HOW TO SET UP

CONNECT AUDIO INPUT to IN PORT ON WIIM PRO

The WiiM Pro features two distinct audio input interfaces: the analog LINE IN and the digital optical (TOSLINK) SPDIF IN.
This versatile device functions as both a preamplifier and a network audio transmitter through Wi-Fi or Ethernet. You have the capability to stream analog audio input from sources such as CD players, vinyl players, TVs, or computers to other WiiM Pro or Mini devices, as well as to AirPlay-enabled devices (using AirPlay Cast), either singly or in multiple combinations.

Scenario 1: Analog Audio Source Input (CD Player, Vinyl Player, or Computer)
Connect your source device to the WiiM Pro's LINE IN port using a line-in cable. One of two types' cable as the follows might be used, i.e., RCA to RCA or Aux to RCA.
Connect to WiiM Pro Line IN port

Connect to CD player, vinyl player, TV or computer

Steps to set up the WiiM Pro with the line-in input:
(Perform step 3/4/5 after WiiM Home App is installed)

1. Insert the line-in cable into the LINE IN port located at the back of the WiiM Pro.
2. Connect the other end of the cable to the AUX or LINE OUT port on your audio source device (CD player, vinyl player, TV, or computer).
3. In the WiiM Home app, navigate to the 'Browse' tab, choose 'Select source on device,' then opt for 'LINE IN' to set it as your audio distribution source.
4. For creating a multiroom music group with your WiiM Pro, access the Devices section in the WiiM Home app. Select the WiiM Pro linked to your LINE-IN device, tap the group button (displaying a "link" icon within a box) in the upper-right corner of the device box, and choose the WiiM Pro you wish to transmit audio to.
5. Once done, the music from the device connected to the WiiM Pro will play across your multiroom music group.

Scenario 2: Digital Audio Source Input (TV or PC)
Connect your source device to the WiiM Pro's SPDIF IN (optical) port using an optical cable.

Steps to set up the WiiM Pro with the SPDIF IN are the same as Line-in, replacing Line-in with SPDIF IN.
Notes:

• You can also enable "Autosense" on the WiiM Pro to automatically play your Line- In or Optical-In source when WiiM Pro detects a signal. You can enable this feature from the WiiM Home App.
• WiiM Pro has a built-in EQ to process the audio input based on your taste. You can also control the audio volume in the App remotely without adjusting your audio input.
• Some source devices may require a preamp. For example, some turntables do not have a preamp built-in, so you will need to connect your turntable to an external preamp and then connect the preamp to WiiM Pro.

CONNECT WIIM PRO'S AUDIO OUT PORT

The WiiM Pro features three distinct audio output interfaces that offer flexibility in connecting your DAC, amplifier, or powered speaker. These interfaces include the analog LINE out, the digital optical (TOSLINK), and the Coaxial port. It's important to note that the WiiM Pro is designed to output audio through a single one of these audio output options.
Setting Up WiiM Pro Audio Output:
(Note: Perform steps 3, 4, and 5 after installing the WiiM Home App)

1. Depending on your preferred audio equipment, select the appropriate connection method: RCA cable, optical cable (TOSLINK), or COAX.

5. To cast audio to a wide array of AirPlay 2-enabled devices, please select from the list of the AirPlay receivers on "Now Playing" UI or device settings.

Upon completion, the music from the connected device will play across your multiroom music group.
You can follow the same procedure using the SPDIF input port of the WiiM Pro if your source device offers a digital audio output via SPDIF.
Additionally, you can enable the "Autosense" feature on the WiiM Pro, allowing it to automatically play your Line-In or Optical-In source upon detection of a signal. This feature can be activated within the WiiM Home App.
The WiiM Pro features a built-in EQ to tailor audio input to your preferences. Moreover, you can control audio volume remotely through the app, eliminating the need to adjust the audio input directly.
Note that certain source devices may require a preamp. For instance, some turntables
lack a built-in preamp, necessitating connection to an external preamp before linking to the WiiM Pro.

AUDIO OUTPUT VIA LINE/SPDIF/COAX/BT OUT

There are three separate audio output interfaces on WiiM Pro that you can use to connect your DAC, Amplifier, or powered speaker. These are the analog LINE out, the digital optical (TOSLINK), and the Coaxial port. Please note that WiiM Pro only outputs audio to one of the audio outputs.
It's important to select the correct audio output port. Otherwise, you may not be able to hear the sound.
If you want the bit-perfect audio output, please use the digital audio output and enable the fixed volume output. You can do so from the device setting on the WiiM Home App.
Thus, you have two ways to control the volume of your system.

• Control volume from your AVR or amplifier (Fixed volume output)
• Control the volume from the WiiM Home App. To do so, you need to turn off the fixed volume output.

AUDIO OUTPUT VIA SPDIF/COAX/LINE OUT

• Depending on the output you prefer to use, plug the SPDIF/RCA/COAX end of the cable into the corresponding output port on the WiiM Pro.
• Open the WiiM Home App on your iOS or Android device.
• Start playing on the output devices.

AUDIO OUTPUT VIA BT OUT (BT sourcing mode)

• Open the WiiM Home App on your iOS or Android device.
• Select Device Tab, and tap the device setting gear icon.
• Tap the Audio Output setting and select Bluetooth to connect to an external Bluetooth device (such as an amplifier or speaker)
• Start playing music.

STREAM AUDIO TO WIIM PRO WITH BLUETOOTH

Bluetooth wireless technology lets you stream music from mobile devices such as smartphones, tablets, TV, and laptop computers. Before streaming music from a device, you must pair your mobile device to the WiiM Pro. You can put the WiiM Pro into the pairing mode by pressing and holding the volume '+' and '-' buttons together for 2 seconds.
Bluetooth supports A2DP and AVRCP profiles, and both SBC and AAC codecs are supported.

ADVANCED FEATURES

FIRMWARE UPDATES

• WiiM Pro updates automatically when connected to your Wi-Fi network.
• Upgrades happen from 2:00-5:00 a.m. in your time zone. During the silent upgrade, there will be no sound and no indication. Upon opening the App, you will see the latest updates made to WiiM Pro.

USE ETHERNET INSTEAD OF Wi-Fi

When the Ethernet cable is plugged in, and WiiM Pro can connect to your network via the Ethernet connection, it'll disable the Wi-Fi automatically and connect to the network via Ethernet only. You can check which network connection is used from the WiiM Home App > Browse Tab > Scroll down to the bottom, and check the select audio source section. You'll see the Ethernet instead of Wi-Fi when an Ethernet connection is used.
