About the Halo P 3

The Parasound Halo P3 is a high-quality stereo preamplifier designed for audiophiles seeking excellent sound performance and versatile connectivity. It includes six line inputs, one of which can be switched to a moving magnet (MM) phono input, relay-switched direct inputs for balanced and unbalanced connections, and both balanced XLR and unbalanced RCA outputs. The unit features a vacuum fluorescent display, defeatable bass and treble controls, a high-resolution stereo headphone amplifier, and an external processor send/receive loop. It also supports RS-232 control, external IR input and loop output jacks, and two 12V triggers for system integration. The P3 is housed in a robust 2U chassis with rack mounting options and includes a remote control that also operates the Parasound Halo T 3 tuner. Internally, it is powered by an enormous encapsulated toroidal transformer and uses dual-layer glass epoxy circuit boards for durability and performance. The preamplifier supports switchable voltage operation (110-120V or 220-240V) and weighs approximately 16 pounds. It was manufactured from 2002 until it was discontinued, and it remains a respected choice for its combination of features, build quality, and sound performance at a competitive price point.
