Fosi Audio stereo amplifier ZA3-48V

An amplifier built from a passion for sound
The Fosi Audio ZA3-48V is a new generation of Hi-Fi stereo amplifier V3. Following the launch of the V3 amplifier, Fosi Audio has gathered countless responses from passionate audiophiles. Users of the V3 amplifier have expressed specific desires to improve the V3, and so the all-new ZA3 was born.

It is the first Fosi Audio amplifier to support both stereo and mono modes. At the same time, the ZA3 is the debut of symmetrical audio inputs, with combined XLR and 1/4" TRS connectors, and a pair of RCA inputs. 12V Trigger In serves you for seamless synchronization with other devices, or for easy one-click power management. The unit features Speaker Output (stereo, mono) and an output for an active Sub Out subwoofer.
