Product Description

FiiO AM3 Balanced Power Amplifier Module is a replaceable upgraded amplifier unit that can be added and used with your FiiO X7 to further enhance the sound quality. Medium Power verion available as the AM2 which is also made for the X7.


The AM3 utilises the newly launched amp OPA1622 from Ti which is exclusively aimed at audio products. The OPA1622 is the newest addition to the Ti Burr-Brown Audio product line and is is an upgrade to the widely used OPA1612. In order to achieve full-channel balanced output there are six OPA1622 chips installed which enables the module to support both 2.5mm TRRS balanced output and 3.5mm standard single-end output with an ultra-low THD+N of -119.2dB (0.000018%), while driving a 32-Ohm load at 10-mW output power - 12 times better than the most similar competitive product.


Replacing the modules is extremely easy; simply using the Screwdriver that came with your X7 it is merely a matter of undoing 2 screws to remover the AM1 and replace it with the AM3. Although protection circuits are installed on the X7, it is still recommended to perform the module exchange when the X7 is turned off. The FiiO AM3 unit comes in a metal protective box which will protect which ever amp you choose to store in there.
