FAQs
Q: What kind of device is the WiiM Pro Plus?
The WiiM Pro Plus is a small gadget that combines a network music streamer, DAC, and digital hub. It allows you to stream high-quality audio from services, local libraries, or linked devices and output the audio (digital or analogue) to your speakers or amplifier.
Q: Why use a streamer instead of just playing music from a phone or computer?
Because even outdated stereo equipment can be transformed into a cutting-edge hi-fi system with a dedicated streamer like Pro Plus, which delivers improved audio quality, steadier playback, wide format support, and multi-room/airplay-style functionality.
Q: What audio quality does it support?
Although the conventional playback output is up to 192 kHz/24-bit using optical/coaxial or analogue output, the integrated DAC is a high-end AKM 4493SEQ that can decode audio files up to 768 kHz/32-bit PCM and DSD512.
Q: Does it output “bit-perfect” audio?
Yes, it ensures minimal signal deterioration by providing bit-perfect, lossless digital output when employing digital outputs (optical/coaxial).
Q: What streaming protocols and services does it support?
AirPlay 2, Chromecast Audio, DLNA/UPnP, Spotify Connect, Tidal Connect, Amazon Music, Qobuz, Deezer, internet radio, and more are all supported by the Pro Plus.
Q: Can it work in a multi-room or multi-zone setup?
To synchronise playback across rooms, Pro Plus can group with other compatible devices (such as additional Pro Plus units, other WiiM streams, or AirPlay/Chromecast-compatible devices).
Q: What connectivity options are available?
In addition to Bluetooth 5.1 for local audio input, the device has dual-band Wi-Fi (2.4 GHz & 5 GHz) and Ethernet (RJ45) for network streaming, analogue RCA line-out/in, digital optical and coaxial I/O, digital output for external DACs, and a 12 V trigger for integration with larger systems.
