~acus sound engineering~ At acus, all of our equipment, including amplifiers, cabinets, and PA systems, is handmade and specially designed for acoustic performances. Everything from the speakers to the internal electronics is custom made, and ACUS engineers have planned and designed everything from the internal structure to the finest specifications to ensure the optimal sound range is output for the acoustics. For over 40 years, acus has been committed to producing equipment that reproduces pure, natural sound, and has been manufacturing acoustic-specific equipment in Recanati, Italy. It has been highly praised by many musicians, especially in Europe, for its high sound quality and design. ~ONE FOR STRINGS~ The ONE FOR STRINGS series was developed to output the sound produced by all acoustic instruments with as natural a tone as possible. It delivers excellent performance, especially with acoustic and classical guitars, including full-acoustic and semi-acoustic guitars. The speakers, chassis, equalizer, etc. are all designed and manufactured in-house, and are carefully designed to amplify natural tones. In addition, the line out, microphone input, and auxiliary input, which are essential for an acoustic amplifier, are all located on a stylish control panel with original knobs. This makes it a highly versatile acoustic amplifier that can also be used as a mini PA system depending on the situation. ~ONE FOR STRINGS 8Ferdi~ The ONEFORSTRINGS 8FERDI is a compact band amplifier with a maximum output of 140W, and features three independent inputs as well as TRRS audio inputs and outputs, each with its own independent volume and 2-band EQ. All input channels feature gain, 3-band EQ, effects and volume controls, and input 1 in particular is equipped with a compressor and a switch to change the channel characteristics to suit the type of instrument connected. There are three switching modes: Flat: Standard equalization suitable for acoustic and classical instruments. Same characteristics as channels 2 and 3. Bass: For instruments with a distinctive low range, such as electric bass, acoustic bass, and double bass. Jazz: Best setting for electric guitars and semi-acoustic/jazz guitars. *The image is a sample.
