The Legacy Audio Powerbloc2 is a musical reference and studio workhorse two channel amplifier.
Incredible Performance in a Small Package...at a Fair Price.
Audiophiles will appreciate the detail and resolution from the ultra-wide 1.5 Hz to 70 kHz bandwidth. Professionals will love the abundance of effortless power. Characterized by a solid and taut low end with fully developed shimmer in the top extremes, Powerbloc2 is one of the most versatile reference grade amplifiers ever.
The benefits of multi-amplification are inarguable; lower intermodulaton, greater headroom and freedom from harmful clipping. Yet concerns over cost, bulk and complexity have prevented users from enjoying these substantial advantages. The Powerbloc2 can be used in pairs with Legacy Audio's DSP based processor/crossovers to raise system performance to a new level. They can also be used in pairs to bi-amp passive loudspeakers.
Numerous refinements to class D topologies in recent years have resulted in improvements that not only match the neutrality of other high end designs, but actually exceed typical performance parameters in several ways:
High damping factor
Low output impedance
Wide bandwidth
Huge dynamic range
Stable into low impedances, the Powerbloc2 achieves high output without bridging and is exceptionally quiet. No transformer hum, fan noise or long waits after power cycling for stabilization. Extremely stable even when driven hard, the ultra-efficient Powerbloc amps feature short circuit protection, thermal sensing and 12VDC triggering. Inputs are premium hand soldered XLR balanced and gold-plated RCA inputs, as found only on the finest gear.
The Legacy Powerbloc2 provides serious power... for serious listening.
The Powerbloc technology is also available as the dual monoblock Powerbloc2 ULTRA, or in a 4 channel version, the Powerbloc4.
