety. If the provided plug does not fit into your outlet, consult and electrician for replacement of the obsolete outlet.
10.Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles and the point where they exit from the apparatus.
11.Only use attachments/accessories specified by the manufacturer.
12.Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.
13.Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
