Unique, Innovative, Rarely Japanese Audio for Audiophile!!Famous, Historical, Vintage Japanese Audio Device!!Pursue the best sound in the near fieldI want to enjoy the best sound even in a single room!DescriptionFrom Bakoon Products, the CAP series was born to produce high-quality music life with just-fit size in a narrow space.In order to play without leaving any music information even in a small volume in a studio where neighbors are worried about, we introduce SATRI circuit technology of Bakoon Products' pride without regretting it.The CAP・1007 is an amplifier that selects and adjusts the volume of many audio signals, such as TVs, CD players, DVD players, tuners, mobile players, and smartphones.It is an essential amplifier for those who have a lot of sources to listen to in an audio device, and it is troublesome to change the wiring one by one. No feedback line controlThe output uses a powerful buffer amplifier HBFBC to minimize sound degradation.We use relays that have a mechanical life of more than one billion times for signal selection.The frequency characteristics are also guaranteed up to MHz, so there is no degradation of the signal.When the distortion rate changes by the change of the frequency, coloring is felt and I feel a habit in the sound, but in CAP-1007 there is almost no change of the distortion from 20Hz to 50kHz. This shows how CAP-1007 is an honest sound without coloring. Enhanced input systemThe input is equipped with 6 INPUT SELECTOR TO switch the input signal.INPUT1 to 4 are RCA terminals on the back, and INPUT5 and 6 are phone jacks on the front and rear panels, respectively.The phone jack on the front panel is convenient when connecting signals of portable devices such as smartphones. If the gain of the power amplifier is maximized, the volume of the speaker can be controlled by the preamplifier.If you put a CD player, DVD player and this unit at hand, it is convenient that you can control the switching of the music source and the volume at hand.Mobile battery powered and noiselessUse the included USB cable for DC5V INPUT.You can use a mobile USB charger or a mobile battery as a power supply.As the serious current consumption is 5V250MA, it can be used for 10 hours if it is a battery of 40AH.If you use a mobile battery, you will not be affected by noise, so you can operate the CAP-1007 in the best condition.
