Ooberpad proudly presents to you the dynamic Parasound Halo A 31 Three-Channel Power Amplifier. The Parasound Halo A31 multichannel amplifier is a power amplifier that draws directly from the hefty lineage of the 5 channel Parasound Halo A51. Like its bigger brother - it's also a THX Ultra 2 certified product, but the interesting backdrop to the Parasound Halo A 31 is that it was designed factoring in the increasing demand for a three-channel power amp that packs a punch with power and performance. So the Parasound Halo A 31 is no less a winner in performance and sound to the award-winning Parasound Halo A 51.

                  Benefits of Parasound Halo A 31 Three-Channel Power Amplifier:

                  Interesting Proposition - Can be Subtle and Severe Just As Required
                  Interesting proposition

                  The Parasound Halo A31 is a perfect reflection again of Parasound's commitment to ensuring the best performance at many different price-points - but also a nod to real-world thinking and applications without compromising 'relative' performance in the context of smaller systems or applications. As the Parasound Halo A31 can output between 250watts to 400watts per channel - this is a real-world measurement as this is whilst all channels are being driven (20 Hz - 20 kHz - 60 amperes peak per channel). This high power and high current output performance deliver very flexible dynamic 'headroom', which is why the amplifier can be sublimely subtle when required, and unabashedly severe when raw power is required. Plus, remember that like the Parasound Halo A51, the Parasound Halo A31 also has a high bias class A/AB operation working along with its directly coupled design (there are no capacitors or inductors in the signal path). The Parasound Halo A31's high power and high current output performance deliver very flexible dynamic 'headroom', which is why the amplifier can be sublimely subtle when required, and excruciatingly severe when raw power is needed.
