The company has announced the introduction of the new IPR Series of ultra-lightweight and efficient power amplifiers, reports David Davies. Featuring a net weight of 3kg on its lightest model, the IPR Series utilises an advanced design that allows Peavey engineers “to dramatically reduce weight while increasing output power, reliability and thermal efficiency.” The first model in the series, the IPR 1600 (pictured), is available to order now and offers 800 Watts RMS per channel into 2 Ohms and 530 Watts RMS per channel into 4 Ohms. Designed with a resonant switch-mode power supply and a Class D topology, the IPR Series amplifiers feature two channels with independent 100 Hz crossovers and a variable-speed fan housed in a lightweight aluminium chassis. Peavey’s exclusive DDT speaker protection with multi-point clip sampling leads a protection circuitry suite that also includes DC, Temp, Signal and Active safeguards, all referenced on the front panel with LED indicators. Speaking to PSNE, Eric Lund, international sales manager of Peavey and Associated Brands, says that “the major, unique difference with this particular Class D technology compared to earlier designs is in two areas. 1) The impedance of the output devices in the ‘full on’ mode is 0.02 Ohms compared to previous MOSFETs at around 6 Ohms so the power, and hence heat dissipation, in the devices is dramatically reduced resulting in cool running and much-reduced requirement in the number of output devices needed. Also, [there is] a superior performance when used to power low impedance loads (2 Ohms). 2) The output switching circuit (chip) is much faster, resulting in reduced time in the output devices’ ‘part on’ mode, again reducing power in the actual devices.” In other Peavey news, company founder and CEO Hartley Peavey was the recipient of the 2010 MIPA Hall of Fame Lifetime Achievement Award, which was presented during the Musikmesse International Press Awards in Frankfurt, Germany. One of only ten other figures honoured with the award – previous recipients include Roland Corporation founder Ikutaro Kakehashi and Korg founder Tsutomu Katoh – Peavey paid tribute to the contribution of his development teams and asserted the company’s continuing emphasis on technological innovation. “The fat lady hasn’t sung yet with Peavey!” he exclaimed.

Power amps: 10 new chapters

The current popularity of powered loudspeakers might lead some observers to predict a long-term decline for standalone amplifiers. But by nominating 10 exciting new developments in independent amps, David Davies thinks he has proven that any such claims are extremely wide of the mark…

Power amplifier manufacturers are using new energy-saving techniques to make their products more efficient, environmentally friendly and easier to transport. Simon Duff looks at some of the trends and manufacturers that are making a difference.


InfoComm 2013: Amps back on the map at QSC

QSC has launched two new power amplifier families at InfoComm 2013 – PLD and CXD. The PLD family is for portable live sound reinforcement, while CXD amplifiers are designed to meet the needs of integrators, The two ranges share a common four-channel Class-D platform.
