The Kojo Crystal C1P is a power strip with a surge absorber(lightning protection) and noise filter. Compared to its predecessor, the ForceBar S1P, Kojo has redesigned the noise filters, component selection, constants and layout to further improve sound quality.

> Surge Absorber + Noise Filter
The Kojo Crystal C1P uses Panasonic surge absorbers*1 which are highly reliable against lightning, with parts selected to meet 7KV. In addition, the noise filter part has been redesigned from the one equipped with Force barS1P, and the filter circuit configuration, component constants, and pattern artwork have been redesigned from the beginning. In this Krystal C1P, the common mode choke coil used in force barS1P was abolished, and the choke coil corresponding to normal mode noise was changed. A π filter is configured in combination with a capacitor.among them, normal mode choke coils are originally designed by our company, and we adopt air core coils*2 with large power resistance and unsaturated characteristics. in spite of the material of the winding material used for the air core coil, we select and manufacture good materials in both safety and sound quality from several types of winding material candidates.in addition π the capacitors that make up the filter adopt okaya electric’s noise suppression capacitor, which has a proven track record in our products. constant settings, including the inductance value of choke coils, are implemented from both auditory and filter characteristics.

> M.I.S.(Mechanical Isolation Structure)
The body consists of three parts: a TOP cover, a BOTTOM chassis, and a SUB-chassis. All interior components, from inlet to outlet, are mounted on the sub-chassis and suspended away from the exterior case (TOP cover, BOTTOM chassis) to isolate them from undesired external vibrations. The coupling material between the top cover and sub-chassis is also improved from titanium to M2052 alloy which effectively attenuates vibrations over a wide bandwidth, from low frequencies to ultrasonic frequencies. The M.I.S. design also ensures physical isolation from the exterior case even when an over-sized power adapter or power plug is used.

> New Material Design for Enhanced Stability
The top cover has been changed from steel to aluminum, and the bottom chassis and sub-chassis from aluminum to steel, resulting in an increase in weight of 10%. For better protection against vibrations from the floor surface, Kojo has increased the thickness of the bottom chassis from 1.6 mm to 2.0mm, and replaced the original rubber material with TAOC vibration absorption pad. These material improvements effectively enhances the rigidity and stability of the Kojo Crystal unit, giving you superior audio performance.

> Improved Internal Wiring
The internal wiring material has been improved from 4N oxygen-free copper to tin-plated 1.6mm while retaining the single-wire design that exploits the skin effect. It is also straight-wired to ensure no-loss power transfer. The board composing of the surge absorber and noise filter is designed to accommodate straight wiring. The board is a double-sided design to suppress noise and lower resistance, resulting in greater current flow. The solder material is chosen after a detailed research process and applied by Kojo’s skilled masters.

> Excellent Expandability
The Kojo Crystal C1P inlet and connecting outlet are based on the IEC60320 international standard to support expansion with compatible Kojo products such as the Crystal3.1/6.1. When combined as such, the Crystal C1P also provides noise filtering for the Crystal3.1/6.1.

> Digital/Analog Separation
The Kojo Crystal C1P can be combined with the Kojo Crystal 3P to provide digital/analog separation, by connecting the digital equipment to the Crystal C1P and the analog equipment to the Crystal 3P. The Kojo Crystal C1P comes with two interlocking bars to secure the junction where the units are connected. The compact and slim body design facilitates installation in limited spaces and tidy wiring. It also comes with a ground terminal on the top chassis, an unique feature not found in competing products, which can be used in conjunction with the 2-pin outlet to provide grounding.

> Design Philosophy
As the name implies, the Kojo Crystal series is designed around a clean and elegant theme. The chassis has been changed from the previous Kojo Force Bar’s black to silver. The bottom chassis creates a sense of unity with the top cover. The icon design complements the clean modern design while describing the surge absorber and low-pass filter electrical functions. The font has also been updated to better match modern styles. You can also look through the unit to glimpse at the M.I.S. design.
