Low-frequency amplifier RU4-29 (RU429, RU 4 29, RU-4-29, py4-29, RU4 29, RU-429, RU 429, py429, py 4 29, py-4-29, py4 29, py-429 , py 429)
Low-frequency amplifier RU4-29 an ac amplifier with built-in acoustic filters.The device is intended for research, testing and configuration of systems and devices used in electronics, communications, automation, computing and measurement techniques, priborostrenii.
To enhance performance and functionality of the amplifier RU4-29 does not have a rigid setup of the gain.
The whole amplifier channel amplifier subwoofer unit RU4-29 is divided into two parts, each of which has an independent set of the gain.In the gap between them is included, or any of the internal filter or external filter.
Such a construction allows the amplifier to create optimal conditions for measuring the dynamic range and signal-to-noise ratio.
