The Powersoft X Series integrates a large amount of functionality, generally only found in separate outboard units. This includes an innovative system of channel routing, a truly universal mono, bi and three-phase balancing power supply and a fully-featured DSP.
At the Prolight + Sound show
2014 in Frankfurt, Powersoft debuted its X series of power amplifiers. Designed to mark another evolution in pro-audio amplification, much as the seminal K Series did back in 1995 when technologies such as Power Factor Correction (PFC) and switch-mode amplification were introduced for the first time into the professional audio industry, the X series provides versatility, flexibility and power without compromising on size, efficiency and audio quality.
The X Series consists of two models. The X8 is the largest amplifier in the range, boasting eight channels in a 2U chassis, while the X4 features four channels in a single rack unit. Both models share the same power density, being capable of delivering up to 5200W at 2 ohms per channel.
Suitable for both low and high impedance applications, the Powersoft X8 and X4 are equally suitable for concert touring and professional fixed installations. The modular construction permits the rear input/output connections to feature either XLR, speakON or Phoenix connectors, depending on the requirement of the specific application.
“The philosophy behind the X Series is to permit the audio system to operate independently from the power mains available at the venue and to allow even smaller racks to be brought to run the show,” explains Luca Giorgi, Pro Audio Business Unit Director at Powersoft. “This brings us even closer to complete integration of the system and provides an unmatched level of control over the behaviour of both the audio and power source.”
The truly universal power supply has worldwide AC acceptance and allows direct connection to any regional power line configuration. Ultimately flexible and safe, Powersoft’s legendary and reliable power supply is now suitable for Single Phase, Bi-Phase or Three Phase operation from 85 V AC up to 440 V AC without the need for manual selection. True Three Phase load balancing is directly achievable by the unit without any complex load assignment in the power distribution system design. Neutral connection is not necessary given the capability of the unit to work in delta connection on Three Phase Systems. The power supply also features full Power Factor Correction as well as Powersoft’s patented Smart Rails Management technology, ensuring that the X Series runs as cool and efficiently as is currently possible.
Managing power with Powersoft X4 and X8 is easy thanks to the integrated low latency DSP providing high quality in signal processing as well as a complete routing and mixing of the input/output channels. Signal management and processing architecture on the Powersoft X Series is composed of six separate sections: Input source selection; Input processing; Matrix; Pre-output processing; Speaker routing; Output processing.
The X Series natively supports AES3, two redundant Dante by Audinate digital streams and analogue inputs, providing up to four different selectable input sources per channel.
The set-up parameters of the Powersoft X Series are fully integrated into Armonía Pro Audio Suite which offers an intuitive interface for parameter adjustment, a comprehensive control over the digital audio processing and complete real-time monitoring of the system performance. An integrated WiFi connection permits the Powersoft X Series to be accessed and managed via any smartphone or tablet through a user interface specifically developed for local monitoring.
“Our sights have been fixed firmly on the future during the design of the X Series,” states Claudio Lastrucci, Powersoft R&D director, “We looked at what we believe amplifiers will require for the next 10 years and made a platform capable of meeting these needs as well as building in a certain level of ‘future proof’ expandability.”
