Bakoon Products SCL CAP-1007 Small Preamp

Bakoon ProductsThe CAP series, which produces high-quality music life with just-fit size, was born in a narrow space. In order to play music information without excess even small volume in one room that neighboring neighborhood worriesBakoon ProductsWe generously invest our proud SATRI circuit technology. CAP-1007 is an amplifier that adjusts the volume by selecting many audio signals such as TV, CD player, DVD player, tuner, mobile prayer, smartphone, etc. It is a necessary amplifier for those who have a lot of sources to listen to with audio devices and it is troublesome to change the wiring every time.

No return line control

The output uses a powerful buffer amplifier HBFBC to reduce sound degradation. More than 100 million relays are used to select signals. Frequency characteristics are also guaranteed up to the MHz band, so there is no deterioration of the signal. When the distortion factor changes due to the frequency change, coloring is felt and the sound feels habit, but in CAP-1007 there is almost no distortion change from 20Hz to 50KHz. This shows how CAP-1007 is an honest sound without coloring.

Full Input System

INPUT SELECTOR is equipped with 6 systems and switches the input signal. From INPUT1 to 4, the rear RCA pins, INPUT5 and 6 are phonjacks on the front and rear panels respectively. The front panel phone jack is convenient for connecting signals of mobile devices such as smartphones.

If the gain of the power amplifier is maximized, the volume of the speaker can be controlled by preamplifier. With the CD player and DVD player on hand, you can switch the music source and control the volume at hand.

Noiseless with mobile battery drive

DC5V INPUT uses the supplied USB cable. A USB charger or a mobile battery can be used as a power source. Serious current consumption is 5V250mA, so a battery of 10AH can be used for 40 hours. Using a mobile battery does not affect noise, so CAP-1007 can operate at its best.

To the New Face

A new face. The CAP series uses commercially available general-purpose products to reduce prices, but this time by integrating knobs with advanced grade productsBakoon ProductsWe are trying to improve the sense of unity and texture.

Even though there are 6 types of inputs in body size less than 20 cm, they are well organized. It is super lightweight with 470g, but can be operated comfortably other than because the rubber grip at the foot is firm. Together with the power amplifier CAP 1001, it is a little bigger tapper, so the choice of installation place increases, and the luxury that troubles...
Other than turntables, you can enjoy music sufficiently by connecting directly with the power amplifier, but I think that the sound is better if you go through CAP-1007, because there is no sound deterioration or distortion by adopting buffer amplifier HBFBC etc. By using the battery, it may be large that it is released from power noise. It is unmistakable that it is not using an oversized speaker, but there is no strange habit, it is able to listen to sound that is clear and transparent forever,Bakoon ProductsThe lineage.
I listened to the battery-powered preamplifier CAP-1007 alone, but it was high S/N that surpassed the ultra-high class preamplifier, and the sound quality was very fresh. With a natural texture that does not feel coloring at all, the dynamic range and frequency range are wide, and it is a clear, crisp and stretched true sound from large signal to weak signal. Power amplifier CAP -1001 has a low input impedance of about 10KΩ, so if you use a sound source device using an op amp IC for the output circuit, you may not be able to demonstrate this domain due to lack of drive capacity. However, when the high input impedance intervenes the CAP-1007 with high drive ability, the sound quality changes, and the instantaneous power extends and stretches, but it becomes a clear and vivid playback sound. The speaker used a 8Ω of 91dB/W/1m and efficiency KEFQ950, but because it is a soft distortion characteristic, there was a volume that could not be thought of as a 6W/ch amplifier. The CAP series demonstrates that even small, lightweight and affordable amplifiers can achieve high sound quality.
