Feature-Rich for it's Size

You can run the Zamp in stereo, or get two and run them both in bridged mono mode for more power. You can rack-mount this amp using the optional Parasound ZRK Kit, or even mount two side by side in a single rack space. The RCA stereo loop out makes it easy to daisy-chain multiple amps together.

Stereo gain controls on the rear panel let you dial in the lowest noise floor for your system. There's also a three-way switch for choosing how you want to turn the Zamp on and off — "audio" for automatic power-up when the amplifier senses an audio signal, "manual" for front button control, and "12V" to trigger the power from other components or controllers via 12-volt back-panel connections.

Plugging in to the front-panel 3.5mm headphone output disables the speaker output, so you can listen without disturbing the peace. And the detachable 3-prong power cord means you can upgrade to a better cable to clean up power feeding the amp.

Parasound's Most Affordable Amp

Parasound has been making the Zamp for over 20 years with very few changes. Their philosophy is that if you build it right the first time, there's no need to perpetually revise it.
