Overview
Linking sources through several interface types, this FiiO unit offers two output modes. It names headphones, receivers and Bluetooth devices among its compatible gear.
Three interface types and a choice of output modes are the reasons to look at it. The limitation is what the listing omits: no output power, no impedance range and no power supply.
Who it's for
A hi-fi desk with sources that offer RCA or XLR connections fits the interface set. Buyers who need output power figures, a wall adapter or a TV connection should check FiiO before ordering.
Pros and cons
- Three interface types
- Balanced output mode
- Single ended mode
- Output power not listed
- Power supply not named
- Only a quick start guide listed
Performance notes
Balanced connections cancel noise over longer cable runs, while single ended modes suit simple sources. Headphone output suitability depends on impedance and power, which the listing leaves out. Matching input types on both ends makes the signal chain simpler.
