Powerbloc4 is the 4 channel version of the acclaimed Powerbloc2. 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. Now, the Powerbloc4 provides the same performance across four channels!
The benefits of multi-amplication 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 to biamp passive speakers alongside Legacy Audio's DSP based processor/crossovers to raise system performance to a new level. They can also be used in high performance theater applications to power center and surround channels.
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
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.
The Legacy Powerbloc4 provides configuration flexibility with four channels of serious power... for serious listening.
