Power Amplifiers - Two Channel Low Impedance
Peavey IPR amplifiers
Boasting a net weight as low as 3.2kg, the ground-breaking IPR Series
utilises an advanced design that allows the engineers to dramatically
reduce weight while increasing output power, reliability and thermal
efficiency. IPR Series amplifiers are designed with a resonant switch-
mode power supply and a high-speed class D topology that yields
the highest audio resolution and efficiency available. And all at a cost
that shatters the old-guard paradigm of power-amp valuation.
Coming in 2012, The IPR DSP Series amplifiers feature the same
power ratings, design and efficiency, plus a 32-bit processor with
a suite of delays and crossovers, pre-programmed loudspeaker
settings, stereo/mono operation, lockout--and for the first time in
any power amplifier, built-in Waves
