From Japan to the world: Powersoft promotes the global phenomenon of listening bars
With increasing frequency, Capitals around the world copy a business model that is increasingly successful in Japan: los listening bars, which offer a high fidelity sound experience both in a relaxed daytime environment and in other types of nighttime contexts. The amplifiers Powersoft they give life to Toner, one of these businesses located in the city that saw the birth of the phenomenon: Tokio.
Toner, café-bar and collective space located on the banks of the Meguro River in Nishi Gotanda/Fudomae, Shinagawa-ku, Tokio, has updated its audio infrastructure with a suite of amplifiers and control solutions Powersoft. The installation includes the Quattrocanali 1204 DSP+D, the Middle 604 AD, the Middle 322 AD and a wall-mounted WM Touch control panel, all of them from Powersoft.
The establishment, whose name comes from the ink cartridges used in professional printers, reflects the idea that each visitor brings their own unique color to the premises. Based on the concept of “weaving and joining”, he local hosts a wide range of activities: from a casual daytime coffee service, even private events, pop-up shops and nightlife with DJs. Given the diversity in the use of space, It was essential to achieve clarity, flexibility and ease of use at all levels of music listening.
To design a system capable of satisfying these varied demands, Toner teamed up with Audio Brains. In collaboration with respected Osaka electronic musician and producer Aoki Takamasa, the team developed an audio solution specifically adapted to the needs of the venue. In the words of Yamazaki Junta, responsible for the integrator: “The end customer wanted an audio system that provided total tonal balance. Had to be prepared to play background music at low volume during the day, but it also had to be able to play high energy DJ sets, so Powersoft amplifiers quickly revealed themselves as the best option for this project.. Besides, They complement any speaker we pair them with.”.
The key equipment of Toner
The core of the installation is the Powersoft Quattrocanali 1204 DSP+D, a four-channel class D amplifier. Powered by Smart Rails Management (SRM) de Powersoft, The amplifier maximizes efficiency by dynamically optimizing power consumption, while reducing thermal dissipation.
Complementing the Quattrocanali are the amplifiers Mezzo 604 AD y Mezzo 322 AD, which provide additional flexibility thanks to their compact format. El Mezzo 604 AD offers four amplification channels with a total power of 600 W, while the Mezzo 322 AD offers two channels of 160 W, along with additional line level outputs to expand routing options. Half-rack design simplifies installation, allowing Audio Brains to integrate powerful amplification in a small space.
This deployment is completed with the WM Touch, a touch screen controller 4,3 inch wall-mounted is powered entirely through a single Ethernet connection. The solution provides an intuitive interface for staff to manage volume levels and system behavior throughout the day. Before final delivery, The team carried out a test session 13 hours long to make sure the configuration worked as intended.
The impact of the new system has been obvious for both staff and visitors. Whether providing subtle background music or lively and energetic DJ sets, Powersoft system maintains clarity, precision and control throughout the venue, explains Yamazaki: “Even customers who don't know anything about audio equipment say the sound has a new clarity. They are surprised that, even if the volume is quite high, “They can continue talking to each other without having to raise their voices.”.
