Brand new, never used. One Acoustic Revive RIO-5II Negative ION Generator (the current version). We opened the box for taking pictures only. Tourmaline is widely known to contain electric current (0.06mA) as the human and other living bodies. There are reports that tourmaline has the effect of improving water quality, the release of infrared rays and other effects. One of the effects that Acoustic Revive paid attention to is that tourmaline releases negative ions, which are the same as those released naturally in the world. These natural negative ions size is 10000/1 smaller compared with negative ion produced electrically. Natural negative ion penetrates more easily into human body and other material, compared with electrically made negative ion. This is how to use RIO-5II: place the CD or DVD etc. on top of RIO-5II, and press the red button. This will run the electric fan about for 8 seconds, which irradiates the surface with natural negative ions on to the disc. Other than negative ions, RIO-5II also emits infrared rays which activate the surface of the disc and improves the transmission of the laser beam to the disc. After treating both sides of a disc, the sound and picture quality will dramatically improve. S/N ratio and dynamic range are improved and all instruments and vocals become vivid fresh. On the picture, it gives depth and excellent color contrast. If you place RIO-5II and switch it on in your listing room, the natural negative-ion released by the halogen lamps ray and heat fills the room up. This ion will purify the air in the room, and sound waves travel more smoothly, resulting in improvement of sound quality. A higher effect is provided when you use RIO-5II together with the audio demagnetizer RD-3. Retail price is 1.150 euro, now for 749 euro only. Check our other listings for more interesting items.
