The Parasound HALO A31 multichannel amplifier is a power amplifier that draws directly from the hefty lineage of the 5 channel A51. Like it's bigger brother - the it's also a THX Ultra 2 certified product, but the interesting backdrop to the A 31 is that it was designed in response to increasing demand for a three channel power amp that holds nothing back in power or performance.
Here are a few of the many applications for the A 31:
1) To power the front three channels of a home theatre. The surround or back channels can then be powered by a smaller 2ch Parasound power amp such as the Halo A 23. This gives the greatest power to the front channels where it is needed the most.
2) To power the centre channel and two surround channels. This allows the Left and Right front speakers to be powered by a dedicated two channel power amp such as the Halo A 21, or better yet, two JC 1 monoblocks. This is ideal for the music lover who is unwilling to compromise stereo reproduction.
3) To power the front three channels in an AV receiver‐based system. The remaining surround and back channels can be driven by the receiver. This assures you the best sound for the front channels while enabling the AVR to produce more power for the surround and back channels. However you employ the A 31, you will be delighted by its impeccable sonics, striking authority and faithful reproduction of the smallest details.
