About the RR-777

The Acoustic Revive RR-777 is a Schumann frequency pulse generator that emits a 7.83 Hz pulse intended to shield HiFi electronics and listening rooms from radio frequency interference, thereby improving the signal-to-noise ratio and overall audio performance. It is the successor to the RR-77, featuring about four times the Schumann pulse strength and an improved S/N ratio. The device is housed in a lightweight plastic chassis with an attractive silver finish and gold lettering, similar in size to the RR-77. It is powered by an external 12V power supply and is recommended to be placed at least 5 feet (about 1.5 meters) above the floor and away from audio equipment for optimal effect. Users have reported that the RR-777 enhances soundstage depth, imaging precision, and detail retrieval, with a brighter and more brilliant tonal balance. The unit can be tuned via its power supply, with different power supplies affecting tonal characteristics such as bass heft and high-frequency extension. The RR-777 is praised for making the sound more natural and reducing listening fatigue, with a noticeable improvement in musicality and acoustic space. It is used in professional recording and mastering studios and is considered a valuable accessory for audiophiles seeking to improve their system's performance.
