What is Attenuator?
Attenuator (ATT) is a resistance attenuator. It is like a volume, and the level of sound (strength) changes to +/- by turning it right and left. Continuous variable or decibel scale step expression.
Role in Speaker
The product page of the speaker is here
The speaker attenuator is used to flatten the characteristics by filling the level difference between the configured units such as woofer, scorker and tweeter.
Speakers are usually designed for woofers, and scokers and tweeters are designed to increase efficiency, so attenuators are included to adjust the level of scokers and tweeters. You can adjust the level between units to your preferred level according to the state of the room and the music genre you watch.
In recent speakers, the type adopted seems to be limited, and I do not see much. As is the case with the manufacturer handled by our shop, it is unnecessary because the tuning of sound with network circuit is done with high precision inside the speaker.

In addition, the other attenuator is used as a volume circuit for amplifier, and the amplifier has been removed from the amplifier for "passive attenuator," especially for equipment that sticks to sound quality and volume adjustment function.
The amplifier is generally a volume adjustment function, so it seems to think that the volume changes somehow high, but the attenuator is excellent that the sound changes dramatically just by changing here.

By adopting the attenuator in the volume part of the amplifier, it is possible to play high-definition and high-precision sound than the volume circuit used normally, providing elastic and expressive music. The accuracy of the playback sound also changes depending on the precision of the resistance.Bakoon ProductsAs in the amplifier series, from the standard specification volume, optional, low current noise, metal film type resistance with good accuracy and excellent characteristics, and a non-inductive wire resistance that greatly reduces the occurrence of parasitic inductance, which causes distortion of signal waveform (linking) on the amplifier internal circuit with magnetic flux. If the resistance is accurate, the amount will increase, but it is better to choose depending on the music genre you like.

"Passive Attenuator" is a device with a very simple volume adjustment mechanism, with only passive/passive elements, without using amplification elements such as vacuum tubes and transistors to convey sound signals to speakers and power amplifiers on amplifiers. Since there is no need for power, there is no amplification circuit, so there are many cases where the low range is slim by pressing, but the passive attenuator that is compiled to the minimum is enough even if it is subtracted, the freshness and resolution of the sound, the high range of vivacity and the amount of information and the good to escape The preamplifier has a good appeal.
The violin and classical guitar strings show a single-tone detail, expressing the variation of the piano player's fine touches, such as the absence of wind instruments. The light tone and moderate low range are comfortable to listen to, natural, delicate, and high-freshness passive attenuator is especially recommended for those who listen to classical music mainly in small composition or solo.
