Parasound Zamp v.3 Half-Rack Amp

Filed under: Amplifiers

Parasound has introduced a more powerful version of its ultra-compact Zamp zone amplifier, for use in custom installations and compact audio systems. The new Parasound Zamp v.3 is a stereo power amplifier capable of 45 watts per channel into an 8-ohm load, 50% more powerful and much cooler running than its popular predecessor, the Zamp v.2.

Like all Parasound Z series components, it 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 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. This product is truly a custom installation problem solver.

[ParasoundZampv3] 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 moe 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 attractive faceplate includes a headphone jack, and individual indicators for protection or high temperature fault as well as left and right channel status.

[ParasoundZampv3rear] 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. The front panels EIA rack mounting holes. An optional Zblank adaptor can be used to mount a single Zamp v.3 in a 19-inch rack, while the SBS side-by-side adaptor allows any two Parasound Z models to fit in one rack space. Each model also includes no-mar isolation feet for standalone use.

  • 60 watts RMS/channel 4-ohms
  • 90 watts RMS bridged mono 8-ohms
