Lead, iron, reduce the impurities that cause turbidity of the sound, such as cadmium to the limit, use high purity brass that has been optimized for the acoustic "Crystal Brass" the (RoHS compatible) to the main body material. While attenuating the unnecessary vibration, it does not impair the sound and sense of movement required for the music.

On the side shape of the insulator, it adopted a "4 slant style" composed of a taper angle of the four-stage, high-precision cutting by computer-controlled NC. With disperse a simple natural oscillation mode that tends to occur in a cylindrical shape, by the easy-grip ergonomic design, it facilitates adjustment of the position of the insulator in the gap under the narrow equipment. In addition, both the stylish design.

By performing a "half-bright chrome plating" (thin satin finish + chromium plating), it made the surface more rigid. Thus, the improvement of the durability, while reducing the distributed control of the vibration mode, was stuck by the beauty of shiny texture to semi-gloss.

Use of carbon FRP plate on one side of the insulator. It aims to stabilize the contact surface, and then directed to the Crystal Brass unwanted vibration at high speeds. In addition, so as to be 0.01 mm projecting the carbon FRP from the body, exactly fitting bond the carbon FRP to the body. As a result, without damaging the contact surface, only carbon will contact the contact surface.

One side to φ20, providing a dent of depth 4mm, can snap the INS-CF here. And improvement of the overwhelming S / N ratio, it is possible to add a sense of high-speed.

Place the hole (φ5) for screwing to the central axis. Remove the accessory insulator of equipment, replace the INS-BS, was it possible to screwed (used in the carbon surface to the equipment side). The exchange with the accompanying insulator, equipment and INS-BS can be in direct contact, The new model further improvement in sound quality.

Be down even if on the carbon surface, either can be used reversible specification. Enjoy the change of tone (in INS-BS alone use, if you do not screwed to the instrument).

INS-BS screws can be fixed

The INS-BS can be screwed in MTB-4 / MTB-6 / MTS-6 and OCB-1 series (later Ver.2012). MTB-4 / MTB-6 / MTS-6 can be attached to INS-BS in M4 screws from Remove the brass spike (OSP-SC). OCB-1 series can be attached to INS-BS via the M4 screw into threaded holes in the bottom four corners.

(M4 screws and drivers needed for installation, please bring your own.)

Note: If you are screwed to the device, the device comes with insulator is in screw-type, and please confirm or removable.Screws, please use the length of 5mm or more bind screw or Nabeneji. In the case of short screws that can not penetrate the screw holes (less than 5mm), there is a possibility that can not be screwing this product to the equipment. 
If you are installing the OCB-1 series Ver.2012, please use the M4 size of the screw. 
In addition, the screw head size is small, if you become depressed in the hole of this product, please in combination washer.It should be noted, does not come with a screw and washer is in this product.
