Legacy Audio Powerbloc2 ULTRA Dual Mono Amplifier

Description

PERFORMANCE COLLECTION

Powerbloc2 ULTRA

Legacy’s PowerBloc2 ULTRA is a dual monoblock design
offering independent power supplies doubling the current capability of
the PowerBloc2. With the added heat sinking of separate ICEpower modules
each channel can deliver peaks of 1000 watts into speakers like Focus SE.
In fact, these are the very same high current modules found in a pair of the
incredible Focus XD.

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 ULTRA 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 ULTRA 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 ULTRA 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 ULTRA 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 ULTRA provides serious power… for
serious listening.

The Powerbloc2 ULTRA is also available in a lower output
version- the Powerbloc2, and 4 channel version, the Powerbloc4.

“The promise of serious power at a fair price is
honestly made and fully delivered.” – Dan Kumin, Sound & Vision

Award-Winning Design

The Legacy Powerbloc2 ULTRA 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 ULTRA 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 ULTRA a closer look
and listen. Your speakers will thank you.” – Jim Milton, Secrets of Home
Theater & High Fidelity
