model S506 "switchgirl" ― Smart Input Selector

Long life, high reliability reed switch (contact: ruthenium) is used.

When used in combination with a power amplifier model S505/S505i, with this input selector, you can switch three music sources. In switching signal systems, adopting a long life, high reliability reed switch (contact: ruthenium) in which an inert gas is sealed in the glass tube, the deterioration of freshness is very low. It is a high purity input selector which is almost indistinguishable from the direct connection without any inclusion between the music source and the power amplifier. Besides conventional voltage-mode signaling type, current-mode type can be selected. You can purchase it separately so that it can be used even in combination with other systems.

How does the voltage-mode and the current-mode signaling works?

By adopting the principle superior current-mode signaling in exchanging music signals, it is progressing dramatically from the conventional audio system. By simplifying the conventional voltage-mode complex equipments, the purity of the music signal has been dramatically improved.

Features

Smart Size ― Easy to wiring from rear panel.

In size-held (100×200mm) in one hand, you do not choose a place to put it. Since the depth is narrow, it does not get in the way routing of the wiring from the rear panel.

Monotone Finish — We strictly enforced basic performance.

The "switchgirl" means telephone exchange lady at an old time, the top plate in 5mm thick acrylic, this model has gray-smoke monotone panel only.

Simple Front Panel — Easy to operate.

We think that the devices for listening to music should be as simple as possible. For that reason, we designed as soon as possible to immerse into the music by losing cumbersome switches as much as possible, just plugging in the cable and turning on the power. The operation switches are input selector and mute/play only.

No Habit Sound Quality ― Thoroughly eliminate the element that causes the stagnation of the music signal.

We studied something that causes stagnation of music signals deeply and put a scalpel on them. There are connectors and terminals with many metal parts, conducting wires plated and excessive amount of solder as major factors. By thoroughly eliminating these, the balance of the tone range has been adjusted, the hysterical feeling of jogging in the high frequency range and the electronic equipment odor accompanying sound with habit are gone, and it is finished to the "elegant" tone quality never before by nature It was. It is an input selector which is more pure than almost any direct connection without any inclusion between the music source and the power amplifier.

All Stainless Steel ― Good quality music dwells in a sturdy structure.

Including the chassis, spacers, bolts and nuts, all have adopted the stainless steel. Among the metal, stainless steel rigid vibration transmission speed (about 5740m / sec.) is comparatively faster. Not accumulate the vibrational energy to the chassis, the mechanical ground of the vibration that quickly performed, was to further improve the expressive power of a fine sound. In addition, the electrical resistance (internal loss) of stainless steel is larger than that of the copper and aluminum (about 429 times that of copper), to absorb the electromagnetic noise from the internal circuit and external environment, there is also the advantage of easily consumed as heat. In this way, we are contributing significantly to the low noise of the material of the chassis.
