HALO SERIES - MULTI-CHANNEL AMPLIFIERS

PARASOUND

HALO A31

3-CHANNEL AMPLIFIER, 400 Watts x 3, 4 Ω

The A 31 was designed in response to increasing demand for a three channel power amp that holds nothing back in power or performance. The A 31 is identical in performance and sound to the award‐ winning Halo A 51. 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 backchannels 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 center 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+ mono blocks. 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.
