POWERSOFT EXTENDS SIGNATURE K-LIGHT SERIES WITH K2 MODEL

ORLANDO, FL, June 17, 2009 – Powersoft Advanced Technologies, LLC, a world industry leading manufacturer of superior quality power amplifiers for the professional audio market, is featuring its new Powersoft K2 amplifier at InfoComm 2009 (Booth 6384). This new amplifier is an extension of Powersoft’s signature K-Light Series, which launched last year with the successful K3 model. The K2 is a power amplifier that meets the most stringent requirements of professional users in concert touring, sound reinforcement and professional fixed installations. Designed by Powersoft’s R&D team, the K2 is exclusively manufactured in Italy with internal components selected for premium quality and proven durability.

Featuring the same compact dimensions as the K3—a one-rack unit case, 360mm deep with a weight of 8 Kg—the K2 provides 1000W per channel with an 8-ohm speaker load, 1950W at 4-ohms and 2400W at 2-ohms in stereo configuration. Its bridge mode operation is 3900W at 8-ohms and 4800W at 4-ohms. Each modular subassembly is pre-tested, and the assembled K2 receives a rigorous 48-hour burn-in before final check-out on precision test equipment for total quality control.

The K2 incorporates the innovative and patented Powersoft universal switching mode power supply, providing users with worldwide AC operation in voltage ranges from 95 to 265V. The Power Factor Correction (PFC) technology employed in the design tolerates up to a 400 VAC spike without interrupting rated audio output and clarity. The design also features low power consumption with an incredible Power Factor efficiency of more than 0.90 from 500W to full power. This yields a 40 to 60% reduction in current draw over traditional power amplifiers without PFC, helping to lower the carbon footprint and delivering a sensible economic benefit for installations. These amplifiers pay for themselves over time through equivalent power savings.

Powersoft’s bridgeable switch mode fixed frequency class D patented outputs generate high-quality sound with an excellent damping factor and the amplifier circuits run cooler for stable performance over time, resulting in longer amplifier life and reduced external cooling costs. Both units feature an LCD display with lockable user menu for easy control of all settings.

Offering DSP for full high-quality, on-board sound processing with up to 16 EQ filters per channel, the K2 is equipped with FIR filters with a cross-over slope of up to 48 dB per octave. The DSP package is capable of up to two seconds of delay per channel for time correction between satellite speakers. The peak limiter and true power limiter functions offer complete loudspeaker protection, while the patented damping factor and cable resistance compensation network offers a tight low end that is independent from cable section and length.

The K2 comes with a sensing and communication board that uses a standard RS-485 bus and offers an optional Ethernet connection through Powersoft’s KAESOP board that is able to drive two AES3 channels over the same CAT5 cable. This provides full control and monitoring through proprietary software running on an external PC. The software is compatible with all other Powersoft K, D, Q and QTU Series amplifiers.

Offering a signal to noise ratio greater than 110 dB, the K2 offers a Total Harmonic Distortion (THD), SMPTE and DIM30 Inter-modulation that is less than 0.5% from 1W to full power (typically less than 0.05%). The K2 demonstrates top-class performance that is similar to the acclaimed K Series, which has been available since 2005 via the best rental companies worldwide.

Rear panel input/output connectors are based on XLR inputs with loop thru XLR and Speakon© output connectors, detachable and lockable AC mains IEC 20A connector.

Featuring a front panel smart card reader, the K2 provides firmware upgrade, preset load and save, which allows for step-up card processing for future upgrading to K3 power output achieving total flexibility.
