FiiO Q7 DSD512 MQA Balanced Portable DAC/Headphone Amp - Open Box

Yes, the FiiO Q7 can operate as a standalone DAC when connected to an external amplifier. Users have reported that by setting the device to line-out (LO) mode and using appropriate cables—such as a 4.4mm to dual XLR for balanced connections or a 6.3mm to dual RCA for unbalanced connections—the Q7 effectively serves as a DAC. Adjusting the line-out settings to either fixed or variable volume allows for integration into various audio setups.

Yes, the FiiO Q7 can be used with just a USB connection to a computer, such as a MacBook Pro M2, without connecting to the DC power supply or charging the internal battery. This setup allows for portable use without the need for external power sources. However, the available amplification modes may vary, and it's advisable to consult the user manual or contact FiiO support for specific details regarding power modes in this configuration.

The FiiO Q7's digital control core is powered by an upgraded ARM Cortex M4 processor, part of FiiO's self-developed digital control center. This processor efficiently manages tasks such as clock management, USB decoding, and optical decoding, optimizing the device's sound quality. Additionally, the Q7's design physically separates the digital and analog sections onto different boards with shielding, further enhancing sound purity by minimizing potential interference between components.
