Parasound has introduced a more powerful version of its ultra-compact Zamp zone amplifier for use in custom installations and compact audio systems. The Parasound Zamp v.3 is a stereo power amplifier capable of 45 watts per channel into an 8-ohm load, making it 50% more powerful and much cooler running than its popular predecessor, the Zamp v.2. 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. The amplifier’s small size also makes it ideal for unconventional and space-limited applications, including multi-room / multi-zone installations, PC and desktop audio, and bedroom or den stereo systems. 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. The unit’s attractive faceplate includes a headphone jack, and individual indicators for protection or high temperature fault as well as left and right channel status. The Zamp v.3 features gold-plated five-way binding posts for speaker connections, and line-level inputs and outputs for integration with other equipment. Rear panel level controls can be independently adjusted for each channel to ensure ideal gain staging with a variety of preamplifiers or multi-room controllers.
