Parasound Halo P 7 Preamp Delivers Low-Noise Performance
Steve Crowe · August 19, 2008

Parasound is introducing its Halo P 7 preamplifier that is designed for low-noise performance from classic stereo sources.

The Halo P 7 is both a two-channel and 7.1-channel analog preamplifier that, Parasound says, can be an alternative to a surround processor if the TV used in the system switches video inputs and the user owns multi-channel analog sources.

It has analog bass management for stereo sources to enable subwoofer and small speaker integration. There is also volume control bypass for those who use home theater receivers to decode digital sources.

The Halo P 7 can switch 1080p HDMI sources when linked to the optional Zhd HDMI switcher. Parasound says the P 7’s noise floor is “a full 10 dB below that of a typical AV receiver.”

Halo P 7 can adjust left-right/front-rear balance, make custom input names and match the gain for all 10 inputs, including a front panel MP3 input.

Other features in the Halo P 7 include:

  • Balanced XLR connections
  • A low-noise MM/MC phono input and remote tone control
  • RS-232 control, discrete IR codes, IR repeater input/loop jacks and three DC triggers
  • Two buttons and one knob on the front panel to control most of the functions

The Halo P 7 is now shipping from Parasound Halo dealers for $2,000.
