Parasound Zamp V.3 Two Channel Zone Amplifier

parasound zamp v.3

The Zamp V.3 is a stereo power amplifier which won “Product of the Year” 2009 from Positive Feedback Online. A powerful version of its ultra-compact Zamp zone amplifier for use in custom installations and compact systems. Capable of 45 watts per channel into an 8-ohm load, it is 50% more powerful and much cooler running than its predecessor.

Like all Parasound Z-series components, Zamp uses a standardized “half-width” rack-mount chassis that is just 1 rack space (1-3/4 inches) tall and 9-1/2 inches wide, half the width of a conventional audio component. This size is perfect for a compact bookshelf audio system or two-abreast in a standard 19-inch professional equipment rack.

Unlike other compact amplifiers, which typically employ low-cost single-chip IC amplifier modules, the Zamp v.3 uses fully discrete, direct-coupled DC servo circuitry, high speed bipolar output transistors, and a massive, high quality toroid power transformer. In addition to its 2 x 45 watts, 8-ohm rating (20 Hz – 20 kHz, both channels driven), Zamp v.3 delivers 60 watts per channel with 4-ohm loads, or can be bridged to provide over 90 watts mono into 8 ohms.

Parasound designed the Zamp v.3 with custom installation in mind, including features like a removable IEC power cord, and rear-panel 12 Volt trigger input and output. Its rear panel auto turn-on switch can also be set so it will power up automatically when an audio signal is present, with adjustable sensitivity, or for manual turn on and off from the front panel. The unit’s faceplate includes a headphone jack, and individual indicators for protection or high temperature fault as well as left and right channel status.
