More info

he Roland AC-40 is a portable, light and powerful amplifier, with a very natural acoustic sound, for electroacoustic guitars and voice.

The Roland AC-40 is a very powerful portable amplifier, perfect for musicians looking for natural and reliable amplification. It is the latest model in the Roland Acoustic Chorus family, recognized for its clean, loud and natural sound for acoustic instruments. And it is very practical, with two channels for guitar and microphone, combining versatility and high quality in a compact and affordable unit.

The two 17.5 watt speakers deliver rich, pure stereo sound, true to the characteristics of acoustic instruments, and with a defined and present projection.

Roland's DSP technology, in addition to raising the sound quality, allows the application of effects that give it another dimension, such as a multi-band chorus with "Wide" mode, reverb, and 3D ambient effects created especially for acoustic guitars .

The Roland AC-40 was also made to amplify the voice. Connect a microphone to the Mic / Line channel and sing, with independent volume control, equalization and chorus. They can connect an mp3 player for richer accompaniment. The controls are simple, very direct and are clearly identified, in a top panel of easy access and visibility.

Bearing in mind that electroacoustic guitars are easy to get feedback when amplified, the Roland AC-40 has a function that reduces that risk so that they can act without worrying about unwanted sounds.

Very practical, resistant and easily transportable, the Roland AC-40 weighs just over 5 kilos and also has a support to raise the angle of the sound projection, so that they can take better advantage of the acoustics of the place where they will perform. Or, to serve as a personal monitor embedded in a larger amplification system.

Roland is one of the leading brands in the music industry, with almost 50 years of history in the manufacture of amplifiers, effects pedals, rhythm boxes, electronic drums and synthesizers.

The Roland AC-40 was made for those who like to perform at any time, with great fidelity, sound quality and extra functions for creative and versatile performances, in relaxed settings and for professional use.
