The Legacy Audio Powerbloc4 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, Powerbloc4 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 Powerbloc4 can be used in pairs with Legacy Audio's DSP based processor/crossovers to bi-amping speakers and to raise system performance to a new level.

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 Powerbloc4 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.
