The Legacy Audio Powerbloc2 is a musical reference and studio workhorse dual mono 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 is also available in a 4 channel version, the Powerbloc4.
Less Wasted Power
Power loss of the Powerbloc amplifier and power loss of a Class AB amplifier with highest theoretically possible efficiency.
Award-Winning Design
The Legacy Powerbloc2 is the recipient of both a Sound & Vision Magazine Top Pick Award and a "Thumbs Up" Award from Secrets of Home Theater & High Fidelity.
"All the power most will ever need, with the sound quality you want in a slim, cool-running package." - Dan Kumin, Sound & Vision
"The Powerbloc2 had finesse and muscle, imaging was excellent, and it had complete control of my speakers, allowing me to hear what they can do. If you are in the market for a two-channel sound system and you want these qualities in your sound system, give the Legacy Powerbloc2 a closer look and listen. Your speakers will thank you." - Jim Milton, Secrets of Home Theater & High Fidelity
